The RT is preparing to convert a patient from volume control to pressure control ventilation on a PB 840 ventilator. While in VC, the RT obtains the following values:            Vt 650 mL        Flow 50 Lpm      PIP: 34 cmH2O     Pplat: 29 cmH2O       PEEP: 11 cmH2OBased on these values, what is the appropriate Pinsp (delta P) for this patient in PC?

During management of a 27 yo asthmatic (55 Kg IBW) admitted to the pulmonary ICU due to status asthmaticus, you note that the patient has a low peak expiratory flow and long expiratory flow time. The patient has been receiving inhaled beta 2 adrenergic agents via continuous nebulizer for 3 hours. What should the RRT recommend to increase expiratory time (Te)? Increase inspiratory flow Change to a constant flow pattern Increase the set frequency Increase the set PEEP

I understand that I cannot discuss questions from the exam with other students until the exam has closed for everyone. 

A 40 year old patient recovering from ARDS is receiving mechanical ventilation with an IBW is 72 Kg. The following information is gathered: PaCO2= 43 torr, PaO2= 79 torr, PECO2= 22 torr, f= 15 bpm, Vt= 650 mLCalculate the patient’s physiologic deadspace in a single breath mL.
