A medical-grade, wireless device that adheres discreetly to the chest, the Philips Biosensor BX100 measures vital signs, posture and activity while allowing patient mobility. It is designed to work with IntelliVue GuardianSoftware to aid early identification of patient deterioration, driving early intervention.

Small, wireless sensor
Lightweight and comfortable

Lightweight and comfortable

At just 96 mm (3.78 in) long and 61 mm (2.40 in) wide, and weighing only 10 g (0.35 oz), the Philips Biosensor BX100 is unobtrusive and comfortable.1 There are no wires or finger clips, and the biosensor can even be worn in the shower.
Frequent measurements
Data insights drive intervention

Data insights drive intervention

Respiration rate is the earliest predictor of clinical deterioration, often changing hours before other vital signs.2 Frequent monitoring by the Philips Biosensor BX100 can replace visual observation counts, which may be unreliable and inconsistent.3 The combination of respiratory rate and heart rate monitoring assists caregivers in identifying patients at risk for deterioration.
Automatic measurement and recording
Supports effective use of caregivers’ time

Supports effective use of caregivers’ time

Because the Philips Biosensor BX100 frequently and automatically measures, records and transmits vital signs data, it can free time for more effective use of staff resources and may reduce errors caused by manual transcription.
Wi-fi transmission of patient data
Integrates with IntelliVue GuardianSoftware

Integrates with IntelliVue GuardianSoftware

As patients walk about the ward, multi-patient Bluetooth routers capture data from the biosensors and send it to IntelliVue GuardianSoftware via your Wi-Fi network. IntelliVue GuardianSoftware identifies significant deviations in a patient’s vital signs and automatically verifies the accuracy of the trend. It then notifies caregivers of the change, driving early intervention.
Multi-patient bridge supports multiple patients
Routers support up to 16 biosensors

Routers support up to 16 biosensors

As patients move about the ward, data from the biosensors is wirelessly transmitted via a Multi-patient bridge, which consists of ceiling-mounted routers that can accommodate connection with up to 16 biosensors per router. The Multi-patient bridge features a 30 m (100 ft) line-of-sight connectivity.

  • * Biosensor will collect data up to 115 hours and will attempt to transmit stored data for up to 120 hours. Each patient’s experience will be different; actual operational life and data transmission period may be shorter for some patients.
  • **Biosensor will reject pacemaker pulses and accurately compute heart rate when it detects pacemaker pulses with amplitudes = ±2 mV to = ±700 mV and pulse width = 0.1 ms and amplitudes = ±2 mV but ±50 mV and pulse width = 2 ms (with the exclusion of dual-chamber pacing and pace pulses with tails) Biosensor will indicate that data is invalid when it detects pacemaker pulses with amplitudes = ±100 mV but = ±700 mV and pulse width = 2 ms (with the exclusion of dual-chamber pacing and pace pulses with tails) or ineffectively paced QRS complexes. Philips does not claim, verify or validate support for all available pacemakers.
  • ***Posture accuracy depends on biosensor calibration, which occurs automatically after patient has ambulated for at least 15 seconds
  • † Actual range will vary depending on the Bluetooth backend system to which the biosensor is connected.
