Carbon Dioxide Sensor to be Optimized for Medical ...

Respiration rate and exhaled carbon dioxide (CO2) concentrations are known to be key measures in the evaluation of patient health trends in both routine healthcare and emergency healthcare. However routine and reliable measurement of respiration rate is notoriously difficult to do. It is prone to false readings, outside influences and is therefore not considered reliable. Previous attempts have included the use …
