what are the lymph nodes

Inguinal, cubital, axillary, subclavicular, cervical, submandibular

how many

curves

what do the leads do?

black - electrical ground (housekeeping) collect data from red and white

white - right arm measuring electrical activity in the right atrium

red - left arm measuring electrical activity in the left atrium

a segment is what?

straight

what do ions do ?

they move in and out at the same rate

what is a single cardiac cycle ?

RR interval that equals 1 beat

blood pressure is represented as what ?

systolic pressure over diastolic pressure

S/D

how do I get pulse pressure ?

systolic pressure - diastolic pressure

What is MAP?

Mean Arterial Pressure

How do you get MAP?

pulse pressure/ 3 + diastolic

Sphygmomanometer

used to put pressure on the brachial artery in the arm

auscultation is a

indirect measure of blood pressure

when does the turbulence occur ?

when the brachial artery is compressed and heard

whats happening during the first squirt of blood ?

systolic pressure

whats the first sound ?

systolic pressure

whats the last sound ?

diastolic pressure when ventricles relax

why do korotkoff sounds happen ?

Turbulence in blood flow when the brachial artery is partially closed

when does korotkoff sounds occur ?

regular intervals which starts and end with both pressures

Sounds are only heard when ?

Between systolic and diastolic pressures

If the pressure is above systolic pressure

The vessel is closed and has no turbulence

If the pressure is below diastolic

The vessel is

extra tissue in the lungs

Effect on lung volumes
