Bio 365s Respiratory Intro—Anatomy, Gas laws, SpirometryTA note: Refer to pages 578-9 in the text (pp.567-8 in 4e); use powerpoint slidesa. briefly explain volume displacement spirometry (can use on-line resources for further info)b. talk through the process of recording a spirogram –use the text under “Lung Volumes” for your guidec. instruct students to fill out # 1 on worksheet as you go along.d. explain that lung capacities add 2 or more volumes; talk through the 4 lung capacitiese. This will be the only lecture on spirometry! Please be thorough.SpirometryUsing the spirogram above and Figure 17.7 (17-8), fill in the chart regarding standard lung volumes and capacities.Lung volume or capacityValue (mL)Description1Tidal volume500 mLVolume of air that moves in a single inspiration or expiration2Inspiratory Reserve volume3000Additional volume that can be inspired above tidal volume3Expiratory Reserve volume1100Maximum volume of air that can be exhaled at end of normal expiration4Residual volume1200Volume of air left in respiratory system after max expiration1 + 2 Inspiratory capacity3500Tidal volume + inspiratory reserve3+ 4Functional residual capacity2300ERV + RV—amount left in lungs after normal expiration1 + 2 + 3Vital capacity4600TV + IRV + ERV = max air that can be voluntarily moved into or out of the resp system with one breathAll Total Lung Capacity5800Vital capacity + residual volumeTA note:
