Hyperbaric oxygen therapy (HBOT) chambers offer a range of benefits, such as improved wound healing, increased oxygen delivery to tissues, and enhanced overall wellness. Different types of chambers operate at specific pressure ranges, with many at-home chambers typically operating between 1.3 and 3.0 ATA (atmospheres absolute). Choosing the right ATA for your hyperbaric chamber is key to ensuring the treatment’s efficacy and safety. Use our tips to determine which pressure setting is optimal for your goals.
Understand Chamber ATA
ATA is the total pressure within a hyperbaric chamber, including both atmospheric pressure and the added pressure from the chamber itself. The increased pressure significantly enhances the amount of oxygen that can dissolve into the bloodstream and tissues. The standard atmospheric pressure at sea level is 1 ATA, and any additional pressure applied in a hyperbaric chamber will increase this value, tailoring the treatment to the user’s specific health requirements.
To achieve the desired ATA, a compression mechanism gradually increases the pressure inside the chamber. The chamber is engineered to withstand the increased pressure, maintaining an airtight environment where pressure can be accurately controlled and adjusted as needed. Safety features, such as pressure release valves, emergency stop controls, and robust structural materials, are integral to prevent over-pressurization and ensure the safety and comfort of the user during therapy sessions.
Define Intended Use
Your reason for investing in a hyperbaric chamber is a key consideration when choosing the right ATA. Clearly defining whether your chamber is for medical-grade treatment or lifestyle enhancements can help you narrow down your options. Consult a healthcare professional or hyperbaric specialist to determine the appropriate ATA setting that aligns with your medical or wellness goals.
People use hyperbaric chambers for the following purposes, among others:
- Treating specific conditions: Hyperbaric oxygen therapy can be used to support healing for conditions like chronic wounds.
- Speeding recovery: Athletes and individuals can use HBOT to accelerate recovery from injuries by enhancing oxygen delivery to damaged tissues.
- Gaining anti-aging benefits: Some users turn to HBOT for its potential anti-aging effects, including improved skin health and cellular regeneration.
- Boosting immune function: Regular sessions in a hyperbaric chamber may help boost the immune system by increasing oxygen availability to vital organs.
- Enhancing cognitive function: There is emerging interest in utilizing HBOT to potentially improve cognitive function and mental clarity, especially for age-related cognitive decline.
In general, lower ATA levels are often suitable for overall wellness and mild therapeutic purposes, such as enhancing general recovery and boosting the immune system. Higher ATA levels are typically required for more intensive treatments.

Consider Portability
Portable hyperbaric chambers enhance convenience and accessibility. Portable chambers have soft shells that allow users to enjoy treatment sessions at home or even while traveling. Crafted from high-quality, medical-grade TPU materials, these chambers are built for safety, durability, and compliance with health standards. Their easy setup and dismantling make them a great option for individuals who need regular sessions but have limited space or a more on-the-go lifestyle.
These portable chambers come in both vertical and horizontal designs to suit different preferences and space needs. Typically operating within a range of 1.3 to 1.5 ATA, they are perfect for mild therapeutic purposes. With their flexibility and accessibility, portable hyperbaric chambers are an appealing choice for anyone looking to experience the advantages of hyperbaric oxygen therapy.
Follow Safety Standards
All chambers and their specified ATA levels must meet strict industry safety guidelines, such as ISO standards for hyperbaric oxygen systems. Buying a hyperbaric chamber from a reputable manufacturer ensures industry-approved quality and minimizes risks such as pressure malfunctions. For example, the 3 ATA hyperbaric chambers we offer at Hyperbaric Pro have penta-welded seams, multiple pressure-regulating valves, and other enhanced features to ensure safety at these higher pressure levels.
Additionally, consider features that offer extra security, like pressure regulation systems and emergency release valves. These add-ons can provide peace of mind during sessions and protect against accidental over-pressurization. Verifying that your chamber conforms to established safety protocols guarantees a safe and hassle-free experience.
The Importance of Maintenance
Maintaining your HBOT chamber according to the manufacturer’s standards is crucial to ensure it can safely reach and stay at the stated pressure rating. Regular tasks include checking the seals for leaks, inspecting valves to confirm they function correctly, and examining the chamber materials for any signs of wear or damage. Maintenance may also involve cleaning components to prevent debris buildup and ensuring ventilation systems operate efficiently. Adhering to these guidelines not only enhances user safety but also keeps the chamber performing optimally over time.

Assess Ease of Operation
User-friendly controls are an essential feature of any hyperbaric chamber. A chamber’s ATA should be easy to adjust and monitor to accommodate different sessions and treatments. Look for interfaces that offer simple, intuitive controls, as well as clear readouts for monitoring pressure levels.
Ease of operation also enhances the overall experience, particularly for first-time users or those without technical expertise. Options like pre-set pressure levels and one-touch controls can simplify the process and make sessions more enjoyable and efficient. Additionally, the easier your chamber is to use, the more likely you are to incorporate HBOT into your routine.
Consider a Multiplace Chamber
Multiplace hyperbaric chambers accommodate multiple individuals simultaneously, providing a communal therapeutic experience. These chambers are typically used in clinical settings and wellness centers and can reach significantly higher ATA levels than personal chambers, making them suitable for treating a range of medical conditions.
One of the key benefits of multiplace chambers is their ability to offer oxygen therapy in a social setting, allowing patients to interact and support one another during treatment sessions. When determining the right ATA for a multiplace chamber, it is crucial to consider the specific needs of each occupant and the intended therapeutic outcomes. Working with hyperbaric specialists to customize the ATA settings ensures the treatment is both safe and effective for all users.
Seek Expert Advice
Consulting a specialist in hyperbaric therapy or your chamber’s manufacturer can provide valuable insights that guide your decision. These experts can offer advice tailored to your specific condition and clarify complex aspects of hyperbaric technology, such as ATA variances or advanced settings. Their professional input ensures that the chamber you choose aligns perfectly with your expectations.
