B40/B20 Patient Monitor17-2• When using the CARESCAPE respiratory modules and Airway Gas Option module withvolume controlled ventilation at low tidal volumes, the specified gas withdrawal rate maysignificantly reduce the amount of gas delivered to the patient.• CARESCAPE respiratory modules and Airway Gas Option: Make sure to compensate forthe possible reduction of tidal volume caused by the 120 ml/min gas sample flow.• E-miniC module: Do not use this module on patients that cannot tolerate the removal of150 ml/min from their total minute ventilation.• A failure in zeroing or calibrating airway gases may cause inaccurate readings.• E-miniC module: O 2, N2 O and anesthetic agent gases may interfere with EtCO2 readings.• EQUIPMENT FAILURE OR INACCURATE READINGS — Planned maintenance should becarried out annually according to the instructions given in the technical manual. Failureto implement the recommended maintenance schedule may cause equipment failure orinaccurate readings.• PATIENT CROSS-INFECTION — Returning the sampled gas to the patient circuit causes arisk of patient cross-infection.• PATIENT CROSS-INFECTION — Always use a bacterial breathing system filter proximal tothe patient when returning the sampled gas to the patient circuit. If a bacterial breathingsystem filter is not used, a failure in the D-Fend Pro water trap may cause a risk of patientcrossinfection.• PATIENT CROSS-INFECTION — If the sampled gas is returned to the patient circuit, ensurethe protective function of the D-Fend Pro water trap by replacing it at least once a week,or immediately in case of a defective or missing bacterial breathing system filter.Otherwise, there is a risk of patient cross-infection.• When use Airway Gas Option module (N-CAiO) for anesthetic agent measurement, makesure the agent is no more than one.Cautions• Do not apply pressurized air or gas to any outlet or tubing connected to the monitor,pressure may destroy sensitive elements.• Patient-specific MAC is affected by several factors such as patient age and bodytemperature.
