Nanny Baby Respiration Monitor BM-02 continuously checks your baby's breathing and movements to confirm the absence of a possible danger. It triggers an acoustic and visual alarm if breathing stops for longer than 20 seconds or if the rate of breathing is bellow acceptable limit 8 breaths per minute. This allows for Apnea Sudden Infant Death Syndrome and other life threatening conditions to be indicated in time to save the child. The sensor pad, positioned under the mattress, detects the gentle movements of an infant's chest. Nanny Baby Respiration Monitor BM-02 carries complete CE registration as a medical device and complies with 93/42/EC Device Directive. Nanny's ultra-sensitive pad is the largest on the market and it is the only baby monitor that can be upgraded to use two ultra-sensitive sensor pads. It operates on regular AA household batteries for safety and simplicity. This baby monitor is suitable for mattresses up to 14cm and is fully portable. It has low battery life indicator. The Nanny monitor does NOT come with a parent unit - this is so that you stay close to your baby when he/she is sleeping and if the alarm sounds telling you your baby is not breathing you can get to them more quickly. The baby monitor is suitable from newborn.
