Measurement solution for medical workplace monitoring - Health and Safety - Health and Safety Monitoring and Testing
In taking a responsible stance on the exposure of workers to any potential hazardous gases, there is a need for workplaces using anaesthetic gases, such as hospital operating rooms or research laboratories, to control the level of waste anaesthetic gas in the ambient air. Anaesthesia machines, ventilators, breathing systems and waste gas scavenging systems will all contribute to te background level of he anaesthetic gases that are present in the environment within a facility, whether those machines are in a good state of repair or not. Recovery rooms can become polluted, for example from gas exhaled by the patient, and clean-up from any spills can remain in the background air for long periods.
Waste gas disposal can be carried out with a well-fonctioning non-circulating room ventilation system. However, the monitoring of trace gas levels of anaesthetic gases in the workplace allows building management systems to access and control the waste gas control system and provide workers with a safe and healthy working environment; plus that all important confidence that all is well.
Protea's latest FTIR multigas analyser, atmosFIR, uses full spectrum infrared analysis and is able to measure all anaesthetic gases simultaneously. The analyser modue with a room temperature operated DTGS detector that is ideally suited to measuring all the halogenated and other compounds present such as Halothane, Isoflurane, Sevoflurane and Desflurane.
The key to this product is the combination of a new generation FTIR with Protea's advanced chemometric algorithm with the FTIR software which separates and quantifies each gas response individually and accurately. Protea's analysis method is real time, seamless and provides specific gas concentrations on screen, with configurable alarms to give appropriate status levels or warning. The system is also able to indicate that individual concentrations are being measured correctly and conversely if there is a problem. With an internal measurement cell optimise for workplace exposure limit measuremnts of anaesthetic gases, the sstem has a low level of detection.
The atmosFIR system for workplace exposure monitoring is not limited to a single point of measurement. By incorporating a multi-stream switching system, the analyser can be programmed to a sample across a number of different measurenet points in a sequence. FOr example, it can measure at a number of of locations within an operating theatre - such as the gas delivery equipment and at the location of waste gas removal. The controlling programme can be sequenced to allow some measurement points to be sampled for longer or shorter than others. By using easy to intall PTFE ample lines and a suitable sample flow rate, each measurement point can generate an acuurate result in 30 seconds or less.
