the signal strength of SpO2 and also partially indicates the signal quality.
Above 1 is optimal;
Between 0.3 and 1 is acceptable;
Below 0.3 indicates low perfusion. If the PI is less than 0.3, the low perfusion
status is indicated (alternating with a question mark for SpO2 measurements),
indicating that the SpO2 measurements may be inaccurate. Reposition the
SpO2 sensor or find a better site. If low perfusion persists, choose another
method to measure oxygen saturation if possible.
(7) Pulse rate (PR) alarm off icon: pulse rate alarm is turned off.
(8) Pulse rate: the number of pulses detected per minute (from the pleth waveform)
10.2. Safety Information
WARNING:
Use only SpO2 sensors specified in this manual. Follow the SpO2 sensor’s
instructions for use and adhere to all warnings and cautions.
Before use, the operator needs to verify the compatibility between the monitor,
probe and cable. Otherwise, it may cause injury to the patient.
When a trend toward patient deoxygenation is indicated, analyze the blood
samples with a laboratory co-oximeter to completely understand the patient’s
condition.
Do not use SpO2 sensors during magnetic resonance imaging (MRI). Induced
current could potentially causes burns. The sensor may affect the MRI image,
and the MRI unit may affect the accuracy of the oximetry measurements.
Prolonged continuous monitoring may increase the risk of undesirable changes
in skin characteristics, such as irritation, reddening, blistering or burns.
Inspect the sensor site every 2 hours and move the sensor if the skin quality
changes. Change the application site every 4 hours. For patients with poor
peripheral blood circulation or sensitive skin, inspect the sensor site more
frequently.
Functional testers cannot be used to evaluate the accuracy of pulse oximetry
probes and pulse oximetry monitors.
