A 6’3″, 180 lb male patient is being mechanically ventilated in the control mode with FIO2 .6, a set rate of 8, and a tidal volume of 800 ml. Peak airway pressure is 33 cmH2O. Breath sounds are diminished. Results of an arterial blood gas analysis are below. A desired PaCO2 of 40 is ordered. pH = 7.28PaCO2 = 83HCO3 = 21 mEq/LPaO2 = 75 torrSaO2 = 93% On the basis of these results, the most appropriate action would be to: I. increase the peak flow rateII. increase the set rate to 16III. increase the set rate to 20IV. increase the tidal volume to 900 ml

A 1.25 dm3 (1 dm3 = 1 L) cylinder contains 2.4 g of unknown gas. It is at 249 K and 0.44 atm. What is the molecular mass? Answer in g/mol. Do not type units. Do not use scientific notation.

A full size H oxygen cylinder contains how much pressure?

Remember to do Learning Commitment Chapter 9 as soon as possible (due 20 July). Remember to take the final on Wednesday during class time.

How does the pressure change as the following gas phase reaction progresses from reactants to products? You have to balance the reaction first.  __NH3(g) + __H2O2(g) –> __N(g) + __H2O(g)
