Non-invasive estimation of arterial blood pH using exhaled CO/CO2 analyser, microwave radar and infrared thermography for patients after massive haemorrhage.
In order to conduct non-contact estimation of arterial blood pH after massive haemorrhage, we calculated the arterial pH based on linear-regression analysis of exhaled gas concentrations (CO and CO2) and vital signs (heart rate, respiratory rate, and surface temperature) measured using non-contact methods in hypovolemic animals.
