Diaphragmatic Echography in COVID-19 Pneumonia

Prognostic Value of Transthoracic Diaphragmatic Echography in COVID-19 Pneumonia Patients With Acute Respiratory Failure

We hypothesized that diaphragm thickness is concerned in acute respiratory failure of COVID19 patients and its ultrasound measure at the begining of hospitalisation is a good predictor of poor outcome.

A prospective observational non intervention study is designed.

To answer our hypothesis we will perform diaphragm ultrasound in the first 24hr hospitalized COVID19 patients.

In the ultrasound exploration we will assess diaphragm movility and thickness. We will also assess other clinical, biochemistry and radiological variables. The main outcome we want to analyze is the destination on discharge: home, respiratory intermediate critical unit or exitus.

Inclusion Criteria:

• COVID19 Pneumonia Acute respiratory failure (PaO2 <60mmHg)

Exclusion Criteria:

• Invasive or non invasive ventilation within first 24h Neuromuscular disease Diaphragmatic paralysis
