Slow compression during hyperbaric oxygen therapy (HBOT) significantly reduces middle-ear barotrauma compared to standard compression. This safer HBOT method is recommended for patient care.

Area of Science:

  • Hyperbaric medicine
  • Otolaryngology
  • Patient safety

Background:

  • Hyperbaric oxygen therapy (HBOT) involves breathing pure oxygen in a pressurized chamber.
  • Middle-ear barotrauma is a common complication of HBOT, causing discomfort and potential injury.
  • Current HBOT protocols utilize standard compression, with variable rates of barotrauma incidence.

Purpose of the Study:

  • To compare the incidence of middle-ear barotrauma between standard and slow compression techniques in HBOT.
  • To evaluate if the slow compression technique meets predefined safety standards for barotrauma incidence.

Main Methods:

  • A prospective clinical audit included 42 patients undergoing HBOT via standard or slow compression.
  • Pre- and post-treatment otoscopy, tympanometry, audiometry, and subjective ear complaints were assessed.

  • Data were compared between compression groups and against established standards.

    • Main Results:

    • The slow compression technique resulted in significantly lower incidence of middle-ear barotrauma (p < 0.05).
    • Standard compression failed to meet the target incidence of less than 40% barotrauma.
    • The slow compression method demonstrated superior safety in preventing ear barotrauma.

    Conclusions:

    • Slow compression HBOT is a safe and effective alternative to standard compression.
    • The slow compression method significantly reduces the risk of middle-ear barotrauma.
    • This technique offers improved patient outcomes in hyperbaric oxygen therapy.
