The Nihon Kohden Vital Sign Telemeters GZ-120P and GZ-130P are intended to monitor and transmit physiological data from a patient to a Nihon Kohden monitor via radiofrequency in the 802.11 band for continuous monitoring. Both GZ-120P and GZ-130P transmit electrocardiogram (ECG) and respiration data, and GZ-130P transmits blood oxygen saturation (SpO2) in addition. The device may generate an audible and/or visible alarm when an arrhythmia exists, when a measured physiological rate falls outside preset limits, or when a technical error is detected. Furthermore, the devices can be configured for use as a temporary simple monitor to display the patient’s vital signs on the device screens and generate alarms without transmitting the data to other Nihon Kohden monitor.
The devices are intended to be used by qualified medical personnel within a medical facility, such as hospital or clinic, on all patient populations including adult, neonate, infant, child, and adolescent subgroups.
Indications for use as stated in the FDA summary.
