Product Description

Biosensor

The Philips wearable biosensor-G5 solution is a patient heart rate sensing system comprising a Philips wearable biosensor-G5 and a G5 software application. It gathers, stores, and displays a patient's heart rate. The biosensor G5 connects with the G5 application, allowing clinicians to review and export patient heart rate data. Heart rate measurements are sent to a compatible device using a USB cable for offline review and analysis.

The Philips wearable biosensor-G5 is a wireless, single-use, single-location chest-worn device that acquires surface electrical waveforms related to cardiac excitations and measures beat-to-beat intervals. The biosensor calculates patient heart rate based on a combination of the patient's single-vector ECG and their motion data. The biosensor has a wear life of two days, after which it turns off automatically.

General Warnings and Precautions

Warnings

• Do not use the biosensor during MRI procedures; it is MRI unsafe.
• Do not use the biosensor during X-ray as it will obstruct the view of an X-ray of the chest.
• The biosensor should only be used under direct supervision of a licensed physician or healthcare provider, according to the hospital standard of care.
• Do not use for more than 48 hours. Replace the biosensor if it no longer sticks firmly to the skin. Proper adherence is required to obtain a signal from the body.
• Do not use if the hydrogel is dry. Keep the biosensor in its sealed package and open immediately before use to prevent hydrogel drying.
• The biosensor is for single use only. Do not reuse due to the risk of cross-infection, degradation of adhesive, or electrical performance.
• Do not apply over open wounds, lesions, infected, irritated, scarred, or inflamed areas. Apply only to intact skin.
• Do not apply to patients with a history of known tape or adhesive allergy, as the biosensor contains an adhesive.
• Warning for pacemaker patients: The biosensor can detect pacemaker pulses and may continue to count the pacemaker rate during cardiac arrest or some arrhythmias. Do not rely entirely on the biosensor. Keep pacemaker patients under close surveillance. Refer to the G5 application interface section for details on pacemaker pulse detection capability.
• Warning for pacemaker patients: The biosensor can detect pacemaker pulses. Do not use it for rejecting pace pulses. A 'pace-pulse detected' notification will appear for interrupted measurements, and the heart rate value will not display during a detected pacing event.
• Do not use the biosensor simultaneously with cardiac monitors or cardiac telemetry devices that are in direct contact with the thorax, as this may degrade signal quality or produce erroneous results. This potential interaction has not been evaluated.
• Do not use the device for diagnosis. If a patient's condition does not match the values, take a confirmatory, independent check of vitals (including 12-lead ECG).
• Do not use the device to discern abnormal rhythm patterns or for alarms.
• Do not use the biosensor with high frequency surgical equipment.
• No modification of this equipment is allowed.

Precautions
