| electrophrenic respiration | The rhythmical electrical stimulation of the phrenic nerve by an electrode applied to the skin at the motor points of the phrenic nerve; it is used in paralysis of the respiratory centre resulting from acute bulbar poliomyelitis. (05 Mar 2000) |
|---|---|
| tubular respiration | High-pitched bronchial respiration. (05 Mar 2000) |
| jerky respiration | The inspiratory sound being broken into two or three by silent intervals. Synonym: interrupted respiration, jerky respiration. (05 Mar 2000) |
| external respiration | The exchange of respiratory gases in the lungs as distinguished from internal or tissue respiration. (05 Mar 2000) |
| Kussmaul-Kien respiration | Deep, rapid respiration characteristic of diabetic or other causes of acidosis. Synonym: Kussmaul-Kien respiration. (05 Mar 2000) |
| Kussmaul respiration | Deep, rapid respiration characteristic of diabetic or other causes of acidosis. Synonym: Kussmaul-Kien respiration. (05 Mar 2000) |
| laboured respiration | <chest medicine> Difficult, usually deep, breathing in patients with cardiac or pulmonary disease or disease affecting nervous system control of ventilation. (05 Mar 2000) |
| forced respiration | Voluntary hyperventilation. (05 Mar 2000) |
| bone scan: falsely negative metastases | <radiology> Anaplastic tumours, reticulum cell sarcoma, renal cell carcinoma, thyroid carcinoma, histiocytosis, neuroblastoma, multiple myeloma (positive scan usually due to recent or impending fracture) (12 Dec 1998) |
| gram-negative | <microbiology> A common class of bacteria normally found in the gastrointestinal tract that can be responsible for disease in man (sepsis). Bacteria are considered to be gram-negative because of their characteristic staining properties under the microscope, where they either do not stain or are decolourised by alcohol during Gram's method of staining. This is a primary characteristic of bacteria that have a cell wall composed of a thin layer of peptidoglycan covered by an outer membrane of lipoprotein and lipopolysaccharide containing endotoxin. The gram staining characteristics of bacteria have resulted in an important classification system for the identification of bacteria. See: gram-positive (06 Oct 1997) |
| gram-negative aerobic bacteria | <microbiology> A large group of aerobic bacteria which show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
| gram-negative aerobic rods and cocci | <microbiology> A group of gram-negative bacteria consisting of rod- and coccus-shaped cells. They are both aerobic (able to grow under an air atmosphere) and microaerophilic (grow better in low concentrations of oxygen) under nitrogen-fixing conditions but, when supplied with a source of fixed nitrogen, they grow as aerobes. (12 Dec 1998) |
| gram-negative anaerobic bacteria | <microbiology> A large group of anaerobic bacteria which show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
| gram-negative anaerobic cocci | <microbiology> A group of anaerobic coccoid bacteria that show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
| gram-negative anaerobic straight, curved, and helical rods | <microbiology> A group of anaerobic, rod-shaped bacteria that show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
