It also optimises patient's ventilatory condition and airway patency. Such knowledge has influence on airway management, lung isolation during anaesthesia, management of cases with respiratory disorders, respiratory endoluminal procedures and optimising ventilator strategies in the perioperative period. Understanding of ventilation, perfusion and their relation with each other is important for understanding respiratory physiology. Ventilation to perfusion ratio alters with anaesthesia, body position and with one-lung anaesthesia. Hypoxic pulmonary vasoconstriction, an important safety mechanism, is inhibited by majority of the anaesthetic drugs. Ventilation perfusion mismatch leads to reduced arterial oxygen concentration mainly because of early closure of airway, thus leading to decreased ventilation and atelectasis during anaesthesia.

The pulmonary capillaries occupy a huge area of the alveolar wall, and a red cell spends about 0. Concerning the blood-gas barrier of the human lung, The thinnest part of the blood-gas barrier has a thickness of about 3 mm. The total area of the blood-gas barrier is about 1 square meter.

If the pressure in the capillaries rises to unphysiologically high levels, the blood-gas barrier can be damaged. Oxygen crosses the blood-gas barrier by active transport. When oxygen moves through the thin side of the blood-gas barrier from the alveolar gas to the hemoglobin of the red blood cell, it traverses the following layers in order: A.

Epithelial cell, surfactant, interstitium, endothelial cell, plasma, red cell membrane. Surfactant, epithelial cell, interstitium, endothelial cell, plasma, red cell membrane. Surfactant, endothelial cell, interstitium, epithelial cell, plasma, red cell membrane.

Concerning the airways of the human lung, A. The volume of the conducting zone is about 50 ml.

The volume of the rest of the lung during resting conditions is about 5 liters. A respiratory bronchiole can be distinguished from a terminal bronchiole because the latter has alveoli in its walls. Concerning the blood vessels of the human lung, A. The pulmonary veins form a branching pattern that matches that of the airways.

The average diameter of the capillaries is about 50 mm.

On the average, blood spends about 0. The mean pressure in the pulmonary artery is about mm Hg. Then total ventilation and alveolar ventilation, which is the amount of fresh gas getting to the alveoli, are discussed. The lung that does not participate in gas exchange is dealt with under the headings of anatomic and physiologic dead space. Finally, the uneven distribution of ventilation caused by gravity is introduced.

With each inspiration, about ml of air enters the lung tidal volume. Note how small a proportion of the total lung volume is represented by the anatomic dead space. Also note the very small volume of capillary blood compared with that of alveolar gas compare Figure Some of these can be measured with a spirometer Figure During exhalation, the bell goes up and the pen down, marking a moving chart. First, normal breathing can be seen tidal volume.

Next, the subject took a maximal inspiration and followed this by a maximal expiration. The exhaled volume is called the vital capacity.
