1. Why are you asking this?! Hypoxia without symptoms? You would probably be dead by then. Hypoxia is your brain without oxygen- can be caused by a number of things such as choking, drowning, suffocating, cardiac arrest.
2. thats like asking if you can have cold with no symptoms
3. COPD'ers are usually hypoxic. Their disease is chronic. Their respiratory system has adjusted to the low levels of O2. I have been shocked numerous times.... I have drawn ABG's on people who joked around with me the whole time I was drawing the blood. I would run the blood through our ABG machine and would be floored to see how low their level of O2 was.... anyone else with a low O2 level like that would have been knocked out or not breathing.
4. Asymptomatic nocturnal hypoxia is a major predictor of silent cerebrovascular disease in a high-risk but apparently healthy japanese community-dwelling population ....
