The algorithm emphasizes minimally interrupted, high-quality chest compressions, early defibrillation for VF/VT, and clear team actions during rhythm checks, defibrillator charging, and drug administration. It outlines when to give adrenaline, when to provide amiodarone, and how to identify and correct potentially reversible causes.","Advanced Life Support Algorithm  \nLearning outcomes  \n􀀄􀀉 􀀍􀀈 􀀆 􀀇􀀊􀀋􀀌􀀅􀀈 􀀆 􀀃  \n􀀂 The function of the advanced life support (ALS) algorithm  \n􀀂 The importance of minimally interrupted high quality chest compressions  \n􀀂 The treatment of shockable and nonshockable rhythms  \n􀀂 When and how to give drugs during cardiac arrest  \n􀀂 The potentially reversible causes of cardiac arrest  \nIntroduction  \nHeart rhythms associated with cardiac arrest are divided into two groups: shockable rhythms (ventricular fibrillation / pulseless ventricular tachycardia (VF/VT)) and nonshockable rhythms (asystole and pulseless electrical activity (PEA)) . The principle difference in the management of these two groups of arrhythmias is the need for attempted defibrillation in patients with VF/VT. Subsequent actions , including chest compressions , airway management and ventilation , venous access , injection of adrenaline and the identification and correction of reversible factors , are common to both groups.  \nThe ALS algorithm (Figure 6. 1) is a standardised approach to cardiac arrest management. This has the advantage of enabling treatment to be delivered expediently, without protracted discussion. It enables each member of the resuscitation team to predict and prepare for the next stage in the patient’s treatment , further enhancing efficiency of the team. Although the ALS algorithm is applicable to most cardiac arrests , additional interventions may be indicated for cardiac arrest caused by special circumstances (see Chapter 12) .  \nThe interventions that unquestionably contribute to improved survival after cardiac arrest are prompt and effective bystander cardiopulmonary resuscitation (CPR) , uninterrupted , high quality chest compressions , and early defibrillation for VF/VT. The use of adrenaline has been shown to increase return of spontaneous circulation (ROSC) , but no resuscitation drugs or advanced airway interventions have been shown to increase survival to hospital discharge after cardiac arrest. Thus , although drugs and advanced airways are still included among ALS  \ninterventions , they are of secondary importance to highquality, uninterrupted chest compressions and early defibrillation.  \nShockable rhythms (VF/VT)  \nThe first monitored rhythm is VF/VT in approximately 25% of cardiac arrests , both in-or out-of-hospital. VF/VT will also occur at some stage during resuscitation in about 25% of cardiac arrests with an initial documented rhythm of asystole or PEA.  \nTreatment of shockable rhythms (VF/VT)  \n1. Confirm cardiac arrest-check for signs of life or if trained to do so , breathing and pulse simultaneously.  \n2. Call resuscitation team.  \n3. Perform uninterrupted chest compressions while applying self-adhesive defibrillation/monitoring padsone below the right clavicle and the other in the V6 position in the midaxillary line.  \n4. Plan actions before pausing CPR for rhythm analysis and communicate these to the team.  \n5. Stop chest compressions; confirm VF from the ECG.  \n6. Resume chest compressions immediately;  \nsimultaneously, the designated person selects the appropriate energy on the defibrillator (150-200 J biphasic for the first shock and 150-360 J biphasic for subsequent shocks) and presses the charge button (Figure 6.2) .  \n7. While the defibrillator is charging , warn all rescuers other than the individual performing the chest compressions to “stand clear” and remove any oxygen delivery device as appropriate.  \n8. Once the defibrillator is charged , tell the rescuer doing the chest compressions to ”stand clear”; when clear, give the shock (Figure 6.3) .  \n9. Without reassessing the rhythm or feeling for a pulse , restart CPR using a ratio of 30:2 , starting with chest compressions.  \n10. Continue CPR for 2 min; the team leader prepares the team for the next pause in CPR.  \nADVANCED LIFE SUPPORT  \n4  \nAdult Advanced Life Support  \nUnresponsive?  \nNot breathing or only occasional gasps  \nAssess rhythm  \nDuring CPR  \nx Ensure h","cbCaipuSf0xxVPoP","https://ap.wps.com/l/cbCaipuSf0xxVPoP","pdf",1004400,15,"English","en",105,"# Adult Advanced Life Support\n## Learning outcomes\n## Introduction\n## Shockable rhythms (VF/VT)\n## Treatment of shockable rhythms (VF/VT)\n## Reversible causes\n## ROSC assessment and switching algorithms","[{\"question\":\"How does the ALS algorithm differentiate between shockable and nonshockable rhythms?\",\"answer\":\"It separates cardiac arrest rhythms into shockable (VF/VT) and nonshockable (asystole, PEA).
