Effect of inspiratory synchronization during pressure-controlled ventilation on lung distension and inspiratory effort.

ABSTRACT:

Background

In pressure-controlled (PC) ventilation, tidal volume (V _T) and transpulmonary pressure (P _L ) result from the addition of ventilator pressure and the patient's inspiratory effort. PC modes can be classified into fully, partially, and non-synchronized modes, and the degree of synchronization may result in different V _T and P _L despite identical ventilator settings. This study assessed the effects of three PC modes on V _T, P _L , inspiratory effort (esophageal pressure-time product, PTP_es), and airway occlusion pressure, P _0.1. We also assessed whether P _0.1 can be used for evaluating patient effort.
