what type of breath occurs when the vent controls the timing, tidal volume, or insp. pressure?

Mandatory

a home care pt diagnosed with CSA would benefit from which of the following modes of vent?

NIV

during volume control ventilation a pts airway resistance causes increases. this change will cause which of the following to occur? 

increase in peak airway pressure

a 28 yr old male has arrived on the ED following a MVC. he has a Glasgow coma score of 14. CXR reveals 5 rib broken anteriorly in two areas each. assessment shows: paradoxical movement of chest, BS diminished and the trachea is midline, PH 7.53, CO2 25, O2 59, HCO3 23. what should we recommend?

CPAP with supplemental O2

An assisted breath in the PC-CMV mode can be described by which of the following?

the ventilator mode that allows the pt to breathe spontaneously between operator selected time triggered volume and pressure targeted breaths is which of the following?

IMV

a hemodynamically unstable pt being vent in the VC-CMV mode is triggering inspiration at a rate of 25 bpm and has an ABG: 7.50/30/98/24. what should we perform?

VC-IMV

full vent support is provided by which of the following modes?

PC-IMV with PS

the vent mode that would be most appropriate to iatrogenically induce hyperventilation to manage a closed head injury pt with severe elevated ICP is which of the following?

PC-CMV

if flow or sensitivity is set incorrectly, which of the following is most likely to occur during the CMV mode

ventilator desynchrony

in which situations would NIV be tried?

pt with COPD and right lower lobe pneumonia and increased WOB

a breath that is triggered limited and cycled by the MV is which of the following?

mandatory breath

a breath that is pt triggered and time triggered is which of the following?

assisted breath

a pt riggered, pressure limited, flow cycled breath describes which of the following?

PS

when a pt is to be switched from CMV to IMV to facilitate weaning from MV which of the following could be used in addition to IMV to assist this process?

PS

every breath from the vent is time or pt triggered, pressure limited, and time cycled, this describe which vent mode?

PC-CMV

if lung compliance decreases while pt is receiving MV with PC-CMV, which of the following would occur?

tidal volume will decrease

a pt with ARDS had developed pneumothorax from elevated peak and plateau pressure. the pt is currently being ventilated in the VC-CMV mode with a set rate of 12 bpm. however the pt is triggering the vent at a rate of 25 bpm. abg: vent induced hyperventilation with corrected hypoxemia. What should we recommend?

switch modes to PC-IMV

a pt who is nasally intubated due to facial injuries has been successful on her spontaneous breathing trial. she currently has moderate hypoxemia, despite a fractional FiO2 of 40% and PEEP of 5cm H2O while on VC-CMV. what most appropriate vent mode for this pt is which of the following?

IMV with PSV and PEEP

a dual control mode provides pressure limited vent with volume delivery targeted for every breath. if the desired is not met the vent will volume cycle. this described which of the following vent modes? 

Paug

the vent mode that delivers pressure breaths that are pt or time triggered, volume targeted, time cycled, and where the pressure is automictically adjusted to maintain delivery of the targeted volume in which of the following?

PRVC

the ventilator mode where every breath is pt triggered, pressure targeted, and flow cycled with a volume target is which of the following?

VSV

a leak around a pt ET tube cuff during PSV will cause which of the following to occur?

time cycle
