Hyperglycemic hyperosmolar nonketotic coma  (HHNKC) is an extremely serious complication of type 2 diabetes, most often occurring in those who are non-insulin dependent. HHNKC can happen to people with either type 1 or type 2 diabetes that is not being controlled properly, but it occurs more often in people with type 2.
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.
Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled gage pressure) is the pressure relative to the local atmospheric or ambient pressure.he SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m 2 or kgÂ·m â1 Â·s â2). This name for the unit was added in 1971; before that, pressure in SI was expressed simply in newtons per square metre.
