Warnings!
•Check the device, sensors and probes to make
sure that there is no visible damage that may
affect user’s safety or measurement performance
with regard to sensors and clips. It is
recommended that the device should be inspected
once a week. When there is obvious damage, stop
using the device.
•The device should be carefully monitored if in
use when ambient temperature exceeds 98.6°F,
37ºC. Injury may occur due to overheating of the
sensor
•Discomfort may occur if the oximeter is used on
the same finger for an extended period of time,
especially for poor microcirculation patients.
•It is recommended that the oximeter should not
be applied to the same location for longer than 2
hours. If any abnormal condition is found, please
change the position of oximeter.
•Avoid placing the device on the same limb which
is wrapped with a cuff for blood pressure
measurement or during venous infusion.
•DO NOT clip this device on edema or tender
tissue.
II

User Manual for the Hopkins®Newborn & Mom Pulse Ox
•The light (the infrared light is invisible) emitted
by the device is harmful to the eyes, so service
technicians and patients should not stare at the
light.
•Please follow local regulations when disposing of
the oximeter, its accessories and batteries.
Warnings forAdult Fingertip Operation
•The finger should be inserted into the sensor in the
correct position.
•The patient’s finger should remain still during
measurement.
•Do not put wet finger directly into sensor.
•Do not let anything block the emitting light from
device.
•Vigorous exercise and electrosurgical device
interference may affect the measuring accuracy.
•Using enamel or other makeup on the nail may
affect the accuracy of measurement; long
fingernails may cause failure of measurement or
inaccurate measurement results.
•Keep the oximeter away from dust, vibration,
corrosive substances, explosive materials, high
temperature and moisture.
III

User Manual for the Hopkins®Newborn & Mom Pulse Ox
Important!
•Existence of high intensive light sources, such as
fluorescence light, ruby lamp, infrared heater or
strong sunshine, etc. may cause inaccurate
measurement. Please put an opaque cover on the
sensor or change the patient’s location.
•If the first reading shows unstable waveform, the
measurement may be false. In order to obtain a
more accurate measurement, simply wait for the
waveform to stabilize or remove the sensor and
take a second reading.

Operation
3.1 Direct Measurement
1. Open the clip as shown in Figure 3.
Figure 3 Put finger into the Oximeter
2. Put finger into the rubber cushions of the clip (make
sure the finger is in the correct position with OLED
display facing up), and then clip the finger.
3. The device will power on automatically in 2 seconds,
and start to display software version number.
4. The user can read the values and view the waveform
on the display screen as seen in figures 4A-4F
below.
Shift parameter display between PR and PI during
measurement:
Press the Display Key, the screen will tilt 90º. At this time,
PR will shift to PI automatically (as shown in 4B). When
shown as 4B, the display will shift to 4C automatically
after 20 seconds without operation. Press the key again
and the screen will change to another position (as shown
4

in 4D). Shifting parameter display between PR and PI is
under the condition of the screen tilting to a side, as
shown in 4B and 4E. After 20 seconds without operation,
the PI will automatically shift to PR, as shown in 4C and
4F.

Important! Note: When the Hopkins®Y-Probe Sensor
is connected properly, the built-in finger clip sensor
will be disabled. The measurement is detected from the
external SpO2probe.
2. The finger should be inserted into the SpO2probe in
the correct position with the light emitting diode
“LED” on top of the measuring location.
3. The oximeter will power on automatically 2 seconds

measurement.
3.5 ProperApplication of Hopkins Y-Probe
Your Newborn and Mom Pulse OX Kit, Model:
#716266 comes with a package of 10 hook-and-loop
non-stick sensor wraps which are provided to secure
the Hopkins®Adjustable Y-Probe Sensor for accurate
monitoring of pulse and blood oxygen levels in the
patient. The recommended application site for infant
and pediatric patients is on the finger, foot, or hand.
The recommended application for adult patients is on
the finger.
Using the Hopkins®Y-Probe wrap (#592012)
A. FingerApplication Adult or Pediatric Use:
1. Choose a well perfused (large blood supply) site
that fits in the sensor. The index finger is
recommended for adult patients.
2. Remove nail polish or artificial fingernails.
3. Place the sensor to the patient with the light
source (LED) to the fingernail. The photo-detector
(PD) sensor should be placed on the opposite side so
both sensors are lined up and facing each other.
11

User Manual for the Hopkins®Newborn & Mom Pulse Ox
4. Secure the sensor with the Hopkins® Adjustable
Y-Probe Sensor Latex Free Belt and tighten gently.
5. Apply a Hopkins® Y-Probe wrap on top to
prevent ambient light interference. A secure wrap with
the probe sensor centered in the middle of it will
minimize any effects from ambient light sources.
Other wraps can be used to secure lead wires to
minimize the movement of the sensor itself.
IMPORTANT! LED Sensors are light sensitive. Use
Hopkins® Y-Probe wrap on top of the belt to better
secure the probe.
B. Infant Hand or Foot:
1. Attach the sensor to a well perfused fleshy
portion of the infant’s hand or foot.
2. Place the sensor to the patient with the light

source (LED) on the top of the hand or foot.The
photo-detector (PD) sensor should be placed on the
opposite side so both sensors are lined up and facing
each other.
4. Secure the sensor with the Hopkins® Adjustable
Y-Probe Sensor Latex Free Belt and tighten gently.
5. Apply a Hopkins® Y-Probe wrap on top to

the probe sensor centered in the middle of it will
minimize any effects from ambient light sources.
Other wraps can be used to secure lead wires to
minimize the movement of the sensor itself.
IMPORTANT! LED Sensors are light sensitive. Use
Hopkins® Y-Probe wrap on top of the Adjustable
Y-Probe Sensor with belt to better secure the probe.
