The method for measuring blood oxygen at a finger and the finger-clipped oximeter provided by the present invention can measure the finger temperature of the human body, consider the measured finger temperature as a reference of the measured blood oxygen content of the human body and present it ...
A blood oxygen partial pressure of less than 45 mmHg (or less than 55 mmHg with concurrent cor pulmonale) has been linked to increased mortality (Anon, 1980, 1981). These thresholds now guide the prescription of long-term oxygen therapy (Hardinge et al., 2015). Chronic hypercapnia, which ...
We provide accurate blood oxygen meters. Our finger oxygen sensor and pediatric pulse oximeter are prevalent because they are quality, intelligent, and Bluetooth-enabled.
