- 在ECMO治疗中,很大一部分ARDS患者需要长时间的支持,因此需要准确的预后工具.
- 在ECMO期间识别不断变化的死亡率预测因子对于优化患者管理至关重要.
研究的目的:
- 在COVID-19 ARDS患者的ECMO支持的最初14天期间,调查死亡预测指标的动态变化.
- 确定ECMO治疗期间不同时间点与死亡率相关的特定因素.
- 为临床决策提供信息,提高ECMO依赖患者的生存率.
主要方法:
- 一项观察性研究分析了来自德国29个中心 (2020年1月 - 2021年7月) 接受ECMO的1137名COVID-19 ARDS患者的数据.
- 开发了多变量渐进后勤回归模型,使用ECMO前14天内每天的数据.
- 主要结局是重症监护室 (ICU) 的全因死亡率.
主要成果:

Acute Respiratory Failure-II
974
Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

Acute Respiratory Failure-V
407
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.

Acute Respiratory Failure-III
714
Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
1.7K
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Assessment of Ventilation II: Respiratory Depth and Rhythm
2.3K
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:

Respiratory Volumes
2.7K
Respiratory volumes are crucial metrics, meticulously measured to quantify the air exchanged in and out of the lungs during various phases of the breathing cycle. These precise measurements are vital for assessing lung function, diagnosing respiratory conditions, and monitoring overall respiratory health. Each parameter provides specific insights into the mechanics of breathing and the functional capacity of the lungs.
