The primary objective is to assess whether the fraction of diaphragmatic shortening in combination with the presence / absence of alveolar-interstitial syndrome evaluated through chest ultrasound may predict successful extubation in adult patients hospitalized in the intensive care unit.
The primary objective is to assess whether the fraction of diaphragmatic shortening in combination with the presence / absence of alveolar-interstitial syndrome evaluated through chest ultrasound may predict successful extubation in adult patients hospitalized in the intensive care unit. The investigators' null hypothesis is the fraction of diaphragmatic shortening in combination with the presence / absence of alveolar-interstitial syndrome evaluated through chest ultrasound can not predict the success of extubation in adult patients hospitalized in the intensive care unit.
The alternative hypothesis is the fraction of diaphragmatic shortening in combination with the presence / absence of alveolar-interstitial syndrome evaluated through chest ultrasound may predict successful extubation in adult patients hospitalized in the intensive care unit.
The study is a no experimental study of diagnostic test, prospective with longitudinal capture. The study will consist of two parts: the first with the aim of finding the values best combination of sensitivity and specificity compared to extubation success for diaphragmatic shortening fraction and the number of lung quadrants with lines B. In the second part the study will make the prospective validation of these values.

| Thoracic ultrasound | Device | The ultrasound will be performed using the ultrasound system GE Logiq XP equipped with a linear probe of 10 MHz. The diaphragm is visualized as two parallel echogenic lines at the eighth intercostal space in the mid-axillary line. The images will be captured during the inspiratory and expiratory tidal volume to and during maximum inspiration and expiration. Each image will be frozen in B mode and the diaphragm thickness will be measured from the center line pleural half the peritoneal line. The fraction of diaphragmatic thickening it is calculated by the formula: diaphragmatic thickness at the end of inspiration - thickness to diaphragmatic at the end of exhalation / diaphragmatic thickness at the end of exhalation x 100. The number of areas with lines B also will be measured. |
| Measure | Description | Time Frame |
|---|---|---|
| Extubation success | The investigators consider successful extubation when the patient does not require reintubation within 72 hours of its extubation | 72 h after extubation |
