Definition
Energy expended by patient and/or ventilator to move gas in and out of the lungs.
Includes work needed to overcome elastic and flow-resistive forces of respiratory system and breathing system |

Definition
deliberate increase in tidal volume for one or more breathes
Normally 9-10 per hour
Maintains pulmonary compliance
Releases and evenly distributes surfactant |

|
Term
|
Definition
| Fresh gas flow is prevented from effecting tidal volume by adjusting the volume delivered by ventilator |
|
|
Term
|
Definition
| Fresh gas prevented from entering the breathing system during INSPIRATION to prevent FGF effecting volume delivered to patient |

Reflects eleastic properties of the lungs, thorax, abdomen, and breathing system
35-100 mL/cm H20
Paralytics will increase CHEST WALL compliance but not LUNG compliance |
