Respiratory Review

QuestionAnswer
TV [ Tidal Volume ] air exhaled = 500mL
ERV [ Expiratory reserve Volume ] Largest additional volume of air that one can forcibly exhale after expiring tidal air = 1L -> 1.2L
IRV [ Inspiratory Reserve Volume ] amount of air that can be forcibly inspired over and above typical inspiration = 3.3L
RV [ Residual Volume ] amount of air you cannot forcibly expire = 1.2L
MV [ Minimal Volume ] remains in lung tissue = 40% of RV
VC [ Vital Capacity ] IRV + TV + ERV = VC
IC [ Inspiratory Capacity ] IC = TV + IRV maximum amount of air a person can inspire after typical a typical expiration
FRC [ Functional Residual Capacity ] FRC= ERV + RV amount of air left in the lungs at the end of a typical expiration without contracting expiratory muscles = 2.2L -> 2.4L
TLC [ Total Lung Capacity ] total air a lung can hold = sum of all 4 lung volumes
AVV [ Alveolar Ventilation Volume ] volume of inspired air that actually reaches the alveoli AVV = TV - Dead Space Volume
TMV [ Total Minute Volume ] volume moved per minute = 500mL / cycle x 12 Breathes = 6L
FEV Test [ Forced Expiratory Volume Test] determine the presence of obstruction by measuring the volume of air expired per second during forced expiration.
Boyles Law The volume of a gas varies inversely with its pressure at a constant temperature [ P1V1 = P2V2] / PV = k
Dalton's Law - Partial Pressures the partial pressure of a gas in a mixture of gases is directly related to the concentration of that gas in the mixture and to the total pressure of the mixture
Bohr Effect Increase in Carbon Dioxide levels in blood will decrease blood Ph ( more acidic) = decreases the affinity of hemoglobin for oxygen
Haldane Effect Deoxygenation of the blood ( makes it more basic ) increased its ability to carry carbon dioxide
Spirometer Tool used to measure volume of air exchanged in breathing.
Spirogram Graphic recording of change in pulmonary volumes observed during breathing
