Is capnography universally required at the EMR level?

• A. Yes; it is mandatory in all EMS.
• B. It measures blood sugar.
• C. No; it depends on equipment and local scope; many EMRs do not require it.
• D. It assesses pain.

Answer: (C)

Capnography is the ongoing measurement of exhaled CO2 and the waveform it produces, which helps you gauge ventilation, confirm airway placement, and monitor how well a patient is ventilating. Whether it’s required at the EMR level isn’t fixed everywhere because it depends on what equipment a service has and what the local scope of practice allows. Some EMS systems include capnography as standard and mandate its use for airway management and monitoring, while others don’t require it at the EMR level due to equipment limits or different protocols. That variability is why the best choice is that it depends on equipment and local scope; many EMRs do not require it. It isn’t about blood sugar or pain assessment.
