| Question | Answer |
| In Respiratory care, Therapeutics deal with 4 area . What are they? | 1. Ventilation 2. Oxygenation 3. Perfusion 4. Underlying Disease / Problem |
| What is Ventilation? | Ventilation must occur. Ventilation is nothing more than moving Air into the Alveoli Space & CO2 out of those same spaces(Lungs). |
| What is Oxygenation? | Oxygenation occurs when O2 passes through the alveolar capillary membrane into the blood stream. |
| What is Circulation? | Circulation occurs to deliver O2 to the tissues. This is done through contraction of the heart & descending pressure gradient that exists in the vascular system. |
| What is Perfusion? | After Circulation Perfusion occurs, O2 crosses from the blood into the tissues through pressure gradient. This occurs because of the difference of the partial pressure of O2 between blood stream & tissue. |
