Study Notes

Child CPR and Choking

Administer 1 breath every 3 to 5 seconds for a child gasping for breath but with a pulse of 100 bpm.
Initiate CPR with compressions for a child not breathing but with a pulse of 50 bpm.
Mild airway obstruction signs in a child/adult: forceful cough, wheezing between coughs, breathing.
Severe airway obstruction signs in a child/adult: high-pitched noises during inhalation, poor air exchange, cyanosis around the lips.
In a 2-year-old choking victim, if the child can cough forcefully, do not interfere and do not give back blows if the child is responsive.

Infant CPR and Choking

Begin CPR for an unresponsive infant who was choking.
If an infant appears to be choking but is coughing effectively, just monitor them.
Relieve choking efforts should cease when obstruction is removed, the victim is unresponsive, or breathing returns to normal.

CPR Techniques

For a responsive choking infant with severe obstruction: alternate between back slaps and chest thrusts.
Rescuers should switch roles after every 5 cycles of CPR.
Signs of airway obstruction: poor air exchange, high-pitched noise on inhalation, inability to speak.

CPR Quality and Guidelines

High-quality CPR characteristics: initiate compressions within 10 seconds of cardiac arrest recognition, push hard and fast, and minimize interruptions.
2010 AHA guidelines recommend the BLS sequence: Chest compressions, Airway, Breathing.
Compression to ventilation ratio for lone rescuers: 30:2.

Chain of Survival and AED Use

The adult Chain of Survival does not include advanced airway placement.
Steps for AED operation: power on, attach pads, analyze rhythm, clear patient, and deliver shock.
In adults with an advanced airway during 2-rescuer CPR, provide breaths every 6 to 8 seconds (8 to 10 breaths per minute).

Initial Steps and Pulse Checks

Initial BLS steps for adults: assess the victim, activate EMS, obtain AED, check pulse, start CPR.
Pulse check location for children (1 year to puberty): carotid or femoral artery.
Use child AED pads for those 8 years old or younger.
Adult pulse check should be performed at the carotid artery.

AED Safety

An AED is safe to use when a victim is in snow, has a pacemaker, or has a medication patch; avoid using it if the victim is partially in water.
