[Variations in pulse rate and arterial pressure during hyperbaric oxygenation]

Area of Science:

• Physiology
• Cardiovascular Medicine
• Oxygen Therapy

Context:

• Hyperbaric oxygenation (HBOT) is a medical treatment involving exposure to pure oxygen at elevated atmospheric pressure.
• Assessing the physiological impact of HBOT on vital signs is crucial for patient safety and treatment optimization.
• Previous research has explored HBOT's effects, but specific cardiovascular responses require continued investigation.

Purpose:

• To evaluate the influence of hyperbaric oxygenation on pulse rate and blood pressure in patients undergoing treatment.
• To determine if observed variations in cardiovascular parameters are statistically significant across different HBOT pressure levels.
• To correlate physiological responses with the pressures utilized during hyperbaric oxygenation therapy.

Summary:

• Forty-five patients undergoing at least five hyperbaric oxygenation sessions were monitored.
• Mean pulse rate and blood pressure (pre- and post-treatment) were analyzed to assess HBOT's impact.
• No statistically significant variations in pulse rate or blood pressure were found at the employed HBOT dosages, though responses correlated with pressure.

Impact:

• Findings suggest that current HBOT protocols, within the studied dosages, do not induce significant adverse cardiovascular changes.
• The correlation between physiological responses and pressure highlights the importance of pressure titration in HBOT.
• This study contributes to understanding the safety profile of hyperbaric oxygenation concerning hemodynamic stability.
