CPR Techniques and Defibrillation

Study Notes

Ratio: 30:2 (30 compressions to 2 breaths) for adult, child, and infant
Compression depth: At least 2 inches (5 cm) for adults, 1/3 to 1/2 of the chest cavity for infants and children
Compression rate: 100-120 compressions per minute
Rescue breaths: Each breath should last approximately 1 second, with a volume of 500-600 mL
CPR sequence: Call 911/activate EMS, start CPR (compressions first), use AED (if available)

Automated External Defibrillator (AED): A device that analyzes heart rhythm and delivers a shock if necessary
AED use: Follow device instructions, ensure good electrode contact, stand clear during shock
AED contraindications: None, but avoid using AED on a person with a pulse or in a hazardous environment

Recognition: Inability to cough, speak, or breathe
Back blows: 5 rapid blows between the shoulder blades, repeat until object is dislodged
Abdominal thrusts: Quick upward thrusts, repeat until object is dislodged
Choking relief sequence: Back blows, abdominal thrusts, repeat until object is dislodged

Purpose: To provide oxygen to a person who is not breathing
Ratio: 1 breath every 5-6 seconds (10-12 breaths per minute)
Breath volume: 500-600 mL for adults, 200-300 mL for children and infants
Breath duration: 1 second per breath
Rescue breathing sequence: 2 breaths, then reassess the person's airway, breathing, and circulation (ABCs)

The ratio for CPR is 30:2 for adults, children, and infants, meaning 30 compressions to 2 breaths.
Compression depth should be at least 2 inches (5 cm) for adults and 1/3 to 1/2 of the chest cavity for infants and children.
The compression rate should be 100-120 compressions per minute.
Each rescue breath should last approximately 1 second, with a volume of 500-600 mL.
The CPR sequence involves calling 911/activating EMS, starting CPR with compressions, and using an AED (if available).

An Automated External Defibrillator (AED) is a device that analyzes heart rhythm and delivers a shock if necessary.
When using an AED, follow the device's instructions, ensure good electrode contact, and stand clear during the shock.
There are no contraindications for AED use, but avoid using it on a person with a pulse or in a hazardous environment.

Recognize cardiac arrest by checking for an unresponsive person who is not breathing and has no pulse.
Call 911/activate EMS immediately.
Start CPR with compressions and continue until the AED or EMS arrives.
If available, use an AED by following the device's instructions.
Continue care until EMS arrives or the person's heart starts beating again.

Recognize choking by checking for an inability to cough, speak, or breathe.
Provide back blows with 5 rapid blows between the shoulder blades, repeating until the object is dislodged.
If back blows are ineffective, use abdominal thrusts with quick upward thrusts, repeating until the object is dislodged.
The choking relief sequence involves back blows, followed by abdominal thrusts, until the object is dislodged.

The purpose of rescue breathing is to provide oxygen to a person who is not breathing.
The ratio for rescue breathing is 1 breath every 5-6 seconds (10-12 breaths per minute).
The breath volume should be 500-600 mL for adults and 200-300 mL for children and infants.
Each breath should last approximately 1 second.
The rescue breathing sequence involves providing 2 breaths, then reassessing the person's airway, breathing, and circulation (ABCs).
