What is the target oxygen saturation level (O2 target) for patients with ARDS?

The target oxygen saturation level for patients with Acute Respiratory Distress Syndrome (ARDS) is established in order to optimize oxygen delivery while minimizing potential harm from excessive oxygen exposure. A target range of 88-95% is generally recommended, as this level helps ensure adequate oxygenation without significantly increasing the risk of oxygen toxicity or other adverse effects associated with hyperoxia.

Maintaining oxygen saturation within this range allows clinicians to balance providing sufficient oxygen to meet the metabolic needs of tissues while avoiding complications that may arise from elevated oxygen levels, especially considering the vulnerability of patients with ARDS. This target is often determined based on guidelines from respiratory and critical care organizations, which advocate for individualized approaches based on each patient's condition and response to therapy.

Given this context, the choice of 88-95% is appropriate because it reflects current clinical practices and evidence-based guidelines aimed at treating patients with ARDS effectively and safely.
