Other Sensors
A wide variety of reusable and disposable pulse oximetry sensors are available for use with the
Welch Allyn Spot Vital Signs. These sensors expand the utility of the pulse oximetry component
of the device.
Warning:
Use only Nellcor brand SpO» sensors and accessories with Welch Allyn's Spot Vital
Signs configured with the Nellcor pulse oximetry module.
Taking an SpO Measurement
To take an SpO2 measurement:
1.
Properly attach the appropriate sensor to the patient.
2.
The pulse signal bar graph illuminates, indicating the relative strength and quality of the
patient's pulses at the sensor site. The sensor takes approximately 10 seconds to determine
the initial SpO2% value and pulse rate. When the initial values are determined, they are
shown in the SpO> display and the Pulse Rate display, respectively.
3.
The SpO2%
and pulse rate are updated approximately every second. The Spot Vital Signs
monitors a patient's SpO? for up to 10 minutes. After 10 minutes, a C9 error code is displayed.
This error code means that the 10-minute time limit has been exceeded.
4.
Removing the SpO2 sensor from the patient ends the measurement period, and the pulse
signal bar graph blanks.
