Hyperbaric medicine is used to treat distinct problems of health and illness, such as severe anemia, cerebral lesions, cerebrospinal fluid, carbon monoxide intoxication, among many others. Since the outbreak of the Covid-19 pandemic, some institutions have been applying it as a complement to the treatment of coronavirus in some patients.
Also known as hyperbaric oxygen therapy (OHB), this therapy is based on the medical application of 100% pure oxygen in a presurmated chamber, with pressures of three to three mayors exceeding the ambient pressure to the level of the sea.
The oxygen applied to these pressures is made more soluble in blood and ingests all the tejidos, eliminating the hypoxia (lack of oxygen) of a more effective way than any other method.
The primers that utilize hyperbaric oxygen (OHB) in patients with Covid-19 carry Chinese medicine, which will demonstrate a rapid recovery in oxygen recovery throughout the organism, affected by the disease.
De hecho, the UHMS (Undersese en Hyperbariese mediese vereniging), an international rector society in this field of medicine, found its ojos in the investigation that lvevaron a cabo and recommend and estimate the realization of more work in this style evidence all the world.
Preliminary results in a pequeña cantidad de patient are located in some hyperbaric medicine centers in EE.UU. y of Suecia.
Mariana Cannellotto, President of the Argentine Association of Hyperbaric Medicine and Research (AAMHEI), Clarín There are currently a number of scientific works published on cases in Europe, in the United States and in Canada, and the results recorded are now that the OHB can contribute favorably to the recovery of patients with hypoxemic neuron by Covid-19 avoids, in some cases, that the patient needs to lie down on the respirator and reduce the risk of multi-organ failure caused by hypoxemia and complications, if applied later.
In Argentina it is applied in three hospitals: Santojanni, Muñiz and the Central of San Isidro.
“However, we have already heard about Covid-19, but have done more studies to confirm it. The significant difference of the OHB in relation to other treatments is that is indicated as adyuvante, it is said, together with the treatment are indicated. It is a complement that allows to increase the oxygen content of the tejidos, reduce cellular oxidative stress, reduce inflammatory interleucinas, increase immunity and repair the tejidos caused by the oxygen deficiency “, explains Cannellotto.

In relation to the experience accumulated in the pandemic market, the physician Nina Subbotina, professor of medicine and author of books on hyperbaric medicine, said to Clarín that “the OHB’s efficacy demonstrated in the treatment of patients with Covid decrease the need for intubation and mechanical respiratory assistance in severe patients and manifestly reducing mortality between severe cases, severity and moderation using a patient scoring system that promotes excellent results stratification and allows comparison with international data.
Subbotina, who was born in the former Soviet Union and since 1992 has lived in Argentina to attend a congress of Hyperbaric Medicine, claiming that hyperbaric oxygen helps treat extreme hypoxia, a characteristic of the new coronavirus SAR.
“Oxygen saturation recovers hasta los valores acceptances from the first sessions of OHB the normal values mean that the treatment is advanced. Hyperbaric oxygen provides the typical cytoquine action for this disease, responsible for the critical evolution of patients. Compensates for the depletion of oxygen which accumulates rapidly and recovers the state of the immune system. It is very important in its anti-inflammatory effect “, says Subbotina, who leads the superior course of hyperbaric medicine designated by the Argentine Medical Association (AMA).

Treatment characteristics
In terms of the form of administration, Cannellotto explains that the patient enters the hyperbaric chamber, where the saturation takes place and an oxygen mask with reservoir is placed, the chamber is closed and the presurization process therefore increasing the inside of the chamber in progressive form has the treatment pressure in the protocol (in Argentina it is 1.45 ATM).
The treatment time for patients with Covid-19 is 90 minutes. The session culminates, the process of desertion begins, it returns to the patient’s room and controls the posterior saturation. The number of sessions varies from 5 to 10 in diary form.
“The objective of the OHB is to log a mayor oxygen dissolution in the plasma. Independently of its transport by hemoglobin and the greater extent of the difference in the tejidos, through the diffusion and penetration of O2 from the plasma to all the cells, the OHB generates a hyperoxia (excess of oxygen) “, called the medicine .
“In patients with hypoxemic neonatal neoplasm by Covid-19 continuous- the oxygen does not properly diffuse from the red blood cell to the inflammation that occurs in the same way, it is affect oxygen transport, the offer of the same, the cellular respiration and the energy production by the cell, leading to a cascade of physiopathological events with empowerment of the cellular functions and multiorganic fall. “
“To increase pulmonary capillary diffusion, the OHB allows mayor dissociation of oxygen, reduces cellular oxidative stresses and inflammation, increases cellular immunity. Less hypoxia, less men, mayor recovery, less death”. , sostiene Cannellotto.
One of the criteria, specified Subbotina, to emphasize the treatment in hyperbaric chamber is the oxygen saturation chain at a rate of 93% for which, it is suggested, it is preferable not to lose time in initiating treatment with OHB.
“It is recommended for patients who are saturated with oxygen which determines a probable empeoramiento in his state, which can be fulfilling. The main purpose of the OHB treatment is to avoid the need to apply mechanical respiratory assistance, for this purpose it is necessary to treat the treatment temporarily, as soon as the oxygen saturation phase is observed “, concludes.
