Such equipment can withstand repeated use in a patient's home and includes wheelchairs, hospital beds, catheters, nebulizers, iron lungs, and oxygen tents.
Reduced oxygen tents are designed to replicate the effects of living at high altitude, increasing red blood cells and the blood's oxygen-carrying capacity to improve stamina.
Athletes go to altitude or use the low oxygen tents to stimulate the body's production of red blood cells, which then help carry oxygen more efficiently around the body.
