My son Cam is just about 6 mths old, and lately myself and others have been noticing his hands and feet turn blue ( cyanosis) and sometimes around his mouth. The majority of the time, it s while he s having a bottle, or just waking up. His hands and feet turn blue at bath time also, although I always warm up the house extra, and make sure his water his warm, even adding warm water as I go. When he was just two- days- old, I noticed his lips and around his nose were blue, so I called the nurse down to my room, and she told me he just needed to burp. After he did, he was still blue so she took him down and checked his vitals, and at that time all was fine, must have been gas she said. I have an appt made with his doctor for the 19th and but should I insist he be seen before then Also he was tested for Cystic Fibrosis when he was 1 mth due to a prolapsed rectum. He had the sweat chloride test done, and the tech who administered it said she thought she got enough sweat , when the doctor called with the results, he said he was in the clear based on the amount of the sample , but seemed hesitant, all at the same time. Do you know if it s possible for a sweat chloride test to be wrong? Also no matter where he s touched, regardless of pressure, his skin turn blotchy red.

Hi, I understand your concerns, but blue colored skin means that there is not enough oxygenated blood supply reaching this area of skin. This could be due to a problem in the blood vessels or due to a problem in the heart that is unable to pump enough blood to different parts of the body. This needs a thorough examination by echocardiogram to exclude any chaotic heart disease. I recommend also to repeat the test for cystic fibrosis in another laboratory to make sure of the result. Hope I have answered your query. Let me know if I can assist you further.
