How long should a fetus be exposed to oxygen daily if it is experiencing oxygen deprivation?

Patient's question:

No

Doctor's answer:

Pregnant women should not inhale oxygen for too long at one time; 10-20 minutes is ideal. It is best to inhale continuously for a week, then take a break of one to two weeks before inhaling again. This can also be adjusted based on individual needs. Wishing you a good pregnancy.
