RACHEL MARTIN, HOST: Rabbit, rabbit. Some of you may have said that first thing this morning. And for those still slowly rising - get to it, it could bring you good luck all month long. Saying rabbit, rabbit on the first of the month is supposed to be a harbinger of good fortune.
From Wikipedia, the free encyclopedia. The mean arterial pressure (MAP) is a term used in medicine to describe an average blood pressure in an individual. It is defined as the average arterial pressure during a single cardiac cycle.
When the mean arterial pressure is perturbed from the regulated level, the cardiac output and the total peripheral resistance are adjusted to bring the mean arterial pressure back to the specified level. Over seconds to minutes, this regulation is due to the carotid baroreceptor reflex.he posterior tibial artery in the ankle is smaller with a lower compliance. Therefore, you expect a higher pulse pressure. A higher pulse pressure implies a higher systolic pressure, assuming the mean arterial pressure is about the same. This is one reason why the normal ankle/brachial index is 1.1 to 1.3.
