Which of the following is false about flow triggering of spontaneous breaths during mechanical ventilation?

a. Flow triggering lowers the patient's work of breathing.
b. Flow triggering is preferred for initiating spontaneous breaths.
c. Flow triggering reduces the work of breathing due to small endotracheal tubes.
d. Flow triggering results in better pa-tient-ventilator synchrony.

ANS: C
Flow triggering may not be effective in reducing work of breathing because of the presence of a small endotracheal tube or auto-PEEP.
