Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Maneuver group
Patients in the experimental group will receive detailed training and guidance on pressure equalization techniques and barotrauma prevention measures before undergoing treatment in a hyperbaric chamber. The specific maneuvers to be implemented are outlined below:
Toynbee Maneuver: This maneuver involves swallowing with both the mouth and nose closed, thereby reducing the pressure in the nasopharynx and tympanic cavity.
Unilateral Passive Valsalva Maneuver: This technique involves occluding one external nasal valve while performing a Valsalva maneuver on the opposite side.
These maneuvers will be performed continuously during the compression phase of the hyperbaric chamber, every 30 minutes after reaching the desired pressurization level, and continuously during the decompression phase.
Maneuver group
These maneuvers for Eustachian tube opening will be performed continuously during the compression phase of the hyperbaric chamber, every 30 minutes after reaching the desired pressurization level, and continuously during the decompression phase.
Standard treatment
Patients will receive the standard instructions for the hyperbaric chamber without specific guidance on performing equalization maneuvers.
