Module 4 - 2-Rescuer Adult BLS

-For 2-rescuer BLS, you will use the bag-mask device. -A bag-mask device is used to provide positive-pressure ventilation to a victim who is not breathing or not breathing normally. It consists of a bag attached to a face mask. If the bag is self-inflating, a bag-mask device may be used with or without an oxygen supply. If not attached to an oxygen flow, it provides about 21% oxygen from room air. Some bag-mask devices include a 1-way valve. The type of valve may vary from on device to another.

-same as pocket mask -give 2 breaths after every set of 30 compressions -deliver each breathe over 1 second, with just enough volume to make the chest rise. -avoid excessive ventilation

First rescuer: -chest compressions, count out loud, deliver breaths Second rescuer: -power up AED and attach pads

Step 1: verify scene safety Step 2: Check for responsiveness, if unresponsive shout for nearby help. First rescuer remains with victim, second activates emergency response system and retrieves AED and emergency equipment. Step 3: look for no breathing/gasping and check for pulse (simultaneously). If there is normal breathing and a pulse, monitor until emergency responders arrive. If there is no normal breathing but a pulse, provide rescue breathing. Step 4: If there is no breathing or only gasping and no pulse, begin CPR (cycles of 30 compressions and 2 breaths). Use AED as soon as available. Step 5: When AED arrives check the rhythm. Is the rhythm shockable?

critical characteristics: -push hard & fast=compress at a rate of 100-120/min with a depth of at least 2 inches -allow complete chest recoil, and dont lean on chest after compressions -minimize interruptions in compressions to less than 10 seconds -give effective breaths that make the chest rise and avoid excessive ventilation
