RN stands for registered nurse. RNs are very different from LPNs. The amount of schooling and education is longer for an RN. RNs usually go through two to four year programs at community colleges and universities. They graduate with a BSN (Bachelor's of Science In Nursing) or an ADN (Associate's Degree In Nursing).
It is important to understand what causes it in your home so you can protect your family from the dangers of carbon monoxide poisoning. Never unplug or remove the battery to silence a CO detector or CO alarm. You may go back to sleep and suffer the deadly consequences of carbon monoxide poisoning. At the very least, ventilate the area and change the detector's battery. Always assume the worst for your own safety.
Carbon monoxide poisoning is caused by inhaling combustion fumes. When too much carbon monoxide is in the air you're breathing, your body replaces the oxygen in your red blood cells with carbon monoxide. This prevents oxygen from reaching your tissues and organs.
