Disorders

Question 1

Right Ventricular dysfunction/failure secondary to pulmonary heart disease?

Answer 1

Cor Pulmonale = pulmonary heart disease.

Question 2

Acute Cor Pulmonale?

Answer 2

RV Dilation with no time to Adapt…PE.

Question 3

Chronic Cor Pulmonale?

Answer 3

RV Hypertrophy, +/- Dilation and time to adapt…pHTN.

Question 4

Equation for Cardiac Output?

Answer 4

CO = HR x SV

Question 5

Cardiac output is measured in?

Answer 5

Volume/minute

Question 6

What controls the Heart Rate?

Answer 6

ANS - Autonomic NS.

Question 7

3 things that modify the Stroke Volume (SV)?

Answer 7

Preload = end-diastolic blood volume
Inotropy = strength of ventricular squeeze
Afterload = the force the ventricle must pump against.

• *an increased afterload lowers SV and vice versa.
• *increased preload and inotropy increases SV.

Question 8

Pressures of the pulmonary circulation in healthy lungs?

Answer 8

Low pressure/afterload, Low vascular resistance, High compliance/Low elastance.

Question 9

Pressures of the systemic circulation in healthy lungs?

Answer 9

High pressure, High resistance, Low compliance/High Elastance.

Question 10

Cor Pulmonale occurs when RV afterload….

Answer 10

Increases
