What is Ohm’s Law

An Emergency Medical Responder provides emergency care:

A) only if the injuries are life-threatening. B) every time an emergency happens. C) until the patient arrives at the hospital. D) until EMTs or paramedics take over care.

A low ETCO2 reading, as measured by capnography, would MOST likely be observed if:

A. there is an absence or decrease in the level of CO2 in the lungs. B. a patient in cardiac arrest is receiving high-quality CPR. C. an endotracheal (ET) tube is correctly placed in the trachea. D. the cells produce large amounts of CO2 and return it to the lungs.
