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.
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.

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.
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).
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.
Pneumonia can cause cyanosis due to impaired gas exchange in the lungs, leading to decreased oxygen levels in the blood. When the alveoli become inflamed and filled with fluid or pus, oxygen cannot effectively diffuse into the bloodstream, resulting in hypoxemia. This lack of adequate oxygenation causes a bluish discoloration of the skin and mucous membranes, known as cyanosis. In severe cases, it can indicate a critical need for medical intervention.

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.
Cyanosis itself is a symptom and not a direct cause of death. However, cyanosis may indicate that there is a lack of oxygen in the blood, which could be a sign of a serious underlying medical condition that, if left untreated, could lead to death. It is important to seek medical attention if you are experiencing cyanosis.
yes cyanosis is usually curable but the cause of cyanosis may not be (e.g. active dying).
Decreased blood supply in the muscle can cause anoxia then paralysis.
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.
High blood pressure (hypertension) can contribute to the development of various cardiovascular conditions, including aneurysms in the aorta, but it is not a direct cause of pulmonary aneurysms. Pulmonary aneurysms, which occur in the pulmonary arteries, are more commonly associated with conditions such as pulmonary hypertension, infections, or congenital heart defects. While hypertension can exacerbate existing vascular problems, it is not the primary cause of pulmonary aneurysms.

The bluish tint that skin acquires from cold or decreased oxygen levels in the tissues is known as cyanosis. It occurs when there is insufficient oxygen in the blood, leading to a bluish appearance, particularly in areas with thin skin like the lips and fingertips. Conditions such as respiratory illnesses, heart defects, or exposure to extreme cold can lead to cyanosis by impairing oxygen delivery to tissues. It's a clinical sign that requires prompt evaluation to determine the underlying cause.
Yes, when severe.
