简要总结
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.

结局指标
主要结局
acid-base abnormalities on arterial blood gases
时间窗: On the first result available of arterial blood gases after intensive care unit admission; 1 hour maximum after intensive care admission
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)
次要结局
- hemodynamic instabilities(Between Hour0 to Hour1 after intensive care unit admission)
- Acute renal failure(up to 90 days. ICU stay - ICU admission through ICU discharge or until death if occured)
- Severity of unbalance of arterial blood gases result(On the first result available of arterial blood gases after intensive care unit admission; 1 hour maximum after intensive care admission)
- Mechanical Ventilation duration(up to 90 days. ICU stay - ICU admission through ICU discharge or until death if occured)
- Hospital length of stay(up to 90 days. ICU stay - ICU admission through ICU discharge or until death if occured)
- Occurence of optimal arterial blood gases result(On the first result available of arterial blood gases after intensive care unit admission; 1 hour maximum after intensive care admission)
- ICU length of stay(up to 90 days. ICU stay - ICU admission through ICU discharge or until death if occured)
- ICU mortality(up to 90 days. ICU admission through until death if occured)
