Rate, mortality
The number of maternal deaths related to childbearing divided by the number of live births (or by the number of live births + fetal deaths) in that year.
The word “mortality” came from the Latin “mors” (death). Mortality is distinct from morbidity (illness). A condition such as tuberculosis can cause morbidity and mortality (disease and death). The Morbidity and Mortality Weekly Report (MMWR) is an important weekly publication by the US Centers for Disease Control and Prevention (the CDC).

- Rate, pulse
The pulse rate is most often taken at the wrist. It measures the number of pulsations in the radial artery each minute. This most often reflects heart rate.
- 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.
- Rattlesnake bite
A poisonous bite by a member of the pit viper family. All rattlesnakes are venomous and secrete poisonous venom. Rattlesnakes are the main cause of death from snake bites in the United States. The emergency treatment of rattlesnake bites is essential. With proper care, rattlesnake bites are rarely fatal. Do not use a tourniquet or […]
- Rate, sedimentation
A blood test that detects and monitors inflammation in the body. It measures the rate at which red blood cells (RBCs) in a test tube separate from blood serum over time, becoming sediment in the bottom of the test tube. The sedimentation rate increases with more inflammation. Also called the erythrocyte sedimentation rate. Abbreviated as […]
