Question | Answer | |||
---|---|---|---|---|
This mode enables a patient to achieve large minute volumes, because every breath is mechanical, whether patient triggered or time triggered. | Assist-Control | SIMV | PSV | PCV |
Used to augment spontanous tidal volumes in SIMV or CPAP. | Pressure Support | PEEP | Flow-Volume Loop | Peak Flow |
May cause cardiovascular side effects such as hypotension in high amounts. | Sensitivity | |||
Increasing this can help recruit alveoli. | ||||
A time triggered breath is a _______ breath. | Mechanical | Spontaneous | Volume-controlled | Pressure-controlled |
If a breath is _________, it's volume will vary based on compliance. | ||||
In most situations, which is an appropriate sensitivity? | 2-3 | 6 | 10 | 0.2 |
The nbrc recommends increasing peep once fio2 is increased to ___% | 50 | 60 | 75 | 80 |
Minute volume is... | Pao2/fio2 | Not measurable | Vt/rr | Vt x rr |
Increasing peak flow will do all the following EXCEPT: | Improve air hunger if present. | Change I:E ratio | Increase peak pressure | Increase I time |
