Patient Safety

Pulse oximetry is a non-invasive method of monitoring the oxygen saturation of arterial
blood. Pulse oximeters display oxygen saturation of functional hemoglobin and
therefore the accuracy may be interfered with by carboxyhemoglobin or other
dysfunctional hemoglobins present in significant concentrations. Oxygen saturation
monitoring is intended to be used in a variety of clinical situations, including, but not
limited to respiratory therapy, anesthesia, intensive care, and emergency.
The Model 509 Pulse Oximetry Interface Module SpO
Patient leakage current flowing from the instrument to ground is limited to less than 50
µA at 120 VAC, 60 Hz. Patient isolation is tested at 2500 VAC rms at 60 Hz.
For maximum patient and operator safety, the following are recommended:
• Failure of Operation: If the module fails to respond as described, do not use it
until the situation has been corrected by qualified personnel.
• Keep the Model 509 and its accessories clean.
• Do not operate the Model 509 when it is wet due to spills or condensation.
• Do not operate the Model 509 if it appears to have been dropped or damaged.
• Connect the Model 509 only to Novametrix approved power supply.
• Connect the external supply only to a grounded hospital grade outlet. It should
be connected to the same electrical circuit as the equipment it is used with.
Outlets on the same electrical circuit can be identified by the hospital's
engineering department.
• Care should be exercised to assure continued peripheral perfusion distal to the
SpO sensor site after application.

CANNOT be processed when the cuff is inflated. Attach the sensor to the limb
opposite to the site used for the blood pressure cuff.
• Do NOT wrap the sensor tape around the limb so tightly that circulation is
restricted. Inspect the site often for adequate circulation - at least once every four
hours. When applying sensors take not of the patient's physiological condition.
For example, burn patients may exhibit more sensitivity to heat and pressure and
therefore additional consideration such as more frequent site checks may be
appropriate.

modules only.
