Document Summary
Respiratory distress syndrome due to lack of surfactant causing collapse of alveoli. Emphysema, the elastic tissue has been damaged including alveoli making it difficult to exhale air. Charles law the given quantity of a gas is directly proportional to its absolute temperature. Surface tension of the alveoli and distal bronchioles. Alveolar ventilation = (minute volume respiratory rate) x tidal volume. Only air that enters the alveoli is available for gas exchange. Not all air reaches the alveoli, this air remaining in the conducting passages is called anatomical dead space. Sum of the anatomic dead space and any pathological alveolar dead space is physiologic dead space. Specifically measures the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled. Tidal volume: volume of air inhaled and exhaled in one cycle during quiet breathing. Inspiratory reserve volume: air in excess of tidal volume that can be inhaled with max.
