Hypoxia Zones

Hypoxia Zones in Airvana refer to moments during breathwork sessions when your blood oxygen saturation (SpO₂) drops to 90% or below. 

These temporary low-oxygen states are intentionally induced and carefully monitored using our medical-grade pulse oximeter.

We categorize these zones by SpO₂ levels:

90–71% – Green Zone (mild hypoxia)

70–61% – Yellow Zone (moderate hypoxia)

60–51% – Orange Zone (significant hypoxia)

Below 50% – Red Zone (deep hypoxia)

Each zone reflects the physiological impact of the breathwork exercise. 

Entering a hypoxia zone MAY stimulate adaptations such as:

- Improved oxygen efficiency

- Increased red blood cell production

- Enhanced cardiovascular and respiratory performance

- Stress resilience and nervous system regulation

Airvana tracks and visualizes these intervals in real-time, helping users and coaches understand how effectively the body responds to breath-hold and retention exercises.

Note: All sessions are designed to remain within safe, scientifically supported limits. Users with medical conditions should consult a healthcare professional before engaging in breath-hold practices.
