| high-frequency jet ventilation | Respiratory support system used primarily with rates of about 100 to 200/min with volumes of from about one to three times predicted anatomic dead space. Used to treat respiratory failure and maintain ventilation under severe circumstances. (12 Dec 1998) |

| jet ejector pump | A suction pump in which fluid under high pressure is forced through a nozzle into an abruptly larger tube where a high velocity jet, at a low pressure in accordance with Bernoulli's law, entrains gas or liquid from a side tube opening just beyond the end of the nozzle to create suction; e.g., the pump by which steam is used to evacuate an autoclave, a water aspirator. (05 Mar 2000) |
| jet injection | Hypodermic injection of drugs by a jet injector. (05 Mar 2000) |
| jet injector | An injector that uses high pressure to force a liquid through a small orifice at a velocity sufficient to penetrate skin or mucous membrane without the use of a needle. (05 Mar 2000) |
| jet lag | An imbalance of the normal circadian rhythm resulting from subsonic or supersonic travel through a varied number of time zones and leading to fatigue, irritability, and various functional disturbances. (05 Mar 2000) |
| jet nebuliser | An atomiser that uses an air or gas stream to change a liquid into small particles. (05 Mar 2000) |
| maternal exposure | Exposure of the female parent, human or animal, to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals that may affect offspring. It includes pre-conception maternal exposure. (12 Dec 1998) |
| maximum permissible exposure level | The highest level of exposure to a substance, usually noxious, in the environment or during diagnostic and therapeutic procedures, that a body can tolerate without injury. (12 Dec 1998) |
| paternal exposure | Exposure of the male parent, human or animal, to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals that may affect offspring. (12 Dec 1998) |
| permissible exposure limit | An occupational health standard to safeguard workers against dangerous contaminants in the workplace. (05 Mar 2000) |
| prenatal exposure delayed effects | Delayed effects on offspring of maternal or foetal prenatal exposure to drugs, radiation and other physical agents, manipulation, nutrition, stress, etc. (12 Dec 1998) |
| short-term exposure limit | The maximum concentration of a chemical to which workers may be exposed continuously for up to 15 minutes without danger to health or work efficiency and safety. (05 Mar 2000) |
| dental pulp exposure | The result of pathological changes in the hard tissue of a tooth caused by carious lesions, mechanical factors, or trauma, which render the pulp susceptible to bacterial invasion from the external environment. (12 Dec 1998) |
