Definitions CAUTION, indicates a potentially hazardous situation, which, if not avoided, may result in minor or moderate injury. It may be used to alert against unsafe practices. It may also be used to indicate the possibility of erroneous data that could result in an incorrect diagnosis (does not apply to all products). IMPORTANT, is used for comments that add value to the step or procedure being performed. Following the IMPORTANT advice adds benefit to the performance of the equipment or to a process. NOTE, is used to call attention to notable information that should be followed during installation, use, or servicing of the equipment. Intended use The GastroCH ECK® Gastrolyzer® is a portable desktop monitor which measures hydrogen (H methane (CH ) and oxygen (O ) levels in expired breath samples in response to appropriate substrates. It is intended to be for multi-patient use on children and adults and used by healthcare professionals primarily in a hospital, or physician’s surgery. The expired breath can be delivered direct to the monitor for immediate analysis via a mouthpiece or a sample can be taken remotely via a breath-bag for subsequent analysis. The GastroCH ECK® Gastrolyzer® will be used by a single patient at a time, but will interface with a PC to allow a multi-patient sampling protocol to be performed. The GastroCH ECK® Gastrolyzer® can be used as an aid to diagnose the following disorders: Carbohydrate breakdown deficiency • Carbohydrate malabsorption • Lactose intolerance • Bacterial overgrowth • Determination of time of passage through gut • Specific diagnosis is not possible with this device; further specific testing would need to be carried out to diagnose a patient’s condition. Introduction and CH are generated in the intestinal lumen by bacterial action on carbohydrates in the small or large intestine. Once the resultant H... -
Page 4: Safety Notes
The GastroCH ECK® Gastrolyzer® also measures O levels in the breath sample in order to correct for any tests that do not achieve an end-tidal breath sample. The end-tidal breath sample is that last portion of expired air and contains the most accurate levels of H and CH . End-tidal breath contains approx. 14-16% O and therefore corrections to the final result can be made if required by applying a correction factor if more than 14% O is recorded in the sample. Operation of the monitor is straightforward. A sampling system enables end-expired breath to be sampled easily and hygienically, using single-use disposable mouthpieces and single-use disposable face masks. Safety notes To avoid electric shock, this equipment must be connected to a mains supply with protective earth- grounding. The operator should not touch the patient whilst in contact with either the computer or the USB connector parts.
