In hyperbaric oxygen therapy (HBOT), a patient is exposed to pure oxygen in a chamber. While HBOT is a long-standing and well-established treatment for a wide variety of medical conditions, one of the main complications is middle ear barotrauma (MEB), which can lead to complaints of ear discomfort, stuffiness or fullness in the ear, and difficulties in equalizing ear pressure. The aim of this study is to evaluate the efficacy of self-acupressure in preventing and reducing the degree of MEB associated with HBOT.
This is a prospective nonrandomized controlled study. A sample of 152 participants will be assigned to 2 groups in a 1:1 ratio. The participants in the control group will receive conventional Valsalva and Toynbee maneuvers, while those in the experimental group will be given additional self-acupressure therapy. The acupoints used will be TE17 (Yifeng), TE21 (Ermen), SI19 (Tinggong), and GB2 (Tinghui). The Modified Teed Classification, symptoms of MEB, and overall ear discomfort levels will be assessed. Data will be analyzed using the Chi-Squared test or t test.
This study aims to evaluate the efficacy of self-acupressure for preventing and reducing the degree of MEB associated with HBOT.

高压氧治疗（HBOT）中，患者在舱内吸入纯氧。虽然 HBOT 是一种历史悠久、广泛应用于多种医疗状况的治疗方法，但其中一个主要的并发症是中耳气压伤（MEB），可导致耳部不适、耳闷或耳胀以及耳压平衡困难等症状。本研究旨在评估自我耳压按摩在预防和减轻 HBOT 相关 MEB 程度方面的疗效。
这是一项前瞻性非随机对照研究。将 152 名参与者按照 1:1 的比例分配到 2 组。对照组将接受常规瓦尔萨尔瓦和托恩比手法，实验组将在此基础上进行额外的自我耳压按摩治疗。使用的穴位为耳门（TE17）、听宫（TE21）、听宫（SI19）和听会（GB2）。采用改良 Teed 分类、MEB 症状和整体耳部不适程度进行评估。数据将使用卡方检验或 t 检验进行分析。
本研究旨在评估自我耳压按摩预防和减轻 HBOT 相关 MEB 程度的疗效。
