Anesthetic Equipment and Monitoring — Flashcards

Flashcard 81: Venturi mask provides the highest oxygen concentration (FiO2) of _____% at a flow rate of 15 L/min

Answer: 60

Flashcard 82: Which catheter is used to measure pulmonary capillary wedge pressure (PCWP) and cardiac output via thermodilution?

Answer: Swan-Ganz catheter (Pulmonary artery catheter)

Extra: The Swan-Ganz catheter is a multi-lumen flow-directed catheter with a balloon at the tip. It is used to measure: 1. Right atrial pressure (CVP) 2. Right ventricular pressure 3. Pulmonary artery pressure 4. Pulmonary capillary wedge pressure (PCWP) 5. Cardiac output (via thermodilution)

Flashcard 83: The **hanger yoke** check valve is a part of the _____ pressure system of the anesthesia machine.

Answer: High

Flashcard 84: _____ is the most commonly used indicator dye in soda lime.

Answer: Ethyl violet

Flashcard 85: Pipeline pressure gauge is a part of the _____ pressure system of the anesthesia machine

Answer: intermediate

Flashcard 86: Cylinder pressure gauge is a part of the _____ pressure system of the anesthesia machine

Answer: high

Flashcard 87: The black pipeline in operation theatre is for _____.

Answer: N2

Flashcard 88: _____ is the most sensitive depth of anesthesia monitor.

Answer: Middle latency auditory evoked potential

Flashcard 89: Opening which valve on the anaesthesia machine bypasses the vapourisers, and so is devoid of anaesthetic agents?_____

Answer: Oxygen flush valve

Flashcard 90: What are the contents of the **Yellow kit** (Plan B) in a standardized **Difficult Airway Trolley**?

Answer: **Supraglottic Airway Devices (SADs)** (e.g., Laryngeal Mask Airway (LMA), i-gel, ProSeal LMA)

Extra: According to the **Difficult Airway Society (DAS) 2015 guidelines**, a standardized difficult airway trolley is color-coded to match the management plans: - **Green (Plan A):** Initial tracheal intubation (laryngoscopes, endotracheal tubes, stylets, bougies). - **Yellow (Plan B):** Secondary intubation / Supraglottic Airway Devices (SADs). - **Red (Plan D):** Emergency front of neck access (CICO - Can't Intubate, Can't Oxygenate; e.g., scalpel, bougie, cricothyroidotomy kit). *Note: Plan C (maintenance of oxygenation via face mask ventilation) is sometimes assigned a blue color in regional trolley setups.*
