Ventilator workshop Flashcards
information from ventilator workshop during ICP
When in volume control, if you increase RR, while leaving TV and I:E constant, what happens?
- increase inspiratory flow
- increase PAP (less time to get same TV in)
- may decrease patients actual TV
When in volume control, happens to pressure waveform if you increase RR (while leaving TV and I:E constant)?
- increase slope
2. more narrow
When in volume control, on the settings) if you decrease RR, while leaving TV and I:E constant, what happens?
- decrease inspiratory flow
2. decrease PAP (more time to get TV in)
In volume control, if you decrease I:E ( ex 1:1), while leaving TV and RR constant, what happens?
- increase I time (more time for inspiration)
2. decrease PAP
In volume control, if you increaes I:E ( ex 1:4), while leaving TV and RR constant, what happens?
- decrease I time (more time for exhalation)
2. increase PAP (less time to get same TV in)
When in pressure control, when you increase RR, while leaving PIP and I:E constant, what happens?
- decrease TV (less time for breath to diffuse)
When in pressure control, when you decrease RR, while leaving PIP and I:E constant, what happens?
- increase TV
When in pressure control, when you increase I:E ratio, while leaving PIP and RR constant, what happens?
1.decrease I time
2 decrease TV
3.shorter plateau pressure time
When in pressure control, when you decrease I:E ratio, while leaving PIP and RR constant, what happens?
- increase I time
- increase TV
- longer plateau pressure time
When comparing same plateau pressures in volume control to pressure control, what is expected?
TV in pressure control is slightly higher than TV in volume control
When using pressure support ventilation, how to trigger parameters effect the effort of breathing for the patient?
low trigger = any patient effort will trigger
higher trigger = stronger breath needed
