Some information please….

What is the required flow of oxygen using cannulas (is that spelt correctly?) in litres per minute or hour at given density altitudes?

Ie at 16000 feet what should the flow rate be for a single person etc etc.

Thanks

Hope this is of help :)

You could buy yourself an oxymeter, that measures the amount of oxygination in the blood by shining a light through a finger, and seeing how red the blood is.

The Nonin Onyx from Nonin Medical, Inc., in Plymouth, Minnesota. Measures pulse rate and blood oxygenation at around $US400.

This article from Avweb reviews the product, with information like the following:

As we climbed above 14,000 feet, Brent and I donned conserving cannulas and turned on the flow of supplemental oxygen. After leveling at 17,000 feet, we started experimenting with various oxygen flow rates (using a calibrated vernier flowmeter) to determine the impact on oxygen saturation. We found that without supplemental oxygen, O2 sat readings decreased into the mid-70s (extreme impairment), but that saturation could be brought up to a very acceptable level (low 90s, equivalent to a physiological altitude of 6,000 or 8,000 feet) by using an extremely low O2 flow rate (0.5 liter/minute or less). Turning up the flow rate had no significant beneficial effect whatever.
