Irrigation
1. Initially, you may cover the patient with a cloth drape to eliminate
splashing onto his or her clothes. Once the technique of sealing the
ear canal is mastered, this is not necessary.
2. Begin to run water through the unit by turning the hot and cold
water on full power. Adjust the water exiting the bottom of the
chamber until it feels close to body temperature.
NOTE: Reducing the hot or cold water will impact the pressure.
3. Check the temperature of the irrigating
water by looking at the thermal sensor
while depressing the water flow actuator.
If the thermal sensor is blue, the irrigating
water is not warm enough. If the thermal
sensor white, the water temperature is at
least 90
°
F and the procedure may begin.
You must depress the actuator on
the handle for the temperature sen-
sor to function correctly.
4. To irrigate the ear, grasp the patient’s
pinna. Pull gently back to straighten a
child’s ear canal or up and back for an
adult. While maintaining tension on the
pinna, insert the tip of the handle into the
ear to create a seal. Tilt the handle so the
ear tip is directed away from the longitu-
dal axis of the ear canal and toward any
point on the wall of the ear canal.
Squeeze the actuator on the handle and
slowly rotate the tip. By adjusting how
much force you push on the actuator,
some control over the flow rate is
attained.
If the water is too cold, the patient may become experience vertigo
and/or light-headedness. Please verify that the thermal indicator is
white before proceeding with the irrigation
