Fahrenheit: Thermometer scale in which the freezing point of water is 32°F and the boiling point of water 212°F.
The Fahrenheit scale is still obstinately in use in the US. This anachronism requires conversion from Centigrade (°C) to Fahrenheit (°F), and vice versa.
One degree °C = (5/9)(°F – 32).
One degree °F = (9/5)(°C) + 32.
Named for Gabriel Fahrenheit, a German-Dutch physicist, who devised the scale in 1724. 0°F was the lowest temperature that Fahrenheit could obtain using a mixture of ice and salt.
- Failure to thrive (FTT)
Failure to thrive (FTT): Refers to a child whose physical growth is significantly less than that of peers. There is no official consensus on what constitutes failure to thrive (FTT). It usually refers to a child whose growth is below the 3rd or 5th percentiles for their age or whose growth has fallen off precipitously […]
- Failure, adrenal
Failure, adrenal: A condition in which the adrenal glands do not produce enough of the adrenal hormones that control important functions such as blood pressure. The adrenal glands sit on top of the kidneys. The adrenal is made up of an outer layer (the cortex) and an inner portion (the medulla). The adrenal glands produce […]
- Failure, heart
Failure, heart: Inability of the heart to keep up with the demands on it and, specifically, failure of the heart to pump blood with normal efficiency. When this occurs, the heart is unable to provide adequate blood flow to other organs such as the brain, liver and kidneys. Heart failure may be due to failure […]
- Fainting (syncope)
Heart conditions that can cause syncope or fainting due to temporary loss of consciousness include: Abnormal heart rhythms (heart beating too fast or too slow). Abnormalities of the heart valves (aortic stenosis or pulmonic valve stenosis). High blood pressure in the arteries supplying the lungs (pulmonary artery hypertension). Tears in the aorta (aortic dissection). Widespread […]
- Falciparum malaria
Falciparum malaria: The most dangerous type of malaria, which is caused by the parasite Plasmodium falciparum. Falciparum malaria is associated with high levels of parasites in the blood and has the highest death rate and rate of complications of all types of malaria. Red blood cells that are infected with the parasite tend to sludge […]
