1. OxyHelp chambers and accessories

What does the standard price for the OxyLife I hyperbaric oxygen chamber include?

Price includes the OxyLife I chamber and control unit without the AirSep oxygen concentrator or the cooler. The discount applies to accessories as well. The oxygen concentrator with 10L/min has a running price of 1900 Euro.

Monoplace chambers are not delivered in parts. The external diameter has to fit through a doorway as it is. 80 cm chambers require 88 cm door access.

The chamber features standard feeding nozzles on the interior which can connect any type of mask. Find a type you feel comfortable wearing and use it. Please get them locally.

The communication between the operator and patient is done through the stand-alone dual-way intercom placed inside the chamber. The audio-video option is just for entertainment purposes.

The 5 cm extra in the chamber diameter does make a big difference in regards to space. In my experience, Caucasian, European clients require the 80 cm chamber. The 75 cm is mostly sold in Japan.

Yes, pressure control is only limited by software. The higher pressure settings are protected by manufacturer password. Once inserted, the computer allows pressure control settings higher than 1.5 ATA.

The OxyLife I chamber is currently marked and sold as a non-medical device, with a software limitation of 1.5 ATA pressure. OxyHelp chambers are built for 2 ATA max working pressure with automatic controls (computer touch panel). All chambers are built according to PVHO (Pressure Vessels for Human Occupancy) standards (X-Ray, ultrasounds and dye penetrant liquids inspections) by authorized laboratories.

Following the CE certification for Class IIB medical devices, the software upgrade for 2 ATA pressure will be available for 2000 Euro. Consequently, Class IIB certified medical device chambers (same product, current model) will have the price increased by 35%. CE certification for Class IIB medical devices will be available in the near future.

Metal body

OxyHelp metal body soft chambers are popular for home use, the advantage is price and storage space. However, most other soft chambers reach a pressure limited at 1.3 ATA.

OxyHelp medical can go to 2 ATA (3 times the pressure) which covers most of the HBOT protocols and non-medical to 1.5 ATA which has also a big range of HBOT applications. 1.3 ATA is mostly used effectively for neurological issues (brain responds better to lower pressure), all other medical conditions require higher pressure.

Urethane body

Zipper can be damaged sometimes if not being handed carefully. With long time use, the window or zipper will break making the urethane chamber useless. Once the window comes off or zipper teeth weaken, they cannot be repaired without professional help. Especially dangerous when small children are around. They can poke the chamber with something sharp and render it unusable.

2. Operating OxyHelp HBOT chambers

While using this hyperbaric chamber, is it necessary to have any technician or doctor to control?

The user manual for non-medical chamber recommends users to have a medical check-up before using the chamber. Anyone with average studies can operate the chamber as long as reads the user manual. The user manual for medical chamber states that the chamber can be used only with medical consent from a doctor and it requires medical assistance during the treatment.

So a doctor or hyperbaric technician has to be around when operating the chamber. This chamber will be certified as Class IIB medical device according to EEC 93/42. You have to check what regulations in your country say about using a Class IIB medical device.

That is the reason why small practices and private people prefer nonmedical status, while medical facilities want the medical version. In Japan this kind of chambers had been used for 20 years now mostly as nonmedical devices.



Normal speed of slow depressurization is around 8 minutes.

Pressure level and session length can be adjusted anytime, even during session from the touch panel interface on the control unit – outside the chamber. From inside the chamber such changes are not available if the control panel is set exclusively for outside operator control. The possible commands from inside the chamber, without operator control are: start/stop and cooling switch on/off. If the operator sets the control panel to be operated from within, all pressure commands and other features are also available from inside the chamber.

The concentrators can be shut off only from outside the chamber. You can always remove mask and let all O2 inside the chamber. No risk of high levels, even 2 oxygen concentrators are safe. One other thing you could do is to plug the oxygen concentrators in an outlet with remote control and have the remote inside the chamber to power ON/OFF as you wish. Outlets with remote are available in any hardware shop. We can also supply this auxiliary for you.

3. Safety of use

What are the safety features designed control the oxygen/air mix inside the chamber? The tank I had experience with at the medical center (multi-place, and able to do much deeper pressures), is run by staff on the outside who constantly monitor the oxygen/air mix and can flush air into the tank at any time if gases build up. ?

Yes, the multi-place system has the Oxygen level monitor, with an alarm kicking in when Oxygen level drops bellow 19% or increases above 25-26% depending on country regulation.

The standard mono-place pressure vessel doesn’t have this requirement. In Europe it’s OK to use a mono-place air filled chamber without O2 monitor. We only had one client from UK that asked for such monitor, we added it to the chamber for 700 Euro extra.

In practice, though, there is no concern regarding O2 levels, some simple math bellow:

1. Minimum level

Chamber is pressurized with normal air and it is ventilated with 80 liters per min. The 80 cm diameter chamber has a total air volume of 1200 liters at normal air pressure. Human breath is 5-8 liters of air per minute. At this ventilation rate – 80 l/min with 1800 l/ total air volume at 1.5 ATA and 2400 liters at 2 ATA – human body volume around 100 liters, the changes of air composition inside the chamber are insignificant.

(Actually the density of the human body is very close to that of water–that’s why most of us (depending on fat content) sink when we exhale and float when we inhale. Muscle weighs about 1.06 g/ml, and fat is .9 g/ml. And we are made mostly of water. So it’s pretty accurate to say that a 95 kg person has a volume of 95 liters.)

2. Maximum level

For same reason explained above, a concentrator that puts 10l/min – 95% Oxygen in to the chamber will not influence much the O2 concentration inside the chamber.

40 seconds.

The temperature inside the chamber depends on several factors:

  • Compressor usage time. The longer it is used, the hotter the air being pumped inside the chamber. The cooler is necessary especially when the chamber is being used continuously for more than one hour.
  • Patient’s body heat. Some people’s bodies generate more heat than others, so some people might feel OK without the cooler, while others may not.

Although regulation requires testing at 2.41 ATA for 2 ATA maximum working pressure, we actually tested at 3 ATA pressure with no signs of deformation.

We also had the 2 ATA chamber running for about 4 months now with no signs of weakness.
The AirSep O2 concentrator (139 kPa output) is effective up to 1.7 ATA and for 2 ATA two concentrators are required to provide enough O2 flow inside the chamber.

We have tested several types of oxygen concentrators, Chinese concentrators are only working up to 1.4 ATA and AirSep 10 l/min intensity seems to perform best in a pressurized environment.

Due to our contract with AirSep we receive better prices and we can now sell the concentrator for 1500 Euro when purchased with our chambers.

Biggest risk I have seen with soft chambers is CO2 poisoning in case of power failure. People can fall asleep while in the chamber and there is a power failure. Compressor stops ventilating the chamber, chamber remains inflated like a balloon without exchanging air with the exterior.

There will still be 700 liters of air available, but the building of carbon dioxide inside the chamber is a health hazard. In case of power failure, the OxyHelp chamber depressurizes automatically, door falls down letting the air come inside the chamber. So even when the patient is sleeping and there is no one around, it is totally safe.

4. Warranty and maintenance

What is the general time warranty expected for the OxyLife I oxygen chambers?

Capsule design has been proven to work for at least 3-4 years without any intervention. You won’t have to hassle with much maintenance during the long life of the OxyLife I chamber.

Capsule design has been proven to work for at least 3-4 years without any intervention. The only foreseeable issue after 3-4 years of use is the trim seal around the entrance that will have to be replaced. We prepared video instructions for such procedure and we will also provide the trim seal and the bond. Procedure takes around 2 hours and does not require special skills.

Ongoing costs

Electricity bill, power consumption as follows:

  1. Compressor unit – 380 Watt
  2. Oxygen Concentrator – 650 Watt
  3. Cooling system 500 Watt

Compressor unit

Compressor unit has 2 sets of air filters, 0.05 and 0.01 microns and at 100 l/min flow the filters will work for 20 000 hours. The air pump lifetime is around 8000 hours. Air pump costs – 400 Euro

AirSep Oxygen Concentrator

You will only need to wash the gross particle filter once a week, as per the instructions in owner’s manual, and replace it once every 2 years. The concentrator life is 25 000 – 30 000 hours with proper maintenance. The molecular sieve should be replaced after 10 000 hours.

Cooling system

We have only been using it for about 8 months now, I don’t know of any maintenance requirements, I will ask. I believe you only have to keep the water and cooling gas levels as recommended

The maintenance is described in the user manual. It is basically about keeping the chamber clean and only using neutral detergent. Only wipe window with soft cloth and neutral detergent or water. Spay some silicon oil on the guiding window rails once a moth or whenever you feel the door is not sliding easy. Safety features are explained in the initial email or Oxyhelp catalog.
