Patient Monitor Using SpO2

Circulation at Application Site
• Wrapping the tape too tightly, or using supplemental tape, can cause venous
pulsations that could potentially lead to inaccurate saturation measure-
ments.
• Avoid wrapping the adhesive too tightly and do not use additional tape to
secure the sensor. High positive intrathoracic airway pressures, valsalva
maneuvers, or other consequences of impaired venous return may also
cause venous pulsations.
• Only use adhesive wraps recommended by Hewlett-Packard.
• Avoid placing the SpO
2
sensor on any extremity with an arterial catheter,
blood pressure cuff, or intravascular venous infusion line.
Connecting the Sensor to the Instrument
When you have applied the sensor to the patient, plug the disposable and
semi-disposable sensors into the connector cable and plug this cable into the
SpO
2
socket on the lower right of the HP CodeMaster 100. Plug the HP
M1190A sensor directly into the SpO
2
socket of the HP CodeMaster 100. The
plug is keyed and is color-coded blue to distinguish it from the white ECG
socket. See Figure 9-3.
