Why the sats is 88-92 for copd patients?

In COPD patients, oxygen saturation levels (sats) typically range from 88-92% to ensure adequate oxygen delivery while minimizing the risk of respiratory drive suppression. This range is often considered acceptable because higher saturation levels may lead to carbon dioxide retention, worsening respiratory function. Maintaining sats within this range helps balance the need for oxygen with the body's physiological responses, as many COPD patients have adapted to lower baseline oxygen levels. Thus, individualized management is essential for optimal care.
