UFI RESP1
Impedance Pneumograph
The RESP1 uses bioimpedance to make respiration physiometry easy!
Use the RESP1 to monitor the larger trans-thoracic and trans-abdominal impedance changes that result from respiration. Merely placing two electrodes across the area of interest allows the RESP1 to monitor respiration not only in humans, but also in a wide variety of animals.
The RESP1 induces a small and safe high-frequency (30KHz) current to flow between the electrodes, and then senses the resulting voltage across the same electrodes. No balancing is required; the RESP1 output signal always returns to the zero baseline.
