Oxygen: A low oxygen saturation definitely affects judgment. Your brain is one of the organs that is heavily dependent on proper oxygenation. If you decrease the oxygen saturation, judgment may be impaired.

Depends how low: Down to about 80% there isn't much effect at all at least for short periods of time. Longer periods weeks to months can have cognitive effects. Below 80% saturation there can be clear effects on judgment even for brief periods. The lower the saturation the bigger the effect.

Is hyperbaric oxygen therapy really used to treat autism or behavior disorders?

Dr. Carla Enriquez
Pediatrics 50 years experience
Yes but no evidence: Hyperbaric oxygen therapy is used in europe for behavior problems such as autism, but it is not approved in the us for these purposes because there is no substantive evidence it is beneficial. The studies reported so far where poorly done, and poorly controlled. More research needs to be done to show a benefit.

Could breathing 100% o2 be bad for COPD patients?

3 doctor answers7 doctors weighed in
Dr. Robert Kwok
Pediatrics 33 years experience
Depends on patient: Oxygen in tanks is "100% oxygen", and should be considered a medication. The amount of "100% oxygen" used varies from patient to patient. The oxygen from the tank mixes with air from the environment, so that a patient breathes in somewhat enriched air. Doctors do worry that if a COPD patient gets too much oxygen, he will take fewer breaths per minute, and make his carbon dioxide level go too high.

How does hyperpnea affect the amount of carbon dioxide and oxygen in the blood?

1 doctor answer1 doctor weighed in
Dr. Asaf Presente

Low CO2, alkalemia: Deep or rapid breathing removes more gaseous co2 leading to less co2 in the blood and associated alkalemia - it has a minimal effect on oxygenation except in disease states.
