2 Lab 6 Activities Identify parts of the respiratory system Respiratory tree, thoracic organs, and larynx modelsFresh lung (if available)Examine histology of the:TracheaLungExamine the operation of the lung modelBiopac L012-Pulmonary Function IMeasure lung volumes and capacities
3 Respiratory System Structure Conduction zone: pathway for pulmonary ventilationRespiratory zone: membrane for gas exchange external respirationClinically, two parts:Upper respiratory tractLower respiratory tract
4 Respiratory System Structure Histology reflects the different functions of the different parts of the systemPosition in respiratory pathway determines cell typenon-keratinized stratified squamouspseudostratified ciliated columnarcuboidal ciliatedsimple squamous / Type I Alveolar cells
15 Spirometry: Calibration InletInletInsert the calibration syringe/filter assembly into the side of the airflow transducer labeled "Inlet." Follow pop up window instructionsWait for 8 seconds of no air flow,Then do your 5 syringe cycles.
16 Experimental Treatments- Different from Biopac Experimental Treatments- Different from Biopac!!!! and don’t forget the nose clip!!!4 normal breaths (4 inhales/4 exhales)Inhale as deeply as possibleExhale to normal depth3 normal breathsExhale as much as possible at end of3rd exhalationInhale as much as possible, then exhale as fast and completely as possible (you will use this data segment in activity 3)Click Stop- look at your recording and redo if necessaryIf it’s good, select done and analyze your data.
17 BioPac Spirogram Example Data If you get a negative value, just put the absolute value.This part is in addition to what Biopac Lesson 12-Lung 1 prompts you to do!1 regular exhale1 strongestinhale3 regularbreaths1 strongestinhale1 strongest exhale3 regularbreaths3 regularbreaths1 strongest exhale
18 Biopac: Data Analysis Ch 2 P-P Measures Tidal Volume Record in Table 1 on page Lab 6-17
19 Biopac: Data Analysis P-P Measures Inspiratory Capacity Record in Table 1 on page Lab 6-17
20 Biopac: Data Analysis Delta Measures Inspiratory Reserve Volume Record in Table 1 on page Lab 6-17Use similar methods to determine:Expiratory Reserve VolumeVital Capacity
21 Biopac: Data Analysis (Activity 5) Forced Expiratory Volume is the % of your forced vital capacity you can expel in1,2, or 3 seconds.RESET MEASUREMENT BOXES!!!!!BOX 1- DELTA T BOX 2 P-P, ALL OTHER BOXES- NONEUSE I-beam to bracket one second of data starting at peak of last maximalinhalation. P-P will give you FEV1 then highlight the 1st 2 seconds of data startingat peak for FEV2 and then the 1st 3 seconds for FEV3Record in Table 1 on page Lab 6-17
22 Biopac: Data AnalysisTo measure FVC highlight the recording from just before last maximal inhalation tojust after peak of the last maximal exhalation- use P-P value.Record in Table 1 on page Lab 6-19
23 Record your data in Excel at the computer located at the front podium Summary of Class DataRecord your data in Excel at the computer located at the front podiumYour 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 6-17 to 6-20 Don’t 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 6-19, Question 4. Remember to completely label your graphs!Complete Assignment 6 on MasteringAandP.
