Diminished or interrupted flow of blood through peripheral arteries can eventually lead to ischemic necrosis and gangrene. Sluggish venous flow leads to increased pressure within the vessels, causing varicose veins and sometimes thrombophlebitis. When blood is not moved out of the veins of the lower limbs, it accumulates there and serves as an excellent medium for bacterial growth and contributes to the formation of leg ulcers. Treatment is aimed at improving blood flow by removing or mitigating the cause of impaired circulation.
Assessment includes noting the color and temperature of the skin in the affected areas and any signs of trophic changes. Epidermoid tissues that are chronically malnourished because of poor blood supply appear shiny, smooth, and thin, with little or no hair on the surface. The nails are thick, with deposits of cornlike material under them. With time, a decreased blood supply produces ischemic changes that cause the skin to assume a purple-black color that is characteristic of cyanosis and gangrene. Additional assessment data include the rate, rhythm, and force of the peripheral pulses.
anemiaHematology A condition characterized by ↓ RBCs or Hb in the blood, resulting in ↓ O2 in peripheral tissues Clinical Fatigability, pallor, palpitations, SOB; anemias are divided into various groups based on cause–eg, iron deficiency anemia, megaloblastic anemia–due to ↓ vitamin B12 or folic acid, or aplastic anemia–where RBC precursors in BM are 'wiped out'.

Patient discussion about peripheral
Q. I am interested in finding info on Peripheral neuropathy and its symptoms. I wonder if I have it. I have restless leg syndrome discovered via a sleep clinic. A small tingling area developed in my back about 8 years ago. Nothing was disclosed to me about it and it progressed further up the back. I now wake up some nights with what I describe as left shoulder knot that makes left arm tingle and feel numb. Sometimes also goes down through to the left leg. It makes me feel jumpy and have trouble getting back to sleep. I rub Benyln on shoulder and take Tylenol. I eventually fall back to sleep. I do not have a family Dr. as she closed her practice and I must now visit walkin clinics. A stress test was recently done as I was having chest pain. Dr. thinks it's due to my Acid Reflux. HELP!
about neuropathy- as i recall (and i could be wrong here), in most cases it's a symptom that something cause. your nervous system usually don't just shut off with no reason.
