Term
|
Definition
| BF is normal but air mvmt is inadequate. Chest pressure change is inadequate. Co2 is retained |
|
|
Term
|
Definition
| Chest pressure adequate air moves without difficulty but pulmonary blood is not oxygenated suffiently. Lung blood flow is decreased. May be shunted and bypass lungs. Supplemental o2 does not help |
|
|
Term
| Pressure cycled ventilation |
|
Definition
| Pushes air into lungs until a preset airway pressure is reached |
|
|
Term
|
Definition
| pushes air into lungs until a preset time has elapsed |
|
|
Term
| Volume cycled ventilation |
|
Definition
| Pushes air into lungs until a preset volume is delivered. Delivered regardless of chest wall compliance or airway resistance |
|
|
Term
| Microprocessor ventilators |
|
Definition
| Computer managed. Better monitoring |
|
|
Term
|
Definition
Responds to pts inspiratiory effors and takes over the work of breathing for PT.
Can lead to hyperventilation and Resp alkalosis. Continues to deliver o2 at preste tidal volume even when spontaneous breathing increases |
|
|
Term
| Synchronized intermittent |
|
Definition
Preset Tidal volume and ventilatory rate.
Allows spontaneous breathing at PTs own rate and tidal volume between breaths |
|
|
Term
| Bi level positive airway pressure |
|
Definition
| Provides noninvasive pressure support ventilation by nasal mask or face mask. |
|
|
Term
|
Definition
Applies positive pressure throughout entire respiratory cycle for spontaneously breathing pts.
Keeps alveoli open. Increases functional residual capacity. |
