| Frank-Starling curve | A graph in which cardiac output or stroke volume is plotted against mean atrial or ventricular end-diastolic pressure; with increasing venous return and atrial pressure the output proportionately increases until further increments overload the heart and the output falls. Synonym: Frank-Starling curve. (05 Mar 2000) |

| frequency curve | A systematic grouping of data into classes or categories according to the frequency of occurrence of each successive value or ranges of such values, resulting in a graph of a frequency distribution. Synonym: frequency curve. (05 Mar 2000) |
| Friedman curve | A graph on which hours of labour are plotted against cervical dilation in centimeters. (05 Mar 2000) |
| logistic curve | An S-shaped curve which depicts the growth of a population in an area of fixed limits. (05 Mar 2000) |
| abortion rate | The number of abortions per 1000 terminated pregnancies during a given period of time. (05 Mar 2000) |
| age-specific rate | A rate for a specified age group, in which the numerator and denominator refer to the same age group. (05 Mar 2000) |
| attack rate | A cumulative incidence rate used for particular groups observed for limited periods under special circumstances, such as during an epidemic. (05 Mar 2000) |
| average flow rate | <physiology> The flow rate determined by dividing the total volume passed in a time period divided by the time period, usually quoted in mls per minute. (05 Mar 2000) |

| basal metabolic rate | <biochemistry, biology> The metabolic rate as measured under basal conditions: 12 hours after eating, after a restful sleep, no exercise or activity preceding test, elimination of emotional excitement and occurring in a comfortable temperature. Acronym: BMR (15 Nov 1997) |
| baseline foetal heart rate | <paediatrics> The average heart rate for a particular foetus during the diastolic phase of uterine contractions. (05 Mar 2000) |
| baseline variability of foetal heart rate | The beat-to-beat changes in foetal heart rate as recorded on a graph. (05 Mar 2000) |
| basic reproductive rate, ratio | <epidemiology> See Reproductive Ratio. (05 Dec 1998) |
| birth rate | The birth rate is usually given as the number of live births divided by the average population (or the population at midyear). This is termed the crude birth rate. In 1995, for example, the crude birth rate per 1,000 population was 14 in the United States, 16.9 in Australia, etc. (12 Dec 1998) |
| breathing rate | <chest medicine, clinical sign> Also referred to as the respiratory rate. Measured as the number of breaths taken every minute. Normal resting adult respiratory rates are from 16-20 breaths per minute. The normal 1 year old infant can have a respiratory rate of 30 breaths per minute. Count the breaths taken in 30 seconds observing the rise and fall of the chest and then multiply this number by 2. (27 Sep 1997) |
