What to Expect During Your First HBOT Session
Walking into your first hyperbaric oxygen therapy session, often called HBOT, can feel a little unfamiliar. You may have read about it, or someone may have suggested it, but you probably still have questions. What does the chamber look like? Will it be loud? Will your ears feel strange? These are very common things to wonder about.
At PRN Medical by Yana Ryzhakova in Brooklyn, HBOT is one of many services we offer, and we believe you should know what to expect before you arrive. This post walks through the general flow of a first session so you can feel calm and ready.
What HBOT Actually Is
Hyperbaric oxygen therapy means breathing oxygen while inside a chamber where the air pressure is raised above normal. Think of it as a controlled, gentle change in the environment around you. The oxygen you breathe during a session is delivered in a setting designed for that purpose.
People explore HBOT for different reasons, and whether it makes sense for you depends on your health history and your goals. That is why a first visit usually starts with conversation. Your questions matter as much as the equipment does.
Getting Ready Before You Arrive
Plan to wear soft, comfortable clothing without a lot of metal or hardware. Because oxygen is involved, the team will give you specific instructions about what can and cannot go into the chamber. Items like lighters, certain electronics, and some lotions, oils, or hair products are often restricted in oxygen-rich spaces. Follow the guidance you receive, and ask if you are unsure about something you normally carry or wear.
It also helps to bring a list of your medications and any health conditions you have. If you have a cold, a stuffy nose, allergies flaring up, or any breathing concerns such as asthma, mention it. Congestion can make pressure changes in your ears and sinuses harder to handle, so your care team will want to know before you begin. Let them know too if you are pregnant, if you feel uneasy in small spaces, or if you have had recent surgery or ear problems.
What Happens During the Session
Once you are checked in and your questions have been answered, you will get settled into the chamber. Most people simply lie back or recline and relax. You can expect to hear some hissing or rushing air as the pressure slowly rises, and the space may feel a bit warm.
The most noticeable sensation is usually in the ears. It feels much like descending in an airplane or driving down a steep hill. Swallowing, yawning, or sipping water can help your ears adjust. If you feel pressure that bothers you, tell the team right away so they can adjust the pace. You are not expected to push through discomfort quietly.
Once the chamber reaches its target pressure, you simply breathe and rest. Some people listen to music, nap, or watch something, depending on what is available. Session length can vary, so ask our team what to plan for. Near the end, the pressure is lowered gradually, and your ears may pop again.
After Your First Session
When you step out, take a moment before standing up quickly. Some people feel relaxed, a little tired, lightheaded, or hungry afterward. Others feel completely normal and go on with their day. Mild ear fullness can linger briefly. If anything feels unusual or worrying, contact our team.
How many sessions you might need, and how results look from person to person, depends on your situation, so there is no single answer. Your provider can explain the plan that fits you and how HBOT may work alongside other care you are receiving, such as primary care or IV infusions.
Questions to Bring With You
A first appointment goes best when you feel free to ask anything. You might ask whether HBOT is appropriate given your health history, how often sessions are scheduled, what you should do if your ears feel blocked, or how to prepare on the day of your visit. Ask our team about fees and whether you need a referral, too, so there are no surprises.
