Agonal Respiration
Agonal respiration, gasping respiration or agonal breathing is a distinct abnormal pattern of breathing and brainstem reflex characterized by gasping, labored breathing, accompanied by strange vocalizations and myoclonus. Possible causes include cerebral ischemia, extreme hypoxia (inadequate oxygen supply to tissue), or even anoxia (total depletion of oxygen). Agonal breathing is an extremely serious medical sign requiring immediate medical attention, as the condition generally progresses to complete apnea and heralds death. The duration of agonal respiration can be as brief as two breaths or last up to several hours. The term is sometimes (inaccurately) used to refer to labored, gasping breathing patterns accompanying organ failure (e.g. liver failure and kidney failure), SIRS, septic shock, and metabolic acidosis (see Kussmaul breathing, or in general any labored breathing, including Biot's respirations and ataxic respirations). Correct usage would restrict the term t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breath
Breathing (or ventilation) is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen. All aerobic creatures need oxygen for cellular respiration, which extracts energy from the reaction of oxygen with molecules derived from food and produces carbon dioxide as a waste product. Breathing, or "external respiration", brings air into the lungs where gas exchange takes place in the alveoli through diffusion. The body's circulatory system transports these gases to and from the cells, where "cellular respiration" takes place. The breathing of all vertebrates with lungs consists of repetitive cycles of inhalation and exhalation through a highly branched system of tubes or airways which lead from the nose to the alveoli. The number of respiratory cycles per minute is the breathing or respiratory rate, and is one of the four primary vital signs of life. Under normal conditions t ...

Systemic Inflammatory Response Syndrome
Systemic inflammatory response syndrome (SIRS) is an inflammatory state affecting the whole body. It is the body's response to an infectious or noninfectious insult. Although the definition of SIRS refers to it as an "inflammatory" response, it actually has pro- and anti-inflammatory components. Presentation Complications SIRS is frequently complicated by failure of one or more organs or organ systems. The complications of SIRS include * Acute kidney injury * Shock * Multiple organ dysfunction syndrome Causes The causes of SIRS are broadly classified as infectious or noninfectious. Causes of SIRS include: * bacterial infections * severe malaria * trauma * burns * pancreatitis * ischemia * hemorrhage Other causes include: * Complications of surgery * Adrenal insufficiency * Pulmonary embolism * Complicated aortic aneurysm * Cardiac tamponade * Anaphylaxis * Drug overdose Diagnosis SIRS is a serious condition related to systemic inflammation, organ dysfunction, and organ fail ...

King County, Washington
King County is located in the U.S. state of Washington. The population was 2,269,675 in the 2020 census, making it the most populous county in Washington, and the 13th-most populous in the United States. The county seat is Seattle, also the state's most populous city. King County is one of three Washington counties that are included in the Seattle– Tacoma–Bellevue metropolitan statistical area. (The others are Snohomish County to the north, and Pierce County to the south.) About two-thirds of King County's population lives in Seattle's suburbs. History When Europeans arrived in the region that would become King County, it was inhabited by several Coast Salish groups. Villages around the site that would become Seattle were primarily populated by the Duwamish people. The Snoqualmie Indian Tribe occupied the area that would become eastern King County. The Green River and White River were home for the Muckleshoot tribal groups. In the first winter after the Denny Party lande ...

Cardiac Arrest
Cardiac arrest is when the heart suddenly and unexpectedly stops beating. It is a medical emergency that, without immediate medical intervention, will result in sudden cardiac death within minutes. Cardiopulmonary resuscitation (CPR) and possibly defibrillation are needed until further treatment can be provided. Cardiac arrest results in a rapid loss of consciousness, and breathing may be abnormal or absent. While cardiac arrest may be caused by heart attack or heart failure, these are not the same, and in 15 to 25% of cases, there is a non-cardiac cause. Some individuals may experience chest pain, shortness of breath, nausea, an elevated heart rate, and a light-headed feeling immediately before entering cardiac arrest. The most common cause of cardiac arrest is an underlying heart problem like coronary artery disease that decreases the amount of oxygenated blood supplying the heart muscle. This, in turn, damages the structure of the muscle, which can alter its function. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ataxic Respiration
Ataxic respiration is an abnormal pattern of breathing characterized by complete irregularity of breathing, with irregular pauses and increasing periods of apnea. As the breathing pattern deteriorates, it merges with agonal respiration. Cause It is caused by damage to the medulla oblongata due to strokes or trauma. It generally indicates a poor prognosis, and usually progresses to complete apnea. The term is sometimes used interchangeably with Biot's respiration. Treatment It is believed that intensive care technology may be masking the presence of Biot’s Respirations. This could be related to the fact that treatment for Biot’s Respirations typically results with intubation immediately upon diagnosis, with mechanical ventilation Mechanical ventilation, assisted ventilation or intermittent mandatory ventilation (IMV), is the medical term for using a machine called a ventilator to fully or partially provide artificial ventilation. Mechanical ventilation helps move air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
