IPPV Designed to deliver fresh gas to the patient Versatile Reliable Monitoring of volume & pressure Compatible with vapors Suitable for requirements & environment No single classification

Elements of classification Control - how the ventilator delivers gas Volume Pressure Cycling - how the ventilator switches I:E Time Pressure / Flow Triggering - how inspiration is initiated

Volume Control

Pressure Control

Volume Control & Pressure Limit

Comparison Volume Controlled Pressure Controlled Constant tidal volume Precise control of PaCO2 Potential for high airway pressure Problems with leaks Pressure Controlled Reduced peak pressure Improved gas exchange Compensates for leaks Changes in compliance and resistance alter volume

Triggering CMV (S)IMV Pressure Support ventilation (PS) Controlled mandatory ventilation Pressure Control (PC) (S)IMV (Synchronized) intermittent mandatory ventilation Pressure / Volume Pressure Support ventilation (PS) PEEP / CPAP / BIPAP

PEEP / CPAP Aims to increase FRC Recruit alveoli Optimise V/Q Reduces CO Reduces abdo blood flow Alveoli over-distension / rupture

BIPAP & CPAP

Types of Ventilators Variations depending on requirements Theatres - Versatile, simple & works with vapors ITU - Versatile with extensive control Transfer - Compact, robust, powered by gas Manual - Compact, robust, self inflating
