Some Important Numbers MINUTE VENTILATION = TIDAL VOLUME x BREATHS/MIN. ~80 mls/ kg/ min ALVEOLAR VENTILATION=(TIDAL VOLUME - DEAD SPACE) X BREATHS/MIN ~70 mls/ kg/ min Fresh Gas Flow rates often set in relation to these numbers to prevent rebreathing.
Classifications § Numerous classifications since anaesthesia began !!! 1. Open, semi-open, semi-closed and closed 2. Rebreathing and Non-rebreathing systems 3. Breathing systems with CO2 absorption/ without CO2 absorption 4. Unidirectional flow/ bidirectional flow systems 5. The Mapleson Classification
