1 Lab 6 THE RESPIRATORY SYSTEM & SPIROMETRY

2 LAB 6 ACTIVITIES Identify parts of the respiratory system Respiratory tree, thoracic organs, and larynx models Fresh lung (if available) Examine histology of the: Trachea Lung Examine the operation of the lung model Biopac L012-Lung-1: Spirometry Measure lung volumes and capacities

3 RESPIRATORY SYSTEM STRUCTURE 1.Conduction zone: pathway for pulmonary ventilation 2.Respiratory zone: membrane for gas exchange external respiration Clinically, two parts: Upper respiratory tract Lower respiratory tract

4 RESPIRATORY SYSTEM STRUCTURE Histology reflects the different functions of the different parts of the system Position in respiratory pathway determines cell type non-keratinized stratified squamous pseudostratified ciliated columnar cuboidal ciliated simple squamous / Type I Alveolar cells simple squamous / Type I Alveolar cells

6 PSEUDOSTRATIFIED COLUMNAR EPITHELIUM Lamina Propria Hyaline Cartilage mucosa Submucosa

7 seudostratified epithelium = lamina propria ucous glands mooth muscle artilage

8 GROSS SECTION THROUGH LUNG

9 SMOKERS LUNGS Non-smoker

10 SMALL BRONCHIOLE

11 LUNG TISSUE SLIDE Respiratory Bronchiole Alveolar Duct Alveoli Alveolar Sac

12 CAPILLARIES IN ALVEOLAR WALL

13 SPIROMETRY

14 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) SPIROMETRY – RESPIRATORY VOLUMES AND CAPACITIES

15 SPIROMETRY: CALIBRATION Insert the calibration syringe/filter assembly into the side of the airflow transducer labeled "Inlet." Inlet Follow pop up window instructions Wait for 8 seconds of no air flow, Then do your 5 syringe cycles. Inlet

16 EXPERIMENTAL TREATMENTS 1.4 normal breaths 2.Inhale as deeply as possible 3.Exhale to normal depth 4.3 normal breaths 5.Exhale as much as possible 6.3 normal breaths 7.Inhale as much as possible 8.Exhale as fast and completely as possible 9.4 normal breaths

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 This part is in addition to what Biopac Lesson 12-Lung 1 prompts you to do! If you get a negative value, just put the absolute value.

18 BIOPAC: DATA ANALYSIS P-P Measures Tidal Volume Record in Table 1 on page Lab 6-19

19 BIOPAC: DATA ANALYSIS P-P Measures Inspiratory Capacity Record in Table 1 on page Lab 6-19

20 BIOPAC: DATA ANALYSIS Delta Measures Inspiratory Reserve Volume Record in Table 1 on page Lab 6-19 Use similar methods to determine: Expiratory Reserve Volume Vital Capacity

21 BIOPAC: DATA ANALYSIS To measure FEV 1 Highlight from peak of max inhale to the point where Delta T is 1 second P-P Measures FEV 1 Record in Table 1 on page Lab 6-19 Use similar methods to determine FEV 2 and FEV 3 :

22 BIOPAC: DATA ANALYSIS P-P Measures FVC Record in Table 1 on page Lab 6-19

23 SUMMARY OF CLASS DATA Record your data in Excel at the computer located at the front podium Your Instructor will make the complete data set available for you to use while completing the homework assignment

24 HOMEWORK Complete and turn in the questions on pages 6-19 to 6-22 Dont forget to print the entire spirogram (landscape format) you recorded to include in your lab report. Use vertical brackets ( [ ] ) to identify and label the tidal, inspiratory reserve, expiratory reserve and residual volumes; and total lung, vital, expiratory and inspiratory capacities on your spirogram. Lab 6-21, Question 4. Use a scatterplot, not a line graph! Remember to completely label your graphs! Complete Assignment 6 on MasteringAandP.
