Masimo won FDA clearance for its RAS-45 acoustic respiration sensor, used with the rainbow Acoustic Monitoring (RAM), to be used on infants and neonates. Previously, only patients over 22 pounds (10 kilograms) were eligible for RAM sensors, but the new clearance provides an easy way to monitor the rate of breathing in the tiniest patients. This is partially thanks to the sensor’s maximum breathing rate being increased to 120 breaths per minute while maintaining accuracy within +/- 1 breath per minute.
The stick-on sensor has a microphone-like device built in, which can detect respirations while ignoring other sounds. It also lets clinicians to actually listen to the breathing, as though through a stethoscope. In adults, it is placed on the neck, while in small infants and neonates it is placed right on the chest.
The monitor to which the RAS-45 is connected displays the current respiration rate and a waveform showing the recent breathing history, along with data from whatever other sensors the monitor is interfaced with.
