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. 

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. 

Reaction steps that are far from equilibrium are good control points in metabolic pathways because:

The MOST sensitive indicator of the energetic status of the cell is the concentration of:
