Kin 470 lab 5 notes- Pulmonary volumes and capacitieso 4 volumes and 4 capacitieso see pages 206-208o lung volume (mL) tall men have larger values size depends on size of thoracic cavityo residual volume – remaining air in lungs despite trying to exhale all of them- volumeso tidal volume (TV) volume of one breath during quiet breathingo inspiratory reserve volume (IRV) volume you can inhale with maximal efforto expiratory reserve volume (ERV) volume you can exhale with maximal efforto residual volume (RV) volume remaining in lungs after maximal exhale- total lung capcity – everything you have in lungso varies person to person- FEV1o Forced expiratory volume (in 1 second)o Graph Blow out all air in lungs as quickly as you can This is what we will determine in lab Large percentage of total lung volume Typical – this is about 80% of vital capacity (VC) COPD FEV1 = 33% of VC- Typical pulmonary function testo Have someone breathing into transducero Measures air flowo Something you do in lab or as a clinician – diagnose people with conidtion Asthsma COPD Restrictice lung disease Chronic dyspnea Duchenne muscular dystrophyo Useful test for pulmonary disorders- Methodso Laid out well in lab handouto Things in all caps/bold that are really importanto Perform 1 resting measurement and 3 exercise measurements of lung volumes and capacitieso During the resting measurement you will calculate FEV1o Once a recording is done, analyze the data, and collect the 4 volumes, hit redo to redo
