1. Respiratory System Chapter 4 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

8. Basic Components Thoracic cavity Rib cage Spinal column Neck Muscles Pharynx Larynx Abdomen Muscles Viscera

9. Spinal Column Spinal Column Abnormal column

10. Thorax Gross Anatomy X-ray of thorax Pleura Breathing animations Respiratory muscles

11. Lungs Gross Anatomy Alveoli Alveoli Air Pressure Lung Model Breathing

12. Healthy vs. Unhealthy Lungs

13. Spirometer

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

15. Lung Volumes & Capacities

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 Life 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

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
