Introduction
SD32+
System
channel display menu option
This option displays the waveform of a channel’s signal on the LCD screen. The Channel Display
option works with the following channel types: Airflow, Chest, Abdomen, Nasal Cannula,
Airflow Sum, EtCO
2
, PES, Pulse Amplitude, Pleth, and Other. The signal is automatically scaled
to fit the 128 by 68 pixel display screen. The waveform “wraps around” the display so that when
it reaches the far right side of the display drawing resumes on the left overwriting the previously
drawn signal. The channel label initially appears in the background, but is eventually overwritten
by the signal as it is drawn. Scroll through the channels using the up
S
and down
T
menu
control buttons.
Note: The
SD32+
does not store collection data, therefore, the LCD screen can only display
signal waveforms during a
Sandman
Elite
Collection.
3.5. integrated pulse oximeter
The integrated pulse oximeter calculates oxygen saturation (SpO
2
) and heart rate (HR) data
collected using an approved sensor. The
Sandman Elite
software receives this data and displays it
on the computer monitor.
The pulse oximeter’s accuracy depends on the sensor used with the device. For some sensors, the
accuracy of neonatal data may differ from that of adult data.
The following conditions can also affect data accuracy.
•
Improper sensor application
•
Excessive patient movement
•
Sensor placement on an extremity that has a blood pressure cuff, arterial catheter, or
intravascular line
•
Intravascular dye injections
•
Significant concentrations of dysfunctional hemoglobin, such as carboxyhemoglobin and
methemoglobin in the patient’s blood
•
Sensor temperature (maintain between 28°C and 42°C for best operation)
•
External illumination greater than 5000 lumens/m
2
(typical office lighting)
•
Venous pulsation
•
High-frequency electrical noise, including electrosurgical equipment and defibrillators
•
Interference from magnetic resonance imaging (MRI) procedures
