概括
在高海拔地区睡眠期间定期呼吸不会对健康年轻男性的血液氧和产生负面影响. 基线氧气水平,而不是呼吸模式,主要决定在海拔高度的睡眠氧气和.
科学领域:
- 高海拔的生理学 高海拔的生理学
- 睡眠的药物 睡眠的药物
- 呼吸系统控制 呼吸系统控制
背景情况:
- 周期性呼吸 (PB) 是一个常见的现象,在高海拔地区睡眠期间,以交替的中央睡眠呼吸暂停和高通风为特征.
- 在高海拔地区的健康人群中,PB对睡眠血氧和 (SpO2) 的影响尚未完全理解,仍然是争论的主题.
- 了解这种关系对于评估高空暴露对睡眠质量和氧化的生理后果至关重要.
研究的目的:
- 为了评估周期性呼吸对睡眠血液氧和 (SpO2) 的影响,在模拟高空的健康年轻男性中.
- 为了比较同一个体的周期性呼吸 (PB) 与正常呼吸 (RB) 期间的平均 SpO2.
- 调查PB,呼吸暂停-呼吸暂停指数 (AHI),氧气脱度指数 (ODI) 和平均睡眠SPO2.2之间的相关性.
主要方法:
- 在36名健康的男性受试者身上,在3500米的模拟高度 (FiO2: 13%) 进行了多睡眠扫描.
- 参与者根据至少3分钟的PB与3分钟的RB相邻的存在来分类.
- 使用斯皮尔曼等级相关性和威尔科克森签名等级测试来分析SPO2,AHI,ODI和PB持续时间.
主要成果:
- 参与者平均43.9%的睡眠时间在PB中度过,AHI (77.3 / h) 和ODI (82.6 / h) 的中位数高.
- 在个人中,在PB和RB期间之间没有发现平均SpO2的显著差异 (P = 0.43).
- 平均睡眠SPO2与AHI (rs = -0.19),ODI (rs = -0.23) 或PB持续时间 (rs = -0.07) 没有显著的相关性.
结论:
- 定期呼吸本身似乎对模拟高海拔的年轻健康男性的平均睡眠血氧和没有不利影响.
- 清醒和睡眠之间强烈的相关性SpO2表明,基线氧和是睡眠在海拔高度氧化的主要决定因素,而不是呼吸模式.
- 这些发现表明,睡眠期间的呼吸模式可能对整体氧化不那么重要,而不是一个人在高海拔地区的基线生理状态.

Sleep Apnea
121
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

Insufficient Sleep and Sleep Deprivation
127
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

Special considerations while measuring oxygen saturation
529
Assessing respiratory rate concurrently with pulse measurement is fundamental to patient care, providing valuable insights into the patient's respiratory function. The normal breathing rate for an adult usually falls within a normal range of 12 to 20 breaths per minute. Abnormal respiratory rates can signal underlying health conditions or the need for immediate intervention.

Substance Use Disorders Affecting Sleep
155
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

Factors Affecting Respiration
4.4K
Respiration is a crucial physiological function involving exchanging oxygen (O2) and carbon dioxide (CO2) between an organism and its environment. Various factors can impact this essential process:

Sleep-Wake Cycles
1.2K
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).
