| Blood Pressure | Force exerted by the blood against the vessel wall
🗑
|
||||
| Cardiac Output | Amount of blood ejected from the heart per minute
🗑
|
||||
| Peripheral Resistance | Opposing force of the vessel against the blood; pertaining to the health and elasticity of the vessel
🗑
|
||||
| Stroke Volume | Amount of blood ejected from heart per contraction
🗑
|
||||
| Pulse Pressure | Numerical difference between Systolic BP and Diastolic BP
🗑
|
||||
| Blood Volume | Total amount of circulating blood
🗑
|

| Cardiac Output | Amount of blood ejected by the heart per minute
🗑
|

| Resistance | Opposing force of the vessel against the blood; pertaining to the health and elasticity of the vessel
🗑
|
||||
| Viscosity | Thickness of blood; ease with which blood flows through vessel
🗑
|
||||
| Hormones | ADH - Anti Diuretic Hormones (water retention) Aldosterone (ALST) - causes sodium retention (increase B.P.
🗑
|
||||
| Normal range of Systolic BP | anything from 80 - 120
🗑
|
||||
| Normal range of Diastolic BP | anything from 0 - 80
🗑
|
||||
| Blood pressure measured in what? | mmHg (millimeters of Mercury)
🗑
|
||||
| What method is used in obtaining BP using the stethoscope? | Auscultatory
🗑
|
||||
| What is meant by "Vital Signs"? | T - Temperature
P - Pulse (Heart Rate)
R - Respiratory
BP - Blood Pressure
🗑
|
||||
| Arteriosclerosis | Hardening, thickening and loss of elasticity (narrowing) of the arterial wall.
🗑
|
||||
| Phase I of Blood Pressure | Blood begins to trickle through. Begin to hear korotkoff sounds - systolic.
🗑
|
||||
| Phase II of Blood Pressure | Blood continues to flow. Bouncing off walls - korotkoff sounds continue. "swish" sounds in phase II sounds stop - "auscultatory gap" (this is not common)
🗑
|
||||
| Phase III of Blood Pressure | Everything continues - however - if you don't pump the cuff up high enough - you'll miss patients who have high blood pressure or 30-40-50- mm of mercury off. You could think the first sounds you hear (systolic) would be after the "auscultatory gap".
🗑
|
||||
| Phase IV of Blood Pressure | Sounds continue - softer - quieter
🗑
|
||||
| Phase V | Sounds stop - diastolic
🗑
