| paradoxical respiration | Deflation of the lung during inspiration and inflation of the lung during the phase of expiration; seen in the lung on the side of an open pneumothorax. (05 Mar 2000) |
|---|---|
| vesicular respiration | The respiratory murmur heard on auscultating over the normal lung. Synonym: respiratory murmur, vesicular murmur. (05 Mar 2000) |
| vesiculocavernous respiration | Cavernous respiration, due to the presence of a cavity, mingled with the vesicular murmur of the surrounding normal lung tissue. (05 Mar 2000) |
| cavernous respiration | A hollow reverberating sound heard on auscultation over a cavity in the lung. (05 Mar 2000) |
| cell respiration | The exergonic metabolic processes in living cells, animal or plant, by which molecular oxygen is taken in, organic substances are oxidised, free energy is released, and carbon dioxide, water, and other oxidised products are given off by the cell. (12 Dec 1998) |
| cellular respiration | <biochemistry> The conversion within the cell of nutrients (such as sugar molecules) into chemical energy in the form of ATP, by reacting the food with oxygen (O2) until the food has completely been degraded into carbon dioxide and H2O. (09 Oct 1997) |
| respiration | <physiology> Term used by physiologists to describe the process of breathing and by biochemists to describe the intracellular oxidation of substrates coupled with production of ATP and oxidized coenzymes (NAD and FAD). This form of respiration may be anaerobic as in glycolysis or aerobic in the case of oxidations operating via the tricarboxylic acid cycle and the electron transport chain. (18 Nov 1997) |
| respiration disorders | Diseases of the respiratory system in general or unspecified or for a specific respiratory disease not available. (12 Dec 1998) |
| respiration rate | Frequency of breathing, recorded as the number of breaths per minute. (05 Mar 2000) |
| cheyne-stokes respiration | A pattern of breathing with a gradual increase in the depth of respiration to a maximum, followed by a progressive decrease in the depth of respiration resulting in apnoea, characteristically seen in coma associated with severe neurological insult. (27 Sep 1997) |
| cogwheel respiration | The inspiratory sound being broken into two or three by silent intervals. Synonym: interrupted respiration, jerky respiration. (05 Mar 2000) |
| mouth-to-mouth respiration | A method of artificial ventilation involving an overlap of the patient's mouth (and nose in small children) with the operator's mouth to inflate the patient's lungs by blowing, followed by an unassisted expiratory phase brought about by elastic recoil of the patient's chest and lungs; repeated 12 to 16 times a minute; where the nose is not covered by the operator's mouth, the nostrils must be closed by pinching. (05 Mar 2000) |
| costal respiration | Respiration effected chiefly by the action of the intercostal and other muscles that raise the ribs, causing expansion of the chest. Synonym: costal respiration. (05 Mar 2000) |
| positive-pressure respiration | A method of mechanical ventilation in which pressure is maintained to increase the volume of gas remaining in the lungs at the end of expiration, thus reducing the shunting of blood through the lungs and improving gas exchange. (12 Dec 1998) |
| positive-pressure respiration, intrinsic | Non-therapeutic positive end-expiratory pressure occurring frequently in patients with severe airway obstruction. It can appear with or without the administration of external positive end-expiratory pressure (positive-pressure respiration). It presents an important load on the inspiratory muscles which are operating at a mechanical disadvantage due to hyperinflation. Auto-peep may cause profound hypotension that should be treated by intravascular volume expansion, increasing the time for expiration, and/or changing from assist mode to intermittent mandatory ventilation mode.
