| Ohm's Law |
The current flowing through
a circuit is directly proportional to the electromotive
force (emf) across the circuit. Expressed as: E=IR in
which E is the emf (voltage), I is the current (amperes),
and R is the electrical resistance (ohms). This is an
analog of the relation defining airway resistance, Raw:
(pressure difference along the airways) = (flow through
the airways) x Raw. |

| Oxygen |
O2 - The gas required by
the body for metabolism; it enters the body and is transferred
to the blood by the lungs. |
| Oxygen
Saturation |
The ratio of the amount
of oxygen carried by blood to the maximum amount that
it could carry, expressed as a percent. |
| Oxygen Saturation Curve |
The relation between the
amount of oxygen carried by the blood and the partial
pressure of oxygen in the blood. It is affected by the
partial pressure of carbon dioxide, hematocrit, condition
of the red blood cells, and temperature of the blood. |
