As a caregiver, you want to sustain your patient’s mobility and comfort. Cableless transducers can help, without sacrificing essential monitoring. However, traditional cableless technology has limitations, such as mothers with a high BMI[1, 2] or those undergoing epidural procedures. This is where the Avalon beltless maternal and fetal monitoring solution provides an alternative.
