|---|---|---|---|---|---|
| Identifying marks for an arterial wave form? | show 🗑
|
||||
| show | small thin line, lower to the horizontal scale line.
🗑
|
||||
| show | waveform hits the top and the bottom of the scale.
🗑
|
||||
| Identifying marks for the PAP waveform? | show 🗑
|
||||

🗑
|
||||
| show | 4-12 torr
🗑
|
||||
| show | 2.5-4.5 L/min/m2
🗑

🗑
|
||||
| Normal value for Stroke volume? | show 🗑
|
||||
| Normal value for ejection fraction? | show 🗑
|
||||
| Discuss preload? | show 🗑
|
||||
| show | resistance that opposes ventricular ejection.
🗑
|
||||
| show | assemble equipment, perform Allen's test, drape pt, inject 1% lidocaine, catheter inserted 30 degree angle, hold needle and advance catheter, remove needle and secure, attach drip and observe waveform.
🗑
|
||||
| show | done by physician, check ballon for patency, inserted into selceted sight until reaches R atrium then inflate balloon with 1.5cc's.
🗑
|
||||
| Common sites for placing pulmonary catheter? | show 🗑
|
||||
| show | radial, brachial, or femoral.
🗑
|
||||
| Equipment needed for a pulmonary catheter? | show 🗑
|
||||
| Equipment needed for an arterial line placement? | show 🗑
|
||||
| show | pressurized to 300 torr and set to drip 2-4ml per hour.
🗑
|
||||
| Thermodilution method for measuring QT? | show 🗑
|
||||
| show | requires I and E gases as well as mixed, gold standard, but rarely used.
🗑
|
||||
| show | simultaneous measurements of art pressure and C.O. by other methods for a baseline. If art prssure goes up them C.O. will go up.
🗑
|
||||
| Estimated C.O. monitoring? | show 🗑
|
||||
| show | Systemic Vascular Resistance- pressure on the vessel's throughout the body (from aorta).
🗑
|
||||
| Discuss PVR? | show 🗑
|
||||
| Discuss vascular resistance? | show 🗑
|
||||
| show | fraction of end diastolic volume ejected with each beat. EF=SV/EDV. <30% exercise tolerance severly limited.
🗑
|
||||
| show | End Diastolic Volume- amount of blood before the contraction. Preload, or systole.
🗑
|
||||
| Discuss ESV? | show 🗑
|
||||
| show | energy the heart uses to eject blood against the aortic or pulmonary pressures. Correlates with O2 requirments of heart. L ventricle has to work 6X harder then the R.
🗑

🗑
|
||||
| show | amount of blood in R atrium or CVP
🗑
|
||||
| What do parameters do these reflect: CVP, PAP, PWP, C.O.? | show 🗑
|
||||

|
||||
| show | directly related to SVR, mycardial mass, viscosity.
🗑
|
||||
| Discuss RVSWI? | show 🗑
|
||||
| Both LVSWI and RVSWI increase with? | show 🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
