In people with lighter skin, respiratory failure can lead to a change in the color of the skin. which pigmentation factor is affecting this change?

Answer;

Hemoglobin

Explanation;

In people with lighter skin, respiratory failure can lead to a change in the color of the skin. the pigmentation factor that is affecting this change is hemoglobin.

-As the blood becomes hypoxic, hemoglobin is carrying less oxygen. This deoxygenated state leads to the condition known as cyanosis, which is a bluish cast to the skin and mucous membranes. Peripheral cyanosis is when there is a bluish discoloration to your hands or feet.

Cyanosis is usually caused by low oxygen levels in the red blood cells or problems getting oxygenated blood to your body.

you know that this symptom is misleading and quite often is related to: heart attack

a heart attack is a condition that occurs when the blood flow that transports oxygen to the heart muscle is damaged or cut off completely. the coronary arteries that supply the heart muscle with blood flow can be blocked by the accumulation of plaque. also, when the plaque within the heart artery breaks, it creates blood clot that can also hinder the blood flow. men that are over 45years of age and women that are over 55years of age are at risk of having a heart attack. the symptoms of a heart attack include chest discomfort, chest pain, coughing, and shortness of breath.
