Management of Respiratory Impairment Flashcards
4 parameters of speech performance
- air pressure
- lung volume
- flow
- respiratory shape
Normal alveolar pressure is ___________ cm H20.
Goal is:
5-10 cm H20
Goal: Generate steady alveolar pressure during an utterance, with slight variations
The ________ the lung volume, the _______ the recoil force and the greater the alveolar pressure from recoil forces alone
Larger
Larger
Perceptual speech correlate for lung volume level
Breath group duration
For speech lung volume level is: \_\_\_\_\_\_\_\_% vital capatity \_\_\_\_\_\_\_\_ seconds in duration \_\_\_\_\_\_\_\_\_syllables \_\_\_\_\_\_\_ cc is average lung volume expenditure
10-20%
5 seconds
15 syllables
50 cc
When upright, gravity contributes to _______ forces of the rib cage and _________ forces of the abdomen
Expiratory
Inspiratory
For a given lung volume, greater air pressures are generated in the ___________ position
Supine - gravity contributes to expiratory force of both the rib cage and abdomen
Normal speech takes _______% of vital capacity in seated position
60-35%
Ratio of inhalation to exhalation during speech ______.
Inhale at ___ % vital capacity
Take a breath at syntactic junctures ____ of the time
1:6
35%
74%
Poor valving compensated for by:
- decrease length of breath groups
- soft speech
- inhalation at a greater lung volume
- speak into expiratory reserve
VF hyperadduction causing increased laryngeal resistance compensated for by:
increased alveolar pressure
Incoordination is compensated for by:
excess and equal stress
GOAL: Consistent alveolar pressure
Blow bottle training
Sustained phonation
Biofeedback methods
Postural adjustments for:
people who struggle to develop/maintain adequate air pressure valves in the seated position
upright - helps inhalation pulling abdominal contents down
supine - helps exhalation, pushing diaphragm into thoracic cavity
Spastic dysarthria postural adjustment
Positioning to reduce excessive muscle tone
