If a waveform on a ventilator does not return to baseline, what is occurring?
  1. The flow is inadequate.
  2. The respiratory rate is inadequate.
  3. The patient has air trapping.
  4. The waveform is not correct.
Explanation
Answer: C-If the waveform on a ventilator does not return to baseline the patient has air trapping.

Not all ventilators have waveforms and, in such cases, the respiratory therapist would see a failure to return to exhaled value gauges to determine any issues with ventilation.
