Hyperbaric Oxygen Chamber 2.0 ATA: What to Verify

The 1 quote says 2.0 ATA and the other 1 about 14.7 psi, which looks like two different grades. The real error-prone place is not in the size of the number, but in the pressure reference point. Without a clear separation between absolute pressure and gauge pressure, it is not possible to confirm that the two specifications are describing the same state.

When purchasing hyperbaric oxygen chamber 2.0 ata, first check the pressure caliber, then look at the cabin, oxygen supply, site and documents. A striking ATA value alone can neither determine which purpose the device is suitable for, nor whether it meets the target market requirements.

First, Replace the 2.0 ATA With the Same Caliber

ATA refers to absolute pressure, with absolute vacuum as the zero point. 2.0 ATA is equal to the 202.6 5kpa absolute pressure, which is approximately equal to 29.3918 psia. Under standard sea level conditions, it corresponds to a 101.32 5kpa gauge pressure of about 14.6959 psig.

Therefore, when the supplier writes 2 atm or 2 atmospheres, confirm whether it refers to 2.0 ATA absolute pressure or an additional 2 atm above ambient pressure. It is not enough to write only psi. psia or psig should be specified on request and the corresponding ATA absolute pressure should be given. Altitude and weather will change the local ambient atmospheric pressure, and the local ambient pressure will be used to convert the absolute pressure to the gauge pressure on the site.

Don‘t Let a Single Number Stand In for the Three Types of Stress

The specification sheet shall at least distinguish between normal working pressure, maximum allowable working pressure and pressure relief device set pressure. The device up to 2.0 ATA is not the same thing as normally working at 2.0 ATA, and the maximum pressure is not equal to the pressure in the specific usage plan.

When comparing 1.5 ATA and 2.0 ATA devices, do not sort by numbers only. Higher pressure does not automatically lead to better applicability, efficacy, or safety. Also check the intended use, structural design, pressurized medium, user breathing gas, operating instructions and supervision requirements.

2.0 ATA Cannot Yet Independently Define the Devices Purpose

The current UHMS clinical hyperbaric oxygen definition involves breathing medical grade oxygen at a pressure of no less than 2.0 ATA, all over the body in a hardware chamber conforming to the corresponding pressure vessel and fire protection code. The pressure here is only one of the thresholds, not a complete determination condition.

A device reaches 2.0 ATA, which cannot be inferred that it is approved for a certain market, suitable for a certain disease, or qualified for clinical use. When purchasing for medical use, check the specific manufacturer, complete model, intended use, target market approval, pressure vessel and fire protection requirements, and professional staffing. The presence of oxygen in the trade name also does not justify the use of pure or medical grade oxygen in the cabin.

Inferring the Specific Model From Posture and Number of People

Baobangs existing 2.0 ATA hardware cabin is not only in 1 form. HP2202 is a horizontal model, available in 75, 85 and 90cm diameters; HP2202 DIA is also horizontal, with enlarged transparent windows, available in 90 and 100cm diameters. Both are 220cm in length, and should be selected in combination with the way of entry and exit, internal space and user posture, rather than just looking at the appearance.

When you need a sitting single-person structure, you can check the 96cm wide HP750. HE5000 Mono uses walk-in transparent doors; HE5000 Fort, HE5000 and HE5000 Plus are for multi-person layout, of which HE5000 can be configured with two seats, 3 seats, bed boards or benches, HE5000 Plus can accommodate four people and supports internal layout customization. The headcount label is still not a substitute for entry size, crew rating, cabin crew location, and emergency evacuation conditions.

These devices vary significantly in both weight and外形. The site assessment should cover the transportation channel, door width, turning space, ground bearing, power supply, ventilation, fire protection and maintenance space in advance, and cannot wait for the equipment to arrive before processing.

Let Quotation and Deliverables Correspond Item by Item

The formal quotation shall state the manufacturer, brand, complete model, sub-model, equipment status and place of manufacture, together with the configuration list, technical specifications, labels, instructions for use, installation conditions, maintenance plan and safety documents. The oxygen supply part also needs to write down the pressurized medium, the inhaled gas, the oxygen concentration, the interface, the flow rate and the exhaust mode.

For the US market, the 510(k) records under the product code CBF should be checked against the manufacturer and specific equipment, and cannot be replaced by the company registration number, similar model number or license of other companies. The statement of the pressure-bearing structure shall also correspond to the applicable standard version, holder, type, place of manufacture and effective range.

Finally, the model, serial number or unique identification of the physical equipment is linked to the contract, license, manual and maintenance records. If the supplier cannot explain what kind of pressure "2.0 ATA" is 1 and under which working state, this equipment does not have a comparable foundation.
