Home pregnancy tests are a qualitative test and measure whether or not hCG -- the pregnancy hormone human chorionic gonadotropin -- is present in your urine, explains Stephen Rechner, M.D., the Division Chief of General Obstetrics and Gynecology at Spectrum Health in Grand Rapids.
After breathing in carbon monoxide, it enters your bloodstream and mixes with haemoglobin (the part of red blood cells that carry oxygen around your body), to form carboxyhaemoglobin. When this happens, the blood is no longer able to carry oxygen, and this lack of oxygen causes the bodyâs cells and tissue to die.
In spite of asphyxiation, cyanosis (turning blue) does not occur; the skin is pink or pale and the lips bright red. Indications of carbon monoxide poisoning include headache, weakness, dizziness, nausea, fainting, and, in severe cases, coma, weak pulse, and respiratory failure. Death from exposure is thought to originate from reduced blood supply to the heart muscle (myocardial ischemia) and irregular heartbeat (arrhythmia).
