If the patient presents with SVT, the primary goal of treatment is to quickly identify and treat patients who are hemodynamically unstable (ischemic chest pain, altered mental status, shock, hypotension, acute heart failure) or symptomatic due to the arrhythmia. No large RCT evaluating different treatment strategies for patients suffering from acute cocaine toxicity exists. The effect of individual CPR quality metrics or interventions is difficult to evaluate because so many happen concurrently and may interact with each other in their effect. One RCT in OHCA comparing SGA (with iGel) to ETI in a nonphysician-based EMS system (ETI success, 69%) found no difference in survival or survival with favorable neurological outcome at hospital discharge. The intent of precordial thump is to transmit the mechanical force of the thump to the heart as electric energy analogous to a pacing stimulus or very low-energy shock (depending on its force) and is referred to as, Fist, or percussion, pacing is administered with the goal of stimulating an electric impulse sufficient to cause depolarization and contraction of the myocardium, resulting in a pulse. 1. Synchronized cardioversion is recommended for acute treatment in patients with hemodynamically unstable SVT. In the ASPIRE trial (1071 patients), use of the load-distributing band device was associated with similar odds of survival to hospital discharge (adjusted odds ratio [aOR], 0.56; CI, 0.311.00; A 2013 Cochrane review of 10 trials comparing ACD-CPR with standard CPR found no differences in mortality and neurological function in adults with OHCA or IHCA. Many of these were reviewed in an evidence update provided in the 2020 COSTR for ALS.2 Many uncertainties within the topic of TTM remain, including whether temperature should vary on the basis of patient characteristics, how long TTM should be maintained, and how quickly it should be started. When VF/VT has been present for more than a few minutes, myocardial reserves of oxygen and other energy substrates are rapidly depleted. We recommend avoiding hypoxemia in all patients who remain comatose after ROSC. What is the best approach to rewarming postarrest patients after treatment with targeted temperature Due to the potential effects of intrinsic positive end-expiratory pressure (auto-PEEP) and risk of barotrauma in an asthmatic patient with cardiac arrest, a ventilation strategy of low respiratory rate and tidal volume is reasonable. 3. Clinicians must determine if the tachycardia is narrow-complex or wide-complex tachycardia and if it has a regular or irregular rhythm. Many of these techniques and devices require specialized equipment and training. Long-term anticoagulation may be necessary for patients at risk for thromboembolic events based on their CHA2 DS2 - VASc score. When significant CAD is observed during post-ROSC coronary angiography, revascularization can be achieved safely in most cases.5,7,9 Further, successful PCI is associated with improved survival in multiple observational studies.2,6,7,10,11 Additional benefits of evaluation in the cardiac catheterization laboratory include discovery of anomalous coronary anatomy, the opportunity to assess left ventricular function and hemodynamic status, and the potential for insertion of temporary mechanical circulatory support devices. 5. Case reports and at least 1 retrospective observational study have been published on survival after ECMO in patients presenting with refractory shock from -adrenergic blocker overdose. In patients with calcium channel blocker overdose who are in refractory shock, administration of high-dose insulin with glucose is reasonable. To effectively give rescue breaths, it's essential that the person's airway is open and clear. 3. The 2020 Guidelines are organized into knowledge chunks, grouped into discrete modules of information on specific topics or management issues.5 Each modular knowledge chunk includes a table of recommendations that uses standard AHA nomenclature of COR and LOE. What do survivor-derived outcome measures of the impact of cardiac arrest survival look like, and how Cardiac arrest survivors, like many survivors of critical illness, often experience a spectrum of physical, neurological, cognitive, emotional, or social issues, some of which may not become apparent until after hospital discharge. Because immediate ROSC cannot always be achieved, local resources for a perimortem cesarean delivery should be summoned as soon as cardiac arrest in a woman in the second half of pregnancy is recognized. This link is provided for convenience only and is not an endorsement of either the linked-to entity or any product or service. Although contradictory evidence exists, it may be reasonable to avoid the use of pure -adrenergic blocker medications in the setting of cocaine toxicity. Finally, case reports and case series using ECMO in maternal cardiac arrest patients report good maternal survival.16 The treatment of cardiac arrest in late pregnancy represents a major scientific gap. Time to drug in IHCA is generally much shorter, and the effect of epinephrine on outcomes in the IHCA population may therefore be different. We recommend that epinephrine be administered for patients in cardiac arrest. Since the last time these recommendations were formally reviewed, The administration of hypertonic (8.4%, 1 mEq/ mL) sodium bicarbonate solution for treatment of sodium channel blockade due to TCAs and other toxicants is supported by human observational studies. Advanced airways is a tube which is inserted in the mouth or nose, during this continuous CPR at the rate of 100 per minute is given. Active compression-decompression CPR might be considered for use when providers are adequately trained and monitored. do they differ from current generic or clinician-derived measures? Opioid overdoses deteriorate to cardiopulmonary arrest because of loss of airway patency and lack of breathing; therefore, addressing the airway and ventilation in a periarrest patient is of the highest priority. There is insufficient evidence to recommend the routine use of extracorporeal CPR (ECPR) for patients with cardiac arrest. Airway, ventilation, and oxygenation are particularly important in the setting of pregnancy because of increased maternal metabolism and decreased functional reserve capacity due to the gravid uterus, making pregnant patients more prone to hypoxia. Interposed abdominal compression CPR is a 3-rescuer technique that includes conventional chest compressions combined with alternating abdominal compressions. Approximately 1.2% of adults admitted to US hospitals suffer in-hospital cardiac arrest (IHCA).1 Of these patients, 25.8% were discharged from the hospital alive, and 82% of survivors have good functional status at the time of discharge. Nine observational studies evaluated rhythmic/ periodic discharges. Deliver each breath over 1 second. Recognition of cardiac arrest by healthcare providers includes a pulse check, but the importance of not prolonging efforts to detect a pulse is emphasized. 3. When providing rescue breaths, it may be reasonable to give 1 breath over 1 s, take a regular (not deep) breath, and give a second rescue breath over 1 s. 4. The American Heart Association requests that this document be cited as follows: Panchal AR, Bartos JA, Cabaas JG, Donnino MW, Drennan IR, Hirsch KG, Kudenchuk PJ, Kurz MC, Lavonas EJ, Morley PT, ONeil BJ, Peberdy MA, Rittenberger JC, Rodriguez AJ, Sawyer KN, Berg KM; on behalf of the Adult Basic and Advanced Life Support Writing Group. We recommend structured assessment for anxiety, depression, posttraumatic stress, and fatigue for cardiac arrest survivors and their caregivers. Breath stacking in an asthma patient with limited ability to exhale can lead to increases in intrathoracic pressure, decreases in venous return and coronary perfusion pressure, and cardiac arrest. Applying Class of Recommendation and Level of Evidence to Clinical Strategies, Interventions, Treatments, or Diagnostic Testing in Patient Care (Updated May 2019)*, Table 3. Resuscitation causes, processes, and outcomes are very different for OHCA and IHCA, which are reflected in their respective Chains of Survival (Figure 1). In patients with narrow-complex tachycardia who are refractory to the measures described, this may indicate a more complicated rhythm abnormality for which expert consultation may be advisable. Chest compressions are the most critical component of CPR, and a chest compressiononly approach is appropriate if lay rescuers are untrained or unwilling to provide respirations. In patients with confirmed pulmonary embolism as the precipitant of cardiac arrest, thrombolysis, surgical embolectomy, and mechanical embolectomy are reasonable emergency treatment options. In patients with calcium channel blocker overdose who are in refractory shock, administration of calcium is reasonable. This is clearly covered topic if you attend a BLS Provider class. 7272 Greenville Ave. 6. For shockable rhythms, trial protocols have directed that epinephrine be given after the third shock. Effective ventilation of the patient with a tracheal stoma may require ventilation through the stoma, either by using mouth-to-stoma rescue breaths or by use of a bag-mask technique that creates a tight seal over the stoma with a round, pediatric face mask. In patients with -adrenergic blocker overdose who are in refractory shock, administration of IV glucagon is reasonable. Cardiac arrest occurs after 1% to 8% of cardiac surgery cases.18 Etiologies include tachyarrhythmias such as VT or VF, bradyarrhythmias such as heart block or asystole, obstructive causes such as tamponade or pneumothorax, technical factors such as dysfunction of a new valve, occlusion of a grafted artery, or bleeding. CPR indicates cardiopulmonary resuscitation; IHCA, in-hospital cardiac arrest; and OHCA, out-of-hospital cardiac arrest. While ineffective in terminating ventricular arrhythmias, adenosines relatively short-lived effect on blood pressure makes it less likely to destabilize monomorphic VT in an otherwise hemodynamically stable patient. 2. 1. Drug administration by central venous access (by internal jugular or subclavian vein) achieves higher peak concentrations and more rapid circulation times than drugs administered by peripheral IV do, Endotracheal drug administration is regarded as the least-preferred route of drug administration because it is associated with unpredictable (but generally low) drug concentrations. Does avoidance of hyperoxia in the postarrest period lead to improved outcomes? 2. 3. The theory is that the heart will respond to electric stimuli by producing myocardial contraction and generating forward movement of blood, but clinical trials have not shown pacing to improve patient outcomes. Manual stabilization can decrease movement of the cervical spine during patient care while allowing for proper ventilation and airway control. Nonvasopressor medications during cardiac arrest. A systematic review of the literature evaluated all case reports of cardiac arrest in pregnancy about the timing of PMCD, but the wide range of case heterogeneity and reporting bias does not allow for conclusions. Accurate neurological prognostication in brain-injured cardiac arrest survivors is critically important to ensure that patients with significant potential for recovery are not destined for certain poor outcomes due to care withdrawal. Although data specific to patients with ROSC after cardiac arrest from anaphylaxis was not identified, an observational study of anaphylactic shock suggests that IV infusion of epinephrine (515 g/min), along with other resuscitative measures such as volume resuscitation, can be successful in the treatment of anaphylactic shock. When performed with other prognostic tests, it may be reasonable to consider bilaterally absent N20 somatosensory evoked potential (SSEP) waves more than 24 h after cardiac arrest to support the prognosis of poor neurological outcome. Studies of mechanical CPR devices have not demonstrated a benefit when compared with manual CPR, with a suggestion of worse neurological outcome in some studies. Circulation. The only time you should do continuous compressions is when you have secured an advanced airway such as an ET tube. This protocol is supported by the surgical societies. High-dose epinephrine is not recommended for routine use in cardiac arrest. A 2020 ILCOR systematic review identified 3 studies involving 57 total patients that investigated the effect of hand positioning on resuscitation process and outcomes. In nonintubated patients, a specific end-tidal CO. 1. 1 During the prearrest and postarrest periods, the patient will require support of oxygenation and ventilation with tidal volumes and respiratory rates that . Once an advanced airway is emplaced and confirmed, chest compressions should be performed continuously at a rate of at least 100 per minute. responsible for a large proportion of opioid overdose? 1. This topic last received formal evidence review in 2010.5. -Adrenergic receptor antagonists (-adrenergic blockers) and L-type calcium channel antagonists (calcium channel blockers) are common antihypertensive and cardiac rate control medications. Much of the evidence examining the effectiveness of airway strategies comes from radiographic and cadaver studies. More research in this area is clearly needed. Epinephrine has been hypothesized to have beneficial effects during cardiac arrest primarily because of its -adrenergic effects, leading to increased coronary and cerebral perfusion pressure during CPR. This may include vasopressor agents such as epinephrine (discussed in Vasopressor Medications During Cardiac Arrest) as well as drugs without direct hemodynamic effects (nonpressors) such as antiarrhythmic medications, magnesium, sodium bicarbonate, calcium, or steroids (discussed here). This topic last received formal evidence review in 2015.24, Hypoxic-ischemic brain injury is the leading cause of morbidity and mortality in survivors of OHCA and accounts for a smaller but significant portion of poor outcomes after resuscitation from IHCA.1,2 Most deaths attributable to postarrest brain injury are due to active withdrawal of life-sustaining treatment based on a predicted poor neurological outcome. Should severely hypothermic patients in cardiac arrest receive epinephrine or other resuscitation Does the treatment of nonconvulsive seizures, common in postarrest patients, improve patient In addition to defibrillation, several alternative electric and pseudoelectrical therapies have been explored as possible treatment options during cardiac arrest. The clinical manifestations of bradycardia can range from an absence of symptoms to symptomatic bradycardia (bradycardia associated with acutely altered mental status, ischemic chest discomfort, acute heart failure, hypotension, or other signs of shock that persist despite adequate airway and breathing). These procedures are described more fully in Part 2: Evidence Evaluation and Guidelines Development. Disclosure information for writing group members is listed in Appendix 1(link opens in new window). If an arterial line is in place, an abrupt increase in diastolic pressure or the presence of an arterial waveform during a rhythm check showing an organized rhythm may indicate ROSC. In the rare situation when a lone rescuer must leave the victim to dial EMS, the priority should be on prompt EMS activation followed by immediate return to the victim to initiate CPR. This begins with opening the airway followed by delivery of rescue breaths, ideally with the use of a bag-mask or barrier device. If the chest is compressed during ventilations, most of the Continue reading "CPR with an Advanced Airway" Minimizing disruptions in CPR surrounding shock administration is also a high priority. Can point-of-care cardiac ultrasound, in conjunction with other factors, inform termination of Activation of emergency response system 3. Step 1: Power on the AED if needed - Follow the prompts (as a guide to next steps) Step 2: Choose adult pads for victim 8 years of age and older - Attack the adhesive AED pads to the victim's bare chest - Follow the diagrams on the pads Step 3: When AED prompts you, clear the victim during analysis. In the setting of head and neck trauma, a head tiltchin lift maneuver should be performed if the airway cannot be opened with a jaw thrust and airway adjunct insertion. and 4. Synchronized cardioversion is recommended for acute treatment in patients with hemodynamically stable SVT when vagal maneuvers and pharmacological therapy is ineffective or contraindicated. 2. 4. The prompt initiation of CPR is perhaps the most important intervention to improve survival and neurological outcomes. After initial stabilization, care of critically ill postarrest patients hinges on hemodynamic support, mechanical ventilation, temperature management, diagnosis and treatment of underlying causes, diagnosis and treatment of seizures, vigilance for and treatment of infection, and management of the critically ill state of the patient. Whether resumption of CPR immediately after shock might reinduce VF/VT is controversial.52-54 This potential concern has not been borne out by any evidence of worsened survival from such a strategy. Clinical trials in resuscitation are sorely needed. 1. Since last addressed by the 2010 Guidelines, a 2013 systematic review found little evidence to support the routine use of calcium in undifferentiated cardiac arrest, though the evidence is very weak due calcium as a last resort medication in refractory cardiac arrest. The combitube has two separate balloons that must be inflated and two separate ports. Along with providing standard BLS and ALS treatment, next steps include preventing additional evaporative heat loss by removing wet garments and insulating the victim from further environmental exposures. In addition to standard ACLS, several therapies have long been recommended to treat life-threatening hyperkalemia. Administration of IV amiodarone, procainamide, or sotalol may be considered for the treatment of wide-complex tachycardia. It may be reasonable to use physiological parameters such as arterial blood pressure or end-tidal CO. 1. Do neuroprotective agents improve favorable neurological outcome after arrest? In a recent meta-analysis of 2 published studies (10 178 patients), only 0.01% (95% CI, 0.00%0.07%) of patients who fulfilled the ALS termination criteria survived to hospital discharge. Symptoms typically occur within minutes, and findings may include arrhythmias, apnea, hypotension with bradycardia, seizures, and cardiovascular collapse.1 Lactic acidosis is a sensitive and specific finding.2,3 Immediate antidotes include hydroxocobalamin and nitrites; however, the former has a much better safety profile. 2. A randomized trial investigating this question is ongoing (NCT02056236). Operationally, the timing for prognostication is typically at least 5 days after ROSC for patients treated with TTM (which is about 72 hours after normothermia) and should be conducted under conditions that minimize the confounding effects of sedating medications. Although cardiac arrest due to carbon monoxide poisoning is almost always fatal, studies about neurological sequelae from less-severe carbon monoxide poisoning may be relevant. An IV dose of 0.05 to 0.1 mg (5% to 10% of the epinephrine dose used routinely in cardiac arrest) has been used successfully for anaphylactic shock. A recent consensus statement on this topic has been published by the Society of Thoracic Surgeons.9, This topic last received formal evidence review in 2010.35These recommendations were supplemented by a 2017 review published by the Society of Thoracic Surgeons.9. 2. There is concern that delivery of chest compressions without assisted ventilation for prolonged periods could be less effective than conventional CPR (compressions plus breaths) because the arterial oxygen content will decrease as CPR duration increases. In patients with -adrenergic blocker overdose who are in shock refractory to pharmacological therapy, ECMO might be considered. Because of their negative inotropic effect, nondihydropyridine calcium channel antagonists (eg, diltiazem, verapamil) may further decompensate patients with left ventricular systolic dysfunction and symptomatic heart failure. In adult CPR, 100 to 120 chest compressions per minute at a depth of at least 2 inches, but no greater than 2.4 inches, should be provided. Each of these resulted in a description of the literature that facilitated guideline development. Shout for nearby help/activate the resuscitation team; the provider can activate the resuscitation team at this time or after checking for breathing and pulse. Recent evidence, however, suggests that the risk of major bleeding is not significantly higher in cardiac arrest patients receiving thrombolysis. 1. 5. receiving CPR with ventilation? . In cases of suspected cervical spine injury, healthcare providers should open the airway by using a jaw thrust without head extension. 1. A number of key components have been defined for high-quality CPR, including minimizing interruptions in chest compressions, providing compressions of adequate rate and depth, avoiding leaning on the chest between compressions, and avoiding excessive ventilation.1 However, controlled studies are relatively lacking, and observational evidence is at times conflicting. This challenge was faced in both the 2010 Guidelines and 2015 Guidelines Update processes, where only a small percent of guideline recommendations (1%) were based on high-grade LOE (A) and nearly three quarters were based on low-grade LOE (C).1. 5. thrombolysis during resuscitation? Pressing down and releasing is 1 compression. How is cpr performed differently when an advanced airway is in place Answer: Answer: Once an advanced airway is in place rescuers are no longer delivering cycles of CPR. Conversely, a wide-complex tachycardia can also be due to VT or a rapid ventricular paced rhythm in patients with a pacemaker. 1. In postcardiac surgery patients with asystole or bradycardic arrest in the ICU with pacing leads in place, pacing can be initiated immediately by trained providers. Urgent direct-current cardioversion of new-onset atrial fibrillation in the setting of acute coronary syndrome is recommended for patients with hemodynamic compromise, ongoing ischemia, or inadequate rate control. To open a person's airway, do the following: Place your hand on their . Explanation: I hope This helps!! response. Why is this? Although there are no controlled studies, several case reports and small case series have reported improvement in bradycardia and hypotension after glucagon administration. The combination of active compression-decompression CPR and impedance threshold device may be reasonable in settings with available equipment and properly trained personnel. Determining the utility of such physiological monitoring or diagnostic procedures is important. It is reasonable to immediately resume chest compressions after shock delivery for adults in cardiac arrest in any setting. cardiac arrest with shockable rhythm? 1. It is important to underscore that while cough CPR by definition cannot be used for an unconscious patient, it can be harmful in any setting if diverting time, effort, and attention from performing high-quality CPR. Routine measurement of arterial blood gases during CPR has uncertain value. The half-life of flumazenil is shorter than many benzodiazepines, necessitating close monitoring after flumazenil administration.2 An alternative to flumazenil administration is respiratory support with bag-mask ventilation followed by ETI and mechanical ventilation until the benzodiazepine has been metabolized. ECPR refers to the initiation of cardiopulmonary bypass during the resuscitation of a patient in cardiac arrest. Systematic Review Most studies used young, healthy patients but no current method to identify ideal patients. Cardiac arrest survivors, their families, and families of nonsurvivors may be powerful advocates for community response to cardiac arrest and patient-centered outcomes. A wide-complex tachycardia can be regular or irregularly irregular and have uniform (monomorphic) or differing (polymorphic) QRS complexes from beat to beat. Postcardiac arrest care is a critical component of the Chain of Survival and demands a comprehensive, structured, multidisciplinary system that requires consistent implementation for optimal patient outcomes. The suggested timing of the multimodal diagnostics is shown here. overdose with naloxone? 3. 1. Acknowledging these data, the use of mechanical CPR devices by trained personnel may be beneficial in settings where reliable, high-quality manual compressions are not possible or may cause risk to personnel (ie, limited personnel, moving ambulance, angiography suite, prolonged resuscitation, or with concerns for infectious disease exposure). One large RCT in OHCA comparing bag-mask ventilation with endotracheal intubation (ETI) in a physician-based EMS system showed no significant benefit for either technique for 28-day survival or survival with favorable neurological outcome. Magnesium may be considered for treatment of polymorphic VT associated with a long QT interval (torsades de pointes). 2. The majority of recommendations are based on Level C evidence, including those based on limited data (123 recommendations) and expert opinion (31 recommendations). In some observational studies, improved outcomes have been noted in victims of cardiac arrest who received conventional CPR (compressions and ventilation) compared with those who received chest compressions only. Furthermore, many research studies have methodological limitations including small sample sizes, single-center design, lack of blinding, the potential for self-fulfilling prophecies, and the use of outcome at hospital discharge rather than a time point associated with maximal recovery (typically 36 months after arrest).3. Regardless of the underlying QT interval, all forms of polymorphic VT tend to be hemodynamically and electrically unstable. Peer reviewer feedback was provided for guidelines in draft format and again in final format. Lie the baby/infant on their back. 6. 7. The effectiveness of active compression-decompression CPR is uncertain. Discordance in goals of care between clinicians and families/surrogates has been reported in more than 25% of critically ill patients. Cardiac arrest results in heterogeneous injury; thus, death can also result from multiorgan dysfunction or shock.

The Chain of Survival, introduced in Major Concepts, is now expanded to emphasize the important component of survivorship during recovery from cardiac arrest, requires coordinated efforts from medical professionals in a variety of disciplines and, in the case of OHCA, from lay rescuers, emergency dispatchers, and first responders. Cough CPR is described as repeated deep breaths followed immediately by a cough every few seconds in an attempt to increase aortic and intracardiac pressures, providing transient hemodynamic support before a loss of consciousness. Answer the dispatchers questions, and follow the telecommunicators instructions. Recommendations 1, 2, and 3 are supported by the 2020 CoSTR for BLS.4 Recommendation 4 last received formal evidence review in 2010.17, Recommendations 1 and 4 are supported by the 2020 CoSTR for BLS.4 Recommendations 2, 3, 5, and 6 last received formal evidence review in 2015.31, Recommendations 1, 2, and 3 are supported by the 2020 CoSTR for BLS.4 Recommendation 4 last received formal evidence review in 2010.44, These recommendations are supported by the 2020 CoSTRs for BLS and ALS.4,49. Send the second person to retrieve an AED, if one is available. The literature supports prioritizing defibrillation and CPR initially and giving epinephrine if initial attempts with CPR and defibrillation are not successful. reflex, and myoclonus/status myoclonus? Since initial efforts for maternal resuscitation may not be successful, preparation for PMCD should begin early in the resuscitation, since decreased time to PMCD is associated with better maternal and fetal outcomes. We suggest recording EEG in the presence of myoclonus to determine if there is an associated cerebral correlate. In some instances, prognostication and withdrawal of life support may appropriately occur earlier because of nonneurologic disease, brain herniation, patients goals and wishes, or clearly nonsurvivable situations. 2. The value of artifact-filtering algorithms for analysis of electrocardiogram (ECG) rhythms during chest compressions has not been established. The dedicated rescuer who provides manual abdominal compressions will compress the abdomen midway between the xiphoid and the umbilicus during the relaxation phase of chest compression. We recommend that the findings of a best motor response in the upper extremities being either absent or extensor movements not be used alone for predicting a poor neurological outcome in patients who remain comatose after cardiac arrest.
