Why would an elderly or ill patient with a low Tidal Volume exhibit an increase in respiratory rate? a. To maintain Vital Capacity b. To maintain FEV c. To maintain minute ventilatiorn 4 What is the significance of the equation FEV/FVC x 1007 t "s the volume of expiratory b. It is the volume of IRV and ERV forcefully expired in 1 second c. It is the 96 vital capacty forcefully expired in 1 second: reserve volume forcefully expired in 1 second 5. Why does someone with bronchoconstriction have a reduced FEV1? a. Because b. Because it takes these patients longer to expire air c. Because these patients have no surfactant and the lungs collapse reduces IRV 6. A collapsed lung would cause Tidal Volume to a. Increase 7. The following pulmonary function tests are collected: VC 4000 ml IRV 2000 ml TV 500 m Solve for ERV

Explanation / Answer

1)Respiratory rate:It is rate at which breathing occurs, this is usually measured in breaths per minute and is controlled by repiratory centre. 2)Minute ventilation or respiratory minute volume : it is the volume of gas inhaled or exhaled from the persons lungs per minute.the equation is minute ventilation=tidal volume(ml) x breathing rate(bpm). 4)option b 5)option b. 6)option b. 7)ERV=IRV+TV-VC, 2000+4000-500=5500ML
