1.8 ATA

A 1.8 ATA chamber is considered a high-performance unit that bridges the gap between "wellness" and "clinical" therapy.

• The Pressure Difference: At 1.8 ATA (Atmospheres Absolute), the internal pressure is equivalent to being approximately 8 metres underwater.
• The Benefit: According to Henry's Law, this higher pressure forces significantly more oxygen to dissolve into your blood plasma, lymph, and cerebrospinal fluid than a 1.3 or 1.5 ATA chamber. This makes 1.8 ATA the preferred choice for athletes seeking rapid recovery, or individuals managing chronic conditions where deep-tissue oxygen saturation is critical.

Yes, but only specific "reinforced" models.

• Standard Soft Shells: Typically top out at 1.3 or 1.5 ATA.
• 1.8 ATA Soft Shells: Our collection features advanced soft chambers engineered with heavy-duty reinforced TPU and external steel frames or expansion belts. These are specifically designed to safely withstand the immense internal force of 1.8 ATA while retaining the portability and lower cost of a soft-sided unit.

The choice depends on your budget and accessibility needs.

• Hard Shell (1.8 ATA+): These are rigid units (stainless steel or polycarbonate) that handle 1.8 ATA effortlessly. They are easier to enter (often featuring sliding doors), offer superior visibility, and can often reach even higher pressures (up to 2.0 ATA) if your needs change.
• Soft Shell (1.8 ATA): These offer the highest pressure available in a portable format. They are ideal if you need high-performance therapy but have limited space or need to move the chamber between rooms, which is impossible with a 150kg hard shell.

Yes, provided you follow the correct protocols.

• Ear Clearing: The descent to 1.8 ATA is deeper than mild chambers. You will feel significant pressure in your ears (like a steep aircraft landing). You must be comfortable performing the Valsalva manoeuvre (holding your nose and blowing gently) to equalise your ears.
• Pressurisation Speed: These chambers are designed to pressurise gradually to give you ample time to adjust. You also have full control of the relief valves from the inside to stop or slow the pressure increase if needed.

To support the higher pressure, the auxiliary equipment must be more powerful.

• Oxygen Concentrator: You typically need a 10L per minute (LPM) medical-grade oxygen concentrator to ensure you receive high-purity oxygen (93%–96%) through your mask against the higher internal pressure.
• Air Compressor: The compressor must be rated for higher duty cycles to maintain the 1.8 ATA environment consistently for 60–90 minutes without overheating.

Because the pressure is higher, the "dose" of oxygen is more potent.

• Duration: A standard session is typically 60 to 90 minutes.
• Frequency: Many users find that at 1.8 ATA, they require fewer weekly sessions to feel the same benefits compared to using a 1.3 ATA pod. A common protocol is 3–4 sessions per week for injury recovery or chronic management.
  
  

Elite athletes often prefer 1.8 ATA because it provides a "flush" effect. The higher pressure is more effective at driving oxygen into tendons, ligaments, and bone tissue—areas with poor blood supply that are notoriously slow to heal. It also helps to rapidly metabolise lactic acid and reduce delayed onset muscle soreness (DOMS) faster than mild pressures.
