Question

The following data is available for a 54-year old male who is receiving volume-controlled ventilation:

Height 5 ft 8 in (172 cm) Weight 77 kg (169 lb)
Mode SIMV
Rate 4/min
Total rate 12/min
FIO2 0.40
VT (set) 550 mL
VT (spont) 410 mL
VC 1.8 L
MIP - 42 cm H2O
MEP + 65 cm H2O
Qs/Qt 12%
A-aDO2 112 mm Hg
Arterial blood gases are within normal limits.Based on this data, the respiratory therapist should recommend
A. discontinue mechanical ventilation
B. decrease mandatory rate to 2/min
C. order a V/Q scan
D. continue current therapy

Answer 1

Based on the data provided, the respiratory therapist should continue current therapy.

Step-by-step explanation:

Based on the data provided, it would be recommended for the respiratory therapist to continue current therapy.

The height, weight, and arterial blood gases of the patient are within normal limits, indicating a stable condition. The set tidal volume (VT) of 550 mL and spontaneous tidal volume (VT) of 410 mL are also within acceptable ranges. The mode of ventilation and other parameters are not indicating any need for changes in therapy.

In this case, there is no need to discontinue mechanical ventilation, decrease the mandatory rate, or order a V/Q scan.
