HHNKC is also known as diabetic hyperglycemic hyperosmolar coma (HHOC), hyperosmolar nonketotic coma (HONK), hyperosmolar hyperglycemic state (HHS) or hyperosmolar hyperglycemic nonketotic syndrome (HHNS). In HHNKC, blood sugar levels rise, and your body tries to get rid of the excess sugar by passing it into your urine.
Pressures sores result from the death (necrosis) of tissues due to local deprivation of blood supply, and thus of oxygen (ischemic necrosis). This is why tissue compression is the first clinical sign of pressure sores; it blocks the small blood vessels supplying tissues.
Pulmonary hypertension (or PHT) is high blood pressure that occurs in the arteries in the lungs. It is a different measurement altogether from systemic blood pressure. It reflects the pressure the heart must exert to pump blood from the heart through the arteries of the lungs. The blood pressure measured on your arm isn't directly measuring anything related to the blood flow between your heart and lungs.
