Lab 06 Spirometry

  1. 1. The Respiratory System & Spirometry Lab 6
  2. 2. Lab 6 Activities <ul><li>Identify parts of the respiratory system </li></ul><ul><ul><li>Respiratory tree, thoracic organs, and larynx models </li></ul></ul><ul><ul><li>Fresh lung (if available) </li></ul></ul><ul><li>Examine histology of the: </li></ul><ul><ul><li>Trachea </li></ul></ul><ul><ul><li>Lung </li></ul></ul><ul><li>Examine the operation of the lung model </li></ul><ul><li>Biopac L012-Lung-1:  Spirometry </li></ul><ul><ul><li>Measure lung volumes and capacities </li></ul></ul>
  3. 3. Respiratory System Structure <ul><li>Conduction zone: pathway for pulmonary ventilation </li></ul><ul><li>Respiratory zone: membrane for gas exchange  external respiration </li></ul><ul><li>Clinically, two parts: </li></ul><ul><ul><li>Upper respiratory tract </li></ul></ul><ul><ul><li>Lower respiratory tract </li></ul></ul>
  4. 4. Respiratory System Structure <ul><li>Histology reflects the different functions of the different parts of the system </li></ul><ul><li>Position in respiratory pathway determines cell type </li></ul><ul><li>non-keratinized stratified squamous </li></ul><ul><li>pseudostratified ciliated columnar </li></ul><ul><li>cuboidal ciliated </li></ul><ul><li>simple squamous / Type I Alveolar cells </li></ul>
  5. 6. Pseudostratified Columnar Epithelium Lamina Propria Hyaline Cartilage mucosa Submucosa
  6. 7. seudostratified epithelium = lamina propria ucous glands mooth muscle artilage
  7. 8. Gross Section Through Lung
  8. 9. Smoker’s Lungs Non-smoker 
  9. 10. Small Bronchiole
  10. 11. Lung Tissue slide Respiratory Bronchiole Alveolar Duct Alveoli Alveolar Sac
  11. 12. Capillaries in Alveolar Wall
  12. 13. Spirometry
  13. 14. SPIROMETRY – RESPIRATORY VOLUMES AND CAPACITIES Total Lung Capacity = Inspiratory Reserve Volume (IRV) + Tidal Volume (TV) + Expiratory Reserve Volume (ERV) + Residual Volume (RV) Vital Capacity = Inspiratory Reserve Volume (IRV) + Tidal Volume (TV) + Expiratory Reserve Volume (ERV) Inspiratory Capacity = Inspiratory Reserve Volume (IRV) + Tidal Volume (TV) Functional Residual Capacity = Expiratory Reserve Volume (ERV) + Residual Volume (RV)
  14. 15. Spirometry – Calibration Insert the calibration syringe/filter assembly into the side of the airflow transducer labeled &quot; Inlet .&quot;  Inlet Wait for 8 seconds of no air flow Inlet
  15. 16. Experimental Treatments <ul><li>4 normal breaths </li></ul><ul><li>Inhale as deeply as possible </li></ul><ul><li>Exhale to normal depth </li></ul><ul><li>3 normal breaths </li></ul><ul><li>Exhale as much as possible </li></ul><ul><li>3 normal breaths </li></ul><ul><li>Inhale as much as possible </li></ul><ul><li>Exhale as fast and completely as possible </li></ul><ul><li>4 normal breaths </li></ul>
  16. 17. BioPac Spirogram Example Data 3 regular breaths 3 regular breaths 3 regular breaths 1 strongest inhale 1 regular exhale 1 strongest inhale 1 strongest exhale 1 strongest exhale This part is in addition to what Biopac Lesson 12-Lung 1 prompts you to do! Do Data Analysis on the lower red Volume curve.
  17. 18. Summary of Class Data Link to Table
