Automatic oxygen administration and weaning in patients following mechanical ventilation.

Purpose: To evaluate efficacy of FreeO2 device in oxygen weaning of patients after being liberated from mechanical ventilation (MV).

Methods: Prospective crossover cohort study in patients admitted to ICU and after MV weaning. FreeO2 curves were recorded during constant flow and FreeO2 modes.

Noninvasive ventilation with helium-oxygen mixture in hypercapnic COPD exacerbation: aggregate meta-analysis of randomized controlled trials.

When used as a driving gas during NIV in hypercapnic COPD exacerbation, a helium-oxygen (He/O) mixture reduces the work of breathing and gas trapping. The potential for He/O to reduce the rate of NIV failure leading to intubation and invasive mechanical ventilation has been evaluated in several RCTs. The goal of this meta-analysis is to assess the effect of NIV driven by He/O compared to air/O on patient-centered outcomes in hypercapnic COPD exacerbation.
