这项随机试验调查了运输期间重症患者的适应性每分钟通风 (AMV). 结果将确定AMV是否是传统机械通风的安全替代品,改善患者的治疗结果.
科学领域:
- 关键护理医学 关键护理医学
- 呼吸系统疗法 呼吸系统疗法
- 临床试验 临床试验
背景情况:
- 病情危急,机械通风患者的医院内运输带来了显著的生理风险.
- 适应式分钟通风 (AMV) 是一个闭环系统,旨在自动保持目标分钟通风.
- 在医院内运输期间AMV的有效性和安全性尚未评估.
研究的目的:
- 评估AMV的安全性和有效性与在医院内运输期间的传统通风策略相比.
- 评估AMV在运输环境中保持目标分钟通风的性能.
- 解决在运输过程中为重症患者提供机械通风策略的证据缺口.
主要方法:
- 一个单中心,开放标签,随机控制的非劣等性试验,涉及50名成年患者.
- 患者被随机分配 (1:1) 接受AMV或运输前通风模式.
- 主要终点:从运输前到运输后,动脉二氧化碳压力 (PaCO2) 的变化.
主要成果:
- 主要结果将是PaCO2.2的变化.
- 二次结果包括氧化指数 (PaO2 / FiO2) 的变化,气道压力峰值,动态遵守和快速浅呼吸指数.
- 将进行治疗意图和每项方案分析,通过多重归算处理缺失数据.
结论:
- 这是第一个随机研究,在重症患者的医院内运输过程中评估AMV.
- 该研究旨在提供关于AMV作为运输通风替代品的安全性和有效性的强有力的证据.
- 这些发现可能会为临床实践提供信息,并改善在危急疾病运输期间的患者护理.

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
Critical Guidelines for Assessing Ventilation:
Mechanical Ventilation II: Invasive Ventilation
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...

Ventilatory Modes
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...
Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
Equipment
The equipment necessary for this procedure includes:
