TELEMETRY TRANSMITTER (96281)
ECG
AND SP O
2
• This pulse oximeter measures functional saturation, which is
essentially the percentage of hemoglobin that can transport
oxygen (oxyhemoglobin). Pulse oximeters do not detect
significant amounts of dysfunctional hemoglobins, such as
carboxyhemoglobin or methemoglobin, which cannot carry
oxygen. Saturation measurements from pulse oximeters
cannot be directly compared to measurements from a
laboratory co-oximeter. Co-oximeters provide a fractional
saturation (SaO
2
) value by measuring each type of
hemoglobin individually. This fractional value is the ratio of
oxygenated hemoglobin to all measured (oxygenated and
dysfunctional) hemoglobins.
• A pulse oximeter SpO
2
measurement may not match the
saturation calculated from a blood gas partial pressure of
oxygen (PO
2
). The most likely reason is that the calculated
saturation value was not corrected to reflect the effects of
variables that alter the relationship of PO
2
and pH. Such
variables can include temperature, the partial pressure of
carbon dioxide (PCO
2
), 2,3-DPG, and fetal hemoglobin.
Refer to your hospital’s protocols for specific instructions.
Warnings and Cautions for SpO
2
This section includes warnings and cautions specifically related to
SpO
2
. Also included are cautionary disclosures that apply to
electrodes and leadwires, defibrillators (including automatic
implantable cardiac defibrillators), pacemakers, electrosurgical
activity, several physiological parameters, or to the monitoring
system itself.
• A pulse oximeter should be considered an early warning
device and should NOT be used as an apnea monitor. If a
trend toward patient deoxygenation is indicated, blood
samples should be analyzed by a laboratory co-oximeter
to completely understand the patient's condition.
• Pulse rate measurement is based on the optical detection
of a peripheral flow pulse and therefore may not detect
certain arrhythmias. The pulse oximeter should not be
used as a replacement or substitute for ECG-based
arrhythmia analysis.
• Carboxyhemoglobin may erroneously increase readings.
The level of increase is approximately equal to the amount
of carboxyhemoglobin present. Dyes or any substance
containing dyes that change usual arterial pigmentation
may cause erroneous readings.
