What is the Pressure in a Hyperbaric Chamber?

Understanding the Pressure and Atmospheres Inside the hyperbaric chamber can be confusing. The maths involves applying oxygen (gas) under pressure. However, a quick lesson in physics is needed to understand the basics of a hyperbaric chamber. Let’s make this easy for you!

The pressure inside the chamber increases to higher than atmospheric pressure. This increase in pressure is measured in the atmosphere’s absolute (ATA). For example, the pressure inside the chamber may increase to 2.0 ATA, two times greater than normal atmospheric pressure at sea level.

As a technician and trained professional, you must understand the pressure inside a hyperbaric oxygen chamber and how to operate this component seamlessly to achieve the desired result for your patient. Read on as we demystify a hyperbaric chamber’s PSI, ATA, and oxygen therapy.

What is Hyperbaric Oxygen Therapy (HBOT)?

HBOT involves a patient breathing pure oxygen in a pressurized chamber. The pressure inside the chamber is higher than atmospheric pressure, which can increase the amount of oxygen available to the body’s tissues.

Hyperbaric oxygen therapy (HBOT) typically involves increasing the pressure inside the chamber to 1.3 to 3.0 atmospheres absolute (ATA). This equals approximately 17.7 to 45.4 pounds per square inch (psi). The pressure can be adjusted based on the individual’s medical condition, severity, and tolerance to the treatment.

What is PSI Hyperbaric Oxygen Therapy?

Pounds per Square Inch (PSI), a unit of pressure, is commonly used to measure the pressure in hyperbaric oxygen therapy. Hyperbaric oxygen therapy involves administering oxygen at increased atmospheric pressure, typically between 1.3 and 3.0 atmospheres absolute (ATA).

The increased pressure in the device supplies higher oxygen levels to the body tissues, which help treat various medical conditions. The specific pressure in hyperbaric oxygen therapy depends on the treated condition and the physician’s recommendation.

What is Hyperbaric Oxygen at 1.4 ATA?

At a pressure of 1.4 ATA (atmospheres absolute), the partial pressure of oxygen inside a hyperbaric chamber is increased to approximately 1.4 times that of normal atmospheric pressure. This increased pressure of oxygen can help to promote healing and tissue repair in certain medical conditions.

Oxygenark hyperbaric chamber at 1.4 ATA is commonly used to treat conditions such as

  • Carbon monoxide poisoning
  • Diabetic ulcers
  • Radiation injuries, etc.

However, it is crucial to note that the specific pressure used in hyperbaric therapy should only be determined by a qualified medical professional based on the patient’s needs and medical condition.

What is 2 ATA in PSI?

2 ATA (atmospheres absolute) equals 29.4 pounds per square inch (psi). This means that in a hyperbaric chamber with a pressure of 2 ATA, the atmospheric pressure inside the chamber is twice the normal atmospheric pressure at sea level.

How Many Atmospheres are in a Hyperbaric Chamber?

The number of atmospheres in a hyperbaric chamber can vary depending on the treatment. Typically, hyperbaric oxygen therapy involves increasing the atmospheric pressure to 1.3 and 3.0 atmospheres absolute (ATA). One atmosphere equals the normal atmospheric pressure at sea level, approximately 14.7 pounds per square inch (psi).

Therefore, a hyperbaric chamber may contain 1.3 to 3.0 times the normal atmospheric pressure or 19.11 to 44.1 psi. The specific pressure in hyperbaric therapy will depend on the treated condition and the physician’s recommendation. It is important to note that qualified medical professionals in specialized facilities should only administer hyperbaric therapy.

The pressure in a hyperbaric chamber can vary depending on the treatment. Generally, the pressure is increased to 1.3 to 3.0 atmospheres absolute (ATA), equivalent to 17.7 to 45.4 pounds per square inch (psi). This increased pressure allows higher oxygen levels in the body tissues, which can help treat various medical conditions.

What Is the Pressure in the Chamber Used for?

Higher pressures can be used for more severe conditions, such as decompression sickness or carbon monoxide poisoning. For example, a pressure of 2.5 ATA may be used for decompression sickness, while a pressure of 2.8 ATA may be used for carbon monoxide poisoning.

It is important to note that qualified medical professionals in specialized facilities should only administer hyperbaric therapy. The pressure inside the chamber can have positive and negative effects on the body, and the treatment should be closely monitored to avoid any potential complications.

Hyperbaric chambers are designed to expose the body to high pressure and oxygen levels to help treat various medical conditions. The pressure inside the chamber can be adjusted to different levels depending on the patient’s needs and the treated condition.

Hyperbaric Chamber Pressure: Effects on the Body

The pressure inside the chamber has several significant effects on the body. The increased pressure causes oxygen to dissolve into the blood plasma and other body fluids, increasing the oxygen released to the body’s tissues. This can be particularly advantageous to individuals with conditions such as carbon monoxide poisoning, where oxygen delivery to tissues is impaired.

However, the increased pressure can also negatively affect the body if not managed properly. For example, it can lead to barotrauma, which damages the body’s tissues caused by pressure changes. This can be particularly worrisome for individuals with lung or sinus issues, as the pressure changes can cause pain and discomfort.

How Long Does it Take for A Hyperbaric Chamber to Depressurize?

On average, the therapy session lasts for about 2 hours or more. The duration includes the time to pressurize and depressurize the chamber. However, the pressure inside a hyperbaric chamber can be adjusted/depressurized to different levels depending on the individual’s medical condition and the severity of the condition being treated.
