The Micro⁺ Smokerlyzer is Bedfont’s latest and most advanced monitor. Long regarded as the benchmark for breath CO monitors used in smoking cessation programmes and research, the Micro⁺ has been upgraded to provide even more functions.

Despite the dangers of smoking during pregnancy being well documented, many women need the support and advice of a health professional in order to give up. A percentage of oxygen carried by a smoker’s blood will be replaced by CO (COHb), causing breathlessness and strain on the heart. Less oxygen than normal will be supplied to the unborn child of a pregnant smoker, leading to increased risk of underdevelopment, low birthweight and health complications after birth. The Micro+ has the ability to monitor the mother’s CO levels in COppm (alveolar CO levels in parts per million) and %COHb as well as the levels passed on to the foetus (%FCOHb). The monitor’s colour touch-screen means that the user can switch between readings for the mother and foetus with a single touch, visually illustrating the risk to the patient and her child.

As well as having the ability to display %FCOHb, the Micro⁺ can be used effectively in stop smoking programmes for a range of other smokers and situations. A motivational traffic light system of green, amber and red displays smoking status in relation to ppm levels. These levels can be switched between adult and adolescent settings to suit hard to motivate or low level smokers. Custom levels can also be set through COdata+ software, useful for example when readings are taking during the morning when the patient will not have had their normal quota of cigarettes. Patient data can be recorded on the instrument itself, including name, time of test and result, and displayed in a table or graph. The Micro+ measures up to 250ppm, enabling the monitor to also screen for CO poisoning. Further medical advice should be sought if unexpectedly high CO readings are obtained as part of routine CO monitoring.

Bedfont’s Micro Smokerlyzer^® has been used within clinical studies for over 20 years. The Micro⁺ is fitted with a superior sensor and anti-humidity filter and has a low hydrogen cross-interference, making it ideal for research programmes.

Calibration

The Micro⁺ requires a calibration check at least once every six months with Bedfont's 50ppm CO in air calibration gas. A reminder that calibration is due will be displayed on the instrument’s start-up screen every 24 weeks. No specialist technical knowledge or skills are required, making it easy to calibrate with our Calibration Kit. We can also supply replacement calibration gas in lightweight disposable cylinders.

A range of annual service packages are also available.

Consumables & Accessories

Cardboard mouthpieces are connected to the Micro⁺ via a D-piece. A one-way valve prevents air being drawn back form the monitor. This system further reduces the risks of cross infection and protects the instrument from contamination. The breath then passes through an infection control filter, proven to remove and trap >99.9% of airborne bacteria1. This system further reduces the risks of cross infection and protects the instrument from contamination. Bedfont recommend that D-pieces are changed once every month or if visibly soiled – a prompt will be displayed on the instrument every 28 days.

Bedfont also supply an instrument cleansing wipe specifically developed for cleaning the surface of the monitors. Each wipe contains 1% Cetrimide, a powerful antimicrobial detergent. The wipes can also be used by patients to clean their hands before handling the instruments in areas without hand washing facilities. Alcohol, or cleaning agents containing alcohol, should never be used as they may adversely affect the sensor within the instrument.

COdata^+™ is a software programme for Microsoft Windows, for use with the piCO⁺ and Micro⁺ Smokerlyzers^®.12

When connected to the Micro⁺ the software allows users to create custom ppm settings. Test results stored on the instrument can be downloaded into COdata^+™, which provides an instant report of the patient's results. The report includes a specific interpretation of the patient's smoking habit and personal dependence on nicotine. This can be printed out and kept by the patient for their own records.
