What is a potential impact of ECMO on lung function?

The choice indicating that ECMO allows for lung rest and healing is rooted in the fundamental purpose of this therapy. During ECMO, the device takes over the role of oxygenating the blood and removing carbon dioxide, which alleviates the workload on the lungs. This reduction in mechanical ventilation support enables the lungs to recover from a variety of conditions that impair their function, such as pneumonia, acute respiratory distress syndrome, or other forms of acute lung injury.

By offloading gas exchange to the ECMO system, clinicians can minimize ventilator settings, reduce barotrauma and volutrauma, and thus provide the opportunity for the lung tissue to heal. This strategy is crucial in managing patients with severe respiratory failure where lung protection strategies are paramount.

In contrast, the other options suggest negative outcomes or misconceptions about ECMO's effects on lung function. While ECMO is an intervention used in severely ill patients, it is not inherently linked to causing acute respiratory distress syndrome, nor does it usually worsen lung function. Additionally, monitoring lung pressures remains vital to assess the overall condition of the patient and to guide treatment decisions; ECMO does not eliminate the need for this important monitoring.
