DRE offers the new Respironics Novametrix CO2SMO Veterinary CO2 Monitor and Pulse Oximeter.

Veterinary Capnograph

  • The CO2SMO is a lightweight, portable monitor which verifies critical ventilation and oxygenation information in virtually any clinical setting; from emergency hospital transport to continuous monitoring in the OR, ED, or ICU.
  • Utilizes the CAPNOSTAT mainstream CO2 sensor with patented solid state design and standard two year unconditional warranty!
  • Designed for hassle-free performance in both prolonged and spot check monitoring situations, even under the most adverse airway conditions.
  • Monitors both intubated and non-intubated patients.
  • Convenient "On-Cable" accuracy verification eliminates the need for bulky calibration gas cylinders.

Veterinary Pulse Oximeter

  • Advanced SuperBright™ digital technology provides superior performance in conditions of low perfusion or motion artifact.
  • Innovative reusable Y-Sensor™ is sterilizable and can be used with all patient populations.
  • Unique sensor management plan guarantees fixed operating costs and practically eliminates the burden of tracking and handling sensors.
  • On-screen plethysmogram with autogained/non-gained selection provides continuous validation of signal quality.
