Discover the hyperbaric medicine center opened in our clinic. Centrokinetic has the top-performing hyperbaric chamber in Bucharest, with multiple medical and anti-aging uses. The Baroks chamber has 5 seats, and operates at a constant pressure of 2.5 atmospheres, being fully automated and having protocols for each condition, and can be used individually for each patient. 

Hyperbaric oxygen therapy - benefits

Patients who use the clinic's hyperbaric therapy services benefit from:

  • The only medically accredited hyperbaric therapy chamber in Bucharest, which operates at 2.5 atmospheres (those for aesthetic use go to 1 atmosphere and have no medical benefits).
  • A safe medical procedure, without irradiation, without pain, without other side effects. 
  • The specialized medical team consists of recovery doctors, orthopedists, rheumatologists, neurologists, and neurosurgeons, meaning a multidisciplinary team specialized in all diseases that can be treated with hyperbaric therapy. 
  • Premium conditions at a fair price. Our clinic is recognized for the conditions offered and for the care of each patient. But we do not need to pay exorbitant prices to have access to quality medical services. At Centrokinetic you can find an affordable and fair price. But note that we do not have a contract with the National Health Insurance House (we do not offer state reimbursed services)

Centrokinetic is keeping contact with prestigious clinics and universities in Belgium, the Netherlands, France, and Greece to constantly update treatments to provide patients with the best medical solutions.

What is hearing loss?

Sudden sensory hearing loss is defined as a hearing loss of at least 30 decibels that occurs on at least three consecutive frequencies and lasts for at least 3 days. A specific etiology is identified only about 10% to 15% of the time, most of which are considered idiopathic. 

Possible etiologies include vascular occlusion, viral infections, labyrinthine membrane ruptures, autoimmune, trauma, toxins, cochlear membrane damage, demyelinating disease, stroke, and schwannoma. Usually, the patient first observes the symptoms on waking and describes a fullness/sound block. They may also have tinnitus, dizziness, or vertigo. There are about 4,000 new cases in the United States each year. The rate of spontaneous recovery is difficult to determine because many patients do not seek medical care, but it has been reported at 25% and 65%. 

In most controlled studies, spontaneous recovery in patients receiving placebo is between 35% and 39%. Hearing loss can lead to social and economic problems and can significantly affect the patient's quality of life. Hearing loss is the most common cause of disability globally and the third leading cause of lost productivity due to disability, according to the World Health Organization (WHO).

Hearing aids are recommended for moderate (41 decibels to 60 decibels) and severe (61 decibels and higher) hearing loss. Over 60 treatment protocols have been described for sudden hearing loss, but most of them are not effective. The three most promising treatments include corticosteroids, vasodilators, and hyperbaric oxygen therapy. Of these, only hyperbaric oxygen has sufficient randomized controlled trials to provide effective results.


The auditory function in the inner ear is maintained by the cochlea, which is known to have a high oxygen demand. Cochlear hypoxia is associated with progressive ossification, fibrosis, neuronal loss, endolymphatic hydrops, and hearing loss. Direct blood supply to the Corti organ is minimal; oxygen must diffuse through perilemma.

The labyrinthine artery (internal auditory artery) is a long and thin branch outside the inferior anterior cerebellar artery (85%) or the basilar artery (15%). It accompanies the vestibulocochlear nerve through the internal acoustic meatus in the inner ear. Animal models of labyrinthine artery occlusion showed progressive degenerative changes, fibrosis, new bone formation, and hearing loss. Any pathology that results in vascular occlusion of this artery can lead to hearing loss.

Hyperbaric oxygen can increase the tension of oxygen in the perilymph and restore hearing in a significant number of patients with sudden hearing loss. Efficacy can depend on many factors, including the degree of oxygenation of the labyrinthine artery and the ability to increase oxygen stress in the perilymph. Many prospective randomized controlled trials have proven their benefits over other treatments. The best results are found when patients are treated within 14 days of the onset of symptoms and with concomitant steroids (systemic or intratympanic). Steroids should be given at an initial dose of 1 mg/kg/day for 2 to 3 weeks unless such treatment is contraindicated. 

The American Academy of Otolaryngology recommends that hyperbaric oxygen be considered a treatment option for up to 3 months after the onset of symptoms and recommends against the routine use of antivirals, thrombolytics, vasodilators, vasoactive substances, or antioxidants. Patients who have failed to recover with initial steroid treatment can often benefit from a combination of intratympanic steroids and hyperbaric oxygen therapy, even up to ten weeks after the onset of symptoms. 

An otolaryngologist and audiologist should evaluate patients with an audiogram, brain MRI (to rule out retrocochlear pathology), complete autoimmune assessment of vasculitis, and brainstem auditory response. Follow-up audiograms should be performed during (after the first ten sessions) and after (at the end of the 20 sessions) hyperbaric oxygen therapy and at 6 months. Also, patients should be educated about the natural history of the condition, the benefits and risks of interventions, and the limitations of existing evidence on efficacy. Patients should be advised of the possibility of incomplete hearing recovery and the possible benefits of supportive technologies.


Contraindications for hyperbaric oxygen are relatively few but may include: anxiety, severe congestive heart failure, severe reactive respiratory disease, untreated pneumothorax, and doxorubicin or concomitant bleomycin therapy. Systemic corticosteroids may be contraindicated in patients with psychiatric illness, diabetes, diseases such as peptic ulcer, breastfeeding, and liver disease. For these patients, intra-tympanic steroids may be a better option. 


Patients can be treated in a single-seater hyperbaric chamber or in a multiplace chamber.

What are the effects of oxygen therapy on the body?

  • Decreases inflammation
  • Increases the body's oxygen saturation by 20-30%
  • Increases the body's immunity
  • Increases blood circulation and stimulates the formation of new capillaries
  • Decreases toxins in the body
  • Stimulates the production of new blood cells
  • Increases healing rate


Patients should be examined for reversible contraindications, such as fever and hypoglycemia before treatment.


The treatment pressure for hyperbaric oxygen therapy should be from 2.0 ATA to 2.5 ATA for 60 minutes a day for 10 to 20 treatments, depending on the response. Those who did not show any improvement (10 decibels or less) in the first ten treatments are less likely to benefit from additional treatment. 


The middle ear barotrauma is the most common complication of hyperbaric oxygen therapy. Its incidence is about 13%, but the vast majority of these cases are resolved without sequelae. The incidence of middle ear barotrauma can be reduced by using slower compression rates, involving ear cleaning techniques and oral decongestants. The O'Neill rating scale showed greater reliability and utility than the Teed scale in determining the degree of barotrauma and recommended treatment options.

Clinical significance

Moderate to severe hearing loss dramatically affects the quality of life of patients and their families and can affect their ability to work in their chosen career. Hearing aids cost between $ 1,500 and $ 3,000 per pair, requiring replacement every 3 to 5 years, and they do not always give the patient perfect hearing. A course of 10 hyperbaric oxygen treatments at an outpatient center ranges from $ 2,000 to $ 5,000. For people with an early onset of sudden hearing loss, the application of hyperbaric oxygen therapy significantly improves the likelihood of positive results. For patients with moderate hearing loss, hyperbaric oxygen improved hearing by an average of 19.3 decibels and for those with severe hearing loss by approximately 37. 7 decibels. 

Improving the results of the healthcare team

Sensory hearing loss is best treated with the help of a multidisciplinary nurse. Over the years, HBOT has been recommended for the treatment of sensory loss, but clinicians should be aware that the data are heterogeneous and there are still some questions about its real benefits. Results based on a series of small studies seem to suggest that some patients with hearing loss have a positive result, but this is not a universal finding.

Cystoid or cystic intestinal pneumatosis (intestinal emphysema) is a symptom that can occur in many gastrointestinal diseases. Hyperbaric oxygen therapy can be a successful treatment of cystoid intestinal pneumatosis and granulomatosis with polyangiitis.


Hyperbaric oxygen therapy in cell damage caused by radiation in gynecological cancers

Gynecological cancers treated with a combination of external beam radiation and brachytherapy, especially cervical and vaginal cancers, can result in the apex of the vagina receiving a high dose of radiation. Hyperbaric oxygen therapy has positive effects on the radiated tissues, especially the head, neck, anus, and rectum.


Hyperbaric oxygen therapy in post-radiotherapy CNS injury

Hyperbaric oxygen therapy involves the use of so-called levels of oxygen under pressure to increase the level of oxygen in the blood. The use of hyperbaric oxygen therapy involves oxygen treatment for soft tissue radionecrosis. Read this article and find out more.


Hyperbaric oxygenation vs normobaric oxygenation in CO poisoning

Prolonged CO exposure is responsible for more than half of fatal poisonings and is also one of the leading causes of poisoning in Western countries. We aimed to compare the effectiveness of therapy with hyperbaric oxygen (HBO) versus normobaric oxygen (NBO) in the setting of carbon monoxide poisoning (COP).


Hyperbaric oxygen therapy in diabetic foot

Hyperbaric oxygen therapy may be effective for Wagner's grade 3 and 4 diabetic foot ulcers and need to study the real problems with patients seeking treatment and demonstrates the need to study the real problems with patients seeking treatment. The results show that it is important to follow the treatment in order for the HBOT to be efficient.


The role of hyperbaric oxygen therapy in sports medicine

Hyperbaric oxygen is used in sports medicine to reduce hypoxia and edema and is also effective in treating stroke injuries and acute traumatic peripheral ischemia. When used clinically, hyperbaric oxygen should be considered as an adjuvant therapy used as early as possible after the diagnosis of the lesions.


Hyperbaric oxygen therapy in muscle injuries

Muscle stretches are the most common muscle injuries suffered during performance sports. Rapid recovery from muscle injury is crucial for elite athletes who regularly are exposed to training and increased competition. Hyperbaric oxygen therapy is a safe and effective method, being a non-invasive treatment


Hyperbaric oxygen therapy in sports injuries

Hyperbaric therapies are methods used to treat disease or injury using pressures higher than the local atmospheric pressure inside a hyperbaric chamber. The long-term effects are neovascularization (angiogenesis in hypoxic soft tissues), osteoneogenesis, and stimulation of collagen production by fibroblasts. This is beneficial for wound healing and recovery after irradiation.


Hyperbaric oxygen therapy in proctitis generated by radiation

Proctitis is the inflammation of the rectal mucosa causing pain, discharge, and other unusual symptoms. Pain can occur during bowel movements, it can be acute or chronic. Symptoms may vary, but the most common is tenesmus (the feeling of needing to go to the toilet), a sensation that persists even after using the toilet. This treatment should be offered to patients who fail to recover with conventional treatments for radiation-induced proctitis.


Hyperbaric oxygen therapy in refractory osteomyelitis

Osteomyelitis is an infection of the bone or marrow caused by bacteria or mycobacteria. Hyperbaric oxygen treatments can be considered an American Heart Association (AHA) Class II recommendation for the treatment of chronic, refractory osteomyelitis


Hyperbaric oxygen therapy in tinnitus

Hyperbaric oxygenation allows a controlled increase in oxygen pressure in the blood. This technique can be used in cases of tinnitus and sudden deafness, when certain changes in the inner ear and brain generate a lack of oxygen and, therefore, a limited intake of energy.


Hyperbaric oxygen therapy of ischemia and reperfusion injury

Hyperbaric oxygen therapy has been found to ameliorate the damaging effects of reperfusion by early modulation of inflammation, maintenance of metabolic function in downstream tissues, and reintroduction of oxidation scavengers.


Hyperbaric therapy in the treatment of second degree burns

HBOT has a beneficial effect on burn wound healing by reducing edema and ensuring there is adequate oxygen in microcirculation. It may speed up epithelialization and suppress unnecessary inflammation that could negatively affect normal wound healing. With further research, HBOT may become an adjuvant therapy to surgery.


Hyperbaric oxygen therapy

Hyperbaric therapy is a form of medical treatment that involves exposing the body to pure oxygen at a higher pressure than normal. There are about 45 diseases approved worldwide to be treated with hyperbaric oxygen.


Hyperbaric oxygen therapy in the management of patients with malignant otitis externa

Malignant otitis externa is a rapidly spreading bacterial infection that is aggressive and may be fatal if left untreated. Hyperbaric oxygen therapy (HBOT) is a medical treatment in which the entire body is placed in an airtight chamber at increased atmospheric pressure and has been proven to be effective for several different medical conditions.


Hyperbaric oxygen therapy in acute myocardial infarction

If left untreated, MI will lead to the progressive loss of viable cardiomyocytes, impaired heart function, and congestive heart failure. Oxygen cycling therapy serves as a very attractive option for the treatment of myocardial infarction, because it offers some of the greatest benefits while reducing treatment time and inconvenience to the subject.


Hyperbaric oxygen in ischemic ulcers

The present study has demonstrated that adjunct HBOT enhances the reduction of ulcer area and depth at 4 weeks in T2DM patients with ischaemic DFUs. HBOT is known to ensure hyperoxygenation of ischaemic tissue and restoration from hypoxia. Discover the hyperbaric medicine center open in our clinic. Centrokinetic has the top-performing hyperbaric chamber in Bucharest.


Hyperbaric therapy in femoral condylar osteonecrosis

Osteonecrosis of the knee (ONK) is a form of aseptic necrosis resulting from ischemia to subchondral bone tissue. Typically, treatment is invasive. Hyperbaric oxygen therapy (HBOT) may provide a noninvasive alternative by improving oxygenation and reperfusion of ischemic areas. This study evaluates the efficacy of HBOT in a series of ONK patients.


Hyperbaric therapy in femoral head necrosis

Femoral head necrosis (FHN), also called avascular necrosis, or femoral head osteonecrosis is a common multifactorial condition that affects patients of any age and can lead to substantial clinical morbidity. Hyperbaric oxygen therapy (HBO) is one of the proposed treatments. Indeed, tissue oxygen promotes angiogenesis that reduces edema. Read about the effectiveness of this treatment.


Hyperbaric oxygen therapy in central retinal artery occlusion

Central retinal artery occlusion (CRAO) is a devastating and common eye condition. It presents a sudden, unilateral, and painless loss of vision. Even when treated promptly, an acute obstruction of the central retinal artery usually leads to severe and permanent loss of vision.


Hyperbaric therapy in irradiated maxillofacial dental implant

There are numerous studies reported for the effectiveness of HBO in the treatment of osteoradionecrosis of various bone tissues. In addition to its usefulness in treating osteoradionecrosis, this therapy can prevent it. It also combats the negative effect of irradiation, stimulates osseointegration, and improves the survival rate of the implant.


Hyperbaric oxygen therapy in hear loss

The auditory function in the inner ear is maintained by the cochlea, which is known to have a high oxygen demand. Hyperbaric oxygen can increase the tension of oxygen in the perilymph and restore hearing in a significant number of patients with sudden hearing loss. Patients can be treated in a single-seater hyperbaric chamber or in a multiplace chamber.


Hyperbaric therapy in traumatic ischemia

Limb trauma, which leads to direct tissue damage, plus local hypoxic disorders caused by the resulting edema, causes acute peripheral ischemia. Surgical treatment and hyperbaric oxygen are not concurrent treatment modalities but are best used to complement each other in order to provide the best outcome for the patient.


Hyperbaric therapy in venous embolism

Small gas embolisms, as in this case, present serious risks, especially the complication of cerebral air embolism. To prevent neurological complications, it is necessary to urgently remove the air bubble. HBOT reduces the volume of the bubble, helps eliminate nitrogen, and improves the oxygenation of potentially hypoxic tissue. See the results of hyperbaric therapy in venous embolism.


Hyperbaric therapy in osteoradionecrosis

Osteoradionecrosis (ORN) is a common consequence of radiation provided to cancer patients. Currently, hyperbaric oxygen therapy (HBOT) has a major role in improving wound healing in patients with ORN.


Hyperbaric oxygen therapy in soft tissue radionecrosis

Discover the hyperbaric medicine center open in our clinic. Centrokinetic has the top-performing hyperbaric chamber in Bucharest, with multiple medical and anti-aging uses. The Baroks chamber has 5 seats, and operates at a constant pressure of 2.5 atmospheres, being fully automated and having protocols for each condition, and can be used individually for each patient.
