Document Summary
True or false: anaesthesia impairs central respiratory regulation and tone of respiratory muscles. True: at high doses, some anaesthetics globally depress muscular activity and the respiratory effort. True: release of inflammatory mediators by some anaesthetic agents produces bronchospasm, resulting in hypoxia, hyperinflation and air trapping. True: dry anaesthetic gases and prolonged mechanical ventilation may. Impair normal mucociliary mechanism and lead to atelectasis from mucus-plugs. True: there is a risk of aspiration pneumonitis with general anaesthesia when airway reflexes are. Adverse effects of: pneumonia, respiratory failure (usually defined as the need for mechanical. Anaesthesia include: ventilatory support: bronchospasm, atelectasis (shrinks air spaces, hypoxaemia, exacerbation of underlying chronic lung disease. Top l = normal: 1 impaired ventilation (bronchospasm not let enough air get out of the air space) hypoxemia. Bronchospasm restricts ventilation: 2 blocked ventilation (mucous plug, alveolus collapses) hypoxemia (low o2) In chronic bronchitis mucous plug could block ventilation: 3 alveolar dead space (blocked perfusion) hypoxemia.
