Implication

Experimental validation of a new algorithm detects respiratory phases in intra-arrest ventilation, indicating high accuracy for clinical use.

Key Points

  • The research aims to create a method for detecting respiratory phases during intra-arrest ventilation amidst chest compressions.
  • Developed an algorithm based on airflow and airway pressure products.
  • Used ventilatory recordings from 13 pigs under mechanical ventilation for validation.
  • Selected 20 ventilations before cardiac arrest and 20 during ongoing chest compressions for analysis.
  • Compared algorithm performance against expert-validated respiratory phase onsets.
  • Achieved perfect classification of inspiratory and expiratory phases in regular ventilation.
  • F1-score of 1 during regular ventilation and 0.971 during intra-arrest ventilation.
  • Successfully differentiated between artificial ventilations and airflow from chest compressions.
