In each blank, try to type in the
word that is missing. If you've
typed in the correct word, the
blank will turn green.
If your not sure what answer should be entered, press the space bar and the next missing letter will be displayed. When you are all done, you should look back over all your answers and review the ones in red. These ones in red are the ones which you needed help on.

Question: Equipment for a pulmonary catheter?Answer: bedside cardiac monitor, pressurized saline bag, pressure amplifier/monitor, BTFD catheter, pressure system. Question: Equipment needed for an arterial line ?Answer: arterial catheter, flush device, hepranized saline bag, transducer, 4x4 squares, lidocaine, betadine/alcohol, tape to secure. Question: What is your hepranized bag placed at and what is the rate of your drip?Answer: to 300 torr and set to drip 2-4ml per hour. Question: Thermodilution method for QT?Answer: dextrose or saline injected at room temp into the proximal port of pulmonary cath. measures heat loss in relation to blood flow. done several times to get and . Question: Fick for measuring QT?Answer: requires I and E gases as well as mixed, gold standard, but used. Question: Contour C.O. monitoring?Answer: simultaneous measurements of art pressure and C.O. by methods for a baseline. If art prssure goes up them C.O. will go up. Question: C.O. monitoring?Answer: central venous blood used. If C(a-v)O2 is up then C.I. will be down and vice . Keep sats above 95%. Question: SVR? Answer: Systemic Vascular Resistance- pressure on the vessel's the body (from aorta). Question: PVR?Answer: Pulmonary Vascular Resistance- pressure on the artery Question: Discuss vascular ?Answer: component of afterload determined by (compliance of vessel), size (radius), viscosity (how thick), changes in pressure (from one end of vessel to the other). Question: Discuss Ejection ?Answer: fraction of end diastolic volume ejected with each beat. EF=SV/EDV. <30% tolerance severly limited. Question: EDV?Answer: End Volume- amount of blood before the contraction. Preload, or systole. Question: ESV?Answer: End Volume- amount of blood after the contraction. Afterload or diastole. Question: Cardiac Work?Answer: energy the heart uses to eject blood against the aortic or pulmonary . Correlates with O2 requirments of heart. L ventricle has to work 6X harder then the R.

Question: factors that affect contractility of the heart?Answer: coronary blood flow, sympathetic stimulation, Inotropic drugs, Physiologic depressants, damage to heart. Question: Discuss ability of the heart?Answer: HR and Question: Index ?Answer: based on body size. Question: Left filling pressures?Answer: preload and Question: atrial filling pressures?Answer: amount of blood in R atrium or Question: What do do these reflect: CVP, PAP, PWP, C.O.?Answer: CVP- R heart, fluid management; PAP- , mixed venous blood; PWP- L heart; C.O. blood pumped in one minute. Question: LCWI?Answer: amount of work on the left side of . Question: RCWI?Answer: of work on the right side of the heart. Question: Discuss ?Answer: directly related to SVR, mass, viscosity. Question: RVSWI?Answer: related to PVR, myocardial mass, viscosity. Question: Both and RVSWI increase with?Answer: , hypoxemia, and poor contractility. |
