Pulse pressure
the difference between the diastolic pressure and systolic pressure. Tells doctors the sustained pressure that an individual is under.
What other pressures can help clinicians?
Pulse pressure and mean arterial pressure
Pulse pressure= ____ - ______
systolic - diastolic pressure
MAP (mean arterial pressure) = ______ + ______
diastolic+ 1/3 pulse pressure
What is the traditional blood pressure?
120/80
Systolic pressure is the ____ pressure
highest
Mean arterial pressure
average arterial pressure (taken at several intervals or calculated by 1/3 pulse pressure)
We inflate the pressure in the cuff to what?
130
Hypertension
chronic high resting blood pressure. Systolic = higher than 140, OR diastolic = higher than 90
What is happening in the vesseks when we take blood pressure?
Blood cannot flow and is obstructed.
resistence to flow
blood viscocity (how thick the blood is), vessel length (how many vessels are in the system), vessel radius (how dilated the vessels are)
What are the three factors influencing blood pressure?
Cardiac output, blood volume, and resistence to flow.
What are the chronic blood pressure conditions?
hypertension and hypotension
Hypotension
chronic low resting blood pressure. Systolic= lower than 100 OR diastolic= lower than 60
Cardiac output:
the amoutn of blood ejected from the left ventricle over time
Why dont we hear our blood moving through our vessels?
Laminar flow: smooth, silent flow near the center of the vessel. Blood flows through the middle so we dont hear it.
The second sound you hear is the ______ pressure
diastolic
Blood volume
how much blood is in the system
The first sound you hear is which pressure?
Systolic
Diastolic pressure is the _____ pressure
Lowest
Blood pressure
The force that blood exerts against a vessel wall
What device is used to check blood pressure?
sphygmomenometer
Where should we measure blood pressure?
Brachial
Systolic pressure
is the top number; it gives increase in pressure and is the peak arterial BP attained during ventricular contraction (normal range is 100-140mmHg)
Diastolic pressure
minimal arterial BP attained during ventricular relaxation (normal range is 60-100mmHg).This is the number on the bottom.
