背景情况:
- 静脉静脉外体膜氧化 (VV-ECMO) 的持续性低氧化症可能是静脉转移的结果.
- 心率 (HR) 控制是一种提高ECMO流量与心力输出 (CO) 比率的策略,并减少CO升高的患者的分流.
研究的目的:
- 为了评估HR控制疗法的疗效和安全性,在VV-ECMO患者中增加了CO.
- 评估HR控制对血液动力学和氧化参数的影响.
主要方法:
- 在VV-ECMO患者 (2019年6月至2023年6月) 接受HR控制剂的10天内进行回顾性研究.
- 在HR控制开始后72小时内分析血液动力学,氧化,呼吸器和ECMO参数.
- 评价不良事件,如低血压和心肌梗塞.
主要成果:
- 包括39名患者;常见的策略是输注埃斯莫洛尔,然后服用口服β-阻断剂.
- HR控制导致HR和CO的减少,但氧化率没有显著变化.
- 副作用是最小的,只有两例低血压需要干预.
结论:
- 在VV-ECMO患者中,HR控制疗法耐受性良好,有效降低HR和CO.
- 目前的数据表明,HR控制不能改善这个人群的氧化.

Physiological Control of Respiration
3.7K
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...

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...

Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure
330
Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
1.0K
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,...
