What is the recommended SpO2 for patients maintaining prophylactic hypoxaemia?

In the context of managing patients who are requiring prophylactic hypoxaemia—essentially a controlled level of low oxygen saturation for therapeutic reasons—the recommended SpO2 range is 85-88%. This specific range is chosen because it balances the need to keep oxygen saturation low for certain medical conditions while still ensuring that the patient remains within a safe threshold to avoid potential tissue hypoxia and related complications.

Maintaining an SpO2 level within this range helps to manage underlying conditions effectively without causing harm, as levels lower than this can start leading to significant physiological stress, impairment of vital organ function, and increased risk of adverse outcomes. The guidance emphasizes careful monitoring and individualized assessment, ensuring that while the patient is under treatment strategies such as oxygen therapy or ventilation management, their safety and physiological needs are prioritized.

Other ranges outside this recommended level could lead either to inadequate oxygenation or unnecessary risks of hypoxic damage, thus reinforcing the importance of adherence to this specific SpO2 target for the stated patient group.
