    Study Notes

    Veterinary Anaesthesia Monitoring Techniques and Considerations

    • Monitoring depth of anesthesia involves observing eye reflexes, position, jaw tone, and eye movements, and it can be measured by watching the chest and the breathing system's reservoir bag.
    • Respiratory rate is 8-20 for dogs and 15-30 for cats, but it is a relatively poor indicator of respiratory adequacy compared to CO2 levels measured by capnography.
    • Pulse palpation of auricular, lingual, brachial, metacarpal, femoral, coccygeal, and dorsal pedal arteries provides information on peripheral perfusion and heart rate.
    • Good pulses do not always equal good blood pressure, as pulse pressure does not reflect absolute values, and arrhythmias may be detected as "dropped beats".
    • Legal requirements mandate monitoring trends, recording drugs/interventions, and identifying complications during anesthesia.
    • Good interpretation of monitoring data is essential, as additional monitoring may increase anesthesia time and is not a substitute for basic monitoring.
    • Monitoring techniques include respiratory pulse oximetry, capnography, ECG, blood pressure, urine output, and arterial blood gas analysis.
    • Pulse oximetry measures SpO2, which should be above 90% in animals breathing room air and above 95% in anesthetized animals breathing 100% oxygen.
    • Factors affecting pulse oximetry readings include pigmented skin, movement, compression of the vascular bed, ambient light, and various health conditions.
    • Cyanosis, the blue color of arterial blood when deoxyhemoglobin is present, is not always a reliable indicator of desaturation, and pulse oximetry is more sensitive for its detection.
    • Capnography measures end-tidal CO2, with normal values of 4.6 – 6 kPa in animals with normal lungs, providing information on respiratory rate and indicating hypo- or hyperventilation under anesthesia.
    • Mainstream and sidestream analyzers provide different information, such as respiratory rate, EtCO2, inspired CO2, and "the trace", and action is required above an EtCO2 of 8.
