Cardiac 06 Cardiogenic Pulmonary Edema

Question 1

What occurs during cardiogenic pulmonary edema?

Answer 1

It’s when there’s a result in increase of hydrostatic pressure within the pulmonary capillary bed as a result of HEART FAILURE.
Causes could be: HF, MI, MR, Tamponade, dysrhythmia, HTN crsis

Question 2

How do you differentiate between ARDS and cardiac pulmonary edema?

Answer 2

In cardiac there more silhouette to heart, fluid at bases of lung and in lung. Xray may show spider vein lines. The fluid is in the vessels of lungs.
In ARDS, fluid still in alveoli.

If you give lasix to both these pt, the cardiac pulmonary edema x ray would improve. NOT in ARDS because fluid is in alveoli which we can’t remove.

Question 3

What is the PAOP/wedge pressure a reflection of?

Answer 3

microvascular hydrostatic pressure.

Question 4

Number one cause of non cardiogenic pulmonary edema?

Answer 4

Sepsis, shock,sirs..

Question 5

What is pulmonary artery catheter useful for?

Answer 5

In evaluating cardiac and pulmonary pressures.

Question 6

How would you treat cardiogenic pulmonary edema?

Answer 6

1. diuretics
2. analgesic
3. preload reduction (nitro)
4. O2
5. afterload reduction if sBP >100 mmHg
6. Vasoconstriction if hypotensive

Question 7

How would you treat ARDs?

Answer 7

• tx underlying cause
• block specific mechanism of alveolar capillary
• minimize consequences of of ALI
