A 56-year-old female asked about a 81-year-old male:
what would cause my dads oxygen levels when they get it up from 75 to 90 to pass out?

Possibly he is: Retaining co2. If your dad has COPD and has been given a lot of supplemental oxygen in an effort to increase his oxygen saturation (spo2) he may not have enough respiratory drive to blow off the co2 independently and develop co2 narcosis causing him to be unresponsive. In these patients, we often use non-invasive positive pressure (bi-pap) to help patients as an alternative to mechanical vent.

How do I use oxygen at home?

As much as possible: While some recommendations call for nighttime use of oxygen only, the life prolonging effect of oxygen use for COPD comes from 24/7 use. Nighttime use does give some symptoms relief, but it's mainly for convenience.

What is micturital syncope?

Vagus Nerve: In order to emply one's bladder, one has to tighten up the abdominal muscles to increase the pressure surrounding the bladder. This process results in increased stimulation of the vagus nerve or tenth cranial nerve, which incidentally slows the heart rate. Sudden drops in the heart rate and blood pressure then cause susceptible people to pass out or have syncope.

Is hyperbaric oxygen chambers useful for autism?

Inconclusive: Various news media and nontraditional societies advocate hyperbaric/100% treatment for autism. There are no conclusive studies to support this, although the treatment issued in europe. In the us, huber aric treatment is only approved for the bends, wound healing and carbon monoxide poisoning. The dangers of hyperbaric chamber treatment outweigh the benefits (if any) at this time. Oxygen toxicity.

Why do some people pass out while on a dialysis machine?
2 doctor answers • 5 doctors weighed in
Specializes in Nephrology and Dialysis
Low Blood Pressure: Unfortunately, dialysis is an exchange of blood between the patient and the hemodialysis machine. At certain times, too much blood can be taken from a patient that leads to an acute drop in blood pressure. This decrease in blood pressure likely leads to some people passing out while on the hemo-dilaysis machine.
