概括
在接受单肺通风 (OLV) 的婴儿中,在麻醉后出现时使用100%氧气的正极端呼气压 (PEEP) 改善了氧化和减少了透. 这种策略没有增加风险,这表明小儿胸腔镜手术患者的潜在益处.
科学领域:
- 儿科麻醉学 儿科麻醉学
- 胸部外科手术 胸部外科手术
- 呼吸系统生理学 呼吸系统生理学
背景情况:
- 一个肺通风 (OLV) 经常用于儿科胸腔镜手术.
- 在OLV后从麻醉中出现,可能导致低氧化和消毒.
- 支气管阻塞剂用于促进OLV,但它们的去除可能会影响肺空气.
研究的目的:
- 评估在麻醉后出现时,结合100%氧气的阳性终端呼气压 (PEEP) 对阿特莱克塔斯的作用.
- 为了比较接受PEEP的婴儿在胸腔镜叶切除术期间除掉支气管阻塞剂后的标准护理与接受PEEP的婴儿的结果.
主要方法:
- 一项随机对照研究,涉及138名接受胸腔镜叶切除术的婴儿.
- 组A (n=69) 没有接受PEEP,FiO2为0.6-0.8.8.
- 组B (n=69) 接受了PEEP的5-6cmH2O与100%的氧气直到输出.
主要成果:
- 与A组相比,B组表现出显著改善的氧化指数和PaO2水平.
- 在B组,Atelectasis评分 (肺部超声波和胸部放射) 显著较低.
- 在B组 (20.3%) 与A组 (66.7%) 相比,低氧化症 (SpO2 <90%) 的患病率显著降低.
- 在B组中,输出管的时间和氧气的持续时间较短.
结论:

Mechanical Ventilation II: Invasive Ventilation
258
Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
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...

Mechanical Ventilation III: Noninvasive Ventilation
231
Noninvasive positive-pressure ventilation (NIPPV), continuous positive airway pressure (CPAP), and bilevel positive airway pressure (BiPAP) are essential methods in respiratory care. These ventilation techniques offer unique benefits for patients with various respiratory conditions, providing adequate support without requiring intubation. Let's explore how each method is crucial in improving patient outcomes and enhancing respiratory therapy.

Ventilatory Modes
452
Mechanical ventilators are life-saving devices that support or replace spontaneous breathing. They deliver breaths to patients through varying methods known as ventilator modes. Understanding these modes is critical for healthcare providers managing patients with respiratory failure.
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...

Pulmonary Cycle: Exhalation
1.8K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Mechanical Ventilation I: Indication and Settings
990
Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...
