Fully stabilized Sensor output 4-20mA Resistor 240 Ohms
Voltage V ADC 10bit ( ) Closer to 197 (~0.,96V), closer to 0PPM

COCl2 cross sensitivity check
6.5% of tidal volume is CO2 5,000/1,000,000=0.5% So… rise in COCl2 sensor makes sense

BEpatch: carotid detection (w/ filtering)
Output: is it noise or is it vibrations from the body? (carotid pulse might have a BCG-like shape)
