CPR Ventilation Confirmation: Signs of Effective Breath Delivery

Real-Time Indicators During CPR

1. Chest rise: Visible with each rescue breath (primary visual cue).
2. Air escape: Feel/hear exhalation from mouth/nose during chest recoil.
3. Tactile feedback: Warm, humid air on cheek near victim's mouth.
4. Bag-valve-mask (BVM) compliance: Bag refills easily; no excessive resistance.

Common Pitfalls & Fixes

• No chest rise: Reposition airway (head tilt–chin lift / jaw thrust), ensure mask seal, check for obstruction.
• Gastric inflation: Slow breaths (1 sec), lower volume (500–600 mL), avoid excessive force.
• Single rescuer: 30:2 compression:ventilation ratio; minimize interruptions.

Advanced Confirmation (If Available)

• End-tidal CO₂ (ETCO₂) >10 mmHg during compressions indicates pulmonary blood flow + ventilation.
• Capnography waveform confirms tracheal tube placement.

High-quality compressions + effective ventilations = best survival chance. Train regularly.
