Cardiac Monitoring
Cardiac monitoring generally refers to continuous or intermittent monitoring (medicine), monitoring of heart activity to assess a patient's condition relative to their cardiac cycle, cardiac rhythm. Cardiac monitoring is usually carried out using electrocardiography, which is a Non-invasive procedure, noninvasive process that records the Cardiac conduction system, heart's electrical activity and displays it in an electrocardiogram. It is different from hemodynamics, hemodynamic monitoring, which monitors the blood pressure, pressure and blood flow, flow of blood within the circulatory system#Human cardiovascular system, cardiovascular system. The two may be performed simultaneously on critical care medicine, critical heart patients. Cardiac monitoring for ambulatory patients (those well enough to walk around) is known as ambulatory electrocardiography and uses a small, wearable device, such as a Holter monitor, wireless ambulatory ECG, or an implantable loop recorder.

Holter Monitor
In medicine, a Holter monitor (often simply Holter) is a type of ambulatory electrocardiography device, a portable device for cardiac monitoring (the monitoring of the electrical activity of the cardiovascular system) for at least 24 hours. The Holter's most common use is for monitoring ECG heart activity (electrocardiography or ECG). Its extended recording period is sometimes useful for observing occasional cardiac arrhythmias which would be difficult to identify in a shorter period. For patients having more transient symptoms, a cardiac event monitor which can be worn for a month or more can be used. When used to study the heart, much like standard electrocardiography, the Holter monitor records electrical signals from the heart via a series of electrodes attached to the chest. Electrodes are placed over bones to minimize artifacts from muscular activity. The number and position of electrodes varies by model, but most Holter monitors employ between three and eight. These e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Arrhythmia
Arrhythmias, also known as cardiac arrhythmias, are irregularities in the cardiac cycle, heartbeat, including when it is too fast or too slow. Essentially, this is anything but normal sinus rhythm. A resting heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia, and a resting heart rate that is too slow – below 60 beats per minute – is called bradycardia. Some types of arrhythmias have no symptoms. Symptoms, when present, may include palpitations or feeling a pause between heartbeats. In more serious cases, there may be presyncope, lightheadedness, Syncope (medicine), passing out, shortness of breath, chest pain, or decreased level of consciousness. While most cases of arrhythmia are not serious, some predispose a person to complications such as stroke or heart failure. Others may result in cardiac arrest, sudden death. Arrhythmias are often categorized into four groups: premature heart beat, extra beats, supraventricular tachycard ...

Philips
Koninklijke Philips N.V. (), simply branded Philips, is a Dutch multinational health technology company that was founded in Eindhoven in 1891. Since 1997, its world headquarters have been situated in Amsterdam, though the Benelux headquarters is still in Eindhoven. The company gained its royal honorary title in 1998. Philips was founded by Gerard Philips and his father Frederik, with their first products being light bulbs. Through the 20th century, it grew into one of the world's largest electronics conglomerates, with global market dominance in products ranging from kitchen appliances and electric shavers to light bulbs, televisions, cassettes, and compact discs (both of which were invented by Philips). At one point, it played a dominant role in the entertainment industry (through PolyGram). However, intense competition from primarily East Asian competitors throughout the 1990s and 2000s led to a period of downsizing, including the divestment of its lighting and c ...

Physio-Control
Physio-Control was founded in 1955 by Dr. Karl William Edmark as a pioneering company in the field of portable defibrillation. Physio-Control manufactures emergency defibrillation and automated CPR equipment. The company was most recently acquired in 2016 by Stryker Corporation and is now part of Stryker's Emergency Care division. History In 1955, Dr. Karl William Edmark created The Physio-Control Co. to sell his first Patient Monitor, which simply triggered a light whenever a patient's heart beat, and set off an alarm when a heartbeat is no longer detected. His device was patented as a "Heartbeat Indicator". After moving to Seattle, he developed the first DC Defibrillator. Medical defibrillators at the time used Alternating current which caused patients to spasm violently because of the high voltage. The DC defibrillator allowed surgeons to administer a more-controlled, low-voltage shock that restored the heartbeat without causing additional trauma. In 1968, Physio-Control ...

Lifepak
Lifepak (stylized LIFEPAK) is a series of vital signs monitors and external cardiac defibrillators produced by medical technology company Physio-Control. Lifepak defibrillators are manufactured and distributed from the company headquarters in Redmond, Washington. History Physio-Control publicly demonstrated its first Lifepak branded defibrillator, Lifepak 33, in November 1968 and began commercial sale of the unit the next year in 1969. The Lifepak 33 was the lightest defibrillator available at launch, weighing 34 pounds. The defibrillator was referred to by media as a "90-day wonder" due to the entirety of its development occurring within a 90-day period. Despite being the companies first "LIFEPAK" branded defibrillator, it was named the Lifepak 33 due to the companies target weight of 33 pounds for the defibrillator. In 1971, the Lifepak 911 was released with 12-lead ECG monitoring capability, with the Lifepak 2 being released the following year. The Lifepak 2 was designed spe ...

Cath Lab
A catheterization laboratory, commonly referred to as a cath lab, is an examination room in a hospital or clinic with diagnostic imaging equipment used to visualize the arteries of the heart and the chambers of the heart and treat any stenosis or abnormality found. Equipment Most catheterization laboratories are "single plane" facilities, those that have a single X-ray generator source and an X-ray image intensifier for fluoroscopic imaging. Older cath labs used cine film to record the information obtained, but since 2000, most new facilities are digital. The latest digital cath labs are biplane (have two X-ray sources) and use flat panel detectors. Staff Cardiac catheterization laboratories are usually staffed by a multidisciplinary team. This may include a medical practitioner (normally either a consultant cardiologist or radiologist), cardiac physiologist, radiographer and nurse. Medical practitioner (interventional cardiologist/electrophysiologist) The consultant cardio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Methemoglobin
Methemoglobin (British: methaemoglobin, shortened MetHb) (pronounced "met-hemoglobin") is a hemoglobin ''in the form of metalloprotein'', in which the iron in the heme group is in the Fe3+ (ferric) state, not the Fe2+ (ferrous) of normal hemoglobin. Sometimes, it is also referred to as ferrihemoglobin. Methemoglobin cannot bind oxygen, which means it cannot carry oxygen to tissues. It is bluish chocolate-brown in color. In human blood a trace amount of methemoglobin is normally produced spontaneously, but when present in excess the blood becomes abnormally dark bluish brown. The NADH-dependent enzyme methemoglobin reductase (diaphorase, a type of diaphorase) is responsible for converting methemoglobin back to hemoglobin. Normally one to two percent of a person's hemoglobin is methemoglobin; a higher percentage than this can be genetic or caused by exposure to various chemicals and depending on the level can cause health problems known as methemoglobinemia. A higher level of methemog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Carbon Monoxide
Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest oxocarbon, carbon oxide. In coordination complexes, the carbon monoxide ligand is called ''metal carbonyl, carbonyl''. It is a key ingredient in many processes in industrial chemistry. The most common source of carbon monoxide is the partial combustion of carbon-containing compounds. Numerous environmental and biological sources generate carbon monoxide. In industry, carbon monoxide is important in the production of many compounds, including drugs, fragrances, and fuels. Indoors CO is one of the most acutely toxic contaminants affecting indoor air quality. CO may be emitted from tobacco smoke and generated from malfunctioning fuel-burning stoves (wood, kerosene, natural gas, propane) and fuel-burning heating systems (wood, oil, n ...

Emergency Medicine
Emergency medicine is the medical specialty concerned with the care of illnesses or injuries requiring immediate medical attention. Emergency physicians (or "ER doctors") specialize in providing care for unscheduled and undifferentiated patients of all ages. As frontline providers, in coordination with emergency medical services, they are responsible for initiating resuscitation, stabilization, and early interventions during the acute phase of a medical condition. Emergency physicians generally practice in hospital emergency departments, pre-hospital settings via emergency medical services, and intensive care units. Still, they may also work in primary care settings such as urgent care clinics. Sub-specialties of emergency medicine include disaster medicine, medical toxicology, point-of-care ultrasonography, critical care medicine, emergency medical services, hyperbaric medicine, sports medicine, palliative care, or aerospace medicine. Various models for emerg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Vital Sign
Vital signs (also known as vitals) are a group of the four to six most crucial medical signs that indicate the status of the body's vital (life-sustaining) functions. These measurements are taken to help assess the general physical health of a person, give clues to possible diseases, and show progress toward recovery. The normal ranges for a person's vital signs vary with age, weight, sex, and overall health. There are four primary vital signs: body temperature, blood pressure, pulse (heart rate), and breathing rate (respiratory rate), often notated as BT, BP, HR, and RR. However, depending on the clinical setting, the vital signs may include other measurements called the "fifth vital sign" or "sixth vital sign." Early warning scores have been proposed that combine the individual values of vital signs into a single score. This was done in recognition that deteriorating vital signs often precede cardiac arrest and/or admission to the intensive care unit. Used appropriately, a ...

Paramedic
A paramedic is a healthcare professional trained in the medical model, whose main role has historically been to respond to emergency calls for medical help outside of a hospital. Paramedics work as part of the emergency medical services (EMS), most often in ambulances. They also have roles in emergency medicine, primary care, transfer medicine and remote/offshore medicine. The scope of practice of a paramedic varies between countries, but generally includes autonomous decision making around the emergency care of patients. Not all ambulance personnel are paramedics, although the term is sometimes used informally to refer to any ambulance personnel. In some English-speaking countries, there is an official distinction between paramedics and emergency medical technicians (or emergency care assistants), in which paramedics have additional educational requirements and scope of practice. Functions and duties The paramedic role is closely related to other healthcare positions, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Emergency Medical Services
Emergency medical services (EMS), also known as ambulance services, pre-hospital care or paramedic services, are emergency services that provide urgent pre-hospital treatment and stabilisation for serious illness and injuries and transport to definitive care. They may also be known as a first aid squad, FAST squad, emergency squad, ambulance squad, ambulance corps, life squad or by other acronym, initialisms such as EMAS or EMARS. In most places, EMS can be summoned by members of the public (as well as medical facilities, other emergency services, businesses and authorities) via an emergency telephone number (such as 911 in the United States) which puts them in contact with a dispatching centre, which will then dispatch suitable resources for the call. Ambulances are the primary vehicles for delivering EMS, though Nontransporting EMS vehicle, squad cars, Motorcycle ambulance, motorcycles, Air medical services, aircraft, Water ambulance, boats, Firefighting apparatus, fire appara ...
