Hyperbaric oxygen therapy exerts powerful beneficial effects on the human body and is typically prescribed at higher pressures in many hospitals and wound care centers. Lower pressure protocols have advanced this procedure to many other conditions, particularly chronic conditions, reporting positive outcomes. However, there are a small number of patients who cannot even tolerate these lower pressures and are therefore looking at very low pressures. The question occurs, “Are there benefits to very low hyperbaric pressures?” This study may help them feel a little more comfortable, as they show that even slight pressures were able to cause positive changes in blood vessels. This is consistent with many other research publications that have demonstrated giving slight pressure can have positive benefits <view study> Read Less
