Which airway management device provides the best protection against pulmonary aspiration of gastric contents?
Answer: Cuffed endotracheal tube (ETT)
A cuffed ETT physically isolates the trachea from the esophagus with an inflated low-pressure high-volume cuff, providing superior aspiration protection.
What is the primary advantage of a video laryngoscope over a conventional direct laryngoscope for difficult airway management?
Answer: Provides improved glottic visualization without requiring direct line of sight
Video laryngoscopes use a distal camera to transmit the glottic view to an external screen, improving visualization in difficult airway scenarios without needing a direct line of sight.
To prevent tracheal mucosal ischemia, at what pressure range should an endotracheal tube cuff be maintained?
Answer: 20-30 cmH2O
ETT cuff pressure should be maintained at 20-30 cmH2O to provide an adequate airway seal while avoiding mucosal ischemic injury.
Which ventilator mode delivers a preset tidal volume with each breath regardless of changes in airway compliance or resistance?
Answer: Volume control ventilation (VCV)
Volume control ventilation delivers a set tidal volume per breath regardless of changes in airway resistance or lung compliance, though peak pressures may vary.
What is the primary physiologic purpose of applying PEEP (positive end-expiratory pressure) during mechanical ventilation under anesthesia?
Answer: To prevent alveolar collapse at end-expiration and maintain FRC
PEEP maintains alveoli open at end-expiration, preventing atelectasis and maintaining functional residual capacity above closing capacity.
What does the pre-use anesthesia machine checkout procedure recommended by the FDA primarily ensure?
Answer: Identification of equipment faults before patient care begins
The FDA-recommended anesthesia machine checkout is a standardized pre-use safety inspection to identify equipment faults or gas supply problems before anesthetic delivery.
