Sleep Disorder Glossary Cheyne–Stokes respiration /ˈtʃeɪnˈstoʊks/ is an abnormal pattern of breathing characterized by progressively deeper and sometimes faster breathing, followed by a gradual decrease that results in a temporary stop in breathing called an apnea. The pattern repeats, with each cycle usually taking 30 seconds to 2 minutes.

- A normal respiratory rate is termed eupnea, an increased respiratory rate is termed tachypnea and a lower-than-normal respiratory rate is termed bradypnea. Breathing (which in organisms with lungs is called ventilation and includes inhalation and exhalation) is a part of respiration.easurement [edit]. Human respiration rate is measured when a person is at rest and involves counting the number of breaths for one minute by counting how many times the chest rises.

Causes of tachypnea Tachypnea. Tachypnea is defined as increased breathing speed, above the standard respiratory rate of 14 to 20 inhales per minute. Tachypnea increases the so-called minute ventilation and also, if the inhale volume is smaller, tachypnea only compensates for decreased air volume, which is used in each respiration cycle.

- Agonal respiration refers to the irregular breathing pattern that usually occurs prior to a terminally ill patient's death. CPR should be administered immediately to cardiac arrest patients who are experiencing agonal respiration.

Tachypnea Tachypnea or tachypnoea is abnormally rapid breathing. In adult humans at rest, any respiratory rate between 12 and 20 breaths per minute is normal and tachypnea is indicated by a rate greater than 20 breaths per minute. Children have significantly higher resting ventilatory rates, which decline rapidly during the first three years of life and then steadily until around 18 years. Tachypnea can be an early medical sign of pneumonia in children.

Control of ventilation Respiration refers to the utilization of oxygen and production of carbon dioxide by the body as a whole, or by individual cells. Under most conditions, the partial pressure of carbon dioxide ( P C O 2 {\displaystyle P_{{\mathrm {CO} }_{2}}} ) controls the rate of pulmonary ventilation.

Cheyne-Stokes respiration In 1854 Stokes used Cheyne's observations on respiration as a point of departure and wrote an extended description of the condition now known as Cheyne-Stokes respiration.

PhysiologyRespiration: ventilation Ventilation is the process by which air moves into and out of the lungs and is made available for gas exchange. The physiological control of ventilation is an entire article itself (see Further reading); below is a summary of the mechanisms involved in ventilatory control.

Breathing Breathing (or respiration, or ventilation) is the process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly by bringing in oxygen and flushing out carbon dioxide.

Central neurogenic hyperventilation A cross-section diagram of the area of the brain typically affected by tumors in the condition CNH. Central neurogenic hyperventilation (CNH) is an abnormal pattern of breathing characterized by deep and rapid breaths at a rate of at least 25 breaths per minute. Increasing irregularity of this respiratory rate generally is a sign that the patient will enter into coma. CNH is unrelated to other forms of hyperventilation, like Kussmaul's respirations. CNH is the human body's response to reduced carbon dioxide levels in the blood.

Central hypoventilation syndrome [edit on Wikidata] Central hypoventilation syndrome (CHS) is a respiratory disorder that results in respiratory arrest during sleep. CHS can either be congenital (CCHS) or acquired (AHCS) later in life. It is fatal if untreated. It is also known by Ondine's curse.

- Cutaneous respiration is a type of respiration that is done through  the skin. The body surface of the organism is vascularized enough  to allow gas to pass in and out. 1 person found this useful. Edit.his variety of lupus is less severe, in that it attacks the skin only. However, it can be disfiguring, often attacking the skin of the face. The term discoid is derived from … the round (disc-shaped) lesions.
