CRAO is considered a stroke of the eye. Studies show that about two-thirds of patients have underlying high blood pressure and one-fourth of patients will have significant carotid artery disease (plaque with narrowing of the artery lining), cardiac valvular disease or diabetes.
Electrical pressure is measured in volts, or voltage. All electrical devices are rated for specific voltages. Most devices and small appliances in a home are rated for 120 volts, while high-voltage appliances, such as electric dryers, ranges, and many baseboard heaters, are rated for 240 volts.
A watt is used to measure power, and power is simply the rate at which you use energy. So your q â¦ uestion is just like asking, 'How many miles per hour does an average car do over a month'! What you should be asking is how many kilowatt hours of energy does an average house use over a month.
