Cystitis â Inflammation of the bladder, usually caused by bacterial infection. Reflux â The backward flow of a fluid in the body. Pyelonephritis is often associated with the reflux of urine from the bladder to the upper urinary tract.
What does the diastolic blood pressure number mean? The diastolic blood pressure number or the bottom number indicates the pressure in the arteries when the heart rests between beats. A normal diastolic blood pressure number is 80 or less. A diastolic blood pressure between 80 and 89 is normal but higher than ideal. A diastolic blood pressure number of 90 or higher, on repeated measurements, is considered to be hypertension or high blood pressure.
Systemic pulse pressure = Psystolic-Pdiastolic. The difference between systolic (the upper number) and diastolic (the lower number) pressures is known as the pulse pressure : Systemic pulse pressure = P systolic-P diastolic. For a typical blood pressure reading of 120/80 mmHg the pulse pressure is therefore 40 mmHg.
