Decreased pulmonary blood flow alone does not cause cyanosis. It is when decreased pulmonary blood flow is associated with right to left shunting (ie Tetralogy of fallot) that it is associated with cyanosis.

Is there a connection to cardio-artery disease and pulmonary hypertension?
Pulmonary hypertension(P-h) is a syndrome that involves heart and lung. Diseases like COPD (chronic pulmonary disease) May also cause pulmonary hypertension. Not all the cardio-artery disease is related to P-h. Heart has valves. Dysfunction of these valves will cause tension to the blood flow, leading to p-h.
What heart disease causes cyanosis?
Is result of emberoylic defect that lead of right to left shunt
What problems does hole in the heart cause?
Blood being pumped out of your circulatory system and into your chest cavity
Why is an embolus dangerous?
They may cause death if they block a major artery, such as the large pulmonary artery that runs through the lungs. They also may cause tissue to die if they prevent blood flow to the area.
Should I worry about clogged arteries?
Yes, as these can cause clots that can break off and block blood flow to the heart muscle (heart attack), lungs (pulmonary emboli) or the brain (stroke).
Can pale progress to cyanosis?
It would depend on the cause of the paleness. Cyanosis is a blue tint to the skin which happens as a result of a lack of oxygen. So, unless the pallor is caused by a condition with decreased oxygen levels, it will not progress to cyanosis.
Can a blood transfusion cause a pulmonary embolus?
can
What can cyanosis cause?
Typically oxygen deprivation, but it is common it conditions like hypothermia and hypovolemic shock, where blood is shunted away from the skin to preserve the vital organs. Another cause in neonates is a congenital heart defect known as tetrology of fallot, where venous blood is shunted back through the systemic circulation instead of the pulmonary circulation.
How decreased blood supply effect muscle activity?
Decreased blood supply in the muscle can cause anoxia then paralysis.
Can we cure a cyanosis?
yes cyanosis is usually curable but the cause of cyanosis may not be (e.g. active dying).
In lung cancer there are frequent tumers in the lymphatic tissue. These may reduce the flow in the pulmonary arteries. What impact would this have on the respiratory system?
The pulmonary arteries are responsible for carrying deoxygenated blood to the lungs so decreased flow would cause an increase in the amount of carbon dioxide in the blood, which in return can increase hydrogen ion concentration. This can produce acidosis of the blood.

Why do sick people need pure oxygen?
the oxygen level in blood should be above 98% to 100% for a human to be able to breath . any level lower than that will cause cyanosis ( high co2 in blood) to avoid cyanosis when needed medically we provide pure o2
The hypoxia associated with high altitude can cause?
vasoconstriction of the pulmonary blood vessels
Can decreased calcium in the blood cause muscle spasms?
Yes, when severe.
What is idiopathic pulmonary arterial hypertension?
Primary pulmonary hypertension is generally classified as a disease of the lung, related to high blood-pressure. Essentially, the increased pressure causes some pulmonary arteries and veins to work at drastically different rates than others, creating an imbalance that can cause fatigue, shortness of breath, fainting, and a persistent cough.
Does hyperbilirubinemia cause cyanosis?
Hyperbilirubinemia causes jaundice.
