Page 11: Using The Ear Wash System
Using the Ear Wash System Steps for Irrigation It is essential to follow the technique described in this section for using the Ear Wash System to minimize patient discomfort and avoid the risk of perforating the tympanic membrane. The factors determining the risk of perforating the tympanic membrane while irrigating the ear canal are the water pressure at the point of dis- charge and whether the discharged flow of water directly impinges on the tympanic membrane. -

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. - Page 14 5. It is important to aim the stream of water away from the longitu- dal axis of the ear canal and toward the ear canal walls by tilting and rotating the handle during the irrigation. Flood the ear with water. The suction return system will return the discharge away from the ear.

Page 22: Types Of Cerumen
Types of Cerumen Cerumen is the natural by-product of the ear canal. It lubricates the skin lining in the ear canal, acts as a water repellent, and entraps dust, hair fol- licles, and foreign bodies. Cerumen can take many different forms which affect the process and time to remove. -
Page 23: Anatomy And Physiology
Anatomy And Physiology • Cerumen is produced in the outer third of the ear canal and natu- rally moves to the outer ear as new tissue grows from the area around the tympanic membrane. • Normal cerumen routinely becomes a medical issue when it impedes the physicians ability to visualize the tympanic mem- brane. -
