She either is getting supplemental oxygen, or has an oxygen concentrator
She is so big that she cannot take a normal breath.
Bet she has mild respiratory acidosis
,CO2 level and pH are elevated and O2 level is hanging around 88-90, and Bicarbonate is elevated as well
Nothing like having COPD at her age.
Wonder if she gets Pickwickian Syndrome when she lays flat(?)yu
Not a good way to live.
She's using an oxygen concentrator; it's on the seat next to her.
One of my family members has lung damage due to industrial lung injury, and uses a similar device.
