sensors and accessories with Welch
Allyn’s Spot Vital Signs.
The finger clip pulse oximeter sensor is designed for spot check measurements of pediatric and
adult patients.
Insert the patient’s finger (preferably left or right index finger) completely into the sensor. The
thumb is specifically not recommended for use with the finger clip sensor.
Note: If blood pressure measurement is occurring simultaneously, insure that the finger clip SpO
2
sensor is attached to the limb opposite
the limb with the blood pressure cuff.
Note: Check sensor sites periodically to determine circulation, sensor positioning, and skin sensitivity.

Taking an SpO
2
Measurement
To take an SpO
2
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 SpO
2
% value and pulse rate. When the initial values are determined, they are
shown in the SpO
2
display and the Pulse Rate display respectively.
3. The SpO
2
% and pulse rate are updated approximately every second. The Spot Vital Signs
monitors a patient’s SpO
2
for up to 10 minutes. After 10 minutes, a C9 error code is displayed.
this error code means that the 10 minute time has been exceeded.
4. If you remove the SpO
2
sensor from the patient, the measurement period ends and the pulse
signal bar graph blanks. The SpO
2
display flashes for 8 seconds, then displays the last SpO
2
reading for 2 minutes (unless another measurement is active). The device then goes into
standby mode. You may recall the last patient reading by pressing the Mode button.
Note: If the SpO
2
sensor is detached or falls off a patient, the SpO
2
reading flashes for 8 seconds. If the
sensor is not reattached to the patient in 8 seconds a beep sounds, notifying you that the SpO
2
measurement has ended.
