How do you measure the transglottal pressure - ANSWER-
pressure below-pressure above
What determines how much air flows through the larynx -
ANSWER-resistance
How does resistance determine how much air flows through the
larynx - ANSWER--higher resistance means lower flow;
-lower resistance means higher flow
How can we compute an estimate of laryngeal resistance -
ANSWER-Measuring the flow with a pnuemotach mask by
estimating the subglottic pressure during the closure for "p" when
you measure oral air pressure
What is the equation for Laryngeal airway resistance (Rlaw) -
ANSWER-Psub (cmH2O)/ Flow(L/s)
,2|Page
How do we measure exhaled volume - ANSWER-A Spirometer-
Helps calculate FEV1 (Forces exhibitory volume in one second)
How can we get direct measures of subglottal pressure -
ANSWER--Tracheal puncture
-Esophageal pressure
What is a tracheal puncture - ANSWER-doctor punctures hole into
trachea, below the larynx, and measures pressure with a
miniature pressure transducer
What is Esophageal Pressure - ANSWER-sends an esophageal
balloon down part way into the esophagus, and the sensor
measures the pressure on the shared wall of the trachea and
esophagus (posterior trachea meets with anterior esophagus)
How can you get a reasonable estimate of subglottal pressure? -
ANSWER-Measuring intraoral air pressure when the pressure in
, 3|Page
the mouth is the same as the pressure below the larynx, which is
when the person produces a "p" and vowel: PA PA PA
What is laryngeal devoicing gesture - ANSWER-When the vocal
folds are abducted which equalizes pressure (during the point of
lip closure when producing /p/)
how does the laryngeal devoicing gesture equalize pressure
between trachea and mouth - ANSWER-When vocal folds abduct,
the trachea and mouth are linked, which causes the pressure to
equalize very quickly (no pressure drop at larynx)
Why is there no pressure drop at the larynx during the laryngeal
devoicing gesture - ANSWER-because the /p/ is voiceless
What does a pneumotachograph do - ANSWER-device that
shows the speed at which air is flowing
What happens in a pneumotach - ANSWER-you pass the air flow
through a resistance
