WebDec 8, 2024 · Increased alveolar dead space will increase the tidal volume requirements in proportion to the change in the ratio between dead space and alveolar ventilation The section from the 8th edition of Nunn's (p.123) which deals with this topic is relatively short, but that appears to be all that is required to answer CICM primary exam questions. WebPressure Gradients-occur when the force per unit area is greater in one area than in another. Air moves from the region of higher pressure to the region of lower pressure until the pressure in the two regions becomes equal An increase in volume of the thoracic cavity, with an accompanying decrease in pressure, results in air moving into the lungs during …

Physiological consequences of increased dead space

WebAn increase in the respiratory rate and a decrease in tidal volume indicate a pattern of rapid shallow breathing. If the total ventilation does not change, alveolar ventilation will decrease because of the fact that the first 150 ml of each inspiration is dead-space breathing. An increase in the rate means an increase in dead-space breathing.
