概括
已建立的氧气吸收峰值 (VO2max) 预测方程对于患有多发性硬化症 (PwMS) 的人来说是不准确的. 这项研究开发了针对多发性硬化症妇女可靠的VO2max评估的调整模型,改进了心肺健康评估.
科学领域:
- 运动生理学 运动生理学
- 神经学 神经学
- 生物医学工程 生物医学工程
背景情况:
- 已建立的峰值氧气摄入量 (VO2max) 预测方程,为健康人群开发,对多发性硬化症患者 (PwMS) 等患者群体的适用性有限.
- PwMS通常存在心肺呼吸系统和神经肌肉系统的损害,需要开发定制的VO2max预测模型.
- 本研究通过评估现有配方和创建调整模型,解决了对患有多发性硬化症 (MS) 的女性准确VO2max估计的需求.
研究的目的:
- 评估四种常见的VO2max预测方程的有效性,可靠性和准确性,用于MS的轻度至中度残疾女性.
- 为患有多发性硬化症的妇女开发调整的VO2max预测方程,并纳入与多发性硬化症有关的功能障碍.
- 为PwMS提供实用工具,在临床和日常环境中评估心肺呼吸能力.
主要方法:
- 51名患有复发性复发性多发性硬化症 (RRMS) 的女性使用循环人体测量进行了增量心肺运动测试 (CPET).
- 通过开放电路螺旋计进行了气体交换分析.
- 四个已建立的VO2max预测方程 (ACSM,Storer's,Uth's,Myers') 与测量的VO2max进行了评估,随后进行了回归分析,以确定调整模型的预测因子.
主要成果:
- 现有的方程显示出显著的偏差:ACSM和Storer低估了VO2max,而Uth和Myers高估了它.
- 回归分析确定了调整模型的关键预测因素,包括工作率/体重,年龄,体重,峰值瓦特,心率比率和扩展残疾状态量表 (EDSS).
- 经过调整的模型被开发出来,以提高MS患者VO2max估计的准确性.
结论:
- 现有的VO2max预测方程需要对患有MS的女性进行特定的调整,以考虑功能障碍.
- 拟议的调整模型为各种运动强度提供可靠的心肺健康评估,适合临床和一般使用.
- 这项研究支持了"从长椅到床边"的方法,使得在不同的环境中对PwMS的VO2max评估成为可能.

The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like...

Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
