Study Notes
BLS Guidelines and Procedures
- Recommended BLS sequence: Chest compressions, Airway, Breathing (CAB).
- Compression to ventilation ratio for one-rescuer CPR for all ages: 30:2.
- In two-rescuer CPR, rescuers should switch roles after every two cycles.
- Proper steps for using an AED: Power on, attach pads, analyze rhythm, clear the area, deliver shock.
Pulse Check and CPR Techniques
- Pulse check in children (1 year to puberty): Carotid or femoral artery.
- Pulse check in adults: Carotid artery.
- Pulse check duration should be no longer than 10 seconds.
- In infants, check for pulse at the brachial artery.
Special Considerations for Age Groups
- Child AED pads are necessary for children aged 8 or younger.
- Consider an infant as anyone under the age of 1 for BLS purposes.
- For pediatric cardiac arrest, ventilations should be given due to high likelihood of respiratory causes.
Emergency Scenarios
- In the case of a choking adult, the best response is to perform abdominal thrusts.
- If an infant becomes unresponsive after choking, CPR should be initiated immediately.
- If a victim is found unresponsive and not breathing, deliver 2 minutes of CPR before seeking help.
AED and Defibrillation
- An AED cannot be used safely if the victim is lying partially in water.
- Avoid placing AED pads over any abnormalities or bulges in the chest area.
- After delivering a shock, immediately resume CPR.
- If AED advises shock, clear the patient before delivering.
Respiratory Distress
- A child exhibiting gasping breaths but with a pulse rate of 100 should receive 1 breath every 3 to 5 seconds.
- If a patient still has a pulse, the next step in management is to open the airway.
Choking Relief
- Efforts to relieve choking should stop when the obstruction is removed, the victim becomes unresponsive, or the victim begins breathing normally.
Cardiac Arrest Recognition
- Signs of cardiac arrest in a 21-year-old include blue coloration and collapse, likely due to choking.
- Recognition of cardiac arrest in a 49-year-old with known cardiac history calls for immediate AED use and care adjustments based on physical observations (e.g., bulges).
CPR Guidelines
- Recommended compression depth in adults: Between 2 and 2.4 inches (5-6 cm).
- For victims suspected of neck injury, use the jaw thrust method to open the airway.
