Adult Basic Life Support (BLS) is a set of emergency procedures performed to maintain life in cases of cardiac arrest or respiratory distress. Here’s a summary of its key components:
1. Assessment
– Scene Safety: Ensure the environment is safe for both the rescuer and the victim.
– Check Responsiveness: Tap the person and shout, “Are you okay?”
– Call for Help: If unresponsive, call emergency services or ask someone else to do so.
2. Airway Management
– Open the Airway: Use the head-tilt, chin-lift maneuver unless a spinal injury is suspected. In that case, use the jaw-thrust maneuver.
– Check for Breathing: Look, listen, and feel for breathing for no more than 10 seconds.
3. Breathing Support
– Rescue Breaths: If the person is not breathing or only gasping, give 2 rescue breaths:
– Pinch the nose, seal your lips around their mouth, and give breaths lasting about 1 second each, ensuring the chest rises visibly.
– Continue to Assess: After 2 rescue breaths, check for pulse and breathing again.
4. Circulation Management (CPR)
– Chest Compressions: If there is no pulse:
– Place the heel of one hand on the center of the chest (lower half of the sternum) and the other hand on top. Interlock fingers.
– Compress at a depth of at least 2 inches (5 cm) at a rate of 100-120 compressions per minute.
– Allow full chest recoil between compressions.
– Compression-to-Ventilation Ratio:
– For adults: 30 compressions followed by 2 rescue breaths.
5. Defibrillation
– Automated External Defibrillator (AED): If available:
– Turn on the AED and follow voice prompts.
– Ensure no one is touching the victim during the analysis and shock delivery.
– Continue CPR after shock delivery until emergency services arrive.
6. Continue Care
– Keep providing high-quality CPR until emergency medical services (EMS) arrive, the person shows signs of recovery (e.g., starts breathing), or you are too exhausted to continue.
Key Considerations
– Teamwork: In a team setting, rotate roles every 2 minutes to prevent fatigue.
– Post-Resuscitation Care: Once EMS takes over, provide them with information about the incident and interventions performed.
