Study Notes
Normal Ventilation
- The body's system responds to changes in need, like during exercise, where a tenfold increase in oxygen requirement can occur.
- Arterial carbon dioxide (PCO2) is tightly controlled between 5.1 - 5.5 kPa, a main controller of respiration.
- As arterial PCO2 rises, the tidal volume increases, bringing it back to the normal range.
- This process links to blood gas analysis and respiratory compensation for reducing metabolic acidosis.
- Inspiratory pressure carries oxygen to the upper aspects of the lungs.
- Oxygen travels to the lower airways and alveoli through a diffusion and concentration gradient, primarily assisted by gravity, especially when standing.
