Question 1

What is Hyperbaric Oxygen Therapy (HBOT )?

Accepted Answer

Hyperbaric Oxygen Therapy (HBOT) is a medical treatment that enhances the body's natural healing process by inhalation of 100% oxygen in a pressurized chamber. Under normal circumstances, oxygen is transported throughout the body only by red blood cells. With HBOT, oxygen is dissolved into all body fluids including plasma, cerebrospinal fluid, lymph, and bone, allowing extra oxygen to reach damaged tissues and support the body's healing process. It is a simple, non-invasive, and painless treatment prescribed by physicians for UHMS-approved medical conditions.

Question 2

How does HBOT work and why is it effective?

Accepted Answer

HBOT works by increasing atmospheric pressure in a sealed chamber while patients breathe 100% oxygen. This elevated pressure allows oxygen to dissolve into all body fluids, reaching areas where circulation is diminished or blocked. At the cellular level, HBOT enhances the ability of white blood cells to kill bacteria, reduces swelling, promotes new blood vessel growth, and improves mitochondrial function. The increased oxygen availability allows tissues to heal naturally, making HBOT effective for wounds, infections, radiation injuries, hearing loss, and other conditions where inadequate oxygen prevents healing.

Question 3

Is HBOT safe? What are the risks?

Accepted Answer

Yes, HBOT is generally safe when prescribed by a physician and performed under medical supervision. Asia Hyperbaric Centre uses government-certified chambers with medical-grade oxygen (99.5% purity) and UHMS/DDRC certification. While all medical treatments carry minor risks, HBOT side effects are typically temporary and manageable. The most common side effect is barotrauma (ear/sinus pressure), similar to airplane travel. Rare side effects include temporary vision changes or oxygen toxicity. Your hyperbaric physician will discuss specific risks during your evaluation and tailor your treatment plan to minimize them.

Question 4

What should I expect during my first HBOT treatment?

Accepted Answer

Your first treatment begins with a consultation where the hyperbaric physician performs a history and physical examination. You'll meet with the respiratory therapist who explains the treatment process and safety precautions. During treatment, you'll change into approved cotton clothing, have vital signs checked, and be positioned comfortably on a reclining bed inside the clear acrylic chamber. As the chamber pressurizes, you may feel ear pressure similar to airplane travel. You'll breathe 100% oxygen through a hood, with two air breaks during the session. The chamber is pressurized to approximately 2.4 atmospheres absolute (45 feet equivalent depth). You can watch television, listen to music, or rest during treatment. A technician monitors you continuously via intercom.

Question 5

How long is each treatment session and how many will I need?

Accepted Answer

A typical HBOT treatment session lasts approximately 2 hours, including compression, oxygen breathing periods, and decompression. The number of treatments varies depending on your specific condition and response to therapy. Many conditions require 20-30 treatments over 4-6 weeks. Emergency conditions may require only 1-2 treatments, while chronic conditions like diabetic wounds or radiation injuries may require 30-80 treatments. Your hyperbaric physician will determine your personalized treatment plan during your initial evaluation based on your medical condition, imaging results, and healing response.

Question 6

How often are HBOT treatments scheduled?

Accepted Answer

Most treatment plans involve daily sessions, typically Monday through Friday (5 days per week), with weekends off for tissue recovery. Some conditions may require 4-day-per-week schedules. Each session lasts approximately 2 hours. The frequency is important because regular, consistent treatment allows tissues to heal optimally. Irregular therapy can reduce effectiveness. Your hyperbaric physician will recommend the specific schedule based on your condition. At Asia Hyperbaric Centre, we work with patients to accommodate their schedules while maintaining treatment effectiveness.

Question 7

Do I need a doctor's referral to receive HBOT at Asia Hyperbaric Centre?

Accepted Answer

Yes, a doctor's referral is required for all HBOT treatments at Asia Hyperbaric Centre. HBOT is a prescribed medical treatment, and your physician must provide a referral for evaluation by our hyperbaric medicine team. Your referring physician should indicate your medical condition and why HBOT is being considered. During your evaluation, our hyperbaric physicians will review your medical history, imaging, and test results to determine if HBOT is appropriate for your condition. If you don't have a referring physician, our team can assist you in connecting with an appropriate medical provider.

Question 8

How should I prepare for HBOT treatment?

Accepted Answer

Preparation for HBOT is straightforward. Wear only clean cotton clothing (no synthetic materials). Avoid cosmetics, perfumes, hairspray, deodorants, wigs, and jewelry before treatment. Do not consume alcohol or carbonated beverages for 4 hours prior to treatment. Eat a light meal 2-3 hours before treatment to prevent low blood sugar. Inform your technician of any cold, flu symptoms, fever, sinus congestion, or medication changes. If diabetic, take your insulin as prescribed and eat normally. Avoid smoking and tobacco products during your treatment period as they interfere with oxygen transport. Bring photo ID, insurance card, current medication list, and list of medical providers to your first appointment.

Question 9

What items are prohibited in the hyperbaric chamber?

Accepted Answer

For safety reasons, only approved items are allowed in the chamber. Prohibited items include: cosmetics, perfume, aftershave, hairspray, hair oils, wigs, hairpieces, false eyelashes, nail polish, alcohol or petroleum-based products, cell phones and electronic devices, metallic items (jewelry, keys, coins, titanium eyeglasses), flammable items (lighters, cigarettes, heating pads), hearing aids, paper products (books, magazines), food, gum, and candy. Contact lenses and glasses may be allowed depending on the material. Medical devices and implants must be discussed with the hyperbaric team. You will undergo a safety screening before each treatment to ensure chamber safety.

Question 10

What are the common side effects of HBOT?

Accepted Answer

The most common side effect is barotrauma to the ears and sinuses caused by pressure changes during compression. This is usually mild and manageable using ear-clearing techniques taught by your technician. Some patients experience temporary vision changes during their treatment period, which typically resolve within weeks after completing therapy. Occasionally, patients may experience mild anxiety or claustrophobia, which can be managed with pre-medication if necessary. A rare side effect is oxygen toxicity from excessive oxygen administration. Blood sugar drops can occur in diabetic patients and are prevented by proper screening and meal timing. Most side effects are temporary and resolve after treatment completion.

Question 11

What is barotrauma and how is it prevented?

Accepted Answer

Barotrauma is discomfort or injury to the ears and sinuses caused by pressure changes during chamber compression, similar to airplane ear. Prevention is straightforward: learn and practice ear-clearing techniques taught by your respiratory therapist, such as the Valsalva maneuver, Toynbee maneuver, or Otovent balloon. These techniques equalize pressure between your middle ear and the chamber. If you have difficulty clearing your ears naturally, your physician may recommend decongestants or prescribe ear tubes. Inform your technician immediately if you experience ear pain during compression. Never force pressure equalization. Proper technique prevents barotrauma in over 90% of patients.

Question 12

Will my insurance cover HBOT treatment?

Accepted Answer

Medicare and most private insurance plans cover HBOT for UHMS-approved medical conditions, which include air or gas embolism, carbon monoxide poisoning, decompression sickness, diabetic wounds, hearing loss, radiation injuries, bone infections, necrotizing infections, and many others. Coverage varies by insurance plan and specific condition. Asia Hyperbaric Centre will verify your insurance coverage before starting treatment. If your insurance requires prior authorization, we will obtain it on your behalf. Any financial concerns or questions about coverage should be discussed with our billing staff in advance. We work with patients to understand their coverage and financial responsibility.

Question 13

Can I drive to and from my HBOT appointments?

Accepted Answer

Yes, most patients can safely drive themselves to and from HBOT appointments. Each appointment takes approximately 2.5 hours total (including check-in, treatment, and post-treatment). You should not experience impaired judgment or coordination from HBOT. However, if you experience dizziness, vision changes, or feel unwell after treatment, arrange alternative transportation. Patients on certain medications or with specific medical conditions should discuss driving safety with their hyperbaric physician. Plan to arrive 15-20 minutes early for your appointment to allow time for check-in and vital sign assessment.

Question 14

How effective is HBOT for sudden hearing loss (SSNHL)?

Accepted Answer

HBOT is an UHMS-approved treatment for Idiopathic Sudden Sensorineural Hearing Loss (ISSNHL) and has shown significant effectiveness when started promptly after hearing loss occurs. The increased oxygen availability helps restore function to damaged inner ear cells and promotes healing of the cochlea and auditory nerve. Success rates are highest when treatment begins within 2-4 weeks of hearing loss onset. Many patients experience partial or complete hearing recovery. Treatment typically involves 20-40 sessions over 4-8 weeks. Results vary by individual, severity of hearing loss, and time since onset. Your audiologist and hyperbaric physician will work together to monitor your hearing improvement throughout treatment. Early intervention is critical for best outcomes.

Question 15

Can HBOT help with non-healing wounds and diabetic foot ulcers?

Accepted Answer

Yes, HBOT is an UHMS-approved treatment for non-healing wounds and diabetic foot ulcers. It works by increasing oxygen availability to damaged tissues, promoting new blood vessel growth, enhancing white blood cell function to fight infection, and stimulating the body's natural healing response. HBOT is particularly effective for diabetic wounds because diabetes impairs normal healing mechanisms. Treatment typically involves 20-40 sessions over 4-8 weeks, depending on wound severity and response. Success rates for diabetic foot ulcer healing are significantly improved with HBOT combined with standard wound care. Your wound care team and hyperbaric physician will monitor healing progress with regular wound measurements and imaging. Early intervention with HBOT can prevent amputation and promote limb salvage.
