CVP is a good reflect of _________? What is normal CVP? __________ What is normal PAP? __________ A patient with a PE would have a low PAP pressure.   T or F

Anatomically, where should a pulmonary artery catheter be placed to measure PCWP?

Which patient would most likely be prescribed sodium nitroprusside ?

The purpose of linear regression is to: 

Two methods are compared for a method validation.  There are 20 concordant pairs of results and 5 discordant pairs of results between the two methods.  What is the test-retest reliability? (C-D)/(C+D)  (20-5)/(20+5) = 

Control values are running outside the acceptable range of a stable analyzer for the last 5 days.  The scientist in charge has troubleshooted possible causes and has discovered that the pipette used in the reconstitution of the controls needs calibration.  This represents an error in which phase of laboratory analysis?

An instrument has a probe error in the middle of running QC.  Both the low and high controls are outside acceptable limits.  This represents an error in which phase of laboratory analysis?

The sum of squares includes all of the following components, except: 

A patient is receiving mechanical ventilation with a fractional inspired oxygen (FIO2) of 0.85 and a positive end-expiratory pressure (PEEP) of 5 cm H2O. His arterial partial pressure of oxygen (PaO2) is 68 mm Hg, arterial oxygen saturation (SaO2) is 88%, and partial pressure of end-tidal carbon dioxide (PetCO2) is 32 mm Hg. Over the next few minutes his PEEP is titrated resulting in the following data: Time FIO2 PEEP (cm H2O) SpO2 (%) PetCO2 (mm Hg) 0600 0.85 5 88 30 0630 0.85 8 88 30 0650 0.85 10 90 32 0720 0.80 12 93 34 0740 0.80 15 90 25 what action should the respiratory therapist take at this time?
