Chapter 3

Question 1

Pressure

Answer 1

Force per unit area: F=PxA, pwedeng static (constant) or dynamic measurement (using speech)

Question 2

Where can pressure be measured?

Answer 2

subglottic, supraglottic, transglottic

Question 3

subglottic

Answer 3

below the glottis so there’s more pressure: lungs, trachea, esophagus

Question 4

supraglottic

Answer 4

above the glottis so less pressure, intraoral pressure and nasal

Question 5

transglottic

Answer 5

across the glottis so from below to above; it measures the PTP

Question 6

what is PTP

Answer 6

phonation threshold pressure

Question 7

what methods for subglottic pressure?

Answer 7

invasive: tracheostomy, noninvasive methods

Question 8

non-invasive methods for subglottic pressure

Answer 8

U-tube manometer
spirometers
pneumotachograph
plethysmograph

Question 9

what is u-tube manometer

Answer 9

measures the effects of the force of a person’s expiration, measures air pressure differences

Question 10

what is a spirometer

Answer 10

measures respiratory volume/volume of air

Question 11

pneumotachograph

Answer 11

measures rate of airflow, kaya there’s a turbine spinning

Question 12

plethysmograph

Answer 12

measures changes in volume

Question 13

phonation threshold pressure

Answer 13

the pressure that you need to get your VF to start vibrating

Question 14

what measures transglottal pressure?

Answer 14

phonatory aerodynamic system

Question 15

phonatory aerodynamic system

Answer 15

measures pressure, airflow and other things related to speech and voice production measures max expiratory pressure (how much can they build up)

Question 16

what measures intraoral pressure during nonspeech

Answer 16

transducer, u-tube, spirometer, basta it measures expiratory pressure

Question 17

volume

Answer 17

always measured in liters or milliliters

Question 18

airflow

Answer 18

rate at which a volume of air moves through a plane, “volume velocity”

Question 19

Lung volumes (4)

Answer 19

tidal volume, inspiratory reserve volume, expiratory reserve volume, residual volume

Question 20

tidal volume (TV)

Answer 20

volume of air inhaled or volume of air exhaled during resting breathing

Question 21

inspiratory reserve volume (IRV)

Answer 21

volume inhaled after TV

Question 22

expiratory reserve volume (ERV)

Answer 22

volume of air you can forcefully exhale after TV

Question 23

residual volume (RV)

Answer 23

dead air, air left in lungs and airways after maximum exhalation

Question 24

Lung capacities (4)

Answer 24

total lung capacity TLC, vital capacity VC, inspiratory capacity IC, functional residual capacity FRC

Question 25

total lung capacity (TLC)

Answer 25

all volumes added together

Question 26

Vital Capacity (VC)

Answer 26

maximum useable air, amount of air that can be exhaled after maximum inhalation or vice versa (IRV + TV + ERV)

Question 27

Inspiratory Capacity (IC)

Answer 27

amount of air that can be inhaled after exhaling TV IRV + TV

Question 28

functional residual capacity

Answer 28

amount of air in the lungs and airway after tidal volume exhalation ERV + RV
