Transthoracic impedance (TTI) effectively captured gasping-related thoracic volume changes, enhancing early cardiac arrest recognition and promoting faster CPR initiation.
Can continuous transthoracic impedance (TTI) monitoring detect gasping to aid in early cardiac arrest recognition?
Transthoracic impedance measured through standard defibrillator pads can detect gasping, offering a potential automated method to improve early cardiac arrest recognition.
Absolute Event Rate: 0% vs 0%
Timely recognition of cardiac arrest (CA) is often delayed because gasping, a frequent sign of CA, is misinterpreted as normal breathing. In a porcine model of untreated CA with frequent gasps, we tested whether transthoracic impedance (TTI), continuously measured through defibrillator pads, could capture gasping-related thoracic volume changes. Gasping-induced inspiratory efforts produced large, distinctive TTI fluctuations. This observation was then confirmed in a healthy human volunteer simulating gasping under open and closed airway conditions. These translational findings support automated, TTI-based gasping detection via automated external defibrillators as a feasible strategy to improve early CA recognition and accelerate bystander CPR initiation.
