“…The technical responsibility regarding medical gas equipment in hospitals lies both in the maintenance and in the hospital pharmacy departments [40]. It should be noted that safe medical gas installations are absolutely critical, since any failure might result in a high clinic risk episode for patients [41]. For this reason, leaky gas valves should be replaced and frequent maintenance inspections on medical gas facilities should also occur [42].…”

Analytical Determination of Medical Gases Consumption and Their Impact on Hospital Sustainability

Abstract:Medical gases are known to show a great environmental impact and also to consume relevant resources in terms of hospital management. The present work reports on a study performed between 2008 and 2016 in a target set of 12 Spanish hospitals with floor area and number of beds ranging 2314-23,300 m 2 and 20-194, respectively, for which the average annual consumption rates of oxygen, nitrogen, medicinal air, carbon dioxide and nitrogen protoxide were analysed. The annual consumption of medical gases in a hospital was proved to be correlated with the number of hospital discharges, the number of surgeries, the number of emergency interventions, the number of hospitalisations, the number of hospital beds, the useful floor area of the building and the number of workers. In particular, the annual consumption per hospital bed was computed as 350 m 3 for oxygen, 325 m 3 for medicinal air, 9 m 3 for nitrogen protoxide and 3 m 3 for carbon dioxide. It is shown that healthcare activity appears as an adequate variable to quantify and to monitor medical gases consumption in hospitals, to assess the size of their facilities as well as to optimise maintenance management.

Anaesthetists' management of oxygen pipeline failure: room for improvement*

et al. 2007

SummaryOxygen pipeline failure is a rare but potentially catastrophic event which can affect the care of patients throughout an entire hospital. Anaesthetists play a critical role in maintaining patient safety, and should be prepared to support an institution-wide emergency response if oxygen failure occurs. We tested the preparedness for this through observation of 20 specialist anaesthetists to a standardised simulator scenario of central oxygen supply failure. Responses were documented using multiple approaches to ensure accuracy. All anaesthetists demonstrated safe immediate patient care, but we observed a number of deviations from optimal management, including failure to conserve oxygen supplies and, following restoration of gas supplies, failure to test the composition of the gas supplied from the repaired pipelines. This has implications for patient care at both individual and hospital level. Our results indicate a gap in anaesthesia training which should be addressed, in conjunction with planning for effective hospital-wide responses to the event of critical resource failure.

“…These cylinders are not filled completely, but only up to a filling ratio (weight of gas in a cylinder/weight of water that cylinder can hold at 60 ° F). [3] The filling ratio of oxygen and nitrous oxide is 0.75, but 0.67 in the tropics. The contents of these cylinders can be accurately measured by weighing the cylinders (1.87 g/L of gas) rather than by pressure gauge.…”

“…In every country there are a series of regulations and standards for manufacture and the use of medical cylinders. While regulatory measures are designed to ensure safety in the manufacture and distribution of medical gases, sporadic accidents do occur[3] which have the potential to cause injury to patients, doctors or paramedic staff. Therefore, safety should be the highest priority.…”

Invention of oxygen cylinder was one of the most important developments in the field of medical practice. Oxygen and other gases were compressed and stored at high pressure in seamless containers constructed from hand-forged steel in1880. Materials technology has continued to evolve and now medical gas cylinders are generally made of steel alloys or aluminum. The filling pressure as well as capacity has increased considerably while at the same time the weight of cylinders has reduced. Today oxygen cylinder of equivalent size holds a third more oxygen but weighs about 20 kg less. The cylinders are of varying sizes and are color coded. They are tested at regular intervals by the manufacturer using hydraulic, impact, and tensile tests. The top end of the cylinder is fitted with a valve with a variety of number and markings stamped on it. Common valve types include: Pin index valve, bull nose, hand wheel and integral valve. The type of valve varies with cylinder size. Small cylinders have a pin index valve while large have a bull nose type. Safety features in the cylinder are: Color coding, pin index, pressure relief device, Bodok seal, and label attached etc., Safety rules and guidelines must be followed during storage, installation and use of cylinders to ensure safety of patients, hospital personnel and the environment.
