Fig. 6: Shallow breathing using rib muscles. Shallow breathing, thoracic breathing, costal breathing or chest breathing [1] is the drawing of minimal breath into the lungs, usually by drawing air into the chest area using the intercostal muscles rather than throughout the lungs via the diaphragm. Shallow breathing can result in or be ...
The muscles of respiration are the muscles that contribute to inhalation and exhalation, by aiding in the expansion and contraction of the thoracic cavity. The diaphragm and, to a lesser extent, the intercostal muscles drive respiration during quiet breathing .
[30] [31] Hypopnea refers to overly shallow breathing; hyperpnea refers to fast and deep breathing brought on by a demand for more oxygen, as for example by exercise. The terms hypoventilation and hyperventilation also refer to shallow breathing and fast and deep breathing respectively, but under inappropriate circumstances or disease. However ...
The muscle fibres of the diaphragm radiate outward from the central tendon. While the diaphragm is one muscle, it is composed of two distinct muscle regions: the costal, which serves as the driver in the work of breathing, and crural diaphragm, which serves as an "anchor;" attaching the muscle to the lower ribs and lumbar vertebrae.
Hyperpnea – fast and deep breathing; Hyperventilation – increased breathing that causes CO 2 loss; Hypopnea – slow and shallow breathing; Hypoventilation – decreased breathing that causes CO 2 gain; Labored breathing – physical presentation of respiratory distress; Tachypnea – increased breathing rate
The normal relaxed state of the lung and chest is partially empty. Further exhalation requires muscular work. Inhalation is an active process requiring work. [4] Some of this work is to overcome frictional resistance to flow, and part is used to deform elastic tissues, and is stored as potential energy, which is recovered during the passive process of exhalation, Tidal breathing is breathing ...

Eupnea is an efficient and effective form of breathing, which balances between maximizing air intake, and minimizing muscular effort. During eupnea, neural output to respiratory muscles is highly regular and stable, with rhythmic bursts of activity during inspiration only to the diaphragm and external intercostal muscles.
