Spontaneously breathing lung model comparison of work of breathing between automatic tube compensation and pressure support.
INTRODUCTION Automatic tube compensation (ATC), a new ventilation mode that compensates for the work of breathing imposed by endotracheal tube resistance, recently became commercially available. METHODS We conducted a laboratory study with a lung model and a Nellcor Puritan Bennett 840 ventilator to compare ATC and pressure-support ventilation (PSV). A bellows-in-a-box lung model simulated sp...
متن کاملThe effects of pressurization rate on breathing pattern, work of breathing, gas exchange and patient comfort in pressure support ventilation.
The aim of this study was to investigate the effects of different pressurization rates during pressure support ventilation on breathing pattern, work of breathing, gas exchange and patient comfort in patients with acute lung injury. The pressurization rate modifies the initial pressure ramp by changing the initial peak flow rate: the increase in pressurization rate is associated with a decrease...
متن کاملBreathing frequency and pattern are poor predictors of work of breathing in patients receiving pressure support ventilation.
OBJECTIVE To evaluate the relationships between directly measured work of breathing (WOB) and variables of the breathing pattern commonly used at the bedside to infer WOB for intubated, spontaneously breathing patients treated with pressure support ventilation (PSV). DESIGN In vivo measurements of the WOB were obtained on a consecutive series of adults. Breathing frequency (f), tidal volume (...
متن کاملPrediction of extubation outcome: a randomised, controlled trial with automatic tube compensation vs. pressure support ventilation
INTRODUCTION Tolerance of a spontaneous breathing trial is an evidence-based strategy to predict successful weaning from mechanical ventilation. Some patients may not tolerate the trial because of the respiratory load imposed by the endotracheal tube, so varying levels of respiratory support are widely used during the trial. Automatic tube compensation (ATC), specifically developed to overcome ...
متن کاملWork of breathing in adaptive pressure control continuous mandatory ventilation.
BACKGROUND Adaptive pressure control is a mode of mechanical ventilation where inflation pressure is adjusted by the ventilator to achieve a target tidal volume (VT). This means that as patient effort increases, inflation pressure is reduced, which may or may not be clinically appropriate. The purpose of this study was to evaluate the relationship between ventilator work output and patient effo...
