C. decrease in PVR
D. increase in SVR D. increase in SVR
This question is tricky. The first observation one must make is that the patient is putting out more
fluid than he is taking in. This will result in dehydration and a decrease in all hemodynamic
values including cardiac output. If cardiac output is decreased, systemic vascular resistance will
increase. One must know the formula for systemic vascular resistance in order to understand this.
Systemic vascular resistance is determined by subtracting CVP from MAP and dividing it by
cardiac output. If cardiac output is decreased then the final SVR number will increase.
Which of the following would result in an increase in pulmonary capillary wedge pressure?
A. decrease in pulmonary vascular resistance (PVR)
B. mitral valve stenosis
C. dehydration
D. cor pulmonale B. mitral valve stenosis
During a difficult intubation, the emergency room physician requests an endotracheal tube that is
smaller than recommended for the patient's height and ideal body weight. As a result, the
respiratory therapist should anticipate
