I am fine.
Yesterday, Teck Ann helped me to return the oxygen concentrator machine to the supplier. I have rented for three months. The rental is about RM300 per month. It help to ease the breathless situation. My current SP02 is 92%, normal >95%.
It delivered continuous flow of process ambient air at various liter per minute with an associated percentage oxygen. Example, at 0 liter per minute (room air ), 21% oxygen. At 3 liter per minute, 33% oxygen.
