|This article is missing information about the origin of the term "crash cart". (March 2013)|
A crash cart or code cart (crash trolley in UK medical jargon) is a set of trays/drawers/shelves on wheels used in hospitals for transportation and dispensing of emergency medication/equipment at site of medical/surgical emergency for life support protocols (ACLS/ALS) to potentially save someone's life.
The contents of a crash cart vary from hospital to hospital, but typically contain the tools and drugs needed to treat a person in or near cardiac arrest. These include but are not limited to:
- Monitor/defibrillators, suction devices, and Bag Valve Masks (BVMs) of different sizes
- Advanced Cardiac Life Support (ACLS) drugs such as epinephrine, atropine, amiodarone, lidocaine, sodium bicarbonate, dopamine, and vasopressin
- First line drugs for treatment of common problems such as: adenosine, dextrose, diazepam or midazolam, epinephrine for IM use, naloxone, nitroglycerin, and others
- Drugs for rapid sequence intubation: Succinylcholine or another paralytic, and a sedative such as etomidate or midazolam; endotracheal tubes and other intubating equipment
- Drugs for peripheral and central venous access
- Pediatric equipment (common pediatric drugs, intubation equipment, etc.)
- Other drugs and equipment as chosen by the facility
Hospitals typically have internal intercom codes used for situations when someone has suffered a cardiac arrest or a similar potentially fatal condition outside of the emergency room or intensive care unit (where such conditions already happen frequently and do not require special announcements). When such codes are given, hospital staff and volunteers are expected to clear the corridors, and to direct visitors to stand aside as the crash cart and a team of physicians and nurses may come through at any moment. (See Code Blue.)
History in the United States
The first cardiac crash cart was created in 1962 at Bethany Medical Center in Kansas City, Kansas, home to the first Cardiac Care Unit in the country. The first crash cart was fabricated by one of the doctor's fathers. It contained an Ambu bag, defibrillator paddles, a bed board and endotracheal tubes.
In the computer industry, the term crash cart is used, by analogy to its original meaning in medicine, to mean a cart that can be connected to a server that is malfunctioning so badly that remote access to it is impossible, the intention being to "resuscitate" the server to the point where remote administration works again. Crash carts most commonly include a keyboard, mouse, and monitor, because most servers in a modern high-density environment don't have user input/output devices.
The phrase, as applied to computing, was coined independently from its usage in a medical context. The term "crash" has long been used to describe computer systems failures which require physical access and placement of a computer monitor, keyboard and other peripherals on a rolling "cart" leads rather obviously to the resulting phrase.
Crash carts are a method of last resort in data centers which employ various forms of out-of-band management. In those cases it is used for equipment which does not support the requisite out-of-band infrastructure (OOBI) features or in cases where the OOBI devices (concentrators, switches, terminal servers, etc.) or services themselves have failed.
The term "crash cart" can also refer to a bootable removable medium containing an operating system and any relevant software used to recover computer equipment (such as a server or PC) from a state of failure. This is done when such recovery is not possible using the computer's existing operating system and software. Crash carts in this sense are historically tape cartridges ("carts") or more recently, external or removable hard drives.
