Plain English Summary
Background and study aims
Hypoxemic respiratory failure is a condition where there is not enough oxygen in the blood but levels of carbon dioxide are close to normal. Non-invasive ventilation is a form of treatment for acute respiratory failure in which a mask is placed covering the face and mouth of the patient to deliver oxygen. The aim of this study is to test a new noninvasive ventilation strategy in order to find out whether this technique is well tolerated by patients.
Who can participate?
Patients aged 18 and over with hypoxemic respiratory failure
What does the study involve?
All participants are treated with noninvasive ventilation using the new strategy and are evaluated during their stay in ICU and follow-up until discharge from hospital.
What are the possible benefits and risks of participating?
The new technique may avoid the need for endotracheal intubation (breathing tube) with a shorter hospital stay and fewer complications. The risks are related to the facial complications that could arise from the use of the mask (lacerations on the face and nose) and gastric distension (bloating of the stomach) due to the effects of the airway pressure.

Condition
De novo hypoxemic respiratory failure (not produced by acute exacerbations of COPD, chronic pulmonary diseases or congestive heart failure)
Intervention
The study consists of subjecting patients to noninvasive ventilation using a new strategy that includes the programming of ventilatory parameters in BiPAP S / T AVAPS mode in order to observe if this technique is well tolerated by the patients. All patients were admitted during the period between 01/12/2010 and 01/01/2014, informed consent was obtained from patients and their surrogates if they were not able to respond by themselves. A total of 70 patients were recruited for this study. All patients were evaluated during their stay in ICU and follow-up until discharge from hospital.

2. Proportion requiring endotracheal intubation (expressed as percentage)
