6
Q

How do the kidneys compensate with CHF and why

A

The kidneys aren’t getting enough blood, so they think the body is dehydrated
They stimulate the renin-angiotensin-aldosterone and ADH system
That results in fluid and sodium retention and fluid overload (central and peripheral) EDEMA

Q

What happens to the ventricles when preload increases (volume overload)

Q

List the steps in cycle resulting from poor cardiac function and fluid accumulation in the lung with hypoxemia

A

Acute LV systolic Dysfunction
Decreased myocardial contractility and CO
Catecholamine production (increases HR and BP)
Increase in SVR (Afterload) and BP
Increased myocardial wall tension and O2 demands
Leads to diastolic dysfunction, increased pulmonary artery and capillary hydrostatic pressures, hypoxia, and increases myocardial ischemia

Q

Summarize 1st, 2nd, and 3rd degree heart blocks

A

1st degree: A p-wave is being conducted but slower than we would want. This is ok because every signal is making it through at a predictable manner, so no tx.
2nd degree: Most P-waves are being conducted
2nd degree Type I: QRS is dropped due to progressive elongation of PR intervals. This is in a predictable manner, so not as concerning. Tx is Atropine and Pacer
2nd degree Type II: QRS is dropped randomly, PR intervals are all the same size. Random pacing means poor perfusion. This needs to be tx with a pacer
3rd degree heart block: No p-waves are making it through, meaning conduction system is relying on AV node or ventricles, which is too slow to perfuse appropriately. Tx is pacer
