Answer:
The reason the colorimetric CO2 detector does not turn yellow is that the baby is not exhaling CO2.
Explanation:
The colorimetric CO2 detector is a device that shows the existence of exhaled CO2.
The colorimetric CO2 detector has a pH-sensitive filter that changes color when it comes into contact with the CO2 exhaled by the patient.
When the patient is not exhaling CO2, the pH filter turns purple.
When the patient is exhaling CO2, the pH filter turns yellow
