Faithful Reproduction Of Physiological Events

Question 0

Calibration

Answer 0

Standardization of measuring instrument: the checking of a measuring instrument against an accurate standard to determine any deviation and correct for errors

Question 1

Artifact

Answer 1

False signals superimposed on true signal

Question 2

Catheter whip

Answer 2

Movement of catheter tip within the blood vessel in response to pulsation flow

Question 3

Damping

Answer 3

Loss of the energy and vibrations within the monitoring system

Question 4

Dynamic response

Answer 4

Systems ability to measure physiological pressure changes

Question 5

Fidelity

Answer 5

Indication of systems capacity to faithfully reproduce the physiological event

Question 6

Natural frequency

Answer 6

Frequency at which the system vibrates when stimulated by pulsation signals

Question 7

Overshoot/ undershoot

Answer 7

System vibration that occurs when the patients pressure wave contains a component frequency equal to the systems natural frequency

Question 8

Ringing

Answer 8

Multiple small spikes on the waveform due to inadequate dynamic response characteristics
