Formed Elements of Blood
What is the hematocrit concept?
Ratio of red blood cells to the total volume of blood
How to interpret blood type results
if there is agglutination (clumping) it is positive for that blood type or the RH
What is the universal blood donor?
What is the universal acceptor of blood?
Never Let Monkeys Eat Bananas
what is the P wave of an EKG?
depolarization of the right and left atria
blood forced from atria to ventricle
what is the QRS complex of the EKG?
depolarization of the right and left ventricle
normally the ventricles are activated simultaneously
all valves are closed with ventricular depolarization
What is the ST-T wave of an EKG
what is the U wave of an EKG?
probably represents after depolarization in the ventricles, origin for this wave is not clear
What is the PR interval of an EKG?
time interval from onset of atrial depolarization (P wave) to onset of ventricular depolarization (QRS complex)
What is the QRS durationl of an EKG?
duration of ventricular muscle depolarization
What is the QT interval of an EKG?
duration of ventricular depolarization and repolarization.
What is the RR interval of an EKG
duration of ventricular cardiac cycle
an indicator of ventricular rate
What is PP interval of an EKG?
duration of atrial cylce
indicator of atrial rate
what is systolic pressure?
maximum pressure against the artery
measured in mmhg
what is diastolic pressure?
minimum pressure against the artery
measured in mmhg
What is Pulse pressure?
PP= systolic - diastolic
use it to find mean arterial pressure
What is Mean arterial pressure?
MAP = Diastolic + 1/3 PP
this tells you if your organs are all getting enough blood
basics of the Wigger diagram
where can pulses be felt in the body?
what 3 vessels drain into the right atrium?
superior and inferior vena cava and the coronary sinus
