GE Healthcare is rolling out a set of wireless, portable sensors designed to be worn by patients during their hospital stay, making it easier for clinicians to keep track of their vital signs without routine check-ins.

The goal is to help keep a closer eye on inpatients and people recovering from surgery—while allowing them to stretch their legs and interact with visitors, without being confined to a hospital bed—and also alert healthcare providers to any early signs of deterioration that may require a move to intensive care.

The Portrait Mobile system includes a waterproof, smartphone-like mobile monitor, which collects information from wearable sensor patches that capture the patient’s breathing rate, pulse and oxygen saturation.
