Abstract: Recent studies investigated the feasibility of using an RGB camera to estimate peripheral oxygen saturation (SpO2), i.e., “Ratio of Ratios” by red (R) and green (G) channels and calibration ...

Objectives COVID-19 causes lung parenchymal and endothelial damage that lead to hypoxic acute respiratory failure (hARF). The influence of hARF severity on patients’ outcomes is still poorly ...

PaO2/FiO2（PF）比值被广泛用于评估重症患者的呼吸衰竭情况，以指导通气策略和预后判断。然而，由于该指标需要侵入性动脉 ...

Abstract: A binary search method for fast identification of the time-constant in first order systems is proposed. The unimodality of the Root Mean Square Error (RMSE ...

If your patient is adequately preoxygenated, you’re far more likely to do harm by rushing an intubation attempt to get it done in less than 30 seconds than you are likely to cause a hypoxic state. It ...

The following is a summary of “Clinical Performance of Spo 2 /Fio 2 and Pao 2 /Fio 2 Ratio in Mechanically Ventilated Acute Respiratory Distress Syndrome Patients: A Retrospective Study,” published in ...

The pulse-oximetric peripheral oxygen saturation to a fraction of inspired oxygen (SpO 2 /FiO 2) ratio has been suggested as an additional hypoxemia criterion in the new global acute respiratory ...

本研究针对急性呼吸窘迫综合征(ARDS)新全球定义中提出的SpO2/FiO2比值替代PaO2/FiO2的临床可行性问题，通过分析三大ICU数据库708 ...

当我们谈及呼吸衰竭，其实更关注的是呼吸衰竭的病理生理机制以及基于此机制最终产生的结果。无论是通气功能障碍，还是换气功能障碍，都会导致氧气无法正常在体内运输，进而出现缺氧状态。通过氧输送（DO 2 ）公式【DO 2 =CaO 2 ×CO×10，CaO 2 =Hb×1.34×SaO 2 +PaO ...

单位：中日医院呼吸中心 国家呼吸医学中心 呼吸与危重症医学科 氧合血红蛋白并不能直接被机体所利用，需要氧分子从血红蛋白上解离出来，才能够进入机体的组织细胞。我们在临床上也利用了血红蛋白的物理化学特性。氧离曲线从起始段到快速升支直至平台 ...
