Therefore, you should make arrangements to obtain replacement or loan equipment within a very short time from the salesperson, a neighboring hospital, university, audiologist, or school district. If OAE technology is being used, the single most important factor in reducing refer rates is to make sure screeners understand how to achieve appropriate probe fit. Although this is relatively easy to learn, it may not be immediately obvious to screeners and usually has to be taught. A screening program whose personnel have not mastered the techniques of good probe fit will generally have refer rates at the time of hospital discharge two to four times higher than a program where screeners have mastered probe-fitting techniques. For AABR Procedures, Screen When Myogenic Activity Is Low AABR screeners have artifact rejection systems built in so data are not included in the average when myogenic activity is high.
Myogenic activity is caused by muscle tension.
If babies are tense, wiggly, or restless, myogenic activity will be higher, and it will substantially increase the screening time. It may even result in more babies who need to be brought back for rescreening or diagnostic procedures because a pass could not be obtained. Thus, it is best to do screening when babies are relaxed, happy, well fed, and, if possible, asleep.
