| rate, neonatal mortality | The number of children dying under 28 days of age divided by the number of live births that year. The neonatal mortality rate in the united states, which was 8.4 per 1,000 live births in 1980, declined to 5.8 per 1,000 live births in 1990. (12 Dec 1998) |

| rate, pulse | The pulse rate is most often taken at the wrist. It measures the number of pulsations in the radial artery each minute. (12 Dec 1998) |
| rate, respiratory | The number of breaths per minute (or, more formally, the number of movements indicative of inspiration and expiration per unit time). In practice, the respiratory rate is usually determined by counting the number of times the chest rises (or falls) per minute. By whatever means, the aim is to determine if the respirations are normal, abnormally fast (tachypnea), abnormally slow (technically termed bradypnea), or nonexistent (apnea). (12 Dec 1998) |
| rate schedule | A price list showing how the electric bill of a particular type of customer will be calculated by an electric utility company. (05 Dec 1998) |
| rate, sed | A sedimentation rate, or sed rate , is a blood test that detects and is used to monitor inflammation activity. It is measured by recording the rate at which red blood cells (rbcs) sediment in a tube over time. It increases (the rbcs sediment faster) with more inflammation. (12 Dec 1998) |

| rate setting and review | A method of examining and setting levels of payments. (12 Dec 1998) |
| general fertility rate | A refined measure of fertility in a population; the numerator is the number of live births in a year, the denominator is the number of females of child-bearing age, usually defined as ages 15-44 (but increasingly recognised as extending to age 49). (05 Mar 2000) |
| recurrence rate | In genetic counseling, the risk that a future offspring will be affected given some specific set of relatives of whom at least one is already affected. (05 Mar 2000) |
| case fatality rate | The proportion of individuals contracting a disease that die of that disease. (05 Mar 2000) |
| maternal death rate | The number of maternal deaths that occur as the direct result of the reproductive process per 100,000 live births. See: rate. See: maternal death. (05 Mar 2000) |
| maternal mortality rate | The number of maternal deaths related to childbearing divided by the number of live births (or by the number of live births + foetal deaths) in that year. The maternal mortality rate in the united states in 1993 (and 1994) was 0.1 per 1,000 live births, or 1 mother dying per 10,000 live births. (12 Dec 1998) |
| glomerular filtration rate | <nephrology> Measure of the kidneys' ability to filter and remove waste products. (09 Oct 1997) |
| repetition rate | The number of pulses per minute, describing an energy outpute.g., ultrasound pulses in echocardiography rather than vascular pulses. (05 Mar 2000) |
| volume loading rate | The rate of raw materials put into a fermenter or aerobic digester, expressed in terms of material weight per unit volume per unit time. (09 Oct 1997) |
