- 1Chest compressionsLead to 02 perfusion to the heart and brain
patients need to be on a hard and flat surface for optimal compressions
Perform 100-120 compressions per minute at a depth of 5-6 cm with adequate chest recoil with each compression
It is adequate to limit interruptions during compressions
To prevent fatigue, individuals providing compressions can change every 2 minutes (or after five cycles of compressions) at a rate of 30:2 compressions/ventilations with a maximum of 5 seconds for the change to occur - 2Airwayuse the head tilt/Chin lift maneuver to open airway or place an artificial airway if the patient has no evidence of head or neck trauma
- 3Rescue breathsPrimary function is oxygenation, with secondary function to remove co2
Compressions should supercede airways or rescue breaths
Follow a compression/ventilation ratio of 30:2
give enough tidal volume to witness. chest rise
Bag-mask ventilation should be applied when there is more than 1 rescuer - 4Rapid defibrillator using a manual or automated external defibrillatorSuccessful defibrillation is defined as 5 or greater of termination of arrhythmias after a shock is being delivered
Chest compressions should be stopped while a shock is being delivered, shouldd continue while defibrillator is charging, and should resume immediately after shock delivery
Most AEDs are biphasic (energy 120J or 200J) - 5End tidal carbon dioxide (ETCO2)Is the concentration of co2 in exhaled airat the end of expiration
-During cardiac arrest, ETCO2 decrease because there is no flow through pulmonary circulation
ETCO2<10mmHg during CPR in intubated patients make ROSC unlikely - 6Arrest RhythmsThe four primary arrest rhythms are divided to 2 groups:
Shockable rhythms (VF and pulseless VT)
Nonshockable(PEA and asystole) - 7—
