la·bored res·pi·ra·tion

difficult, usually deep, breathing in patients with cardiac or pulmonary disease or disease affecting nervous system control of ventilation.

labored respiration

Respiration that involves active participation of accessory inspiratory and expiratory muscles; dyspnea.

la·bor·ed res·pi·ra·tion

(lābŏrd respir-āshŭn)
Difficult, usually deep, breathing in patients with cardiac or pulmonary disease.


1. the exchange of oxygen and carbon dioxide between the atmosphere and the body cells, including inspiration and expiration, diffusion of oxygen from the pulmonary alveoli to the blood and of carbon dioxide from the blood to the alveoli, and the transport of oxygen to and carbon dioxide from the body cells.
2. cellular respiration, the metabolic processes by which living cells break down carbohydrates, amino acids and fats to produce energy in the form of ATP (adenosine triphosphate).

abdominal respiration
inspiration and expiration accomplished mainly by the abdominal muscles and diaphragm. Occurs in acute pleurisy because of pain in the chest and fixation of the thorax, and tick paralysis due to paralysis of the intercostal muscles.
aerobic respiration
oxidative transformation of certain substrates into secretory products, the released energy being used in the process of assimilation.
anaerobic respiration
respiration in which energy is released by chemical reactions in which free oxygen takes no part.
artificial respiration
that maintained by force applied to the body. Called also artificially assisted respiration.
artificially assisted respiration
see artificial respiration (above).
Biot's r's
rapid, deep respirations with abrupt pauses in breathing. See also biot's respirations.
cell respiration
the processes in the living cell by which organic substances are oxidized and chemical energy is released.
Cheyne-Stokes respiration
breathing characterized by rhythmic waxing and waning of respiration depth, with regularly recurring apneic periods. See also cheyne-stokes respiration.
cogwheel respiration
breathing with jerky inspiration.
controlled respiration
during general anesthesia using an endotracheal tube with an inflated cuff, the animal's respiration can be controlled completely by compression alternating with relaxation on the rebreathing bag of the breathing circuit. See also intermittent positive-pressure ventilation.
costal respiration
the respiratory movements are mostly carried out by the chest wall.
diaphragmatic respiration
that performed mainly by the diaphragm.
electrophrenic respiration
induction of respiration by electric stimulation of the phrenic nerve.
external respiration
the exchange of gases between the lungs and the blood.
internal respiration
the exchange of gases between the body cells and the blood.
Kussmaul's respiration
labored respiration
see dyspnea.
respiration monitors
machines that monitor respiratory movement and efficiency are most desirable during anesthesia. They include rate monitors, apnea alarms, tidal and minute volume monitoring respirometers, infrared gas analyzers to measure carbon dioxide content of end-tidal air,
paradoxical respiration
that in which a lung, or a portion of a lung, is deflated during inspiration and inflated during expiration. See also paradoxical respiration.
tissue respiration
internal respiration.
