まとめ
圧力調節換気 (PRVC) は,圧力調節換気 (PCV) と比較して,急性呼吸不全の新生児の酸素化を改善しました. PRVCの換気により,呼吸道圧力が低下しましたが,肺動態は2つのモードで似ています.
科学分野:
- 新生児の集中治療
- 呼吸器医学
- 機械的な換気
背景:
- 急性呼吸器不全は新生児重症治療室 (NICU) の大きな課題です.
- 呼吸器不全の新生児の治療には 機械呼吸が不可欠です
- 従来の圧力制御換気 (PCV) は広く使用されていますが,圧力調節ボリューム制御 (PRVC) のような新しいモードは潜在的な利点を提供しています.
研究 の 目的:
- 急性呼吸不全の新生児におけるPRVCとPCVの換気法の有効性を比較する.
- PRVCとPCVが酸素と肺動力学に与える影響を評価する.
- PCVと比較してPRVCが酸素供給と肺動態を改善するという仮説を検証する.
主な方法:
- 新生児集中治療室で 呼吸不全を患っている60人の新生児を対象に 準実験的研究を行いました
- ランダム化されていない2つのグループ:PRVC (n=30) とPCV (n=30)
- 酸素濃度,肺動力学,動脈血ガス,呼吸器のパラメータの評価は,出血から1時間,呼吸から24時間.
主要な成果:
- PRVCグループは,PCVと比較して,1時間および24時間で,SPO2,PaO2,P/ F比が有意に高かった.
- 吸入酸素 (FiO2) の必要量と呼吸速度の低下は,PRVCグループで24時間後に観察された.
- PRVCは高潮量を維持し,ピークインスピレーション圧力と平均気道圧が一貫して低く,肺の順守と運転圧は有意な違いを示さなかった.
結論:
- PRVC換気は,急性呼吸器不全の新生児にPCVと比較して優れた酸素供給を提供します.
- PRVCの換気は平均気道圧の低下と関連しており,呼吸器による肺損傷を減少させる可能性がある.
- PRVCとPCVは,この新生児集団の肺動力学に類似した効果を示しています.

Physiological Control of Respiration
3.2K
Introduction
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...

Mechanical Ventilation II: Invasive Ventilation
253
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...

Ventilatory Modes
423
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...

Mechanical Ventilation III: Noninvasive Ventilation
224
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.

Mechanical Ventilation I: Indication and Settings
922
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...

Acute Respiratory Failure-V
203
The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.
