Cyanosis

• Cyanosis is not a disease and it is a condition.
  The skin color of the lips and the fingertips
  becomes light bluish in color at the time of
  cyanosis. This condition is an indication of the
  low oxygen levels in the blood.Blood takes a
  bluish glow if it does not have adequate levels
  of oxygen. Blood under normal condition is known
  to be bright red in color owing to the protein
  molecules called hemes.Though when the oxygen
  levels in the RBC lowers down, it can cause
  bluish coloration on the limbs and lips. This
  condition is known as cyanosis. Cyanosis is a
  symptom indicating the body cannot deliver
  adequate amount of oxygenated blood.Very cold
  weather can also narrow the blood vessels
  reducing the oxygen supply causing bluish glow
  temporarily. But that condition is not cyanosis
  and it can be resolved by gentle massaging of
  affected areas.

Causes of Cyanosis

• Less amount of oxygen level in the blood is the
  major cause for cyanosis. Some diseases such as
  congestive heart failure, sepsis shock, narrowing
  of blood vessels, pneumonia, and carbon monoxide
  poisoning, peripheral vascular disease, exposure
  to cold temperature, pulmonary embolism, COPD and
  high respiratory tract infections can cause
  cyanosis.Cardiac shunt, lung diseases and
  infection, polycythemia Vera, and Beta blocking
  drugs can also trigger cyanosis in adults.

Diagnosis of Cyanosis

• The doctor would first complete physical
  examination based on the symptoms of blue
  discoloration of nails and lips. The doctor would
  measure the carbon dioxide levels and oxygen
  levels in the blood using noninvasive pulse
  oximeter. ECG, Chest X-ray or echo test and
  hemoglobin levels and arterial blood gas test may
  also be done.

Symptoms of Cyanosis

• Blue coloration of the lips and fingertips are
  the major identifications of cyanosis. However
  there can be some accompanied symptoms if there
  is underlying cause.Patients who are having
  lungs and heart diseases can develop cyanosis
  gradually. Like people who are taking drugs that
  contain nitrates and dapsone can develop cyanosis
  over years.Different symptoms related to
  cyanosis include rapid heartbeat, palpitation,
  chest pain (ranging from dull to severe chest
  tightening), dyspnea and blue discoloration of
  the skin on the extremities.

Treatment of Cyanosis

• Emergency treatment is to be provided if the
  patient condition is unstable. Oxygen therapy is
  started very early to restore the oxygen levels
  in blood. Treatment for cyanosis involves finding
  the underlying factors or disease causing it.
  Lungs and heart problems should be addressed and
  promptly treated.
