Clinically-dead
Clinical death is the medical term for cessation of blood circulation and breathing, the two criteria necessary to sustain the lives of human beings and of many other organisms. It occurs when the heart stops beating in a regular rhythm, a condition called cardiac arrest. The term is also sometimes used in resuscitation research. Stopped blood circulation has historically proven irreversible in most cases. Prior to the invention of cardiopulmonary resuscitation (CPR), defibrillation, epinephrine injection, and other treatments in the 20th century, the absence of blood circulation (and vital functions related to blood circulation) was historically considered the official definition of death. With the advent of these strategies, cardiac arrest came to be called ''clinical death'' rather than simply ''death'', to reflect the possibility of post-arrest resuscitation. At the onset of clinical death, consciousness is lost within several seconds, and in dogs, measurable brain activity has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Term
Medical terminology is a language used to precisely describe the human body including all its components, processes, conditions affecting it, and procedures performed upon it. Medical terminology is used in the field of medicine Medical terminology has quite regular morphology, the same prefixes and suffixes are used to add meanings to different roots. The root of a term often refers to an organ, tissue, or condition. For example, in the disorder known as hypertension, the prefix "hyper-" means "high" or "over", and the root word "tension" refers to pressure, so the word "hypertension" refers to abnormally high blood pressure. The roots, prefixes and suffixes are often derived from Greek or Latin, and often quite dissimilar from their English-language variants. This regular morphology means that once a reasonable number of morphemes are learnt it becomes easy to understand very precise terms assembled from these morphemes. Much medical language is anatomical terminology, concern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Q10 (temperature Coefficient)
The ''Q''10 temperature coefficient is a measure of temperature sensitivity based on the chemical reactions. The ''Q''10 is calculated as: : Q_=\left( \frac \right )^ where; : ''R'' is the rate : ''T'' is the temperature in Celsius degrees or kelvin. : Rewriting this equation, the assumption behind ''Q''10 is that the reaction rate ''R'' depends exponentially on temperature: : R_2 = R_1 ~Q_^ ''Q''10 is a unitless quantity, as it is the factor by which a rate changes, and is a useful way to express the temperature dependence of a process. For most biological systems, the ''Q''10 value is ~ 2 to 3. In muscle performance The temperature of a muscle has a significant effect on the velocity and power of the muscle contraction, with performance generally declining with decreasing temperatures and increasing with rising temperatures. The ''Q''10 coefficient represents the degree of temperature dependence a muscle exhibits as measured by contraction rates. A ''Q''10 of 1.0 indic ...

Brain Death
Brain death is the permanent, irreversible, and complete loss of brain function which may include cessation of involuntary activity necessary to sustain life. It differs from persistent vegetative state, in which the person is alive and some autonomic functions remain. It is also distinct from comas as long as some brain and bodily activity and function remain, and it is also not the same as the condition locked-in syndrome. A differential diagnosis can medically distinguish these differing conditions. Brain death is used as an indicator of legal death in many jurisdictions, but it is defined inconsistently and often confused by the public. Various parts of the brain may keep functioning when others do not anymore, and the term "brain death" has been used to refer to various combinations. For example, although one major medical dictionary considers "brain death" to be synonymous with "cerebral death" (death of the cerebrum), the US National Library of Medicine Medical Subject ...

Do Not Resuscitate
A do-not-resuscitate order (DNR), also known as Do Not Attempt Resuscitation (DNAR), Do Not Attempt Cardiopulmonary Resuscitation (DNACPR), no code or allow natural death, is a medical order, written or oral depending on country, indicating that a person should not receive cardiopulmonary resuscitation (CPR) if that person's heart stops beating. Sometimes these decisions and the relevant documents also encompass decisions around other critical or life-prolonging medical interventions. The legal status and processes surrounding DNR orders vary from country to country. Most commonly, the order is placed by a physician based on a combination of medical judgement and patient involvement. Basis for choice Interviews with 26 DNR patients and 16 full code patients in Toronto in 2006-9 suggest that the decision to choose do-not-resuscitate status was based on personal factors including health and lifestyle; relational factors (to family or to society as a whole); and philosophical f ...

Legal Death
Legal death is the recognition under the law of a particular jurisdiction that a person is no longer alive. In most cases, a doctor's declaration of death (variously called) or the identification of a corpse is a legal requirement for such recognition. A person who has been missing for a sufficiently long period of time (typically at least several years) may be presumed or declared legally dead, usually by a court. When a death has been registered in a civil registry, a death certificate may be issued. Such death certificate may be required in a number of legal situations, such as applying for probate, claiming some benefits or making an insurance claim, etc. Medical declaration Most legal determinations of death in the developed world are made by medical professionals who pronounce death when specific criteria are met. Two categories of legal death are death determined by irreversible cessation of heartbeat (cardiopulmonary death), and death determined by irreversible cessation of ...

Advanced Cardiac Life Support
Advanced cardiac life support, advanced cardiovascular life support (ACLS) refers to a set of clinical guidelines for the urgent and emergent treatment of life-threatening cardiovascular conditions that will cause or have caused cardiac arrest, using advanced medical procedures, medications, and techniques. ACLS expands on Basic Life Support (BLS) by adding recommendations on additional medication and advanced procedure use to the CPR guidelines that are fundamental and efficacious in BLS. ACLS is practiced by advanced medical providers including physicians, some nurses and paramedics; these providers are usually required to hold certifications in ACLS care. While "ACLS" is almost always semantically interchangeable with the term "Advanced Life Support" (ALS), when used distinctly, ACLS tends to refer to the immediate cardiac care, while ALS tends to refer to more specialized resuscitation care such as ECMO and PCI. In the EMS community, "ALS" may refer to the advanced care prov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
