10 Symptoms of Croup
Reviewed: Dr. Gromatzky
Symptom #10: Blue/Gray Skin
Our blood is red in color because of the presence of iron. This iron helps to carry oxygen around the body because oxygen binds tightly to iron naturally. If there is a lack of oxygen then the blood will begin to lose its deep red color. This can be noticeable externally as the patient’s skin changes color.
This is often most noticeable around the lips where the blood vessels are particularly close to the surface. This can result in blue/gray lips and also around the nose and in the fingernails. This is a clear sign that your little one is not getting enough oxygen and this should be treated as a medical emergency.
