LLU Comprehensive Hyperbaric Medicine Program's Mission

Treatments and Services

Healing critically ill and non-critically ill patients with Hyperbaric Oxygen (HBO)

The Hyperbaric Medicine Service at Loma Linda University Medical Center is proud to be the regions only comprehensive HBO program that treats critically ill and non-critically ill patients with HBO. 

The flagship of HBO programs in California, our certified HBO trained physicians and certified HBO staff combined have over 35 years of experience.

Our program started in 1981 with one monoplace chamber (accommodates a single patient).  Our program now operates four monoplace chambers with the ability to perform emergent critically ill HBO treatments 24 hours a day. Our treatment facility also contains an extraordinary chamber that will accommodate a seven-foot patient, weighing up to five hundred pounds. 
All of our chamber cylinders are constructed of clear acrylic, giving the patient a clear view around them thus reducing anxiety related to confinement.  Each chamber is equipped with a flat screen television and DVD player.  During HBO treatments patients can also choose to listen to music or simply sleep during their treatment which usually last approximately two hours.  A specially trained chamber operator is present at all times.

What is Hyperbaric Oxygen (HBO)?

UHMS defines hyperbaric oxygen (HBO) as an intervention in which an individual breathes near 100 percent oxygen intermittently while inside a hyperbaric chamber that is pressurized to greater than sea level pressure (1 atmosphere absolute, or ATA).

What this implies clinically is that pressure must equal or exceed 1.4 ATA while breathing near 100 percent oxygen. The United States Pharmacopoeia (USP) and Compressed Gas Association (CGA) Grade A specify medical grade oxygen to be not less than 99 percent by volume and the National Fire Protection Association specifies USP medical grade oxygen.
