Dr Martin J Tobin discusses health disparities related to pulse oximeter accuracy and the need for improvement to make health care equitable.

In this paper, we have proposed a novel design for recording aortic pulse wave using electrical impedance technique. Unlike conventional ECG, photo-plethysmography, and pulse oximetry measurements, ...

Pulse oxygen saturation is an important physiological parameter for monitoring oxygen content and respiratory function. It is very inconvenient that the pulse oximeter in the hospital use transmission ...
