For example a typical value for this ratio for a human would be 120/70, where the pressures are in mm Hg (millimeters of mercury, SG = 13.6). What would these pressures be in kPa (kilo Pascals)?: (a) systolic pressure (kPa), (b) diastolic pressure (kPa).arrow_forward
- Systemic blood pressure is defined as the ratio of two pressures—systolic and diastolic—both expressed in millimeters of mercury. Normal blood pressure is about 120mm/80mm which is usually just stated as 120/80.
