Incubators: Insulated enclosures in which temperature, humidity, and other environmental conditions can be regulated at levels optimal for growth, hatching, reproduction, or metabolic reactions.Incubators, Infant: Electrically powered devices that are intended to assist in the maintenance of the thermal balance of infants, principally by controlling the air temperature and humidity in an enclosure. (from UMDNS, 1999)Heating: The application of heat to raise the temperature of the environment, ambient or local, or the systems for accomplishing this effect. It is distinguished from HEAT, the physical property and principle of physics.Infant Care: Care of infants in the home or institution.Embryo Culture Techniques: The technique of maintaining or growing mammalian EMBRYOS in vitro. This method offers an opportunity to observe EMBRYONIC DEVELOPMENT; METABOLISM; and susceptibility to TERATOGENS.Humidity: A measure of the amount of WATER VAPOR in the air.Environment, Controlled: A state in which the environs of hospitals, laboratories, domestic and animal housing, work places, spacecraft, and other surroundings are under technological control with regard to air conditioning, heating, lighting, humidity, ventilation, and other ambient features. The concept includes control of atmospheric composition. (From Jane's Aerospace Dictionary, 3d ed)Water Loss, Insensible: Loss of water by diffusion through the skin and by evaporation from the respiratory tract.Intensive Care Units, Neonatal: Hospital units providing continuing surveillance and care to acutely ill newborn infants.Equipment Design: Methods of creating machines and devices.Infant, Premature: A human infant born before 37 weeks of GESTATION.Thermometers: Measuring instruments for determining the temperature of matter. Most thermometers used in the field of medicine are designed for measuring body temperature or for use in the clinical laboratory. (From UMDNS, 1999)Neonatal Nursing: The nursing specialty that deals with the care of newborn infants during the first four weeks after birth.Body Temperature: The measure of the level of heat of a human or animal.Infant, Newborn: An infant during the first month after birth.Suppuration: A pathologic process consisting in the formation of pus.Equipment and Supplies: Expendable and nonexpendable equipment, supplies, apparatus, and instruments that are used in diagnostic, surgical, therapeutic, scientific, and experimental procedures.Bacteriological Techniques: Techniques used in studying bacteria.Infant, Newborn, Diseases: Diseases of newborn infants present at birth (congenital) or developing within the first month of birth. It does not include hereditary diseases not manifesting at birth or within the first 30 days of life nor does it include inborn errors of metabolism. Both HEREDITARY DISEASES and METABOLISM, INBORN ERRORS are available as general concepts.Gases: The vapor state of matter; nonelastic fluids in which the molecules are in free movement and their mean positions far apart. Gases tend to expand indefinitely, to diffuse and mix readily with other gases, to have definite relations of volume, temperature, and pressure, and to condense or liquefy at low temperatures or under sufficient pressure. (Grant & Hackh's Chemical Dictionary, 5th ed)Hypothermia: Lower than normal body temperature, especially in warm-blooded animals.Temperature: The property of objects that determines the direction of heat flow when they are placed in direct thermal contact. The temperature is the energy of microscopic motions (vibrational and translational) of the particles of atoms.Electric Power Supplies: Devices that control the supply of electric current for running electrical equipment.
