本研究针对COVID-19诱发的急性呼吸窘迫综合征(ARDS)患者氧合障碍难题，通过随机对照试验探讨俯卧位对氧饱和度(SpO2)、动脉血氧饱和度(SaO2)、氧分压(PaO2)及呼吸频率的即时影响。结果显示30分钟俯卧位干预可显著改善氧合参数并降低呼吸频率，为重症护理提供了 ...

Conclusions: SpO2 and PR measurements may be inaccurate across all skin pigmentation groups, breaching U.S. Food and Drug Administration guidance and industry standard thresholds. Pulse oximeters ...

An ABG test checks how well your lungs and kidneys work by measuring oxygen and carbon dioxide in your blood. This test helps doctors know if your body has an acid-base balance issue and if treatment ...

A pulse oximeter measures blood oxygen levels at home and in healthcare settings. Abnormally low readings on a pulse oximeter might require medical care, especially if they are below 92%. Skin color ...

To take a pulse oximetry reading, turn on the device, place it on your fingertip, sit still, and wait for a stable reading. Normal oxygen saturation levels range from 95% to 100%; levels below 92% may ...
