Term
What is tidal volume (VT)?
Definition
Volume of normal breathing?
Term
What is inspiratory reserve volume (IRV)?
Definition
Volume of inspired air above tidal volume
Term
What is the expiratory reserve volume (ERV)?
Definition
Volume expired below tidal volume
Term
What is Residual volume (RV)?
Definition
Trapped gas within the lung
Term
What is inspiratory capacity (IC)?
Definition
IC= VT+IRV
Term
What is functional residual capacity (FRC)?
Definition
FRC=ERC+RV
Term
What is vital capacity (VC)?
Definition
IRC+VT+ERV
Term
What is total lung capacity (TLC)?
Definition
VC+RV
Term
What is normal tidal volume?
Definition
500 mL
Term
What is the Effective Alveolar Ventilation (VA)?
Definition
VA=frequency(VT-VD)
Term
What is Minute Ventilation/Total Ventilation?
Definition

Total volume of air entering or leaving the lung each minute.

Minute Ventilation = VT x RR

Term
How does Pressure relate to Temperature and Volume?
Definition

P is proportional to T

P is inversely proportional to V

Term
What is the Barometric Pressure (PB) at sea level?
Definition
760 mmHg
Term
What is the Partial Pressure of O2 at sea level?
Definition
PO= .21(760) = 160mmHg
Term
How does increasing Temp affect PH2O?
Definition
It increases the capacity of water.
Term
What is the PH2O in the body?
Definition
47 torr
