Perry C. Hanavan, Au.D.

2. Question What is the function the respiratory system? Absorb moisture
Breathing
Speech
All the above
B and C

3. Function
Life support
Exchange CO2 with O2
Speech
Energy source

4. Question
What is the thorax?
Mouth
Lungs
Chest
Abdomen
Throat

5. Question What is the function of the alveoli? Exchange N2 with O2
Exchange CO2 with O2
Exchange CO2 with H20
Exchange N2 with H2O2
None of these make sense?

6. Question Which lung do you think might be larger? Right Left Neither
Does it matter

7. Question What is the major muscle of respiration?
Internal intercostals
External intercostals
Neck muscles
Diaphragm
Internal respiratory muscle

12. Healthy vs. Unhealthy Lungs

13. Spirometer

14. Question
Can you exhale all the air in your lungs? True False

15. Lung Volumes & CapacitiesTV
IRV
ERV RV
Lung Capacities: VC
FRC
TLC

16. Question
The air you normally breath in and out is: VC TV
IRV
TLC

17. Question
All the air in you lungs is: VC TV
IRV
TLC

18. Lung Volumes and Vital Capacity

19. Speech Breathing More complex than quiet breathing
Coordination of breathing with linguistic utterances
Appropriate place to inhale
Appropriate amount of air to inhale & exhale
Prosodic variations

20. Question Average number of breaths per minute in an adult: 40-60 20-40
12-18
1-12
More than 60

21. Lung Developmental Changes

22. Lung Developmental Changes

23. Lung Developmental Changes

24. Life vs. Speech Breathing
Nose
Inhale 40% of time
Exhale 60% of time
10 % of vital capacity
Muscles of thorax and diaphragm
Speech
Mouth
Inhale 10% of time
Exhale 90% of time
20-25 % of vital capacity
Thoracic and abdominal muscles
exhale
inhale
exhale in

25. In speech breathing we inhale:
10 percent of the time
40 percent of the time
60 percent of the time
90 percent of the time
50 percent of the time

26. In life breathing we exhale:
10 percent of the time
60 percent of the time
40 percent of the time
90 percent of the time
50 percent of the time

27. Patterns

28. Measurement Devices Pneumatochograph used to measure airflow
Plethysmograph suit monitors the movements of both the abdomen and ribcage
Magnetometer is two coils of wire which generate an electromagnetic field

29. Diseases Parkinson's disease Cerebellar disease Cerebral palsy
Mechanical ventilation
Voice problems
Hearing problems
