|---|---|---|---|---|---|
| Blood pressure | a. Normal Systolic = 90-140
b. Normal Diastolic = 60-90
c. As BP increases CO & CI usually decrease
b. As BP decreases CO and CI usually increase
🗑

| Pulse Pressure | a. Systolic BP minus Diastolic BP
b. Normal = 40 mmHg
c. greater than 40 indicates decreased Stroke Volume (SV)
🗑
|

| SV (Stroke Volume): |
a. Cardiac Output divided by Heart Rate
b. Normal = 60 – 130 ml/beat
c. It's the volume ejected per beat
🗑
|
||||
| CO (Cardiac Output): | a. Heart Rate times SV
b. Normal = 4.8 LPM
c. More reliable than Mean Airway Pressure (MAP)
🗑
|
||||
| CI (Cardiac Index): | a. Cardiac Output divided by Body Surface Area (BSA)
b. Normal = 2.5 LPMm2 or simply CO/2
c. Decreased with shock, dehydration, cardiac fail, PE.
d. Increased with hypoxia, low BP.
e. More reliable measurement than CO.
🗑
|

| EF(Ejection Fraction): | a. % of blood volume pushed out of heart per beat.
b. Normal = 65 – 75%
c. Reduced with ventricular damage
🗑
|
||||
| MAP (Mean Arterial Pressure): | a. systolic BP + (Diastolic*2)/3
b. Normal = 70 – 105
🗑

| Define Preload | Blood that returns to ventricles at end diastolic, & refers to stretch of myocardial fibers after it is filled with blood.

| PCWP (Pulmonary Capilary Wedge Pressure | 1. Measures left heart function
2. Normal = 5 – 12 mmHg (same as PAP diastolic)
3. greater than 18 = edema forming in lungs (if no signs CHF think ARDS)
4. greater than 25 = edema in lungs from left heart failure (CHF)
5. greater t

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.
