Central Cyanosis is very often caused by a circulatory or ventilatory issue. This in turn could lead to poor blood oxygenation in the lungs. Acute Cyanosis is a condition that could result from asphyxiation or choking.
It is amongst the sure signs of respiration being blocked. Peripheral Cyanosis is a bluish tint observed in the fingers or toes, caused by suboptimal or restricted blood circulation. Blood reaching the fingers and toes is not oxygen-rich enough; when observed through the skin, it gives off the appearance of a blue colour. All the conditions that cause Central Cyanosis, can also cause Peripheral symptoms to appear.
Peripheral Cyanosis can sometimes be noticed even in the absence of heart or lung failures. Small blood vessels could be constricted and may be treated by boosting normal oxygenation levels of the blood.
This condition is normally observed especially in patients with a patent ductus arteriosus. Patients with a large ductus develop progressive pulmonary vascular disease, and pressure overload of the right ventricle occurs.
As soon as pulmonary pressure exceeds aortic pressure, shunt reversal right-to-left shunt occurs. Upper extremity of the body remains pink in colour because the brachiocephalic trunk, left common carotid trunk, and the left subclavian trunk is given off proximal to the PDA. Age-related and the nature of Cyanosis onset:. Previous history: Cyanosis may also be caused by any lung disease of sufficient intensity.
Drug history: there are a set of drugs that may result in methemoglobinemia e. Features that are localised may indicate aetiology of Peripheral Cyanosis. These could cover oedema in venous insufficiency or absence of Peripheral pulses and an ischaemic condition in arterial occlusion.
Bluish skin is usually a sign of something serious. If normal colour does not return when your skin is rubbed or warmed, it is important to get medical attention right away to determine the cause.
The physical examination performed by your doctor will include listening to your heart and lungs. You may also have to undergo a series of other clinical tests. Apart from the clinical assessment of hypoxemia, the diagnosis of Cyanosis may also include the following investigations:.
The treatment involves identifying and correcting the underlying cause in order to restore the oxygenated blood flow to the affected parts of the body. Receiving proper treatment in a timely manner will improve the outcome and limit any complications.
It is important that any medication in Cyanosis Treatment should always be under the prescription and guidance of a registered medical practitioner. You may also need to avoid certain medications that constrict blood vessels as a side effect.
These include types of:. Serious medical situations, such as heart or pulmonary related conditions, should be treated in a hospital as an emergency. These include avoiding caffeine and nicotine, both of which can cause your blood vessels to constrict. What is Cyanosis? Cyanosis is generally a medical condition in which there's a blue tint to the skin, indicating the body is not receiving enough oxygen-rich blood.
What is cyanosis a symptom of? Cyanosis occurs when oxygen-depleted deoxygenated blood, which is bluish rather than red, circulates through the skin. Cyanosis can be caused by many types of severe lung or heart disease that cause levels of oxygen in the blood to be low. What are the principal reasons for cyanosis? The three primary reasons of cyanosis include - Decreased pumping of blood by the heart or reduced cardiac output often seen in heart failure or circulatory shock; Diseases of circulation like thrombosis or embolism, and constriction of blood vessels of the limbs, fingers, and toes due to exposure to cold, spasm of the smaller skin capillaries or arteries called acrocyanosis.
The other leading causes of Cyanosis in both adults and newborns include:. On the other hand, patients with chronic obstructive lung disease or COPD often develop cyanosis gradually over many years.
To determine if the cyanosis is mild or severe can be done by analyzing the following:. In general, cyanosis is known to worsen with activity, and only proper resting can one bring it down. Dark skin complexion and the presence of anemia can often make it hard for the parents and doctors alike to recognize signs of mild cyanosis. In situations like these, a purple or blue tongue is the sign of a medical emergency. Seeking emergency medical aid if the tongue is discoloured, appears suddenly or is even seen to be accompanied by:.
Skip to main content. Narayana Health » Cyanosis. NH cares Cyanosis Blue colouration of lips, feet, body :. Diagnosis and treatment. Types of Cyanosis. Central Cyanosis Central Cyanosis is a blue discoloration seen on the tongue and lips, and is due to lower levels of oxygen in the Central arterial blood; caused by cardiac or respiratory disorders.
Peripheral Cyanosis Peripheral Cyanosis is a blue or purple skin discoloration of the extremities, viz. Differential Cyanosis Differential or Mixed Cyanosis is diagnosed when the bluish discoloration is present in certain parts of the body and absent in others.
Causes of Cyanosis. Central Cyanosis Causes Central Cyanosis is very often caused by a circulatory or ventilatory issue. Central Cyanosis may be caused by the following issues: 1. Central nervous system related conditions impairing normal ventilation : Intracranial haemorrhage Drug overdose e.
Respiratory system related conditions: Pneumonia Bronchiolitis Bronchospasm e. Cardiovascular disease related conditions: Congenital heart disease Failure of the heart Valvular heart condition Myocardial infarction condition 4. Blood-related conditions: Methemoglobinemia Polycythaemia Congenital Cyanosis 5. Other conditions: High altitude may trigger off Cyanosis, which may be observed when ascending to altitudes over mts Hypothermia Obstructive sleep apnea Peripheral Cyanosis Causes Peripheral Cyanosis is a bluish tint observed in the fingers or toes, caused by suboptimal or restricted blood circulation.
Peripheral Cyanosis could sometimes occur due to the following: All the common causes of Central Cyanosis Reduced cardiac output e. Peripheral vascular disease, Raynaud phenomenon Venous obstruction e.
Symptoms of Cyanosis. Age-related and the nature of Cyanosis onset: Cyanosis caused by congenital heart disease, which in turn causes anatomical right-to-left shunts, that may have been prevalent from birth or the early years of life.
Acute onset ofCyanosis, which could be caused by conditions like pulmonary emboli, cardiac failure, pneumonia or asthma. People suffering from COPD Chronic Obstructive Pulmonary Disease may develop Cyanosis over time and an associated condition called polycythaemia may exacerbate the intensity of Cyanosis.
Associated symptoms: Pain in the chest : Cyanosis that is associated with pleuritic chest pains could be caused by pulmonary embolism or pneumonia. Pulmonary oedema could cause dull, painful chest tightness. Dyspnoea: this is a condition that may suddenly occur in conjunction with pulmonary emboli, pulmonary oedema or asthma.
Gasping for or shortness of breathing difficulties Fever Headache Profuse sweating profusely Pain or numbness in the arms, legs, hands, fingers, or toes Paling or whitening of the arms, legs, hands, fingers, or toes Dizziness or fainting. Temperature: conditions like pneumonia and pulmonary emboli that could be with pyrexia. The patient will also exhibit symptoms like: Central Cyanosis - this condition produces a bluish discolouration, specially noticed on the mucous membranes of the lips, tongue, fingers and toes.
Peripheral Cyanosis - this condition affects the fingers, toes and skin surrounding the lips, is not noticed around mucous membranes.
A combination of clubbing and Cyanosis is frequent observed in congenital heart disease; it may be prevalent in pulmonary diseases, like lung abscess, bronchiectasis, cystic fibrosis; as also in pulmonary arteriovenous shunts. Pressure in the jugular venous system increases with congestive cardiac failure. After a respiratory examination: Poor chest expansion is a condition that is noticed in patients with chronic bronchitis, and asthma.
Reduced chest expansion may be noticed with conditions like lobar pneumonia. Dullness to percussion is sometimes noticed in an area of consolidation.
Crepitation that is localised may sometimes be heard in conditions like lobar pneumonia. Crepitation is often more likely in conditions like bronchopneumonia and pulmonary oedema. Entry of air may be low with conditions like COPD or asthma.
Bronchial breathing may be affected and wheezing sounds may sometimes be heard, in conditions like asthma. Abnormal heart sounds that are sometimes heard, may suggest origins in the cardiac area.
Diagnosis of Cyanosis. Apart from the clinical assessment of hypoxemia, the diagnosis of Cyanosis may also include the following investigations: Arterial Blood Gas test: measures the acidity and levels of carbon dioxide and oxygen in your blood. Complete Blood Count: Haemoglobin levels are increased with the prevalence of chronic Cyanosis. The white cell count increases in conditions like pneumonia and pulmonary embolism.
ECG: Taken to completely rule out the prevalence of cardiac abnormalities. Chest X-ray: the is taken to rule out conditions like pneumonia, pulmonary infarction and cardiac failure. Ventilation-perfusion scan or Pulmonary Angiography is taken to rule out pulmonary causes Echocardiography will serve to look for the presence of any cardiac defects.
The oxygen-depleted blood then is pumped out to the body, to circulate through the skin and other tissues.
The amount of oxygen in the blood can be estimated by pulse oximetry Arterial Blood Gas ABG Analysis and Pulse Oximetry Both arterial blood gas testing and pulse oximetry measure the amount of oxygen in the blood, which helps determine how well the lungs are functioning.
Arterial blood gas tests are invasive Chest x-rays, echocardiography Echocardiography and Other Ultrasound Procedures Ultrasonography uses high-frequency ultrasound waves bounced off internal structures to produce a moving image. It uses no x-rays. Ultrasonography of the heart echocardiography is one of Pulmonary function tests are better at detecting the general type and severity The lungs take oxygen from the air and transfer it to the bloodstream see Exchanging Oxygen and Carbon Dioxide.
Oxygen is needed Many malformations that cause shunts can be treated with surgery or other procedures. Merck and Co. From developing new therapies that treat and prevent disease to helping people in need, we are committed to improving health and well-being around the world.
