High-Dose Oxygen Therapy and Acute Hypercapnia in Elderly Patients: A Case Series Analysis.
Am J Case Rep
November 2024
Article Synopsis
- Elderly individuals are frequently detected with episodes of low blood oxygen levels (desaturation) in community settings, leading to increased ambulance transfers and high-dose inhaled oxygen therapy (FiO₂ > 50%).
- Current guidelines recommend administering oxygen via non-rebreather masks for low oxygen saturation, but this can cause dangerous levels of carbon dioxide retention (hypercapnia) in some elderly patients without known risk factors.
- A case series highlights three elderly patients who developed acute hypercapnia after receiving high-dose oxygen therapy, indicating that healthcare providers must consider the risk of oxygen-induced CO₂ retention to improve patient outcomes and resource use.
