Week 13

Question 1

What does a SpiroPet measure?

Answer 1

vital capacity in cubic centimeters (cc) of air

Compared to normative data based on age and sex

Question 2

What are norms for maximum phonation time?

Answer 2

Children - about 10 sec
Adults - about 20 seconds
Females - about 25.7 seconds
Males - about 34.6 seconds

Question 3

What does a short MPT suggest?

Answer 3

Respiratory problem
Lack of checking action
Glottal insuffiency
VPI
Errors in data collection

Question 4

What does an excessively long MPT suggest?

Answer 4

Singer
Pressed phonation
Hyperadduction of VF
Error in data collection

Question 5

What is the phonation quotient?

Answer 5

Vital capacity divided by MPT

Question 6

What are the phonation qoutient norms?

Answer 6

269 cc/sec in adult men

233 cc/sec in adult women

Question 7

What does a high PQ suggest?

Answer 7

Lack of checking action
Glottal insuffiency
VPI
Error in data collection

Question 8

What does a low PQ suggest?

Answer 8

Singer
Pressed phonation
Hyperadduction of VF
Error in data collection

Question 9

Why is /z/ longer than /s/?

Answer 9

/s/ has one place of constriction

/z/ has the same, but VF are vibrating so glottis is opening and closing

Question 10

Norms for s and z separately

Answer 10

Children - s 9 seconds, z is 11 sec

Adults - s 16 sec, z is 19 sec

Question 11

Short s and z suggest?

Answer 11

Respiratory problems
Lack of checking action
Errors in data collection

Question 12

Excessively long s and z suggests?

Answer 12

Singer
Athlete
Error in data

Question 13

Norms for s/z ratio?

Answer 13

Normal - less than 1 (.7 to .99)

Question 14

Greater than 1 s/z ratio

Answer 14

s is normal
z is leaky

Glottal insufficiency
VPI
Error in data

Question 15

Less that .7 s/z ration

Answer 15

Increased medial compression
Excessive stiffness of VF
Constriction in vocal tract
Inappropriately loud voice
Pressed phonation
Errors in data collection

Question 16

What are norms for quiet breathing per minute

Answer 16

Adult - 12 to 16

Children 6-12 years - 12-20

Question 17

Can you rely on algorithms?

Answer 17

no. they are unreliable when F0 variability exceeds 6% per cycle

Question 18

The mean pitch range for males and females on a sustained vowel is ______ octaves

Answer 18

two to three

Question 19

Mean male F0

Answer 19

130 Hz

Question 20

Mean female F0

Answer 20

220 Hz

Question 21

Frequency perterbation

Answer 21

jitter

Question 22

Amplitude perturbation

Answer 22

shimmer

Question 23

Harmonic to noise ratio

Answer 23

Collect with sustained vowels

Higher=greater periodic sound (preference)
Lower=greater aperiodic, ROUGHNESS

Question 24

What are the discharge categories?

Answer 24

Clinically normal outcome
Max gain
ADLs
Self discharge

Question 25

Clinically normal outcome

Answer 25

Habitually uses appropriate manner of production to all types of voice

Appropriate voice stamina to meet needs

Dynamic loudness, pitch, and timing flexibility

Question 26

Maximum gain

Answer 26

Patient’s needs met
Pt and clinician agree rehab is maximized
Voice will never be normal
No more hypothesis to test
Pt does not practice and refuses to change Bx like drugs

Question 27

ADL discharge

Answer 27

Pt and clinician agree pt voice will allow communication for daily needs

Question 28

self discharge

Answer 28

Pt does not attend or come back
Moves away
Cannot afford
