Why piCObaby™?

The piCObabyTM offers an unprecedented view of the internal effects of smoking by using the traffic light results system for both the mum-to-be and the baby.

Why is it important?

The piCObabyTM CO monitor is a valuable tool for pregnant smokers to visualise the effects that smoking is having on them and their child.

Smoking in Pregnancy Software

Smoking in Pregnancy is a software specifically designed to help mums-to-be quit smoking. Compatible with the Micro+™ and piCObaby™ Smokerlyzer®. Once the monitor is connected to the computer, it uses a traffic-light colour system and shows the live CO reading of the expectant mother as well as the %FCOHb conversion. As seen on BBC’s Misbehaving Mums, the Smoking in Pregnancy software is a valuable tool to help expectant mothers quit smoking.

Benefits for the user

The monitor provides instant results shown in exact ppm, %COHb and %FCOHb, which makes recording and interpreting patient’s results quick and easy.

With added SteriTouch® antimicrobial additives to ensure optimum infection control.

There is the familiar green, amber and red traffic light system, making CO levels instantly identifiable to patients.

D-pieces are used in conjunction with the monitor to filter out 99.9% of airborne bacteria and single-use SteriBreath™ mouthpieces for excellent, low cost infection control.

Five-year warranty for absolute peace of mind.
