CH. 30 BLEEDING Flashcards
the pressure in the aorta against which the left ventricle must pump blood; increasing this can decrease cardiac output
afterload
the fluid tissue that is pumped by the heart through the arteries, veins, and capillaries and consists of plasma and formed elements or cells, such as red blood cells, white blood cells, and platelets
blood
amount of blood pumped by the heart per minute. Calculated by multiplying the stroke volume by the heart rate per minute
cardiac output (CO)
the early stages of shock, in which the body can still compensate for blood loss. The systolic blood pressure and brain perfusion are maintained
compensated shock (classes I & II)
the late stage in shock, when blood pressure is falling
decompensated shock (class III)
the percentage of blood that leaves the heart each time it contracts
ejection fraction (EF)
red blood cells
erythrocytes
vomited cells
hematemesis
passage of stools containing bright red blood
hematochezia
a blood test that measures the portion of red blood cells in whole blood
hematocrit
a mass of blood in soft tissues beneath the skin; indicates bleeding into soft tissues and may be the result of minor or a severe injury
hematoma
blood in the urine
hematuria
the oxygen carrying pigment in red blood cells
hemoglobin
lacking one or more of the blood’s clotting factors.
hemophilia
coughed up blood
hemoptysis
