背景情况:
- 过早出生的新生儿有腹膜功能障碍,导致通风效率低下和能量消耗增加.
- 在早产婴儿中,隔膜的平坦,弱,水平位置会损害肺机械.
研究的目的:
- 为了比较在辅助控制 (AC-PC) 和呼吸压力控制与体积保证 (VG) 通风下早产新生儿的胸部膨胀.
- 评估与这些通风模式相关的二次通风和自主结果.
主要方法:
- 一个交叉临床试验测量了胸部扩张通过感应囊造影.
- 气管 (峰值压力,分钟体积,遵守,阻力) 和自主 (心率,呼吸率,SpO2) 参数被记录下来.
- 测量时间为0,30分钟和60分钟,模式之间有30分钟的洗时间.
主要成果:
- 在所有时间点 (T0,T30,T60) 中,胸部膨胀在VG模式下显著更高.
- 周围氧和 (SpO2) 在VG模式下更高,特别是在T30.

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
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:

01:23Mechanical Ventilation III: Noninvasive Ventilation
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.
