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 HERS Rating uses systematic approach to measure the energy efficiency of a home. The test produces a number which will show how much better or worse the home will perform when compared to the âstandard home.â With an existing home, this rating creates a simple way to understand the homeâs energy efficiency.
