1.
Anstomic dead space volume (VD): * The volume of air that occupies the non-respiratory conducting airways
2.
Expiratory reserve volume: * Increased volume of the expired air
* 1,400mL
3.
Forced Expiration: * During heavy exercise, singing, etc.
* Involves contraction of abdominal wall muscles
4.
Forced Expiratory Volume (FEV): * The amount of air exhaled in the 1st, 2nd & 3rd second of a forced vital capacity test.
5.
Forced Vital Capacity (FVC): * The amount of air forcefully expired after a maximal inspiration.
6.
Functionsl Residual Capacity (FRC): * Volume in the lungs after normal exhalation
7.
Hypercapnia: * An increased amount of CO2 in the blood
8.
Hyperkalemia: * An increased amount of potassium in the blood
9.
Hypocapnia: * A decreased amount of CO2 in the blood
10.
Hypoxemia: * When the PaO2 is less than 80 mm Hg
11.
Inspiratory Capacity (IC): * The amount of air that can be inspired after a normal
12.
Inspiratory reserve volume: * Forced inspiration
* Increases the volume of air beyond the tidal volume by 2,900mL
13.
Maximum Inspiratory Effort: * Involves the accessory muscle of respiration:
1. Erector spinae
2. Pectorals minor
3. Scalene and sternocleidomastoid muscles
* Heavy breathing after you exercise
* Help increase the size of the thoracic caipvity larger than normal
14.
Minute Volume Ventilation (VE): * The amount of air expired in one minute.
* This is equal to the product of the tidal volume & the respiratory rate
15.
Peak Expiratory Flow (PEF): * The maximum flow of air during the begining of a force expiratory breath
16.
Residual Volume: * The amount of air remaining in the lungs after a forced expiration
* 1,000mL
17.
Tidal Volume: * Normal, relaxed breathing
* About 500mL
18.
Total Lung Capacity (TLC): * Lung volume measured at the end of a maximal inspiration.
19.
Vital Capacity: * Maximum volume of air that can be inhaled plus the maximum volume of air that can be exhaled.
* Depends on:
Inspiratory reserve volume
&&
Expiratory reserve volume
