Summary

Mechanical ventilation is a vital support associated with the treatment of patients with acute respiratory failure and in other indications such as surgery under general anesthesia, coma or shock. Optimization of settings during mechanical ventilation and implementation of protective ventilation help to avoid ventilation-induced injury, ensure adequate oxygenation and maintain adequate carbon dioxide concentration to avoid respiratory acidosis or alkalosis. Similarly, there is also no clear recommendation, to our knowledge, for the initial setting of the respiratory rate. Therefore, initial settings are not always adequate and in the literature the frequency of respiratory acidosis is very high, reaching about half of the patients receiving mechanical ventilation. VentilO, is an application that is available on smart phones. This educational application provides clinicians with initial settings and optimization of these settings based on gender, height, weight, body temperature and patient type. The algorithm used is based on published data regarding ventilatory requirements in different populations and the anatomical and instrumental dead space of patients. The purpose of our study is to: Assess whether ventilatory settings after intensive care unit admission after cardiac surgery are appropriate to compare the ventilatory adjustments made by clinicians with those proposed by the VentilO application.

Type	Name	Description
OTHER	VentilO application	This educational application provides clinicians with combinations of tidal volume and respiratory rate based on gender, height, weight, body temperature and patient type. The algorithm used is based on published data regarding ventilatory requirements in different populations (i.e. from intubated patients for scheduled surgery to the most severe ICU patients) and anatomical and instrumental dead space. The objective of this application is to help implement personalized protective ventilation in intubated patients according to their characteristics. After patient data entry in the VentilO application, the investigators will compare the recommended settings (for mechanical ventilation) vs the real clinician settings done by clinician after patient admission in ICU after cardiac surgery. The investigators will evaluated the potential effect of the VentilO recommendation on the first arterial (or capillary) blood gases compared to the real settings.
