Pressure support ventilation + sigh in acute hypoxemic respiratory failure patients: Study protocol for a pilot randomized controlled trial, the PROT…

2018

Background Adding cyclic short sustained inflations (sigh) to assisted ventilation yields optimizes lung recruitment, decreases heterogeneity and reduces inspiratory effort in patients with acute hypoxemic respiratory failure (AHRF). These findings suggest that adding sigh to pressure support ventilation (PSV) might decrease the risk of lung injury, shorten weaning and improve clinical outcomes. Thus, we conceived a pilot trial to test the feasibility of adding sigh to PSV (the PROTECTION study). Methods PROTECTION is an international randomized controlled trial that will be conducted in 23 intensive care units (ICUs). Patients with AHRF who have been intubated from 24 h to 7 days and under…

Pathophysiology of Obstructive Sleep Apnea (OSA)

2021

Obstructive sleep apnea (OSA) is a complex disorder characterized by total or partial collapse of the upper airways (UA) during sleep, causing obstructive apneas or hypopneas, respectively. During respiratory events, respiratory efforts occur against the restricted or collapsed upper airway, hypoxia and hypercapnia develop, and sympathetic activation increases. The main symptoms of OSA are intermittent snoring and excessive daytime sleepiness. OSA is often associated with obesity, hypertension, and increased cardiovascular risk. Pathophysiological aspects include: anatomical and physiological determinants of UA closure, and immediate and long-term consequences of chronic intermittent hypoxi…
