DELTA RM15 Apnoea Monitor

Apnoea detection in infants and neonates

The RM15 is a simple, reliable respiration monitor for apnoea detection in babies and infants up to 18 months old, with no lower age or weight limit.

The device uses a disposable pneumatic sensor for reliability and convenience to detect movement of the infant’s abdominal wall. The monitor works by giving audio and visual alarms if the infant stops breathing for more than a user-selected time. 

Infants at risk of respiratory failure may suffer apnoea unexpectedly and even with the most diligent care such episodes can easily go unnoticed.

Designed with state-of-the-art technology, the RM15 provides robust and effective apnoea monitoring, enabling early detection of the cessation of breathing to ensure appropriate intervention can be commenced immediately.

The RM15 apnoea monitor is lightweight and portable, making it suitable for use in the full range of hospital settings – NICU, maternity, post-natal and paediatric departments – as well as in the community.
