Monitoring of different Respiratory parameters during Anesthesia Ventilation

Abstract

good understanding of respiratory physiology is essential to ensure patient safety during anesthesia. Also an understanding of the disease processes that can affect the lungs and pleura allows the anaesthetist to account for the potential complications of these conditions and manage the anaesthetic accordingly.

Restrictive lung condition These are conditions where lung expansion is restricted. This can be due to lung parenchymal abnormalities, diseases of the chestwall and pleura, or neuromuscular conditions.

Obstructive conditions Resistance to air flow can be caused by three main mechanisms: • Occlusion of the airway lumen (e.g. secretions) • Pathology within the airway wall (e.g. smooth muscle contraction) • Pathology outside the airway (e.g. neoplasm) General anaesthesia causes respiratory impairment
