What Researchers Did
Researchers studied 210 elderly patients with ischaemic heart disease and heart failure to see how hyperbaric oxygen therapy (HBOT) affected their heart function, blood gases, and acid-base balance.
What They Found
They found that HBOT helped normalize cardiac output and made the heart's work more efficient by speeding up heart rate and improving the balance between cardiac output and peripheral resistance. However, HBOT also caused shifts towards acidosis in blood gas and acid-base balance. The study also noted that HBOT improved oxygen supply to tissues by stimulating peripheral circulation.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
A limitation is that the abstract does not specify the hyperbaric oxygen therapy protocol used, such as pressure or number of sessions, and the study is quite old.
