12. Clinical Measurement

Question 1

Draw runaway
washout
wahsin curve

What are their formula

examples of physiological processes

Whats essential feature of expon process - eg runaway

Answer 1

pg 259

runaway y= e^Kx

• depol nerve cell - threshold reach
  bacterial growth

y - e^-kx
preoxygnation

y = (1-e-kx)
washot N

Rate change proportional amount present at any instant

Question 2

Invasive pressure measurement

What steps calibrate catheter transducer systems - use measuring arterial pressure?

Answer 2

1 Static calibration
- zero tducer
CHeck + adjust gain
Check time stability

Dynamic calibration
