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
