DSI Implant Specification Overview

Extra-small implants

For use with mice and other similarly sized animals

* Implants can measure respiratory rate from pleural pressure.
** 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). **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 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.
