大多数重症Covid-19患者死于多器官功能衰竭和/或心脏骤停(SCA),这是由于共病的内皮功能障碍疾病,这些疾病可能因传统的机械辅助装置而加重。更糟糕的是,机械呼吸器阻止呼吸泵执行其作为内皮剪切应力(ESS)的潜在发生器的关键功能,该内皮剪切应力(ESS)从出生起控制微循环和血液动力学。这项工作的目的是把我们的经验,ESS增强和肺血管阻力(PVR)的管理作为一个潜在的治疗方案,在急性呼吸窘迫综合征(ARDS)。我们提出了一种非侵入性装置,由胸部和脑下室组成,将用低压气动发生器(0.1-0.5 bar)以交变频率(20/40 bpm)脉动。氧气供应,鼻胃管,或不考虑气管内导管。
Most critically ill Covid-19 patients succumb to multiple organ failure and/or sudden cardiac arrest (SCA) as a result of comorbid endothelial dysfunction disorders which had probably aggravated by conventional mechanical assist devices. Even worse, mechanical ventilators prevent the respiratory pump from performing its crucial function as a potential generator of endothelial shear stress (ESS) which controls microcirculation and hemodynamics since birth. The purpose of this work is to bring our experience with ESS enhancement and pulmonary vascular resistance (PVR) management as a potential therapeutic solution in acute respiratory distress syndrome (ARDS). We propose a non-invasive device composed of thoracic and infradiaphragmatic compartments that will be pulsated in an alternating frequency (20/40 bpm) with low-pressure pneumatic generator (0.1–0.5 bar). Oxygen supply, nasogastric with, or without endotracheal tubes are considered.
