Rabbits are small mammals found naturally in Europe, South Africa, Sumatra and Japan. Rabbits are also often found in the desert regions of the Middle East where the rabbits inhabit the greener parts of the deserts where there is enough food and water for the rabbits to survive. Rabbits are herbivores that feed on mainly on grass, but rabbits also eat nuts and berries and often fruit and vegetables.
Mean airway pressure typically refers to the mean pressure applied during positive-pressure mechanical ventilation. Mean airway pressure correlates with alveolar ventilation, arterial oxygenation, hemodynamic performance, and barotrauma.
Airway pressure release ventilation was described initially by Stock and Downs in 1987 as a continuous positive airway pressure (CPAP) with an intermittent release phase.APRV begins at a pressure higher than the baseline pressure and follows with a deflation to accomplish tidal ventilation.his is a type of inverse ratio ventilation. The exhalation time (T low) is shortened to usually less than one second to maintain alveoli inflation. Fundamentally this is a continuous pressure with a brief release.
