What is the target SpO2 range for most patients experiencing acute respiratory distress?

The target SpO2 range for most patients experiencing acute respiratory distress is set at 94-98%. This range is optimal because it ensures adequate oxygenation while minimizing the risk of hyperoxia, which can have detrimental effects, particularly in certain populations, such as those with COPD or other chronic lung conditions. Maintaining oxygen saturation within this range helps to support cellular metabolism and reduce the risk of complications associated with hypoxemia, such as organ dysfunction.

Setting the target above 98% may not be necessary for all patients, as higher levels of oxygen may lead to harmful effects without providing additional benefits. Conversely, a saturation goal below 94% can increase the risk of inadequate tissue oxygenation. Therefore, targeting SpO2 values within the 94-98% range offers a safe and effective strategy for managing patients with acute respiratory distress.
