A patient is receiving mechanical ventilation on a Hamilton G-5 with the following settings:Mode: (S)CMV Vt: 500 mL                               Set rate: 12 bpm            Tot rate: 20 bpm            PEEP: 12 cmH2O         PIP: 35 cmH2O             Pplat: 32 cmH2O                      FiO2: 1.0                      Peak Flow: 60 LpmABGs:  pH 7.47, PaCO2 33, PaO2 55, HCO3 20CXR reveals diffuse, bilateral opacities. The patient’s lung compliance has been steadily decreasing. What ventilator recommendation would be most appropriate for this patient at this time?

Reed has been on a ventilator for 48 hours. The pressure-time tracing for three separate hours is shown below.  If tidal volume and flow remained the same, which of the following is/are true regarding the pulmonary mechanics for this patient?  

Explain the significance of non-covalent interactions in living systems.

Bronchospasm, mucosal edema, secretions, endotracheal tubes, tracheostomy tubes, ventilator demand flow systems, ventilator circuits, and increased ventilator inspiratory flow rates may all be causes of:

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.
