5 Written Questions

1. -Maximum volume of air that the lungs can hold
   *VC+ RV
2. -volume of air exchange btwn atmosphere (gases) & alveoli (the blood) each minute. (usable air)
   RR= At rest 4.2L/m
   -It is more efficient to increase TV than to increase RR
   *RR x (TV - dead air space)
3. -volume of air moving in and out of the lungs each minute. (unusable)
   RR= At rest: 6L/m Maximal: 150L
   *TV x RR= PV
4. -the extra volume of air that can be actively EXPIRED by the contraction of expiratory muscles beyond that normally expired
5. -the minimum volume of air remaining in the lungs after maximal expiration

5 Multiple Choice Questions

2. -Cant breath out!
   -Below 80%
   -FEV1/FVC X 100
   examples: Asthma & Emphysema
   1. Obstructive lung disease
   2. Total lung capacity
   3. Residual volume
   4. Restrictive lung disease
3. -volume of air that can be expired during the 1st second of expiration in a vital-capacity determination.
   *FEV1/FVC X 100
   1. FEV1
   2. Tidal volume
   3. vital capacity
   4. Residual volume
4. -the volume of air entering or leaving the lungs in a single breath during quiet breathing
   1. Tidal volume
   2. Residual volume
   3. FEV1
   4. vital capacity
5. -Cant breath in!
   -Above 80%
   -FEV1/FVC X 100
   examples: Fibrosis, pneumonia
   1. Total lung capacity
   2. respiratory rate
   3. Obstructive lung disease
   4. Restrictive lung disease

5 True/False Questions

1. Inspiratory reserve volume → the extra volume of air that can be maximally inspired over & above the tidal volume

   True        False

2. Functional residual capacity → -volume of air in the lungs at the end of a normal passive expiration

   True        False

3. respiratory rate → breaths/minute

   True        False

4. vital capacity → -Maximum volume of air that can be moved in & out during a single breath
   *IRV+ TV+ ERV

   True        False

5. Inspiratory capacity → breaths/minute

   True        False
