Is the air from a CPAP machine same as oxygen?

No, the air from a CPAP machine is not the same as oxygen.

A CPAP (continuous positive airway pressure) machine is a medical device used to treat sleep apnea. It works by delivering pressurized air to the user's airway through a mask, which helps to keep the airway open and prevent it from collapsing during sleep. The air from a CPAP machine is simply room air that has been pressurized, and does not contain any additional oxygen.

Oxygen therapy, on the other hand, is a medical treatment that involves delivering supplemental oxygen to a patient through a nasal cannula or mask. This is used to treat conditions where the body is not able to get enough oxygen on its own, such as chronic obstructive pulmonary disease (COPD) or pneumonia. Oxygen therapy uses medical-grade oxygen, which is a highly concentrated form of oxygen that is typically 95% pure or higher.

Therefore, the air from a CPAP machine is not the same as oxygen. CPAP machines deliver pressurized room air, while oxygen therapy delivers supplemental medical-grade oxygen.
