Shock

Question 0

Septic shock (2main)

Answer 0

Oxygenation and tissue perfusion

Question 1

Shock

Answer 1

Is a widespread abnormal cellular metabolism that occurs when oxygenation and tissue perfusion needs are not met to their level necessary to maintain cell function

Question 2

1 cause of death in the US in almost every year since 1900

Answer 2

Cardiovascular disease

Question 3

What 2 systems does the cardiovascular system work with to meet the human need for oxygenation and tissue perfusion?

Answer 3

Respiratory and Hematologic systems

Question 4

Leading cause of death for women?

Answer 4

CVD

Question 5

What heart muscle must receive sufficient oxygen to be able to pump blood to other parts of the body?

Answer 5

Myocardium

Question 6

How much does each beat of the heart pump?

Answer 6

60 mL of blood, or 5 L/ min

During strenuous exercise it can double the amount

Question 7

What is the heart covering called?

Answer 7

Pericardium

Question 8

Right atrium receives ?

Answer 8

Deoxygenated venous blood, returned from the body through the inferior vena cava. And receives blood from the heart through the coronary sinus

Question 9

Right ventricle

Answer 9

Muscular pump located behind the sternum–>generates enough pressure to to close the tricuspid valve–> open the pulmonic valve and propel blood into the pulmonary artery and the lungs

Question 10

What cardiac valves are responsible for maintaining forward flow of blood through the heart chambers?

Answer 10

AV– atrioventricular valves

SV– semilunar valves

Question 11

The AV valves

Answer 11

Separate the atria from the ventricles

Question 12

What are bathe AV valves called?

Answer 12

Tricuspid valve separates the RA from the RV
Mitral valve (bicuspid) separates the LA from the LV

Question 13

What do the tricuspid- mitral ( bicuspid) valves do?

Answer 13

During ventricle Diastole, these valves act as funnels and help move the flow of blood from the atria to the ventricle.

During systole, the valves close to prevent back flow into the atria

Question 14

What are the Semilunar valves?

Answer 14

Pulmonic valve separates the right ventricle from pulmonary artery

Aortic valve separates the left ventricle from the aorta

Question 15

After blood is reoxygenated what does it do?

Route and during systole and diastole

Answer 15

It flows freely from the four pulmonary veins into the left atrium, then through a open mitral valve into the left ventricle during ventricular Diastole. When the left ventricle is almost full the left atrium contracts, pumping the remaining blood into the left ventricle.

With Systolic contraction, the left ventricle generates enough pressure to close the mitral valve and open the aortic valve. Blood is propelled into the the aorta and into the systemic arterial circulation.

Question 16

To maintain adequate bold flow through the coronary arteries what must happen?

Answer 16

Mean arterial pressure (MAP) must be at least 60-70 mmHg. This is necessary to maintain perfusion of major body organs, such as the kidney and brain.
