Brief 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:
- 1.Assess whether ventilatory settings after intubation are appropriate.
- 2.To compare the ventilatory adjustments made by clinicians with those proposed by the VentilO appalication.

Outcome Measures
Primary Outcomes (3)
acid-base abnormalities on arterial (or capillary) blood gases
evaluate the frequency of acid-base abnormalities, either acidosis or alkalosis, of respiratory or mixed origin on the first arterial gases after intubation. Respiratory acidosis is defined as a pH \< 7.35 with a PaCO2 \> 45 mmHg, and respiratory alkalosis as a pH \> 7.45 with a PaCO2 \< 35 mmHg)
on the first result available of arterial(or capillary) blood gases after intubation; 2 hours maximum post intubation
Improvement acid-base abnormalities with the VentilO application
* In case of respiratory acidosis: minute ventilation proposed by VentilO \> set minute ventilation; * In case of respiratory alkalosis: proposed minute ventilation by VentilO \< set minute ventilation
on the first result available of arterial(or capillary) blood gases after intubation; 2 hours maximum post intubation
Impairement acid-base abnormalities with the VentilO application
* In case of respiratory acidosis: proposed minute ventilation by VentilO \< set minute ventilation * In case of respiratory alkalosis: minute ventilation proposed by VentilO \> set minute ventilation
on the first result available of arterial(or capillary) blood gases after intubation; 2 hours maximum post intubation
Secondary Outcomes (6)

Study Arms (1)
Intubated patient during their stay in the IUCPQ-UL emergency or intensive care department
Interventions
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 appllication we will compare the recommended settings (for mechanical ventilation) vs the real clinicial settings done by clinician after patient intubation.We will evaluated the potential effect of the VentilO recommendation on the first arterial (or capillary) blood gases compared to the real settings.
