| prenatal | <obstetrics> Existing or occurring before birth, with reference to the foetus. Origin: L. Natalis = natal (18 Nov 1997) |
|---|---|
| prenatal care | Care provided the pregnant woman in order to prevent complications, and decrease the incidence of maternal and prenatal mortality. (12 Dec 1998) |
| prenatal diagnosis | Determination of the nature of a pathological condition or disease in the postimplantation embryo, foetus, or pregnant female before birth. (12 Dec 1998) |
| 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) |
| prenatal life | That interval of life between conception and birth; in humans, usually divided into embryonic and foetal periods. (05 Mar 2000) |
| prenatal screening | Screening for the detection of foetal disease, usually by ultrasound examination or by testing amniotic fluid obtained by amniocentesis. Other screening techniques include testing maternal serum and placental biopsy. (05 Mar 2000) |
| ultrasonography, prenatal | The visualization of tissues during pregnancy through recording of the echoes of ultrasonic waves directed into the body. The procedure may be applied with reference to the mother or the foetus and with reference to organs or the detection of maternal or foetal disease. (12 Dec 1998) |
| abdominal respiration | Breathing effected mainly by the action of the diaphragm. (05 Mar 2000) |
| aerobic respiration | A form of respiration in which molecular oxygen is consumed and carbon dioxide and water are produced. (05 Mar 2000) |
| amphoric respiration | A sound like that made by blowing across the mouth of a bottle, heard on auscultation in some cases in which a large pulmonary cavity exists, or occasionally in pneumothorax. (05 Mar 2000) |
| anaerobic respiration | Respiration under anaerobic conditions. The terminal electron acceptor, instead of oxygen in the case of regular respiration, can be: carbon dioxide, Fe2+, fumarate, nitrate, nitrite, nitrous oxide, sulphur, sulphate, etc. Note that anaerobic respiration still uses the electron transport chain to dump the electron while fermentation does not. (09 Oct 1997) |
| artificial respiration | Application of mechanically or manually generated pressures, usually positive, to gas(es) in or about the airway as a means of producing gas exchange between the lungs and surrounding atmosphere. Synonym: artificial respiration. (05 Mar 2000) |
| assisted respiration | Application of mechanically or manually generated positive pressure to gas(es) in or about the airway during inhalation as a means of augmenting movement of gases into the lungs. Synonym: assisted respiration. (05 Mar 2000) |
| Biot's respiration | Completely irregular breathing pattern, with continually variable rate and depth of breathing; results from lesions in the respiratory centres in the brainstem, extending from the dorsomedial medulla caudally to the obex. Synonym: ataxic breathing, Biot's breathing, respiratory ataxia. (05 Mar 2000) |
| bronchial respiration | A tubular blowing sound caused by the passage of air through a bronchus in an area of consolidated lung tissue. (05 Mar 2000) |
