Assessing the safety and feasibility of upright positioning for patients with acute respiratory distress syndrome.

Official title: Early Verticalization of the Patient With Acute Respiratory Distress Syndrome: Assessment of Feasibility and Safety.

This study is testing if sitting patients up at an angle can help those with Acute Respiratory Distress Syndrome breathe better and avoid complications compared to lying flat.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 years old with ARDS and a PaO2/FiO2 ratio of less than 150.

Probably not a fit

Patients who are pregnant, breastfeeding, or have contraindications to standing will not benefit from this study.

What this trial studies

This clinical trial evaluates the feasibility and safety of a new positioning technique called verticalization for patients suffering from Acute Respiratory Distress Syndrome (ARDS). The study involves a cross-over design where patients will alternate between the traditional prone position and the new verticalization technique, which involves gradually raising the patient's bed to a 55° angle. The trial will monitor various clinical responses, including arterial blood gas measurements and chest ultrasounds, to assess the impact of these positioning techniques on patient outcomes. The goal is to determine if verticalization can improve oxygenation and reduce complications associated with the prone position.

Why it matters

Potential benefit: If successful, this approach could enhance patient recovery and reduce complications in ARDS management.

How similar studies have gone: While the prone position has been widely studied and shown to decrease mortality in ARDS, the specific approach of verticalization is novel and has not been extensively tested.
