A patient with muscular dystrophy currently receiving ventilatory support with VC-IMV is being prepared for discharge home
The case manager asks the respiratory therapist to recommend a ventilator that will meet the pa-tient's needs with the least complexity and at the lowest cost. The respiratory therapist should recommend which of the following ventilators?
a. PLV 102
b. LP-6 Plus
c. LTV 1000
d. Lifecare PLV 100
ANS: C
The LTV 1000 is the most appropriate choice, because SIMV is incorporated into the ventilator, and the associated WOB is lower than that of the first-generation ventilators (PLV 102, LP-6 Plus, and Lifecare PLV 100). This is important because this patient has a neuromuscular disease and may not be able to endure an increased WOB. Also, because the first-generation ventilators listed do not have internal IMV capabilities, an external H-valve assembly would have to be at-tached. This means additional equipment with increased complexity and possibly a higher cost compared with the second-generation ventilator (LTV 1000).
