Respiratory System Flashcards
Vital Capacity =
ERV + TV + IRV = VC
Expiratory Reserve Volume + Tidal Volume + Inspiratory Reserve Volume = Vital Capacity
Hering-Breuer Reflexes: involved in?
Involved in Forced Breathing
>Inflation: prevents over expansion
>Deflation: inhibits Expiratory centers,
stimulates Inspiratory centers
Total Lung Capacity (TLC) =
VC + RV = TLC
Vital Capacity + Residual Volume = TLC
Expiratory Reserve Volume (ERV): definition
> the Additional amount of air capable of being Exhaled
Residual Volume (RV): definition
> amount of air in Lungs After max Exhalation
>approximately 1.2 Liters
Minute Volume (MV) =
RR x TV = MV
Respiration Rate x Tidal Volume = Minute Volume
Minute Volume (MV): definition
> amount of air Exchanged btw the Lungs and the Environment per Minute
Tidal Volume (TV or Vt): definition
> amount or volume of air moved In or Out of the Lungs per Breath
Inspiratory Reserve Volume (IRV): definition
> Additional amount of air that Can be Inhaled
HyperCarpnia: cause and effect
> caused by Hypoventilation (low respiration rate)
>effect is Increased CO2 levels
HypoCarpnia: cause & effect
> caused by Hyperventilation (Excess Ventilation)
>effect is: Low CO2 levels
