Q: Until recently, my blood pressure stayed around 135/75. About two weeks ago, my blood pressure suddenly shot up to 188/90. My doctor increased the doses of my blood pressure pills. But my systolic pressure is still around 170. Why would my blood pressure have increased so suddenly when I hadn't really changed anything? Is 170 systolic OK given my diastolic pressure is 80? A: One of the mysteries of blood pressure is that it can rise or fall without any obvious changes in your life.
The level of CO concentration is measured using a system called Parts Per Million (PPM). For example, 100 PPM CO means that for every 999,900 molecules of air, there are 100 molecules of CO. CO effects people differently depending on the concentration.
Normal Levels of Carbon Monoxide in a Home. In the U.S., about 170 people die each year from prolonged exposure to carbon monoxide in the home. The levels of carbon monoxide, or CO, in your home will vary if a gas stove is present and properly adjusted, according to the Environmental Protection Agency (EPA). If you own a gas stove, the average CO level in your home will range from 5 to 15 parts per million (ppm). If your gas stove is poorly adjusted, the average CO reading is closer to 30 ppm or higher, which can cause dangerous reactions if the problem remains unresolved.
