Flashcards in Faithful Reproduction Of Physiological Events Deck (9):
0

Artifact

False signals superimposed on true signal

1

Calibration

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

2

Catheter whip

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

3

Damping

Loss of the energy and vibrations within the monitoring system

4

Dynamic response

Systems ability to measure physiological pressure changes

5

Fidelity

Indication of systems capacity to faithfully reproduce the physiological event

6

Natural frequency

Frequency at which the system vibrates when stimulated by pulsation signals

7

Overshoot/ undershoot

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

8

Ringing

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