BN-RSP2 - BioNomadix 2Ch RSP Pair

Biopac BN-RSP2 / BN-RSP2-T - BioNomadix 2Ch RSP

The Dual RSP BioNomadix amplifier is specifically designed to measure respiratory effort associated with circumferential changes in the thoracic or abdominal regions of the torso. Record one or two channels of data. The transmitter unit can be used either with an MP160/MP150 using a matched receiver unit, or directly with a BioNomadix Logger. The matched pair emulates a "wired" connection from subject to computer, with all the benefits of a fully-wireless recording system.

Biopac BN-RSP2 / BN-RSP2-T - BioNomadix 2Ch RSP

Dual-channel Respiration Wireless Transmitter & Receiver

The Dual RSP BioNomadix amplifier is specifically designed to measure respiratory effort associated with circumferential changes in the thoracic or abdominal regions of the torso. Record one or two channels of data. The transmitter unit can be used either with an MP160/MP150 using a matched receiver unit, or directly with a BioNomadix Logger. The matched pair emulates a "wired" connection from subject to computer, with all the benefits of a fully-wireless recording system.

Attach the transmitter near or on the subject's torso via the stretchy Velcro strap (included) or use the pocketed, stretch-mesh BioNomadix Shirt and connect the respiration transducer(s) BN-RESP-XDCR. Respiratory signal data is transmitted at a rate of 2000 Hz, providing high resolution respiratory effort waveforms at the receiver module's output.

  • As the subject inspires, the thoracic and/or abdominal circumference expand slightly, increasing the output signal level.
  • As the subject expires, the circumference reduces, dropping the output signal level.

The module pair establishes a fixed wideband response of DC to 10 Hz for monitoring extremely rapid respiratory effort variations (up to 600 breaths per minute) associated with coughing or sneezing, or measuring relatively static respiratory conditions, such as cessation of breathing. Additional internal highpass and lowpass optional filters provide for high quality amplification of respiratory effort signals even during periods of vigorous exercise or activity.

Respiratory effort data can be recorded from two independent sites, typically anywhere on the subject's torso. Use AcqKnowledge to evaluate the difference between thoracic and abdominal respiratory effort. The respiratory effort transducer is sensitive enough to measure the circumferential change associated with each heart beat, so AcqKnowledge can be used to extract both heart rate BPM and breathing rate BPM from respiratory effort signals. Using AcqKnowledge, both fast or slow response respiration data can be isolated to accommodate high quality signal component identification.

Due to battery operation of the wireless transmitter and close proximity to the subject's body, common-mode rejection ratio is extremely high, considerably in excess of any typical wired biophysical transducer signal recording system. Accordingly, the available notch filters to remove mains interference (50 or 60 Hz) are typically not required.

The high signal to noise ratio and high time-based sampling resolution permits the device to be used for precise respiratory studies. Respiratory measurement can also be synchronized to a specific stimulus for stimulus/response investigations, such as those associated with challenge and threat.

Interference with other recording modules or systems is greatly minimized because the module transmitter is completely battery operated and Operates totally independently of any other recording grounds or power sources. The recording transmitter is also extremely safe to use, because there is no physical connection to supply mains.

The transmitter's battery can provide power for up to 72 hours of continuous operation.

The BioNomadix series of wireless, wearable physiology monitoring devices for life science research are available for a wide range of signals, including ECG, EEG, EOG, EMG, EGG, Respiration, Pulse, Temperature, Electrodermal Activity, Impedance Cardiography and Accelerometry. BioNomadix are typically dual-channel units, offering either two of the same signal or a combination of signals.

BioNomadix noninvasively records high-quality, full-bandwidth data while comfortably allowing subjects to move freely in natural indoor environments. Each BioNomadix device consists of two parts, a transmitter that is worn by the subject to amplify and send the physiological data, and a receiver module or BioNomadix Logger. BioNomadix transmitters use digital transmission and short leads or transducers placed close to the signal source to provide excellent signal quality. BioNomadix are configured for specific signal types, so you don’t have to adjust settings on the hardware or software for high quality data.

Multiple BioNomadix units can be used to provide the optimum signal combination for a research study requiring biopotential or transducer signals. When used with a BIOPAC MP System, up to 16 channels of BioNomadix data can be recorded for multi-subject or multi-parameter protocols. The system also works with multiple MP160/MP150 systems or third-party data acquisition hardware via an isolated power supply module (IPS100C). The BioNomadix Logger can pair with up to 3 transmitter units providing up to 6 channels of physiological data as well as a color display for visual feedback, speaker for auditory feedback, vibration for haptic feedback, voice journal for participant comments, event markers, alarms, and a built-in accelerometer.  AcqKnowledge software adds the power of sophisticated automation and scoring routines for each signal type, plus customization options.

BioNomadix accessory items include transducers, electrode leads, and a custom, pocketed stretch-mesh shirt to comfortably hold multiple devices in place. The shirt has zippers placed for easy access to electrode sites and is available from extra small to extra large.

Developed and manufactured by BIOPAC Systems Inc., a leader in life science data acquisition and analysis, the new BioNomadix series delivers all the benefits of a wireless solution with the signal quality & integrity of a wired system. BioNomadix provides a cost-efficient option for uncompromised wireless physiological subject monitoring.

BioNomadix Transmitter and Receiver are shipped as a pair with matching serial numbers and include a strap and battery charger. To identify the matched Transmitter-Receiver Pair, press and hold "ID" button on Transmitter and match to Receiver with flashing "Status" LED.
