: Provides a high-flow (35–75 L/min) burst of pure oxygen directly to the common gas outlet in emergencies.
: Must always be checked and ready to clear the airway of secretions or fluids.
: Continuous measurement of blood oxygen saturation ( SpO2cap S p cap O sub 2 Capnography : Monitors exhaled CO2cap C cap O sub 2 to confirm proper airway placement and ventilation status. Essentials of anaesthetic equipment
: Intermittent monitoring of arterial pressure.
: Individually calibrated glass tubes that measure and indicate the specific flow rate of each gas in litres per minute. : Provides a high-flow (35–75 L/min) burst of
: A mechanical or electronic link that prevents delivering a gas mixture with less than 25% oxygen.
: Specific conduits placed in or above the trachea to deliver gases directly. : Intermittent monitoring of arterial pressure
Safety is the primary driver of modern anaesthetic design, featuring multiple layers of redundancy to prevent human or mechanical error. Essential Safety Mechanisms
