Which of the following is a normal response to excess loss of body heat in a cold environment?  

A 75-year-old, 5-foot, 7-inch female patient with an exacerbation of COPD is placed on the following NPPV settings: IPAP = 8 cm H2O, EPAP = 4 cm H2O, rate = 12 breaths/min, FIO2 = 0.3. The resulting VT is 255 mL. An arterial blood gas sample is drawn 1 hour later, and the results are: pH = 7.33, PaCO2 = 70 mm Hg, PaO2 = 58 mm Hg, HCO3- = 35 mEq/L. What action should the respiratory therapist take at this time?

Calculate the volume lost if the tubing compression factor is 2.5 mL/cm H2O and the pressure change during ventilation is 32 cm H2O.                                           2:6:2

What are the 3 levels of understanding in science?

When initially setting up a ventilator the plateau pressure (PPlateau) is measured at 47 cm H2O with a set volume of 100 mL. After applying the ventilator to the patient, the average peak pressure reached during volume delivery is 28 cm H2O. How much volume is lost in the ventilator tubing?                                             2:6:2
