【Haichuan Teahouse】Is there a large oxygen tank connected to the oxygen mask in an airplane cabin?
Thread Content
We often see thrilling scenes in movies where, as an airplane descends, the passengers’ oxygen masks fall off automatically and an emergency alert about cabin depressurization is issued. At such times, one might wonder whether there is a large oxygen tank connected to each oxygen mask
I think there should be a large oxygen tank
It needs to be replenished in the event of pressure loss; one blower should be sufficient
It should be oxygen-enriched positive-pressure air, a combination of an oxygen tank and an air compressor. Similar to the pressure at high altitudes, the atmospheric pressure in Tibet is over 600 hPa (while it’s around 1000 hPa in the plains). With a normal breathing rate, the amount of oxygen that can be inhaled is only 60-70% of the normal level
It is estimated that liquid oxygen and dry ice are available, and they are delivered in proportion.

If there’s a problem with liquid oxygen, then dry ice can help reduce the discomfort for passengers on the plane, right?
