What equipment is used for airway suctioning in a critical care setup?

• A. Suction canister and suction gauges
• B. Oxygen cylinder only
• C. Defibrillator pads
• D. Blood pressure cuff

Answer: (C)

Airway suctioning relies on a device that creates controlled negative pressure and a collection system to remove secretions from the airway. The essential setup includes a suction source, a collection canister, tubing, and a suction catheter or tip, with a regulator and gauges to monitor the negative pressure. In the list presented, the suction canister and suction gauges are the components that directly support suctioning by collecting material and allowing the clinician to monitor and control suction strength. The other items don’t perform suction: defibrillator pads are for shock therapy, an oxygen cylinder supports oxygenation but does not suction, and a blood pressure cuff is used to measure pressure.
