Visual Assessment for Pressure-time Curve

Status Completed

Clinical Trial Summary

Airway pressure-time (P-t) curve and stress index (SI) assessment have been proposed to guide the mechanical ventilation settings and minimize ventilator-induced lung injury.

Clinical Trial Description

The stress index (SI), which has been proposed to guide the mechanical ventilation settings and minimize ventilator-induced lung injury. It reflects the change of respiratory compliance during inspiration. Value of SI equals to 1 that indicates a constant compliance, whereas values lower and higher than 1 indicate increase and decrease of compliance over inspiratory time, suggesting tidal recruitment and tidal hyperinflation, respectively. Based on the different values of SI showing different shapes, SI of straight curve equals to 1, SI of concave curve lower than 1 and convex curve higher than 1, the investigators speculated that the SI value could be reliably and accurately estimated by visual inspection of the P-t curve. ;
