I'm really worried about my grandfather who was just admitted to the ICU after having a cerebral stroke. Now he's got pneumonia, and I noticed the doctor reduced his oxygen cylinder level from 8 to 5. Ever since, his SpO2 has been around 85. I'm trying to understand why the doctor would lower his oxygen like that, especially when his condition doesn't seem to be getting better. What could be the reason for this decision?

Oxygen Level Adjustment

• Oxygen levels might be lowered to prevent complications like oxygen toxicity or to manage carbon dioxide retention, especially in elderly patients with compromised lung function.

Specific Considerations for Your Grandfather

• Reducing oxygen can help avoid high carbon dioxide levels, which can occur if the body retains too much CO2 due to excessive oxygen.

Monitoring SpO2

• It's crucial to keep SpO2 within a safe range. An SpO2 of 85% is low, and adjustments may be needed to improve it.

Next Steps

• Discuss with the ICU team to understand the specific reasons for the adjustment and ensure your grandfather receives optimal care.
