Question
The Guyton-Coleman model, gives the arterial pressure response (Pa) in mmHg to a small change in fluid intake (Fin) in ml/min. Select all that are true (Multiple-Choice). a) The impulse response best models the increase in pressure due to a constant intake of liquid. b) The step response best models the increase in pressure due to a constant intake of liquid. c) The impulse response best models the increase in pressure due to a sudden, and quick, intake of liquid. d) The step response best models the increase in pressure due to a sudden, quick, and intake of liquid.
Explanation / Answer
The third (c) statement is correct. Impulse response is reversible proportional to fluid intake volume at sudden. The Guyton-Coleman used the rate of fluid intake at 0.5 ml/min.
According the formula TFs = PA x/ FINs
Where FINs is the impulse fuction, PA is arterial blood pressure, and T f is the transfer function.
