Does lung cancer affect SpO2?

The presence of high carboxyhemoglobin values in heavy smokers could disturb the SpO2 reading by the pulse oximeter [22].

Low oxygen saturation is a common finding in patients with terminal cancer [1,2,3] and thus supplemental oxygen is frequently provided to patients with terminal cancer [4].

What is oxygen level if you have lung cancer?

What is the lowest oxygen level you can live with?

Anything between 92% and 88%, is still considered safe and average for someone with moderate to severe COPD. Below 88% becomes dangerous, and when it dips to 84% or below, it’s time to go to the hospital. Around 80% and lower is dangerous for your vital organs, so you should be treated right away.
