    What are some reasons why airway management is important?

    <p>Airway management is important because it allows the delivery of oxygen and volatile anaesthetic agents to the patient, removes carbon dioxide, protects the airway from obstruction, and enables positive pressure ventilation if required.</p> Signup and view all the answers

    What are some considerations when using endotracheal tubes?

    <p>When using endotracheal tubes, it is important to check them before use, inflate the cuff to 25mmHg using a manometer if possible, and consider using cuffed tubes to prevent secretions from coming up and going down the trachea.</p> Signup and view all the answers

    What are some advantages of using PVC and silicone tubes for endotracheal intubation?

    <p>PVC and silicone tubes are less prone to cracking and kinking, non-irritant, allow visualization of blockages, and usually have a high volume low pressure cuff.</p> Signup and view all the answers

    What are some advantages of using laryngeal mask airway (LMA) for airway protection during short procedures?

    <p>LMA is achieving popularity due to its effectiveness and patient comfort. It can be used to protect the airway similar to an endotracheal tube, allows for ventilation, and can be used for bronchoscopy.</p> Signup and view all the answers

    What are some complications that can occur during airway management?
