Hyperbaric Oxygen Therapy (HBOT) is a medical treatment that involves breathing 100% oxygen in a pressurized chamber. It’s used to promote healing and is prescribed for various conditions like wound healing, decompression sickness, certain infections, and even brain injuries. If you're about to have your first HBOT session, here’s what to expect from this unique experience and how to prepare.
Pre-Session Preparation
Before your session, you’ll likely have a consultation with the hyperbaric oxygen treatment in NYC therapist or doctor to discuss your health history and reasons for treatment. This is the time to mention any medical conditions, medications, or concerns you may have. You may be advised to avoid certain products, like lotions, perfumes, and makeup, as they can interfere with oxygen levels in the chamber. Jewelry, electronics, and flammable items are also generally prohibited for safety reasons. Dress in comfortable, loose clothing; some centers will provide a special gown.
The Hyperbaric Chamber and Environment
Once you’re ready, you’ll be led to the hyperbaric chamber, which might look like a large, clear cylinder or even resemble a small room. There are two main types of chambers: monoplace (for one person) and multiplace (accommodates several people at once). Multiplace chambers are generally larger and may feel more open, while monoplace chambers are typically smaller and more private.
Inside the chamber, you’ll be instructed to lie down or sit comfortably. Your therapist will explain the steps and let you know how to communicate if you feel any discomfort. The chamber is designed for comfort and safety, with many facilities offering pillows, blankets, and even entertainment, like a TV or music, to help you relax.
Pressurization and Breathing
Once you’re settled, the chamber will begin to pressurize, which may take a few minutes. As the pressure increases, you might feel a sensation similar to being on an airplane or going underwater – pressure in your ears. You can relieve this by yawning, swallowing, or gently pinching your nose and blowing out. Your therapist will guide you through this if needed.
During the session, you’ll be breathing pure oxygen. The elevated pressure enables your lungs to absorb more oxygen than under normal atmospheric conditions, which helps distribute oxygen to tissues and promotes healing. Many people feel relaxed and even a bit sleepy due to the increased oxygen flow.
Session Duration and Monitoring
The typical HBOT session lasts between 60 to 90 minutes. While inside the chamber, you’ll be continuously monitored to ensure your safety and comfort. Your therapist will check in periodically to confirm that everything is going well and address any needs that might arise.
During the session, it’s normal to experience mild warmth, but most people find it soothing and calm. Many use this time to rest, meditate, or even nap. The environment is intentionally kept quiet, with minimal disturbances.
Post-Session Effects and Recovery
After the session, the chamber will slowly depressurize. This might feel like the reverse of the pressurization phase, and you might notice your ears needing to “pop” again. Once the session is over, you may feel refreshed and energized, though some people report mild fatigue.
HBOT is generally very safe, but some people might experience temporary side effects like ear discomfort, lightheadedness, or, in rare cases, oxygen toxicity. Your therapist will provide any aftercare instructions if needed and address potential side effects.
