Terms | Definitions |
|---|---|
 the movement of air into and out of the lungs | ventilation |
| exchange of gas between blood and air | respiration |
| measurement between parietal and visceral pleurae | intrapleural pressure (Ppl) |
| intrapleural pressure (Ppl) is normally ____ cmH2O at the end of exhalation during spontaneous breathing | -5 |
| intrapleural pressure (Ppl) is about ____ cmH2O at the end of inspiration | -10 |
| transairway pressure (Pta) | Pm - Palv (difference between mouth and alveoli) |
| Pm (mouth pressure) is also called | airway pressure (Paw) |
| transthoracic pressure (Pw) | Palv - Pbs (difference between alveoli and body surface pressure) |
| transpulmonary pressure (Pl) | Palv - Ppl (difference between alveoli and intrapleurae) |
| transrespiratory pressure (Ptr) | Pm - Pbs (difference between mouth and body surface pressure) |
| normal baseline pressure is 0 on monometer and indicated | during expiration and before inspiration |
| volume left in the lungs after exhalation | PEEP |
| extrinsic PEEP | set by operator |
| intrinsic PEEP | volume left in lungs accidentally, usually when the patient does not have enough time to exhale before the next breath |
| the highest pressure recorded at the end of inspiration | peak pressure |
| peak pressure is also called | PIP or PAP |
| measurement taken after a breath has been delivered and before exhalation has begun | plateau pressure |
| plateau pressure is like holding your breath at the end of ________ | inspiration |
| tendency of a structure to return to its original form after being stretched by an outside force | elastance |
| compliance is defined as | change in volume/change in pressure |
| compliance is measured in | L/cmH2O |
| in spontaneous breathing individuals, the total compliance is about _____ L/cmH2O (or 100 ml/cmH2O) | 0.1 |
| compliance can range from ____-____ L/cmH2O | 0.05-0.17 |
| for intubated and mechanical ventilated male patients with normal lungs and normal chest wall movement, compliance varies from _____-_____ L/cmH2O, up to 0.1 L/cmH2O | 0.04-0.05 |
| for intubated and mechanical ventilated female patient with normal lungs and normal chest wall movement, compliance varies from ____-_____ L/cmH2O, up to 0.1 cmH2O | 0.035-0.045 |
| compliance is usually measured under conditions of no gas flow, it is referred to as _______ compliance | static |
| to obtain a static compliance, a _______ pressure is measured at static (no flow); also, the exhaled tidal volume from the patient's lungs is measured | plateau |
| static compliance represents | lung and thoracic compliance |
| calculations for static compliance (Cs) | Vt / plateau - eep |
| this is done during air movement | dynamic compliance |
| dynamic compliance represents | lung and thoracic compliance and airway resistance |
| calculation for dynamic compliance (Cd) | Vt / PIP - eep |
| normal resistance in a conscious patient is ____-____ cmH2O/L/sec | 0.6-2.4 |
| with artificial airways in place, normal Raw is _______ | increased |
| the smaller the ET tube, the greater the _____ | Raw (airway resistance) |
| Raw in intubated patients is around ___ cmH2O/L/sec | 6 |
| some diseases such as _____ or ______ can increase Raw | asthma or emphysema |
| calculation for airway resistance (Raw) | (PIP-Plat) / flow |
| attempts to mimic the actual function of the respiratory muscles to allow breathing through normal physiological mechanisms | negative pressure ventilation |
