OXITEST PLUS 7 OPERATING MANUAL
3.6 Selecting a Heart Rate
Oxitest Plus 7
provides a pulse repetition rate of 20 to 250 beats per minute (bpm), with six preset
values of 30, 60, 90, 120, 180 and 240 bpm. To select a new preset value, press the key labelled
Heart Rate on the front panel. The Heart Rate indicator, in the middle of the second line of the
LCD screen, will change to indicate the selected rate, as shown.
N-200 NO SIGNAL
97%
60 $ BPM
100%
For values between the preset rates, use the
•
and
–
keys associated with the Heart Rate key.
The Heart Rate can be changed in increments of 1 bpm over the full range of 20 - 250 bpm. The
•
and
–
keys may be held down to change the rate continuously.
The Heart Rate value on power up will be the one retained from the last test performed.
3.7 Selecting a Pulse Amplitude
Oxitest Plus 7
provides pulse amplitude settings from 0 to 100 percent, with four preset values of
100, 30, 10 and 5%. The pulse amplitude control provides a means of simulating various levels of
tissue perfusion or peripheral pulse "strengths". An
Oxitest Plus 7
pulse amplitude of 100%
corresponds to a normal adult pulse in the index finger. A pulse amplitude of 5% simulates poor
distal circulation or a very weak peripheral pulse, and a pulse amplitude of zero simulates no distal
blood flow.
To select a new preset value, press the key labelled Pulse Amp on the front panel. The Pulse
Amplitude indicator, at the lower right of the LCD screen, will change to indicate the selected
percentage value, as shown below.
N-200 NO SIGNAL
97% 60 BPM
100%
For values between the preset amplitudes, use the
•
and
–
keys associated with the Pulse Amp
key. The Pulse Amplitude can be changed in increments of 1% over the full range of 0-100 %.
The
•
and
–
keys may be held down to change the pulse amplitude continuously.
The Pulse Amplitude value on power up will be the one retained from the last test performed.
