Damping describes the resistance of a system to oscillation resulting from a change in the input. Damping is the result of frictional forces working in that system.… Read more “Damping”
Drowning is death while submerged in water, and near-drowning is suffocation while submerged with survival (at least temporary). If water does not enter the airway, asphyxia is… Read more “Drowning: Specific points”

The functional residual capacity of the infant’s lungs is only one half that of an adult in relation to body weight. This difference causes excessive cyclical increases and decreases in the newborn baby’s blood gas concentrations if the respiratory rate becomes slowed because it is the residual air in the lungs that smooths out the blood gas variations.
The functional residual capacity equals the expiratory reserve volume plus the residual volume. This is the amount of air that remains in the lungs at the end of normal expiration (about 2300 milliliters).
The resting position of the lungs and chest wall occurs at FRC. If isolated, the lungs, being elastic, would collapse to a volume <FRC. The isolated thoracic… Read more “INTRA-PLEURAL PRESSURE”
