1. The Capno 40 features a digital respiratory sound which is originated from real time CO2 measurements The rhythm of the sound reflects the respiratory rate of the patient while the tone of the sound responds to real time CO2 registered in each breath The respiratory sound allows you to continuously assess the patient s respiration status without watching the screen frequently The respiration sound can be set on or off as default in the menu The volume of the respiration sound can be adjusted by pushing or 4 key _12 Troubleshooting Problem The capnogram seems normal but the CO2 value is erroneously high Possible causes and corrective actions The CO2 module was not calibrated properly Re calibrate the CO2 module Problem The capnogram is very erratic or just a flat line on the CO2 channel Possible causes and corrective actions The CO2 module is malfunctioning Test the CO2 module on yourself by breathing through the airway adapter If the CO2 module registers normally try it again on the patient If not it needs to be replaced 2 2 Pulse oximetry 1 The concept Pulse oximetry provides a noninvasive and continuous estimate of oxygen saturation of hemoglobin in arterial blood SpO2 is commonly used when referring to oxygen saturation readings obtained from a pulse oximeter Pulse oximetry combines the principles of photoelectric plethysmography and spectrophotometry to determine arterial hemoglobin ox2.
