Is this a) auto-triggering, b) an ineffective effort, c) early cycling, or d) double triggering?

(1) No drop in airway pressure

Answer: Auto-triggering

The ventilator is triggered in the absence of an inspiratory effort by the patient.

How to recognize it:

Look for a delivered mechanical breath showing no drop in airway pressure (1) at the beginning of the inspiratory phase. This is because the patient does not make an active inspiratory effort. Did you know that over 60% of health care professionals surveyed found it difficult to recognize and treat asynchronies in adult and pediatric patients?1. See the list of possible causes and solutions below.

Common possible causes:

  • Trigger threshold set too low
  • Air leaks in the endotracheal tube cuff, ventilator circuit, or chest tube
  • Flow oscillations (water or secretion in the circuit, cardiac oscillations)

Solution:

Increase the inspiratory trigger setting in order to avoid oscillations (if not heart-associated) and leaks.
