Medical piped gas systems in hospitals, and most other healthcare facilities, are essential for supplying piped oxygen, nitrous oxide, nitrogen, carbon dioxide and medical air to various parts of the hospital. These systems are usually highly monitored by various computerized alarm systems.
Oxygen may be used for patients requiring supplemental oxygen via a mask. Usually accomplished by a large storage system of liquid oxygen at the hospital which is evaporated into a concentrated oxygen supply, pressures are usually around 55 psi. In small medical centers with a low patient capacity, oxygen is usually supplied by multiple standard cylinders.
Nitrous Oxide is supplied to various surgical suites for its anesthetic functions during pre-operative procedures. Delivered to the hospital in standard tanks and supplied through the Medical Gas system. System pressures around 50 psi.
Nitrogen is typically used to power surgical equipment during various procedures. Pressures range around 175 psi to the various locations.
Typically used to inflate or suspend tissues during surgery. System pressures are maintained at about 50 psi. it is also used in laser surgeries.
Medical Air is supplied by a special air compressor to patient care areas using clean outside air. Pressures are maintained around 55 psi.
There are many gas mixtures used for clinical and medical applications. They are often used for patient diagnostics such as lung function testing or blood gas analysis. Test gases are also used to calibrate and maintain medical devices used for the delivery of anaesthetic gases.
Culture growth applications include controlled aerobic or anaerobic incubator atmospheres for biological cell culture or tissue growth. Controlled aerobic conditions are created usign mixtures rich in oxygen and anaerobic conditions are created using mixtures rich in hydrogen or carbon dioxide.
Medical Vacuum in a hospital supports vacuum equipment and evacuation procedures, usually supplied by various vacuum pump systems exhausting to the atmosphere. Continuous vacuum is maintained around 22 inches of mercury.executive
