Your immune system then reacts by causing joint inflammation.
One theory is that once your immune system has dealt with the infection, fragments of bacteria travel through your bloodstream and collect in the lining of your joints. It is not yet known exactly why infections trigger reactive arthritis. The infection itself may have been so mild you barely noticed it. The pain, swelling and extreme tiredness of reactive arthritis come after the initial infection. However, some people find it lasts longer and can have random flare-ups years after they first get it. Unlike other types of inflammatory arthritis, for many people reactive arthritis lasts a relatively short amount of time - usually around three months to a year. Reactive arthritis is a type of inflammatory arthritis. It’s sometimes called Reiter syndrome and can affect people of any age, including children. The most common joints to be affected are the knees and ankles. It can affect your joints after you’ve had an infection somewhere else in your body, such as a tummy bug, diarrhoea (die-a-ree-ah), or a throat infection. 2018 12(3):203-215.Reactive arthritis causes you to have extremely painful, swollen joints and can make you feel very tired.

ARDs (Acute Respiratory Distress Syndrome) due to impaired gaseous exchange.COPD - in both chronic bronchitis and emphysema.Right to left shunt in congenital heart disease.Embolism and ventilation perfusion mismatch.Impaired gas exchange secondary to pneumonia.Central Cyanosis Ĭentral Cyanosis (mouth, lips and tongue) indicates a gaseous exchange problem, although it is an unreliable measure for hypoxaemia. Low cardiac output, venous stasis (the pooling of blood in the veins), or exposure to extreme cold causing vasoconstrictions. Peripheral Cyanosis (fingers, toes and ears) occurs as a result of increased oxygen extraction by the peripheral tissue in the capillary bed. wearing clothing or jewellery that's too tight.a blood clot that stops the blood supply to or from a limb.beta blockers, a medicine used to treat high blood pressure.Raynaud's Phenomenon, which affects your fingers and toes.The blue colouration is due to the unsaturated haemoglobin in the blood. Cyanosis can mean that there is not enough oxygen in the arterial blood (<80-85%), or poor blood circulation. In fact,the parts of the body most commonly affected are:įor dark skin, cyanosis may be easier to see:Ĭyanosis can be classified as central, peripheral, and differential.Ĭyanosis is a pathologic sign taht does not represent a disease by itself. Presentation Ĭyanosis can be best appreciated in areas with rich superficial vasculature and thin overlying dermis.
