Create a matrix of hemodynamic values including systemic blood pressure, central venous pressure, pulmonary artery pressure, pulmonary wedge pressure, mean arterial pressure, right atrial pressure, right ventricular pressure, left atrial pressure, stroke volume, cardiac output, systemic vascular resistance, and pulmonary vascular resistance, indicating for each the following data: normal values, causes of increased values, and causes of decreased values.
parameters | normal value | high value | causes for increased value | low value | causes of decreased value |
1-blood pressure- systolic bp |
<120mmHg | <130 |
-obesity heart valve problem -diabetes -hyperthyroidism |
<90 |
-pregnancy -blood loss -dehydration -infection -anaphylaxis |
diastolic BP | <80 | >85 |
-obesity -lack of physical activity -high sodium diet-alcohol |
<60 |
-Parkinsons disease -infection -anemia -allergic reaction |
central venous pressure-CVP | 2-6mmHg | >6 |
-overhydration -positive pressure breathing -decreased contractility -valve abnormalities |
<2 |
-hypovolemia -negative pressure breathing - |
pulmonary artery systolic pressure, | 15-25mmHg | >25mmHg |
-idiopathic pulmonary arterial hypertension -genetic mutation-drugs or illegal drugs -HIV -congestive heart failure Congestive heart failure |
<15mmHg |
large cross-sectional area of the pulmonary circulation -anaphylaxis |
pulmonary artery diastolic pressure, | 8-15mmHg | 15>mmHg |
-pulmonary artery diastolic pressur -flow is abolished |
<8mmHg |
hypovolemia -shock -sepsis |
pulmonary wedge pressure | 4 to 12 mm Hg | >12 mm Hg |
-left ventricular failure -mitral or aortic valve disease. -cardiac insufficiency -post hemorrhage |
<4 mm Hg |
-copd -pulmonary venous obstruction -atrial myxoma |
mean arterial pressure |
70 and 100 mmHg | >100 mmHg |
- heart attack -kidney failure -heart failure |
<70 mmHg |
- sepsis -stroke -internal bleeding |
stroke volume | 50 to 100 ml | >100 ml |
-An increase in the volume -the speed of venous return will increase preload |
>50 ml | -Decreased venous return |
cardiac output | 5 to 6 liters | >6 liters |
|
<5liters |
myocardial infarction -hypertension - valvular heart disease - congenital heart disease cardiomyopathy -heart failure -pulmonary disease, |
pulmonary vascular resistance |
100 – 200 dynes/sec/cm-5. | >200 dynes/seconds/cm-5 |
|
<100 dynes/seconds/cm-5 |
low SVR -septic shock |
systemic vascular resistance | 700 to 1,500 dynes/seconds/cm-5. | >1,500 dynes/seconds/cm-5 |
|
<700 dynes/seconds/cm-5 |
