What is the target SpO2 level for COPD and asthma patients?

In the management of patients with Chronic Obstructive Pulmonary Disease (COPD) and asthma, maintaining an appropriate oxygen saturation level is critical for ensuring adequate oxygenation while minimizing the risk of hyperoxia. The target SpO2 level for these patients is generally set at around 90%.

This target is chosen because, for individuals with COPD, there is a risk of hypoventilation if oxygen levels are raised too high, as they may rely on low oxygen levels to stimulate their drive to breathe. Consequently, aiming for a SpO2 of 90% helps to optimize oxygenation without further suppressing their respiratory drive.

Similarly, for asthma patients, aiming for an SpO2 level of 90% ensures that they are adequately oxygenated without the risk of exacerbating their condition. It balances the need for oxygenation while avoiding potential complications associated with excessive oxygen administration.

In summary, the selection of 90% as the target SpO2 level strikes a crucial balance for the management of both COPD and asthma patients, as it supports effective treatment protocols while safeguarding against the risks associated with high oxygen levels.
