Biopac BN-RSPEC / BN-RSPEC-T - BioNomadix RSP with ECG

The Dual RSP/ECG BioNomadix amplifier system is designed specifically for respiration and electrocardiogram data, enabling you to record one or both signals. 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-RSPEC / BN-RSPEC-T - BioNomadix RSP with ECG

Biopac BN-RSPEC BioNomadix Respiration and ECG Wireless Transmitter & Receiver Pair (for use with MP160/MP150 or BioNomadix Logger)

Biopac BN-ECG2-T - BioNomadix Respiration and ECG Amplifier/Transmitter module only (BioNomadix Logger use only)

The Dual RSP/ECG BioNomadix amplifier system is designed specifically for respiration and electrocardiogram data, enabling you to record one or both signals. 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.

  • RSP (CH A) - use the respiration transducer to measure abdominal or thoracic expansion and contraction while breathing
  • ECG (CH B) - use the 3-lead set and EL504 disposable electrodes to record electrical activity generated by the heart

The high signal to noise ratio and high time-based sampling resolution permit the pair to be used for precise respiratory studies and exacting heart rate variability studies.

The combined pair is specifically designed to measure respiration activity associated with circumferential changes in the thoracic or abdominal regions of the torso. Attach the transmitter near or on the subject's torso via the stretchy Velcro strap (included) or use the BioNomadix BIOSHIRT which incorporates a respiration sensor and fabric electrodes.
  • 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.
Raw RSP data from the module pair is bandlimited from DC to 10 Hz, to provide for the measurement of relatively static respiratory conditions, such as cessation of breathing, up to the extremely rapid respiratory effort variations (up to 600 breaths per minute) associated with coughing or sneezing. Additional internal highpass and lowpass optional filters provide for high quality amplification of respiratory effort signals even during periods of vigorous exercise or activity.

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. Respiratory measurement can also be synchronized to a specific stimulus for stimulus/response investigations, such as those associated with challenge and threat.

Raw ECG data from the pair is bandlimited from 0.05 Hz to 150 Hz, to provide a clinical standard, very high quality recording. AcqKnowledge software automatically scores the data and extracts the measurements of interest on a cycle-by-cycle basis. The results are automatically exported to Excel or pasted in the Journal file. AcqKnowledge also includes a fully automated HRV analysis feature. The HRV analysis provides values for VLF, LF, HF, VHF, sympathetic, and vagal, as well as the sympathetic / vagal balance.

Collect data from just LEAD I and LEAD II to generate LEAD III and all the augmented leads (aVR, aVL and aVF).

Using AcqKnowledge's equation generator, a six-lead ECG can be generated from the two recorded ECG leads from the module pair. Use AcqKnowledge software to provide a complete Lead II ECG analysis.

Using AcqKnowledge, wide bandwidth ECG data can be filtered to lower values to accommodate high quality ECG signal isolation even in the presence of extensive subject motion.

Biopotential amplifier/transmitter signal to noise ratio is very high (in excess of 70 dB), as the noise floor for ECG signal transmission is only 0.9 µV rms (bandwidth 0.05-150 Hz).

The module pair has a fixed gain of 2,000 for the ECG signal. The largest ECG signal which can be measured is 10 mV P-P, the smallest is less than 1 µV rms.

BioNomadix overview

The BioNomadix RSP/ECG Pair consists of two parts, a transmitter that is worn by the subject to amplify and send physiological data, and a receiver module to provide high-quality data. The BioNomadix transmitter uses digital transmission and provides excellent signal quality with an RSP transducer and/or a short electrode lead set placed close to the signal source.

BioNomadix are configured for specific signal types, so you don’t have to adjust settings on the hardware or software for high quality respiration or electrocardiography data.

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. 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 matched pair incorporates internal, non-distorting, highpass and lowpass filters to provide for high quality amplification of the complete waveform.

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.
