I went for surgery clearance and my cpap report was at 67% 4hrs+ every night for 30 days. They said I need to be at 70% to be cleared for surgery. Does anyone know why this is? I do wear it consistently but do not sleep very well. I have mild sleep apnea and this seems so trivial to me to keep me from surgery. Can anyone explain their reasoning? Thank you!

I think it’s about ensuring your blood is well oxygenated & also poor breathing and sleep affects your heart & blood pressure. But most importantly, sleep apnea puts you at higher risk with anaesthesia which slows your already compromised breathing resulting in complications during & immediately after surgery.

Certainly worth a conversation with your surgeon & maybe your respiratory doctor as well.

All of the reasons above plus the heightened risk of lung collapse due to the surgery. I found that when my cpap readings fell short, it was mostly due to my mask not being tight enough for a proper seal. The stronger my oxygen levels, the better I started sleeping. Keeping fingers crossed for you!!
