Which of the following therapies is a rescuer based on evidence for treating ARDS?

The correct answer, Rotaprone, is recognized as a rescuer therapy based on evidence for treating Acute Respiratory Distress Syndrome (ARDS). Rotaprone is a specialized device that facilitates continuous rotation of patients in a prone position. This positioning has been shown to improve oxygenation and reduce mortality in patients with severe ARDS. The prone position helps to redistribute lung perfusion, improve ventilation-perfusion matching, and enhance recruitment of collapsed alveoli, ultimately leading to improved respiratory mechanics and gas exchange.

While antibiotics, fluid resuscitation, and oxygen therapy are important components in the management of ARDS, they do not serve as rescuer therapies in the same way Rotaprone does. Antibiotics may be utilized to address underlying infections that could contribute to ARDS but do not specifically target the respiratory failure itself. Fluid resuscitation is essential for maintaining hemodynamic stability but can also exacerbate pulmonary edema if not carefully managed. Oxygen therapy provides critical support by increasing arterial oxygen levels but does not modify the underlying pathophysiology of ARDS as effectively as Rotaprone therapy. Thus, Rotaprone is distinguished as an intervention that actively addresses the challenging aspects of ARDS management.
