Inhalational anesthetic agents effect on respiratory tract all true except-
Potent inhalational agents and N2O reduce ciliary movement and clearance of mucus. The inadequate clearing of mucus may result in plugging, atelectasis and hypoxia. other effects on respiratory system 1. depress respiratory centre 2. blunt hypoxic and hypercapnic drive 3. bronchodilatation 4. inhibits hypoxic pulmonary vasoconstriction
The volatile anaesthetic agents relax airway smooth muscle
They blunt respiratory drive
Supress respiratory centre
They increases ciliary movement
