Which of the formula will determine the total flow being
delivered to a pt with a 28% venturi mask running at 6
L/min? - Answer-Total flow = 6 x 11 (flow factor for 28% =
10:1 = 11)
A pt with end-stage pulmonary fibrosis is receiving O2 at
2L/min via a transtracheal oxygen catheter. The pt
experiences an increased WOB and shortness of breath.

significantly with a severe fall in the BP. Based upon the
above info, what should the RT conclude that the pt is
suffering from? - Answer-Hypovolemia
