Recognizing key signs of cardiac arrest or respiratory failure in a victim is crucial for initiating prompt and effective interventions, particularly in the context of Basic Life Support (BLS). The key signs indicating these life-threatening conditions include:
1. Loss of Responsiveness:
- A victim experiencing cardiac arrest or respiratory failure may become unresponsive and show no reaction to external stimuli.
- Lack of responsiveness is a critical indicator that immediate action is required.
2. Abnormal or Absent Breathing:
