Q

Copd-

Use caution with what in these patients?

A

Oxygen - should not exceed 3L due to them retaining too much CO2 which could suppress their respiratory drive (lose of natural stimulus for respiration) instead of elevated CO2

Be careful giving narcotics - could suppress oxygen

Q

A circulatory condition in which narrowed blood vessels reduce blood flow to the limbs.

It is a sign of fatty deposits and calcium building up in the walls of the arteries (atherosclerosis).

Risk factors include aging, diabetes, and smoking.

Also a risk factor for PAD

involves damage to or blockage in the blood vessels distant from your heart—the peripheral arteries and veins.
