Critical Care Air Transport Team
The Critical Care Air Transport Team (CCATT) concept dates from 1988, when Col. P.K. Carlton and Maj. J. Chris Farmer originated the development of this program while stationed at U.S. Air Force Hospital Scott, Scott Air Force Base, Illinois. Dr. Carlton was the Hospital Commander, and Dr. Farmer was a staff intensivist. The program was developed because of an inability to transport and care for a patient who became critically ill during a trans-Atlantic air evac mission in a C-141. They envisioned a highly portable intensive care unit (ICU) with sophisticated capabilities, carried in backpacks, that would match on-the-ground ICU functionality. This concept was further developed at Wilford Hall Medical Center in 1991–1992, when Dr. Carlton served as the 59th Medical Wing commander and the AETC/SG and Dr. Farmer, joined by Major Jay Johannigman, were intensivist colleagues at Wilford Hall. Together, they developed the first written concept of operations for this team, a table of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scott Air Force Base
Scott Air Force Base is a United States Air Force base in St. Clair County, Illinois, near Belleville and O'Fallon, east-southeast of downtown St. Louis. Scott Field was one of thirty-two Air Service training camps established after the United States entered World War I in April 1917. It is headquarters of Air Mobility Command (AMC), and is also the headquarters of the U.S. Transportation Command, a Unified Combatant Command that coordinates transportation across all the services. The base is operated by the 375th Air Mobility Wing (375 AMW) and is also home to the Air Force Reserve Command's 932d Airlift Wing (932 AW) and the Illinois Air National Guard's 126th Air Refueling Wing (126 ARW), the latter two units being operationally gained by AMC. The base currently employs 13,000 people, 5,100 civilians with 5,500 active-duty Air Force, and an additional 2,400 Air National Guard and Reserve personnel. It was announced in June 2014 that two new cybersecurity squadrons wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intensive Care Medicine
Intensive care medicine, also called critical care medicine, is a medical specialty that deals with seriously or critically ill patients who have, are at risk of, or are recovering from conditions that may be life-threatening. It includes providing life support, invasive monitoring techniques, resuscitation, and end-of-life care. Doctors in this specialty are often called intensive care physicians, critical care physicians or intensivists. Intensive care relies on multidisciplinary teams composed of many different health professionals. Such teams often include doctors, nurses, physical therapists, respiratory therapists, and pharmacists, among others. They usually work together in intensive care units (ICUs) within a hospital. Scope Patients are admitted to the intensive care unit if their medical needs are greater than what the general hospital ward can provide. Indications for the ICU include blood pressure support for cardiovascular instability ( hypertension/hypote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Medical Services In The United States
In the United States, emergency medical services (EMS) provide out-of-hospital acute medical care and/or transport to definitive care for those in need. They are regulated at the most basic level by the National Highway Traffic Safety Administration, which sets the minimum standards that all states' EMS providers must meet, and regulated more strictly by individual state governments, which often require higher standards from the services they oversee. Wide differences in population density, topography, and other conditions can call for different types of EMS systems; consequently, there is often significant variation between the Emergency Medical Services provided in one state and those provided in another. Organization and funding Land ambulance EMS delivery in the US can be based on various models. While most services are, to some degree, publicly funded, the factor which often differentiates services is the manner in which they are operated. EMS systems may be directly ope ...

Aviation Medicine
Aviation medicine, also called flight medicine or aerospace medicine, is a preventive or occupational medicine in which the patients/subjects are pilots, aircrews, or astronauts. The specialty strives to treat or prevent conditions to which aircrews are particularly susceptible, applies medical knowledge to the human factors in aviation and is thus a critical component of aviation safety. A military practitioner of aviation medicine may be called a flight surgeon and a civilian practitioner is an aviation medical examiner. One of the biggest differences between the military and civilian flight doctors is the military flight surgeon's requirement to log flight hours. Overview Broadly defined, this subdiscipline endeavors to discover and prevent various adverse physiological responses to hostile biologic and physical stresses encountered in the aerospace environment. Problems range from life support measures for astronauts to recognizing an ear block in an infant traveling on an a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemodynamic
Hemodynamics or haemodynamics are the dynamics of blood flow. The circulatory system is controlled by homeostatic mechanisms of autoregulation, just as hydraulic circuits are controlled by control systems. The hemodynamic response continuously monitors and adjusts to conditions in the body and its environment. Hemodynamics explains the physical laws that govern the flow of blood in the blood vessels. Blood flow ensures the transportation of nutrients, hormones, metabolic waste products, oxygen, and carbon dioxide throughout the body to maintain cell-level metabolism, the regulation of the pH, osmotic pressure and temperature of the whole body, and the protection from microbial and mechanical harm. Blood is a non-Newtonian fluid, and is most efficiently studied using rheology rather than hydrodynamics. Because blood vessels are not rigid tubes, classic hydrodynamics and fluids mechanics based on the use of classical viscometers are not capable of explaining haemodynamics. The st ...

Multiple Organ Failure
Multiple organ dysfunction syndrome (MODS) is altered organ function in an acutely ill patient requiring medical intervention to achieve homeostasis. Although Irwin and Rippe cautioned in 2005 that the use of "multiple organ failure" or "multisystem organ failure" should be avoided, both Harrison's (2015) and Cecil's (2012) medical textbooks still use the terms "multi-organ failure" and "multiple organ failure" in several chapters and do not use "multiple organ dysfunction syndrome" at all. There are different stages of organ dysfunction for certain different organs, both in acute and in chronic onset, whether or not there are one or more organs affected. Each stage of dysfunction (whether it be the heart, lung, liver, or kidney) has defined parameters, in terms of laboratory values based on blood and other tests, as to what it is (each of these organs' levels of failure is divided into stage I, II, III, IV, and V). The word "failure" is commonly used to refer to the later stages ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Respiratory Failure
Respiratory failure results from inadequate gas exchange by the respiratory system, meaning that the arterial oxygen, carbon dioxide, or both cannot be kept at normal levels. A drop in the oxygen carried in the blood is known as hypoxemia; a rise in arterial carbon dioxide levels is called hypercapnia. Respiratory failure is classified as either Type 1 or Type 2, based on whether there is a high carbon dioxide level, and can be acute or chronic. In clinical trials, the definition of respiratory failure usually includes increased respiratory rate, abnormal blood gases (hypoxemia, hypercapnia, or both), and evidence of increased work of breathing. Respiratory failure causes an altered mental status due to ischemia in the brain. The typical partial pressure reference values are oxygen Pa more than 80 mmHg (11 kPa) and carbon dioxide Pa less than 45 mmHg (6.0 kPa). Cause Several types of conditions can potentially result in respiratory failure: * Conditions that reduce the fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burn
A burn is an injury to skin, or other tissues, caused by heat, cold, electricity, chemicals, friction, or ultraviolet radiation (like sunburn). Most burns are due to heat from hot liquids (called scalding), solids, or fire. Burns occur mainly in the home or the workplace. In the home, risks are associated with domestic kitchens, including stoves, flames, and hot liquids. In the workplace, risks are associated with fire and chemical and electric burns. Alcoholism and smoking are other risk factors. Burns can also occur as a result of self-harm or violence between people (assault). Burns that affect only the superficial skin layers are known as superficial or first-degree burns. They appear red without blisters and pain typically lasts around three days. When the injury extends into some of the underlying skin layer, it is a partial-thickness or second-degree burn. Blisters are frequently present and they are often very painful. Healing can require up to eight weeks and scarri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shock (circulatory)
Shock is the state of insufficient blood flow to the tissues of the body as a result of problems with the circulatory system. Initial symptoms of shock may include weakness, fast heart rate, fast breathing, sweating, anxiety, and increased thirst. This may be followed by confusion, unconsciousness, or cardiac arrest, as complications worsen. Shock is divided into four main types based on the underlying cause: low volume, cardiogenic, obstructive, and distributive shock. Low volume shock, also known as hypovolemic shock, may be from bleeding, diarrhea, or vomiting. Cardiogenic shock may be due to a heart attack or cardiac contusion. Obstructive shock may be due to cardiac tamponade or a tension pneumothorax. Distributive shock may be due to sepsis, anaphylaxis, injury to the upper spinal cord, or certain overdoses. The diagnosis is generally based on a combination of symptoms, physical examination, and laboratory tests. A decreased pulse pressure (systolic blood pressure m ...

Physical Trauma
An injury is any physiological damage to living tissue caused by immediate physical stress. An injury can occur intentionally or unintentionally and may be caused by blunt trauma, penetrating trauma, burning, toxic exposure, asphyxiation, or overexertion. Injuries can occur in any part of the body, and different symptoms are associated with different injuries. Treatment of a major injury is typically carried out by a health professional and varies greatly depending on the nature of the injury. Traffic collisions are the most common cause of accidental injury and injury-related death among humans. Injuries are distinct from chronic conditions, psychological trauma, infections, or medical procedures, though injury can be a contributing factor to any of these. Several major health organizations have established systems for the classification and description of human injuries. Occurrence Injuries may be intentional or unintentional. Intentional injuries may be acts o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airframe
The mechanical structure of an aircraft is known as the airframe. This structure is typically considered to include the fuselage, undercarriage, empennage and wings, and excludes the propulsion system. Airframe design is a field of aerospace engineering that combines aerodynamics, materials technology and manufacturing methods with a focus on weight, strength and aerodynamic drag, as well as reliability and cost.Michael C. Y. Niu (1988). ''Airframe Structural Design''. Conmilit Press LTD. History Modern airframe history began in the United States when a 1903 wood biplane made by Orville and Wilbur Wright showed the potential of fixed-wing designs. In 1912 the Deperdussin Monocoque pioneered the light, strong and streamlined monocoque fuselage formed of thin plywood layers over a circular frame, achieving . First World War Many early developments were spurred by military needs during World War I. Well known aircraft from that era include the Dutch designer Anth ...

Respiratory
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history. In land animals the respiratory surface is internalized as linings of the lungs. Gas exchange in the lungs occurs in millions of small air sacs; in mammals and reptiles these are called alveoli, and in birds they are known as atria. These microscopic air sacs have a very rich blood supply, thus bringing the air into close contact with the blood. These air sacs communicate with the external environment via a system of airways, or hollow tubes, of which the largest is the trachea, which branches in the middle of the chest into the two main bronchi. These enter the lungs where they branch into progressively narrower secondary and terti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
