| Question | Answer |
|---|---|
| inspiratory reserve volume | maximal amount of air that can be taken into the lungs at the end of normal inhalation |
| expiratory reserve volume | maximal amount of air that can be pushed out of the lungs at the end of normal exhalation |
| residual volume | volume of air left in the lungs after maximal exhalation |
| inspiratory capacity | maximal volume of air that can be inhaled |
| functional residual capacity | volume of air left in the lungs at the end of normal exhalation |
| Vital capacity | volume of air that can be forced out the of the lungs following a maximal inhalation |
| total lung capacity | total volume of air that can be contained in the lungs |
| Dead space | conducting airways (no respiration) Does not take part in gas exchange Body weight in pounds -> mL of dead space |
| Alveolar ventilation | volume of air per minute that reaches the alveoli and respiratory areas Takes part in gas exchange 4.2 L/min for 150 lb. person 500 mL-150 mL = 350 mL 350 mL*12 breaths/min = 4200 mL/min = 4.2 L/min |
| eupnea | normal breathing rate and depth |
| apnea | breath holding |
| dyspnea | painful or difficult breathing |
| tachypnea | rapid breathing rate |
| minute ventilation | VE = VT * fb |
