Sechrist H-Series is a monoplace hyperbaric oxygen chamber.
INTENDED USES: Provides the ability for the patient to rest in a reclined or angled position for better comfort. Provides for easy loading of the patient into the chamber without additional transfers.
CLAIMED FEATURES: With the new space-saving gurney storage, hospitals and clinics now have the ability to store the gurney under the hyperbaric chamber. Additional storage allows for more free space in the hyperbaric treatment room, thus eliminating any extra needed space to store free standing chamber gurneys. The low profile gurney lowers to 23 inches from the floor to the top of mattress, thus eliminating a full 5 inches off the height of a standard hyperbaric chamber gurney. The new low profile design allows you to safely and easily move patients to and from the gurney.
OPTIONS: Available in three interior diameters – 33″, 36″, and the 41″.

3600H Chamber Overview


Assuring safety

Sechrist Hyperbaric Oxygen Chambers are designed and tested to provide the most complete safety specific monoplace hyperbaric chamber on the market. All Sechrist hyperbaric chambers go through a thorough inspection and safety process that is monitored and maintained throughout the manufacturing process. Sechrist hyperbaric oxygen chambers are the only monoplace hyperbaric chambers that are fully manufactured and tested in the USA in our state-of-the-art facility. 
The H-Series Hyperbaric Oxygen Chambers is the only monoplace hyperbaric system that provides two emergency vent modes. The Standard Emergency Vent system decompresses in less than 120 seconds, and can be controlled by a technician to allow control of the descent and to optimize for patient comfort. The H-Series Hyperbaric System also includes an Emergency Shut-off and Automatic Vent System for full decompression within 120 seconds without the need of an attendant.

Increasing efficiency

The Sechrist H-Series hyperbaric oxygen chambers are all equiped with the necessary monitors and controls to accept electronic data collection modules. With precision controls and easy viewing displays the Sechist H-Series Hyperbaric Chambers are easy to use and adjust by the attending pysician or technician. All Sechrist oxygen chambers have easily accessible ventilation controls for the adjustment of gas flow through the chamber for complete oxygen conservation. Sechrist’ s Oxygen Conservation Mode significantly reduces the amount of oxygen consumed during a treatment.

Supporting critical care

The Sechrist H-Series Hyperbaric Chamber also provides for respiratory support that automatically compensates for the pressure changes in the chamber using Sechrist’ s customized hyperbaric ventilator. The Sechrist Hyperbaric Ventilator is designed and manufactured by Sechrist and is the only true hyperbaric ventilator on the market for Sechrist chambers. The Sechrist H-Series Hyperbaric Chamber also accommodates multiple connection types for full support of a patients critical needs:
  • Multiple intravenous transfusion lines.
  • Electrical monitoring including EKG, temperature and blood pressure.
  • Transcutaneous oxygen monitoring.
  • Patient air-break breathing system.


Evidence-based indications accepted by the UHMS, approved by Medicare

Elective – Chronic Indications
Emergent/Urgent – Acute Indications

Evidence-based indications accepted by the UHMS, NOT approved by Medicare

Elective – Chronic Indications
Emergent/Urgent – Acute Indications


The only absolute contraindication to hyperbaric oxygen therapy is an untreated pneumothorax due to the risk of gas emboli, tension pneumothorax and pneumomediastinum

The following contraindications are relative but should be carefully considered when weighing the risk benefit ratio for HBO. [1]

  • Bleomycin- The primary dose-limiting toxicity of bleomycin is the development of pulmonary toxicity ranging from radiographic changes to pneumonitis to fatal pulmonary fibrosis. Despite the theoretical risk, no documented cases of bleomycin pulmonary toxicity from hyperbaric oxygen exist. It is felt that as long as the patient has no signs of pulmonary compromise from fibrosis, and it has been over three months since he or she was treated with bleomycin, his or her exposure to bleomycin should not be a health factor. 
  • Doxirubicin- An anteneoplastic agent that exerts its effect through generation of free radicals and has a dose-limiting cardiac toxicity as a consequence of therapy. HBOT and doxorubicin should be avoided in combination. It is recommended that at least three days to elapse between the last doxirubicin dose and the initiation of a course of HBOT.
  • Cisplatin- A chemotherapeutic that interferes with the DNA synthesis, affecting fibroblast production and collagen synthesis. HBOT may impede wound healing in combination with cisplatin. Any patient who has a wound healing problem should not be treated concomitantly. However, in life threatening situations such as CO poisoning, gas gangrene and necrotizing fasciitis, wound healing concerns are overridden by the emergency indication.
  • Disulfiram- A theoretical risk with using disulfiram in the chamber is that it, or its reduced metabolite diethyldithiocarbamate, blocks the production of superoxide dismutase (SOD), a major protective enzyme against oxygen toxicity.
  • Mafenide Acetate (Sulfamylon)- An antimicrobial agent used in burn patients is a carbonic anhydrase inhibitor and tends to promote CO2 retention and vasodilation which can lower the seizure threshold. 
  • Upper Respiratory Infections or Chronic Sinusitis- May pose the inability to equalize middle-ear pressure
  • Emphysema with C02 retention or Asthma- These obstructive diseases can reduce the outflow of gas during decompression leading to pulmonary barotrauma.

Risks and Complications

Risk benefit ratio in favor of offering hyperbaric oxygen therapy, example statement:   

 "The patient was informed of the possible risks and complications of hyperbaric oxygen therapy. These include, but are not limited to, fire, barotrauma of the ears, sinuses, and lungs to include air embolism, central nervous system oxygen toxicity resulting in seizure, cataracts, myopia, and exacerbation of congestive heart failure. Having no absolute contraindication to hyperbaric oxygen therapy the patient will be offered treatment at 2.0 ATA for 90 minutes. Twenty treatments will initially be provided on a once daily basis Monday through Friday. Thereafter, a re-evaluation of the patient’s clinical progress will be in order to determine if additional treatments may be required."


Sechrist hyperbaric chambers have been cleared by the FDA 510K .

Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Dmg, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRI-1 does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading. 


• A Physician order is required for the delivery of Hyperbaric Oxygen therapy and must include:

- Hyperbaric diagnosis and Treatment protocol.

- Specific pre-HBOT diagnostics necessary

- Treatment Pressure (depth) and oxygen breathing period (dive profile that is to be used)

- Air breaks – when indicated or per treatment protocol

- TCOM’s (as appropriate to patient condition)

- Total treatments.

• At a minimum, the following elements should be provided on the physician order form as well:

- The date of the order

- The patients name, date of birth and medical record/account number.

- The name of physician or authorized individual ordering hyperbaric oxygen services.

- Authentication of physician or authorized individual ordering hyperbaric oxygen services.
