When we use a stethoscope and blood pressure cuff to determine blood pressure, we place the diaphragm of the stethoscope over which blood vessel?
brachial artery
We demonstrated a couple different methods for determining blood pressure in lab X. One method that we did not use entails placing a catheter into the subject's brachial artery at the level of the heart. This is a very accurate way to measure blood pressue and is is called the _____________________________________________________________ method for determining blood pressure.
direct method

during late filling of the ventricle when the atria contract
The third heart sound would occur when during the cardiac cycle?
early filling of the ventricles right after the AV valves open
We demonstrated a couple different methods for determining blood pressure in lab X. Taking a subject's blood pressure using a blood pressure cuff and sphygmomanometer and noting when the pressure in the cuff started to fluctuate (which could cause the needle to bounce) is called the _____________________________________________________________ method for determining blood pressure.
indirect-oscillometric
When we take a subject's blood pressure by inflating a blood pressure cuff and feeling for their radial pulse, we call this the ___________________________ method for determining blood pressure.
indirect-palpatory
When we use a stethoscope and blood pressure cuff to determine blood pressure, what is true of the first sound we hear?
it is called the first Korotkoff sound

it occurs when the pressure in the ventricles falls below the pressure in the aorta
What does the 5th Korotkoff sound sound like?
no sound
Which heart sound is associated with closing of the semilunar valves?
second
If observed, when does the 3rd heart sound occur relative to our other heart sounds?
shortly after S2
The first Korotkoff sound is associated with:
systolic blood pressure
