This study aimed to assess the influence of elevated atmospheric pressure on the functions of attention of medical personnel working in hyperbaric chambers. We enrolled 15 participants who met the inclusion criteria. The test consisted of performing the same medical procedure under 2 conditions. For each of these test conditions, right eye movements were recorded using an oculograph. The obtained results revealed a relationship between elevated atmospheric pressure and the ability of medical personnel to focus.
To assess the influence of hyperbaric oxygen (HBO2) on visual attention in medical personnel during medical activities performed under normobaric (1 absolute atmosphere (1 ATA)) and hyperbaric (4 ATA) conditions inside a hyperbaric chamber.
Each participant had a valid license to act as a medical attendant during therapeutic hyperbaric sessions. Fifteen individuals, 10 men and 5 women aged between 28 and 65 years, participated in the study. The participants were asked to perform a medical procedure involving the preparation of a syringe with a drug administered by an infusion pump under 2 test conditions: 1 ATA corresponding to the atmospheric pressure on land, and 4 ATA corresponding to an underwater depth of 30 m. The order of test conditions was random. Both test conditions were performed inside a hyperbaric chamber.
The number of fixations in the area of interest (AOI) varied between stages (1, 2 and 3) and task conditions (1 ATA and 4 ATA), with lower values for the 4 ATA condition. Under 1 ATA, 30% of eye fixations were in the AOI, as compared to only 6% under 4 ATA.
The obtained results indicate that elevated atmospheric pressure has negative effects on the attention of medical personnel.
本研究旨在评估高压环境对在高压舱中工作的医务人员注意力功能的影响。我们纳入了 15 名符合纳入标准的参与者。该测试由在 2 种条件下执行相同的医疗程序组成。对于每种测试条件，使用眼动仪记录右眼运动。获得的结果显示了高压环境与医务人员聚焦能力之间的关系。
评估高压氧 (HBO2) 在高压舱内的常压（1 个大气压 (1 ATA)) 和高压（4 ATA) 条件下进行医疗活动时对医务人员视觉注意力的影响。
每位参与者均持有在治疗性高压疗程中担任医疗助理的有效许可证。研究共有 15 名参与者，其中 10 名男性，5 名女性，年龄在 28 至 65 岁之间。参与者被要求在 2 种测试条件下执行一项医疗程序，该程序涉及使用注射器准备药物，并通过输液泵给药：1 ATA 对应于陆地的大气压力，4 ATA 对应于水下 30 米的深度。测试条件的顺序是随机的。两种测试条件均在高压舱内进行。
在感兴趣区域（AOI）的注视次数在阶段（1、2 和 3）和任务条件（1 ATA 和 4 ATA）之间有所不同，4 ATA 条件下的注视次数较低。在 1 ATA 下，30%的眼注视在 AOI 中，而在 4 ATA 下只有 6%。
研究结果表明，高压环境对医务人员的注意力有负面影响。
