With the ultimate portability, the Capno-1 can be used everyday in surgery, dentistry, emergency and critical care, and a variety of other procedures.
- Real-time CO2 waveforms (capnogram)
- End-tidal CO2 (ETCO2)
- Fractional inspired CO2 (FiCO2)
- Respiratory rate (RR)
- Audible and visual apnea alarms
Conventional side-stream capnographs on the market, designed mainly for use in human patients, usually need a large sample flow rate (100 - 250 ml/minute). When used in small veterinary patients, such as cats and small dogs, due to their small tidal volumes, these capnographs may produce inaccurate readings and distorted waveforms. In addition, a large sample flow rate aspirates water and secretions into the sampling line, resulting in occlusions and erroneous measurements, and removes a large portion of the anesthetic gas out of the breathing circuit, increasing anesthesia cost and pollution in the surgical room. The monitors based on microstream capnography (with a sample flow rate of 50 ml/minute), however, require a special disposable sample line with a built-in filter. Due to the accumulated high cost for the expensive disposable sample lines, microstream capnography is not cost-effective for veterinary practices. To obviate these problems, VetSpecs developed the new state-of-the-art micro-flow™ side-stream capnography, which has the same low sample flow rate of 50 ml/minute as the microstream capnography, but without using a special expensive disposable sample line.
The Capno-1 employs the VetSpecs® micro-flow™ capnography, which is suitable for use in a wide range of veterinary patients, including cats and dogs of all sizes, producing best performance with minimal operating costs.
Why Capnography?
Capnography is the measurement and waveform display of CO2 concentration at the patient’s airway. Capnograph, dubbed as Anesthesia Disaster Early Warning System, monitors various components of patient and anesthesia equipment as well as the critical connection between the two, and provides extremely pertinent information, including CO2 production, pulmonary perfusion, alveolar ventilation, respiratory patterns, and elimination of CO2 from the anesthesia circuit, without the need for invasive techniques or a significant investment in time. Capnograph can also reduce expenditure on medical gases and inhaled anesthetic agents. During procedures done under sedation, a capnograph provides more useful information, e.g. on the frequency and regularity of ventilation, than a pulse oximeter. Capnography provides an immediate picture of patient apnea, while pulse oximetry is delayed for several minutes. According to the American Society of Anesthesiologists, capnography is mandatory for all patients receiving general anesthesia.
