High Static Admittance
High Static Admittance (high
peak height) indicates possibility
of:
l
Tympanic membrane
abnormalities
l
Ossicular disruption
NOTE: “HIGH Ya” will print out
in place of gradient (GR) value
when admittance exceeds
1.5 mmho (see OVER, pg. 11).
Volume (+ 200 Vea) Too Large
Excessively large volume in
presence of flat tympanogram
indicates possibility of:
l
Perforated tympanic membrane
l
Patent tympanostomy tube
NOTE: If volume exceeds
2cc,
a
LEAK ( = F ) symbol will appear;
above
2.5cc,
an OPEN
(=I
)
symbol will appear.
Negative Tympanometric Peak
Pressure
Negative TPP indicates
eustachian tube dysfunction as
a result of:
l
