accelerated idioventricular rhythm (s)
, accelerated idioventricular rhythms (pl) (nouns)
A rapid ventricular rhythm, approximately 60 to 110 beats per minute: "Accelerated idioventricular rhythm usually results from premature beats or an escape rhythm generated by the slowing of the sinus pacemaker or acceleration of a ventricular pacemaker."
Mechanical ventilation used in assisting breathing when deficient, or completely assuming control of breathing in the presence of apnea (non breathing).
Mechanical ventilation that takes the place of natural inspiration and expiration in th management of pulmonary insufficiency.
A geyser on the sea bottom through which super-hot aqueous solutions rise from the magma beneath the crust.
This creates a surrounding system of mineral-rich water that helps to support a distinctive type of ecosystem not found in typical cold-water environments at the same ocean depth.

A condition of breathing faster and/or deeper than necessary, bringing about light headedness and other undesirable symptoms often associated with panic attacks.
hyperventilation (high" pur ven" t'l AY shuhn)

1. Abnormally slow and shallow respiration, resulting in an increased level of carbon dioxide in the blood.
2. A condition in which there is a reduced amount of air entering the pulmonary (lung) alveoli (small cell containing air in the lungs), resulting in decreased levels of oxygen and increased levels of carbon dioxide in the blood.
Hypoventilation can be a result of breathing that is too shallow (hypopnea) or too slow (bradypnea) or to diminished lung function.
An apparatus for artificial ventilation of a patient who has weak or paralyzed respiratory muscles, consisting of a rigid tank which encloses the body from the neck down.
Changes of pressure of air within the tank bring about inspiration and expiration.
