AI Technical Summary
In the existing technology, blood gas measurement devices are usually large in size and have high power requirements, making them unportable. Furthermore, conventional methods require connection to auxiliary computing devices, which limits their application outside of clinical settings.
By employing miniaturized wireless devices and utilizing a charge-to-digital converter (CDC) architecture, and through time-domain dual lifetime reference calculations, the luminescence response of a carbon dioxide-sensitive membrane is used to achieve accurate measurement of transdermal carbon dioxide, reducing interference from confounding factors.
It achieves high-precision measurement of carbon dioxide on the skin surface, reduces the size and power requirements of the device, makes the device portable and suitable for remote monitoring of patients' respiratory status, and increases the likelihood of patients being discharged early.
