Airway Occlusion Pressure and P0.1 to Estimate Inspiratory Effort and Respiratory Drive in Ventilated Children.

ABSTRACT:

Objective

To compare the level of agreement between proximal (near the subject) and distal (inside the ventilator) measured airway occlusion pressure at 100 ms (P0.1) and occlusion pressure (Δ Pocc ), and to study the correlation between Δ Pocc and peak-to-trough esophageal pressure (Δ Pes ).

Design

Secondary analysis of prospectively collected physiology dataset (2021-2022).

Setting

Medical-surgical 20-bed PICU.

Patients

Children younger than 18 years with and without acute lung injury ventilated greater than 24 hours and spontaneously breathing with appropriate triggering of the ventilator.

Interventions

None.

Measurements and main results

Data from three expiratory hold maneuvers (with a maximum of three breaths during each maneuver) in 74 subj
