Answer

The monitor software version

Answer

The monitor battery level

Answer

The room temperature

Question 5

What parameter does capnography monitor and what is the normal end-tidal CO2 (EtCO2) range for a healthy adult?

Accepted Answer

Exhaled carbon dioxide concentration, 35-45 mmHg

Answer

Blood oxygen levels, 95-100%

Answer

Inhaled oxygen concentration, 21%

Answer

Respiratory muscle effort, 10-20 cmH2O

Question 6

What is the difference between invasive and non-invasive blood pressure monitoring, and when is invasive monitoring preferred?

Accepted Answer

Invasive uses an arterial catheter and transducer for continuous beat-to-beat monitoring in hemodynamically unstable patients

Answer

Invasive is less accurate but faster

Answer

Invasive uses a larger cuff

Answer

There is no clinical difference
