Technique of reversing length of inspiration:expiration from 1:2 to 2:1
- increases the time for positive-pressure inspiration
- what clinical scenarios would this be beneficial?
- decreased expiratory time can lead to permissive hypercapnia and reduce barotrauma
Consequence of this type of ventilation:
- positive intra-thoracic pressure can result in decreased pre-load
- can be uncomfortable and cause anxiety for pt (requiring increased sedation)
- may not allow for adequate expiratory time resulting in stacked breaths and auto-PEEP
