Oxygen therapy and noninvasive respiratory supports in acute hypoxemic respiratory failure: a narrative review.

Background: This narrative review was written by an expert panel to the members of the jury to help in the development of clinical practice guidelines on oxygen therapy.

Results: According to the expert panel, acute hypoxemic respiratory failure was defined as PaO < 60 mm Hg or SpO < 90% on room air, or PaO/FiO ≤ 300 mm Hg. Supplemental oxygen should be administered according to the monitoring of SpO, with the aim at maintaining SpO above 92% and below 98%.

Impact of inhaled sedation on delirium incidence and neurological outcome after cardiac arrest - A propensity-matched control study (Isocare).

Rationale: Poor neurological outcome is common following a cardiac arrest. The use of volatile anesthetic agents has been proposed during post-resuscitation to improve outcome.

Objectives: To determine the effects of inhaled isoflurane on neurological outcome, delirium incidence, ICU length-of-stay, ventilation duration, mortality during post-resuscitation care of ICU patients.

Defining predictors for successful mechanical ventilation weaning, using a data-mining process and artificial intelligence.

Mechanical ventilation weaning within intensive care units (ICU) is a difficult process, while crucial when considering its impact on morbidity and mortality. Failed extubation and prolonged mechanical ventilation both carry a significant risk of adverse events. We aimed to determine predictive factors of extubation success using data-mining and artificial intelligence.

Automated Oxygen Titration During CPAP and Noninvasive Ventilation in Healthy Subjects With Induced Hypoxemia.

Background: Automated oxygen titration to maintain a stable S has been developed for spontaneously breathing patients but has not been evaluated during CPAP and noninvasive ventilation (NIV).

Methods: We performed a randomized controlled crossover, double-blind study on 10 healthy subjects with induced hypoxemia during 3 situations: spontaneous breathing with oxygen support, CPAP (5 cm HO), and NIV (7/3 cm HO). We conducted in random order 3 dynamic hypoxic challenges of 5 min (F 0.

Elevations of Extracellular Vesicles and Inflammatory Biomarkers in Closed Circuit SCUBA Divers.

Blood-borne extracellular vesicles and inflammatory mediators were evaluated in divers using a closed circuit rebreathing apparatus and custom-mixed gases to diminish some diving risks. "Deep" divers ( = 8) dove once to mean (±SD) 102.5 ± 1.
