Cyanosis is a blue coloration of the skin and mucous membranes due to the presence of deoxygenated hemoglobin in blood vessels near the skin surface. It occurs when the oxygen saturation of arterial blood falls below 85-90% (1.5g/dl deoxyhemoglobin). Although human blood is always a shade of red (except in rare cases of hemoglobin-related disease), the optical properties of skin distort the dark red color of deoxygenated blood to make it appear bluish.

What doctor discovered cyanosis?
Dr. Ettie Levy first described cyanosis as a symptom in cases of congenital heart disease in a medical journal in 1874. However, Dr. Trousseau is often credited with coining the term "cyanosis" in the early 1800s.

Cyanosis - bluish, purplish coloring of the skin, most often the extremeties, and more seriously, the appendages.
What is the result of inadequate oxygen to the extremities characteristic of bluish appearance called?
This condition is called cyanosis. Cyanosis is caused by insufficient oxygen in the blood, leading to a bluish discoloration of the skin, usually appearing in the extremities or lips. It is often a sign of underlying health issues that affect the circulation or oxygenation of the blood.
What does a low paO2 value mean?
A low paO2 (partial pressure of oxygen in arterial blood) value indicates that the oxygen level in the blood is below normal, which can signify inadequate oxygenation of the tissues. This condition may result from respiratory issues, such as chronic obstructive pulmonary disease (COPD), pneumonia, or pulmonary edema, and can lead to symptoms like shortness of breath, confusion, or cyanosis. It is often used in clinical settings to assess the severity of respiratory failure and guide treatment decisions.
Heavy smokers are often prone to?
Respiratory infections
What is squatting during cyanosis?
Squatting during cyanosis is a compensatory behavior often observed in children with certain congenital heart defects, such as Tetralogy of Fallot. When cyanosis occurs, indicating low oxygen levels in the blood, squatting helps increase systemic vascular resistance, which can improve blood flow to the lungs and enhance oxygenation. This position also reduces the right-to-left shunt of blood, allowing for better oxygenation and alleviating some symptoms of hypoxia.
Is it safe to be in a room with a dehumidifier running?
Yes. In fact they're often used for people with Asthma and other respiratory problems that humidity can have adverse effects on.
A barrel chest is often indicative of what respiratory disease?
emphysema
What is heliotrope cyanosis?
Cyanosis is the discoloration of the skin due to lack of oxygen. When the blood oxygen levels fall the circulatory system constructs vessels going to the skin so that more blood is routed to internal organs. Less blood at the skin surface means that less red light is scattered back and the blue light becomes more prominent. This can be caused by choking on something, or fluid in the lungs (pneumonia) Heliotrope cyanosis is a term coined during the flu pandemic of 1918. A victim would get the flu, and get a secondary infection. His lungs would fill with fluid, preventing him from breathing, and his face would turn blue as he died drowning in his own fluids. The color of the people's faces was so striking they called it "heliotrope cyanosis"
