Scavenger System
{{Unreferenced, date=March 2009 A scavenger system is a medical device used in hospitals. It is used to gather gas or aerosolized medication after it is exhaled from the patient or left the area of the patient. Often used to collect anesthesia, it can also be used to collect any type of gas or aerosolized medicine that is intended only for the patient and should not be breathed in by any other medical personnel. In the Operating Room the Anaesthetic Gas Scavenging System collects and removes waste gases from the patient breathing circuit and the patient ventilation circuit. In most jurisdictions, there is a legal requirement to scavenge waste gases to maintain the level of waste gases in the Operating Room below the legally acceptable limit. For example, in the UK the limits are typically 100ppm for nitrous oxide Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas, nitrous, or nos, is a chemical compound, an oxide of nitrogen with the ...

Medical Device
A medical device is any device intended to be used for medical purposes. Significant potential for hazards are inherent when using a device for medical purposes and thus medical devices must be proved safe and effective with reasonable assurance before regulating governments allow marketing of the device in their country. As a general rule, as the associated risk of the device increases the amount of testing required to establish safety and efficacy also increases. Further, as associated risk increases the potential benefit to the patient must also increase. Discovery of what would be considered a medical device by modern standards dates as far back as c. 7000 BC in Baluchistan where Neolithic dentists used flint-tipped drills and bowstrings. Study of archeology and Roman medical literature also indicate that many types of medical devices were in widespread use during the time of ancient Rome. In the United States it wasn't until the Federal Food, Drug, and Cosmetic Act (F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerosol
An aerosol is a suspension (chemistry), suspension of fine solid particles or liquid Drop (liquid), droplets in air or another gas. Aerosols can be natural or Human impact on the environment, anthropogenic. Examples of natural aerosols are fog or mist, dust, forest exudates, and geyser steam. Examples of anthropogenic aerosols include particulate air pollutants, mist from the discharge at Hydroelectric dam, hydroelectric dams, Irrigation, irrigation mist, Perfume, perfume from atomizers, smoke, steam from a kettle, Pesticide, sprayed pesticides, and medical treatments for respiratory illnesses. When a person inhales the contents of a vape pen or e-cigarette, they are inhaling an Human impact on the environment, anthropogenic aerosol. The liquid or solid particles in an aerosol have diameters typically less than micrometre, 1 μm (larger particles with a significant settling speed make the mixture a Suspension (chemistry), suspension, but the distinction is not clear-cut) ...

Anesthesia
Anesthesia is a state of controlled, temporary loss of sensation or awareness that is induced for medical or veterinary purposes. It may include some or all of analgesia (relief from or prevention of pain), paralysis (muscle relaxation), amnesia (loss of memory), and unconsciousness. An individual under the effects of anesthetic drugs is referred to as being anesthetized. Anesthesia enables the painless performance of procedures that would otherwise cause severe or intolerable pain in a non-anesthetized individual, or would otherwise be technically unfeasible. Three broad categories of anesthesia exist: * General anesthesia suppresses central nervous system activity and results in unconsciousness and total lack of sensation, using either injected or inhaled drugs. * Sedation suppresses the central nervous system to a lesser degree, inhibiting both anxiety and creation of long-term memories without resulting in unconsciousness. * Regional and local anesthesia, which blo ...

Nitrous Oxide
Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas, nitrous, or nos, is a chemical compound, an oxide of nitrogen with the formula . At room temperature, it is a colourless non-flammable gas, and has a slightly sweet scent and taste. At elevated temperatures, nitrous oxide is a powerful oxidiser similar to molecular oxygen. Nitrous oxide has significant medical uses, especially in surgery and dentistry, for its anaesthetic and pain-reducing effects. Its colloquial name, "laughing gas", coined by Humphry Davy, is due to the euphoric effects upon inhaling it, a property that has led to its recreational use as a dissociative anaesthetic. It is on the World Health Organization's List of Essential Medicines. It is also used as an oxidiser in rocket propellants, and in motor racing to increase the power output of engines. Nitrous oxide's atmospheric concentration reached 333 parts per billion (ppb) in 2020, increasing at a rate of abo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Gas Supply
Medical gas supply systems in hospitals and other healthcare facilities are utilized to supply specialized gases and gas mixtures to various parts of the facility. Products handled by such systems typically include: *Oxygen * Medical air *Nitrous oxide *Nitrogen *Carbon dioxide * Medical vacuum * Waste anaesthetic gas disposal (US) or anaesthetic gas scavenging system (ISO) Source equipment systems are generally required to be monitored by alarm systems at the point of supply for abnormal (high or low) gas pressure in areas such as general ward, operating theatres, intensive care units, recovery rooms, or major treatment rooms. Equipment is connected to the medical gas pipeline system via station outlets (US) or terminal units (ISO). Medical gas systems are commonly color coded to identify their contents, but as coding systems and requirements (such as those for bottled gas) vary by jurisdiction, the text or labeling is the most reliable guide to the contents. Emergency shut- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Station Outlet
Station Outlets (US) or Terminal Units (ISO, CSA) consist of an outlet port with color-coded faceplate attached to a medical gas supply line, and primary and secondary check valves which open and close automatically upon use and disengagement from the system.CSA Z7396.1-17 - Medical gas pipeline systems - Part 1: Pipelines for medical gases, medical vacuum, medical support gases, and anaesthetic gas scavenging systems In most jurisdictions, Station Outlets are required to be equipped with safety systems that prevent ''cross-connection'' errors, such as connecting a Medical air flowmeter to an Oxygen port. Hospitals mainly use ''DISS'' connections, though a wide variety of '' quick-connect'' adapters, based on male strikers and female outlet ports, are still in use today. These latter types are easier to connect, but are more prone to leaks and failure.
