Effectiveness of HBOT in Severe Patients with COVID-19
We learned that HBOT doesn’t act directly on the virus but the strong effectiveness of oxygen therapy directly stops the continuous aggravation of hypoxemia that may be
caused by lung hiopathology, especially the accumulation of oxygen deficits in the state of systemic hypoxia, and the secondary damage of important oxygen consumption
tissues and organs. It not only can make the body maintain a relatively good functional state, but also can make the body have a good state when fighting the virus.
HBOT for severe patients with COVID-19 is similar to the conventional treatment of usual cases in the past. Doctors can choose specific and familíar treatment options for their patients. According to our experience, we recommend the following treatment options as an alternative:
1.For patients with a blood oxygen saturation below 70 percent before entering the oxygen chamber or with a long course of persistent hypoxemia, a higher pressure is recommended for their once-daily HBoT, and it should not be less than 2.0 ATA. Steady pressure time is 90 min each time, 2 times/ day when necessary
2.For patients with a blood oxygen saturation between 70-80 percent before entering the oxygen chamber. 2.0 ATA and 90 min in steady pressure is recommended.2 times/ day , when necessary.
3.For patients with a blood oxygen saturation between 80-90 percent before entering the oxygen chamber. 1.6-2.0 ATA and 60 min in steady pressure is recommended.
4.For patients with a blood oxygen saturation higher than 90 percent before entering the oxygen chamber. 1.6 ATA and 60 min in steady pressure is recommended.
5. Discontinuation of HBOT may be considered if the minimum level of blood oxygen saturation monitoring in the ward is higher than 95 percent for two consecutive days.
Commonly, five times of HBOT can significantly improve hypoxemia, butitis advisable for patients who are affordable to complete a full course of treatment.
HBOT for COVID-19
HBOT is not a specific medicine, but as a safe and effective oxygen therapy method,
timely intervention can significantly reduce the morbidity and mor -tality of severe and critical illness,
which can improve treatment efficiencysignificantly.
Use of Monoplace Hyperbaric Chamber or Portable Hyperbaric Chamber
In institutions that do not have a regular hyperbaric oxygen chamber, you can choose a suitable monoplace oxygen chamber or a portable hyperbaric chamber used for diving
decompression sickness treatment. The chambers are required to be at least 1.6ATA pre-ssure and breathe pure oxygen from mask. Patients should be monitored under goci”
medical staff, and should be with good capabilities of gas disinfection and purification. 6m (1.6ATA) is the depth of unlimited no-decompression diving, and can be quickly
decompressed (within 3min) to atmospheric pressure when needed, ensure that emergency medical care can be quickly obtained when there are changes in patient ‘s medical moni -toring or
clinical manifestation changes. （via Dr. Zhou Xiaolin）Thanks for her efforts!
