Flashcards: Respiration

Acrocyanosis is persistent blue or cyanotic discoloration of the extremities, most commonly occurring in the hands, although it also occurs in the feet and distal parts of face.

Compressed air is air kept under a pressure that is greater than atmospheric pressure.

Hypoxemia (or hypoxaemia in British English) is an abnormally low level of oxygen in the blood.

Red blood cells (RBCs), also called erythrocytes, are the most common type of blood cell and the vertebrate organism's principal means of delivering oxygen (O2) to the body tissues—via blood flow through the circulatory system.

Stridor (Latin for "creaking or grating noise") is a high-pitched breath sound resulting from turbulent air flow in the larynx or lower in the bronchial tree.

Erotic asphyxiation or breath control play is the intentional restriction of oxygen to the brain for the purposes of sexual arousal.

Sleep apnea is a sleep disorder characterized by pauses in breathing or periods of shallow breathing during sleep.

Breathing is the process that moves air in and out of the lungs, or the diffusion of oxygen and carbon dioxide to and from the external environment into and out of the blood through other respiratory organs such as gills.

Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level.

Strangling is compression of the neck that may lead to unconsciousness or death by causing an increasingly hypoxic state in the brain.

Kussmaul breathing is a deep and labored breathing pattern often associated with severe metabolic acidosis, particularly diabetic ketoacidosis (DKA) but also kidney failure.

A stertor is a respiratory sound characterized by heavy snoring or gasping.

Hyperventilation syndrome (HVS); also chronic hyperventilation syndrome (CHVS) and dysfunctional breathing hyperventilation syndrome is a respiratory disorder, psychologically or physiologically based, involving breathing too deeply or too rapidly (hyperventilation).

The aortic body is one of several small clusters of chemoreceptors, baroreceptors, and supporting cells located along the aortic arch.

The muscles of respiration are those muscles that contribute to inhalation and exhalation, by aiding in the expansion and contraction of the thoracic cavity.

The carotid body (carotid glomus or glomus caroticum) is a small cluster of chemoreceptors and supporting cells located near the fork (bifurcation) of the carotid artery (which runs along both sides of the throat).

Aquatic respiration is the process whereby an aquatic animal obtains oxygen from water.

Exercise-induced asthma, or E.

Histotoxic hypoxia (also called histoxic hypoxia) is the inability of cells to take up or utilize oxygen from the bloodstream, despite physiologically normal delivery of oxygen to such cells and tissues.

The General Service Respirator is a military gas mask designed to replace the previous S10 respirator for the British Armed Forces.

The trachealis muscle is a smooth muscle that bridges the gap between the free ends of C-shaped cartilages at the posterior border of the trachea, adjacent to the esophagus.

The pre-Bötzinger complex (preBötC) is a cluster of interneurons in the ventrolateral medulla of the brainstem.

Work of breathing (WOB) is the energy expended to inhale and exhale a breathing gas.
