DSI Implant Specification Overview

Extra-small implants

For use with mice and other similarly sized animals

* Implants can measure respiratory rate from pleural pressure or derived from the blood pressure channel using the BPR analysis module.
** Sensor often functions for 6-8 weeks; warranty is 4 weeks.

Small implants

Species commonly monitored include rats, ferrets, marmosets, guinea pigs, and others.

* Implants can measure respiratory rate from pleural pressure, diaphragmatic EMG (it is recommended to acquire ECG with dEMG for filtering out ECG contamination during respiratory rate analysis), or derived from the blood pressure channel using the BPR analysis module. **Available in two frequencies: 455 kHz (F0) and 18 MHz (F2). Pair housing capable.
***Sensor often functions for 6-8 weeks; warranty is 4 weeks.
^#Available in two frequencies: 8 MHz (F1) and 18 MHz (F2). Pair housing capable.
^##Available with an external thermistor probe if desired.

Large Animal Telemetry

DSI offers multiple telemetry implants options for large animals such as canines, non-human primates, swine, sheep, and similar sized animals that measure a variety of parameters.

* L11R and D70-PCTR can measure respiratory rate and volume via impedance; other implants can measure
respiratory rate from pleural pressure, blood pressure (using BPR analysis module) or diaphragmatic EMG.
** All L21 and L11 models are manufactured with the Solid Tip Lead, unless requested otherwise.
^Warranted battery life for China is 85 days for L03 and 90 days for L04.
^# LV capable L11R warranted battery life is 105 days.
