Code Blue (emergency Code)
Hospital emergency codes are coded messages often announced over a public address system of a hospital to alert staff to various classes of on-site emergencies. The use of codes is intended to convey essential information quickly and with minimal misunderstanding to staff while preventing stress and panic among visitors to the hospital. Such codes are sometimes posted on placards throughout the hospital or are printed on employee identification badges for ready reference. Hospital emergency codes have varied widely by location, even between hospitals in the same community. Confusion over these codes has led to the proposal for and sometimes adoption of standardized codes. In many American, Canadian, New Zealand and Australian hospitals, for example "code blue" indicates a patient has entered cardiac arrest, while "code red" indicates that a fire has broken out somewhere in the hospital facility. In order for a code call to be useful in activating the response of specific hospital p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Address System
A public address system (or PA system) is an electronic system comprising microphones, amplifiers, loudspeakers, and related equipment. It increases the apparent volume (loudness) of a human voice, musical instrument, or other acoustic sound source or recorded sound or music. PA systems are used in any public venue that requires that an announcer, performer, etc. be sufficiently audible at a distance or over a large area. Typical applications include sports stadiums, public transportation vehicles and facilities, and live or recorded music venues and events. A PA system may include multiple microphones or other sound sources, a mixing console to combine and modify multiple sources, and multiple amplifiers and loudspeakers for louder volume or wider distribution. Simple PA systems are often used in small venues such as school auditoriums, churches, and small bars. PA systems with many speakers are widely used to make announcements in public, institutional and commercial buildings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saskatchewan Health Authority
The Saskatchewan Health Authority (SHA) is the single health region of the province of Saskatchewan. Established on December 4, 2017, it amalgamated the province's 12 former regional health authorities into one unified organization. The SHA is responsible for delivering a wide range of health services, including primary, secondary, tertiary, and quaternary care, as well as home and community care, mental health services, population and preventive health, and addiction services. History The formation of the SHA was a significant restructuring of Saskatchewan's healthcare system. This change aimed to provide more consistent and coordinated care across the province. The transition was guided by recommendations from the Saskatchewan Advisory Panel on Health System Structure, which emphasized the need for a single provincial health authority to improve efficiency and patient care. Governance The SHA is governed by a Board of Directors appointed by the Lieutenant Governor in Council ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Status Epilepticus
Status epilepticus (SE), or status seizure, is a medical condition with abnormally prolonged seizures. It can have long-term consequences, manifesting as a single seizure lasting more than a defined time (time point 1), or 2 or more seizures over the same period without the person returning to normal between them. The seizures can be of the Generalized tonic–clonic seizure, tonic–clonic type, with a regular pattern of contraction and extension of the arms and legs, also known as convulsive status epilepticus, or of types that do not involve contractions, such as absence seizures or complex partial seizures. Convulsive status epilepticus is a life-threatening medical emergency, particularly if treatment is delayed. For convulsive status epilepticus, the most dangerous type, 5 minutes is the time point at which the seizure or seizures would be considered status epilepticus, so this is defined as a convulsion lasting more than 5 minutes, or two convulsions within 5 minutes without ...

Blood Type
A blood type (also known as a blood group) is based on the presence and absence of antibody, antibodies and Heredity, inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system. Some of these antigens are also present on the surface of other types of Cell (biology)#Eukaryotic cells, cells of various Tissue (biology), tissues. Several of these red blood cell surface antigens can stem from one allele (or an alternative version of a gene) and collectively form a blood group system. Blood types are inherited and represent contributions from both parents of an individual. As of October 2024, a total of 47 human blood group systems are recognized by the International Society of Blood Transfusion (ISBT). The two most important blood group systems are ABO blood group system, ABO and Rh blood group system, Rh; they determine someone's blood type (A, B, AB, and O ...

Cross-matching
Cross-matching or crossmatching is a test performed before a blood transfusion as part of blood compatibility testing. Normally, this involves adding the recipient's blood plasma to a sample of the donor's red blood cells. If the blood is incompatible, the antibodies in the recipient's plasma will bind to antigens on the donor red blood cells. This antibody-antigen reaction can be detected through visible clumping or destruction of the red blood cells, or by reaction with anti-human globulin. Along with blood typing of the donor and recipient and screening for unexpected blood group antibodies, cross-matching is one of a series of steps in pre-transfusion testing. In some circumstances, an electronic cross-match can be performed by comparing records of the recipient's ABO and Rh blood type against that of the donor sample. In emergencies, blood may be issued before cross-matching is complete. Cross-matching is also used to determine compatibility between a donor and recipien ...

Platelets
Platelets or thrombocytes () are a part of blood whose function (along with the coagulation factors) is to react to bleeding from blood vessel injury by clumping to form a blood clot. Platelets have no cell nucleus; they are fragments of cytoplasm from megakaryocytes which reside in bone marrow or lung tissue, and then enter the circulation. Platelets are found only in mammals, whereas in other vertebrates (e.g. birds, amphibians), thrombocytes circulate as intact mononuclear cells. One major function of platelets is to contribute to hemostasis: the process of stopping bleeding at the site where the lining of vessels (endothelium) has been interrupted. Platelets gather at the site and, unless the interruption is physically too large, they plug the hole. First, platelets attach to substances outside the interrupted endothelium: ''adhesion''. Second, they change shape, turn on receptors and secrete chemical messengers: ''activation''. Third, they connect to each other throu ...

Fresh Frozen Plasma
Fresh frozen plasma (FFP) is a blood product made from the liquid portion of whole blood. It is used to treat conditions in which there are low blood clotting factors (INR > 1.5) or low levels of other blood proteins. It may also be used as the replacement fluid in plasma exchange. Using ABO compatible plasma, while not required, may be recommended. Use as a volume expander is not recommended. It is administered by intravenous, slow injection into a vein. Side effects include nausea and itchiness. Rarely there may be allergic reactions, blood clots, or infections. It is unclear if use during pregnancy or breastfeeding is safe for the baby. Greater care should be taken in people with protein S deficiency, IgA deficiency, or heart failure. Fresh frozen plasma is made up of a complex mixture of water, proteins, carbohydrates, fats, and vitamins. When frozen it lasts about a year. Plasma first came into medical use during the Second World War. It is on the WHO Model List of Essenti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Packed Red Blood Cells
Red blood cell concentrates, also known as red cell concentrates or packed red blood cells, are red blood cells that have been separated for blood transfusion. A red blood cell concentrate typically has a haematocrit of 0.50 – 0.70 L/L and a volume between 250 and 320 mL. Transfusion of red blood cell concentrates is indicated to compensate for a deficit caused by critical bleeding or to correct anaemic conditions, in order to increase the oxygen-carrying capacity and avoid detrimental effects caused by oxygen debt. In adults, one unit brings up hemoglobin levels by about 10 g/L (1 g/dL). Repeated transfusions may be required in people receiving cancer chemotherapy or who have haemoglobin disorders. Cross-matching may be required before the blood is given. A red blood cell concentrate is given by injection into a vein. The widespread use of red blood cell concentrates as part of blood component therapy began in the middle of the 20th century, when polyvinyl chloride (PVC ...

Blood Transfusion
Blood transfusion is the process of transferring blood products into a person's Circulatory system, circulation intravenously. Transfusions are used for various medical conditions to replace lost components of the blood. Early transfusions used whole blood, but modern medical practice commonly uses only components of the blood, such as red blood cells, blood plasma, plasma, platelets, and other clotting factors. White blood cells are transfused only in very rare circumstances, since granulocyte transfusion has limited applications. Whole blood has come back into use in the Major trauma, trauma setting. Red blood cells (RBC) contain hemoglobin and supply the Cell (biology), cells of the body with oxygen. White blood cells are not commonly used during transfusions, but they are part of the immune system and also fight infections. Plasma is the "yellowish" liquid part of blood, which acts as a buffer and contains proteins and other important substances needed for the body's overall ...

District Nurse
District nurses work manage care within the community and lead teams of community nurses and support workers. In the United Kingdom, the role requires registered nurses to take a Nursing and Midwifery Council (NMC) approved specialist practitioner course. Duties generally include visiting house-bound patients and providing advice and care such as palliative care, wound management, catheter and continence care and medication support. Their work involves both follow-up care for recently discharged hospital inpatients and longer-term care for chronically ill patients who may be referred by many other services, as well as working collaboratively with general practitioners in preventing unnecessary or avoidable hospital admissions. District nurses may also be known as community nurse specialists. History Organised district nursing is considered to have begun in England in 1859. In 1858 Liverpool philanthropist William Rathbone employed a nurse, Mary Robinson, to take care of his w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Practitioner
A general practitioner (GP) is a doctor who is a Consultant (medicine), consultant in general practice. GPs have distinct expertise and experience in providing whole person medical care, whilst managing the complexity, uncertainty and risk associated with the continuous care they provide. GPs work at the heart of their communities, striving to provide comprehensive and equitable care for everyone, taking into account their health care needs, stage of life and background. GPs work in, connect with and lead multidisciplinary teams that care for people and their families, respecting the context in which they live, aiming to ensure all of their physical health and mental health needs are met. They are trained to treat patients to levels of complexity that vary between countries. The term "primary care physician" is used in the United States. A core element in general practice is continuity of care, that bridges episodes of various illnesses over time. Greater continuity with a gen ...
