an example of mild portable hyperbaric chamber. 40-inch-diameter (1,000 mm) chamber 1 of larger chambers available home.

there several sizes of portable chambers, used home treatment. these referred mild personal hyperbaric chambers , reference lower pressure (compared hard chambers) of soft-sided chambers. food , drug administration (fda) approved chambers use room air available in usa , may go 4.4 pounds per square inch (psi) above atmospheric pressure, equals 1.3 atmospheres absolute (ata), equivalent depth of 10 feet of sea water.

in us, these mild personal hyperbaric chambers categorized fda class ii medical devices , requires prescription in order purchase 1 or take treatments. personal hyperbaric chambers fda approved reach 1.3 ata. while hyperbaric chamber distributors , manufacturers cannot supply chamber in form of elevated oxygen delivery system, physician can write prescription combine 2 modalities, long there prescription both hyperbarics , oxygen. common option (but not approved fda) patients choose acquire oxygen concentrator typically delivers 85–96% oxygen breathing gas.

because of high circulation of air through chamber, total concentration of oxygen in chamber never exceeds 25% can increase risk of fire. oxygen never fed directly soft chambers rather introduced via line , mask directly patient. fda approved oxygen concentrators human consumption in confined areas used hbot regularly monitored purity (+/- 1%) , flow (10 15 liters per minute outflow pressure). audible alarm sound if purity ever drops below 80%. personal hyperbaric chambers use 120 volt or 220 volt outlets. ranging in size 21 inches 40 inches in diameter these chambers measure between 84 in (7 ft) 120 in (10 ft) in length.

the soft chambers approved fda treatment of altitude sickness, commonly used other off-label purposes.
