Oxygen equipment
On the advice of fellow club members I ordered an oxygen-saving cannula,
flow meter, and connector to use O2 in a club ship. When I placed the order I was advised by the vendor that regulations require a MASK in the ship, not just a cannula. He mentioned some situations wherein a mask would be better, e.g. if one has a head cold, if one is panicking and breathing through the mouth, etc. Makes sense, but that doesn't mean it's required by the FAA. I looked it up in FAR/AIM, but I'm not finding a CFR that requires a mask in an unpressurized aircraft. 91.211(b)(ii) does, but it's for pressurized cabin aircraft. I haven't bought a mask bit I might if it's wise or required. Seems to me that to switch from cannula to mask you'd either need a Y and shutoff valves, or quick-connects. Comments? Advice? |

It's very important to remember to breathe through your nose. My older
nose doesn't always stay open and I frequently find myself breathing through my mouth. I added a little plastic band with 2 holes in it, to the nasial tubes so that they are spread out a bit. Works great. Don't forget to gently blow back into these tubes when pre-flighting your oxygen equipment, should get resistance, easy flow means one of the little bladders is ruptured. These things are only good for 200 hours of use, so about every 4 years, through it away and buy a new one. Nelson says it's good up to 18K, above that he recommends a mask, believe the Feds agree.
