概括

在支气管镜检查过程中,超旋喷气通风 (SJV) 没有防止肺通风和氧化率下降,但维持了足够的 SpO2. 术前SJV改善了这些指标,与鼻喷气氧化相比,将通风转移到腹部.

科学领域:

呼吸系统医学
肺病学
关键的护理

背景情况:

在灵活的支气管镜检查过程中,使用超支气管透气 (SJV) 来增强氧化.
它对整体肺透气的影响尚不清楚.
胸部电阻断层扫描 (EIT) 提供实时呼吸监测.

研究的目的:

使用EIT评估SJV在灵活支气管镜检查期间对肺透气和氧化的影响.
为了比较透气分布与SJV与微鼻喷气 (WNJ) 氧化.

主要方法:

一项前性试点研究,涉及接受灵活支气管镜检查的患者.
胸部EIT在不同时间点测量了末端呼气阻抗 (EELI) 的变化.
主要结局:SJV (T2) 期间的 ΔEELI 与支气管检查 (T3) 期间的 ΔEELI. 二次结局包括SPO2和通风分布 (ROIventral).

主要成果:

总共包括27名患者,5名患者经历过渡性脱.
SJV 没有防止 ΔEELI 和 SpO2 从 T2- T3 降低 (p<0.001).
与WNJ (T1) 相比,SJV (T2) 的 ΔEELI 和 SpO2 (p<0. 001) 增加,腹肺通风率显著增加 (ROI Ventral: 43. 7% 至 60. 4%,p<0. 001).

结论:

在支气管检查过程中,尽管对肺呼吸有负面影响,但SJV保持了足够的SpO2.
与WNJ相比,bronchoscopy前的SJV改善了通风和氧化,但改变了通风向腹部区域的分布.

Assessment 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:

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Mechanical Ventilation II: Invasive Ventilation

Mechanical Ventilation II: Invasive Ventilation

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...
