A 49-year-old postoperative patient is on the following ventilator settings:
SIMV
Ventilator rate - 6/min
Tidal volume - 600 mL
FiO2 - 0.40
Peak flow - 60 L/min
Pressure support - 24 cmH2O
A weaning trial is started with the patient being placed on a T-piece. The patient
becomes tachypneic and short of breath, and must be placed back on the ventilator.
Based on this information, the RT should recommend which of the following?
A. Increase the peak flow
B. Increase the FiO2 to 0.50 while on the T-piece
C. Decrease the pressure support to 10 cmH2O
D. Increase the tidal volume to 650 mL
Give this one a try later!
, Decrease the pressure support to 10 cmH2O
The following data is collected on a 60 kg (132 lb) female receiving VC ventilation.
SIMV
Ventilator rate - 12/min
Total rate - 24/min
Tidal volume - 500 mL
FiO2 - 0.50
Pressure support - 10 cmH2O
PEEP - 5 cmH2O
ABG
pH - 7.48
PaCO2 - 30 torr
PaO2 - 57 torr
HCO3 - 23 mEq/L
BE - -2 mEq/L
Which of the following ventilator changes are appropriate?
A. Increase the PEEP to 8 cmH2O
B. Decrease the tidal volume to 450 mL
C. Decrease the SIMV rate to 8/min
D. Increase the FiO2 to 0.70
Give this one a try later!
Increase the PEEP to 8 cmH2O
While administering IPPB you increase the patient's PIP from 15 cmH2O to 20 cmH2O.
This will increase the...
