Theory for using HBO is that people with the flu had a higher mortality at higher elevations.closed in 1930 because of the lack of scientific evidence indicating that such treatment alleviated disease.
The structure, erected in 1928, was 6 stories high and 64 feet in diameter.The hospital could reach 3 atmospheres of pressure.
Theory for using HBO is that people with the flu had a higher mortality at higher elevations.closed in 1930 because of the lack of scientific evidence indicating that such treatment alleviated disease.
The work of Paul Bert, who demonstrated the toxic effects of oxygen (producing grand mal seizures), as well as the work of J. Lorrain-Smith, who demonstrated pulmonary oxygen toxicity, were used with Navy divers.
Increasing the proportion of oxygen in the inhaled gas mixture increases its partial pressureAir at sea level is 21% O2HBO2 treatments use FiO2 100%
By increasing ambient pressure, more oxygen can be dissolved in the plasma
Each gram of Hb can carry 1.34 ml of oxygen when it is fully saturated.
which is more than enough to meet resting cellular requirements without any contribution from hemoglobin.and can also provide tissue oxygenation in the setting of impaired Hb conc. or function.
HBO is particularly effective against anaerobes and facilitates the oxygen-dependent peroxidase system by which leukocytes kill bacteria.Clostridium perfringens alpha toxin synthesis inhibitedTemporary inhibition of neutrophil Beta 2 integrin adhesion
stimulates an adaptive increase in superoxide dismutase (SOD), one of the body's principal, internally produced antioxidants and free radical scavengers
causes a rebound arterial dilation after HBOT, resulting in an increased blood vessel diameter greater than when therapy began, improving blood flow to compromised organs.
This method does not treat DCS, (AGE), or (CO) poisoning. It may also cause a tourniquet-like effect.
