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.
