Recommended prepping strategy:
1. Remove and set aside sensor(s) and wash sensor site(s) with soap and water.
Do not touch sticky side of the sensor or allow it to contact any cloth surface. Use a
gauze sponge and mild soap to clean the skin, and be sure to remove all traces of soap.
2. Prep site with NuPrep
®
gel
Put a tiny drop of gel on the corner of a sponge gauze. Hold skin taut and scrub the site
gently. Use a damp cloth or the reverse side of the gauze sponge to remove all the gel.
3. Replace the sensor(s) and check impedance
If readings range from 12-20 kOhms, gently hold the sensors to the skin for a minute to
allow them to adhere, then wait a few minutes. Impedances may decrease. If readings
remain >12 kOhms, continue prepping.
4. Lift sensor(s) and apply a drop of saline
Gently lift a corner of each sensor and place a small drop of saline on the site, which
may add enough moisture to decrease impedances.
5. Discard sensors, re-prep with NuPrep
®
gel, and try new sensors
At this point, you may wish to leave the infant to re-settle before resuming.
Natus supplies provide the low impedances necessary for ALGO screening. If you have
persistent impedance problems, ensure that you are using Natus supplies, then contact Natus
technical service or your authorized service representative for assistance.
