The Indus Rodent Surgical Monitor⁺ is an advanced, integrated surgical warming and vital signs monitoring solution for preclinical research in mice, rats and other small animals. The system provides detailed information, in real time, regarding subject body temperature, ECG, heart rate, pressure and respiration. The system incorporates intelligent zone heating, ultra-low noise, high-resolution ECG electronics, noninvasive electrodes, and a port for external needle electrodes for when subjects cannot be laid prone or supine.

A standard setup consists of three components:

• Touchscreen Display Unit
• Heated Surgical Platform 
• Temperature Probe

Optional components:

• Pulse Oximetry Thigh Clip
• Pressure Adapter Cable and Pressure Catheter  
• External Needle Electrodes

Configurable, clear waveforms and numeric panels provide information to monitor subject physiological status. Recording, playback and export functions are included to make data collection easy.

Each Rodent Surgical Monitor⁺ is delivered with a single rectal temperature probe. Customers may select between probes ideal for adult mice or for adult rats.

The temperature probe sensor is a Copper-Constantan Thermocouple, located at the tip of the probe. Probe temperature resolution is +/-0.1°C. Calibrated probe accuracy is +/-0.1°C at operating temperature.

The Pressure Catheter Option includes a software and firmware update, along with a catheter connection cable. When connected to an Indus pressure catheter, measurements of arterial and ventricular pressures can be performed. This adds another real-time continuous data stream to the Rodent Surgical Monitor⁺.

The Indus high fidelity rodent pressure catheters are specifically designed for use with mice and rats. These catheters have solid state sensors mounted at the tip that measure pressures with a high degree of precision. They are ideal for arterial, venous, or ventricular pressures due to the solid state sensor’s ability to accurately respond to minute and rapid changes in pressure.

The Pulse Oximeter Option includes a software and firmware update, along with a sensor clip. This option allows you to noninvasively measure arterial blood oxygenation.  This adds another real-time continuous data stream to the Rodent Surgical Monitor⁺, providing valuable information about depth of anesthesia and ventilation efficacy.  Pulse oximetry has been mandated in hospital care for more than a decade: the preclinical research community has taken note of this and current NIH guidelines repeatedly suggest monitoring pulse oximetry during surgery and postoperative care to ensure correct anesthesia delivery and ventilation.

The 4 or 8 Channel Analog Output Cable provides the capability to acquire raw data from the Rodent Surgical Monitor+, in real time, with virtually any data acquisition system. A total of four or eight output channels are included, each configurable for optimal data output. In addition, the cable can be used as an R-trigger for ultrasound imaging systems, as a TTL trigger for high-speed dual camera image capture systems and to supply data to many different brands of data acquisition systems.  Each channel can be individually configured with its own filtering options.
