MCRT- lung inflation
Key Terms
| Question | Answer |
|---|---|
| atelectasis | abnormal collapse of distal lung parenchyma |
| continuous positive airway pressure (CPAP) | method of ventilatory support whereby the patient breathes spontaneously without mechanical assistance against threshold resistance, with pressure above atmospheric maintained at the airway throughout breathing |
| intermittent positive airway pressure breathing (IPPB) | application of positive pressure breaths to a patient for relatively short period of time (10 to 20 minutes) |
| incentive spirometry (IS) | the process of encouraging the bedridden patient take deep breaths to avoid atelectasis; most often done with use of an incense barometer that provides feedback to the patient when a predetermined lung volume is reached during and inspiratory breath |
| lobar atelectasis | alveolar collapse involving a specific lobe of the lung |
| passive atelectasis | collapse of distal in lung units due to persistent ventilation with small tidal volumes |
| positive expiratory pressure (PEP) | airway clearance technique in which the patient exhales against a fixed orifice flow resister in order to help move secretions into the larger airways for expectoration via coughing or swallowing |
| resorption atelectasis | collapse of distal lung units due to mucous plugging of airways |
