Question 1

how does pneumonia cause cyanosis?

Accepted Answer

Cyanosis: Cyanosis is the low level or lack of oxygen.  Pneumonia makes the exchange of oxygen in the lungs difficult.  One who has pneumonia often finds their oxygen level too low or cyanotic.

Question 2

what causes a brief episode of cyanosis with palpitations and tingling ?

Accepted Answer

Heart: These symptoms suggest a sudden and serious restriction of blood flow from a heart-related problem.  See your physician or cardiologist soon.

Question 3

can a lesion in the thecal sac at l4 somehow cause cyanosis or blueness in the feet that quickly resolves when the feet are elevated?

Accepted Answer

No: See your doctor and get clarification this is not from the thecal sac. This sounds more like blood pooling and  acrocyanosis. The blood pools at the bottom of your legs and more oxygen is removed from the red cells therefore the blue color.

Question 4

can coarctation of aorta cause cyanosis? is cyanosis due to hypoxia?

Accepted Answer

Not in isolation: Coarctation only causes cyanosis when it is associated with other heart disease that allows blue blood to cross over to the red blood side.  Cyanosis occurs in two situations: 1. When blue blood gets to the red blood side ("right-to-left shunting) or 2. When blood is not fully oxygenated in the lungs ("pulmonary venous desaturation").

Question 5

cyanosis and freezing cold  after eating chocolate, sugar,wheat .possible causes?started in early twenties.fine as child.cannot eat these at all now.

Accepted Answer

Unclear - many choic: You need to discuss with your  physician and perhaps see  an allergist. We consider diagnoses such as Gluten, chocolate  allergy, etc. As a food allergy it is  complex  to diagnose as there  may be no clear tests.

Question 6

can cyanosis be caused by lung cancer? if so, how?

Accepted Answer

Cyanosis: Hello. Cyanosis is a physical sign that is characterized by a bluish/purplish coloration of skin or mucous membranes, that is caused because of a low oxygen saturation. So yes, it can be caused by lung cancer, but there are a lot of other pathologies (mainly hearth and lung diseases) that can cause that sign.

Question 7

cyanosis from eating lima beans which causes glycosides to release cyanide on contact with stomach acid. is that an allergic reaction?

Accepted Answer

No: This is not an allergic reactions. Allergic reactions occur when the immune system overreacts to something that is normally harmless. Cyanide is a poison contained in some foods.

Question 8

i had respiratory failure (cyanosis) during general anaesthetic.the doctor thinks it was anaphylaxis.  i am now diagnosed with both copd stage 2 and asthma.were these conditions the more likely cause?

Accepted Answer

COPD is deadly: Anaphylaxis can happen with any drug, but acute postoperative respiratory failure is more commonly caused by underlying lung disease. Stopping smoking several weeks before surgery decreases risk for complications. Of course, the best thing anyone can do for better health is to stop smoking, especially those with lung disease. Smoking with lung disease is like rubbing dirt into a wound. Stop ASAP.

Question 9

4y/o w/ recurring fevers, joint pain, swollen lymph nodes, no appetite, cyanosis. has asthma but controlled. cbc shows 16% monocytes. possible cause?

Accepted Answer

Several possibles: There are numerous possible causes. You need to have this discussion with your pediatrician.

Question 10

non viral causes of high monocytes 16%? 4 y/o w/symptoms: recurring fever, cyanosis, joint pain, no appetite, swollen lymph nodes. fh of jra & lupus.

Accepted Answer

Not the key: As a pathologist and lab specialist, I would discourage you from paying any attention at all to percentages, or to monocytes unless the absolute count is well over 1000. Sounds like a JRA variant if it is clear there is no heart defect or endocarditis
