When to Activate Emergency Response System
If possible, send someone to activate the Emergency Response System, and begin CPR immediately. As soon as it’s available use an AED. If you’re not with someone (and you do not have a mobile phone) leave the patient to activate the Emergency Response System while also retrieving an AED.
Team Resuscitation: HCP’s can use flexibility when activating the emergency response to fit the provider’s clinical setting, for better management.
Adult and Adolescents CPR
Scene Safety and Recognition of Cardiac Arrest: Check for safety and responsiveness, no breathing, gasping, check pulse for more than 5 seconds but within 10 seconds (breathing and pulse check can occur simultaneously).
Check Pulse: You can check the pulse by placing 2 fingers on the carotid artery (press your index and 3rd finger on the side of the neck, against the windpipe). You can also check the wrist by placing the same 2 fingers on the inside of the wrist below the thumb.
C is for Circulation – Adult and Adolescent Compressions
Circulation - chest compressions circulate the blood within the patient. It's important to place your hands correctly upon the patient’s chest. Chest Compression Tempo: the correct tempo that should be performed matches the song “Staying Alive.” Make sure to push hard and fast to that song’s tempo.
Compression-ventilation ratio without Advanced Airway
Make sure the adult or adolescent is resting upon a solid-firm surface. Perform chest compressions on the lower half of the breastbone (sternum). Once in position, lock your elbows and use your body’s weight to compress at least 2 inches (5 cm) upon the patient’s chest. Do not lean on the patient’s chest in between compressions and make sure the chest completely recoils. Limit all interruptions to less than 10 seconds while performing CPR.
It’s important to note: that when performing chest compressions on an adult or adolescent you should compress at least 2 inches (5 cm). The compression rate is 100-120/min. 2 Rescuers: Perform tasks simultaneously. Administer compressions over breathing 30:2.
Chest Compression Fraction: is the total percentage of resuscitation time when performed by the rescuer(s) during cardiac arrest. Whether intended or unintended interruptions (such as real-world delays) occur Chest Compression Fraction aims to minimize pauses in chest compressions. Chest Compression Fraction Goal: target of at least 60%.
Compression-ventilation ratio with Advanced Airway
- Continuous compressions at a rate of 100-120/min
- 1 breath every 6 seconds (10 breaths/min)
Chest compressions should be performed on patients who are obese.
Chest compressions should be performed on pregnant women and a modification if the pregnant woman’s fundus height is at or above the level of the umbilicus. If the woman’s fundus height is at or above the umbilicus, then High-quality CPR with manual left uterine displacement will be beneficial for relieving aortocaval compression during, the chest compression task. To perform manual left uterine displacement: push the uterus to the patient’s left side with 1 hand while still providing CPR.
A is for Airway - Clear the Airway
Airway - Make sure the patient is on a solid surface (on the backside). Next, kneel next to the patient’s neck and shoulders. Open the patient’s airway by tilting the head back with the palm of one hand while gently lifting the chin with the other hand. For no more than 10 seconds, check for life: listen for any sounds, put your cheek next to the patient’s mouth to feel any breaths while also looking for any motion. Rescuers can check steps simultaneously. If the patient is assumed lifeless begin Mouth-to-Mouth.
Jaw-Thrust Maneuver: kneel above the patient’s head, rest your elbows on the surface, place 1 hand on both sides of the patient’s jaw, stabilize the patient’s head with your forearms, use your index finger to lower the patient’s jaw as you use your thumb to retract the patient’s lower lip. If the patient is assumed lifeless, perform mouth-to-mouth.
B is for Breathing - Mouth-to-Mouth
Rescue Breathing is widely known to be performed mouth-to-mouth—it can also be performed mouth-to-nose but in rare cases. While still performing the Airway technique pinch the patient’s nose shut. With a complete seal over the patient’s mouth, with your mouth, breathe until you see the chest inflate. If the chest does not inflate repeat the Airway technique. Once the chest inflates, breathe into the patient a second time (30:2).
Once the breathing technique is applied, continue Circulation, Airway, Breathing (C-A-B’s).
Rescuers Should Never
- Compress slower than 100/min or faster than 120/min
- Compress in depth less than 2 inches (5 cm) or more than 2.4 (6 cm)
- Lean on victim’s chest during compressions
- Allow interruption during compressions more than 10 seconds
- Provide excessive ventilation during breathing task, ie: excessive breathing with force or too many breaths
