Monitor Description

Patient safety All invasive procedures involve risks to the patient. Use aseptic technique. Follow the instructions provided by the catheter manufacturer. The output signals are not floating and they must not be connected directly to a patient. Connect only one patient to one monitor at a time. Constant attention by a qualified professional is needed whenever a patient is under anesthesia or connected to a ventilator. Some equipment malfunctions may pass unnoticed in spite of the monitor alarm. Do not use antistatic or electrically-conductive breathing tubes. They may increase the risk of burns when an electrosurgery unit is used. Do not use the Cardiocap/5 during magnetic resonance imaging (MRI). Use only approved accessories, mounts and defibrillator-proof cables and invasive pressure transducers. For a list of approved supplies and accessories, see the "Supplies and Accessories" catalog. Other cables, transducers and accessories may cause a safety hazard, damage the equipment or system, result in increased emissions or decreased immunity of the equipment or system or interfere with the measurement. Protection against cardiac defibrillator discharge is due in part to the accessories for pulse oximetry (SpO2), temperature (T) and invasive pressure (P) measurement. Single-use accessories are not designed to be re-used. Re-use may cause a risk of contamination and affect the measurement accuracy. To prevent erroneous readings, do not use physically damaged sensors or sensor cables. Discard a damaged sensor or sensor cable immediately. Never repair a damaged sensor or cable; never use a sensor or cable repaired by others. A damaged sensor or a sensor soaked in liquid may cause burns during electrosurgery.

ECG, Impedance respiration, Invasive blood pressure Ensure proper contact of the return electrode of the electrosurgery unit to your patient to avoid possible burns at sensor sites.

ECG, Impedance respiration, NMT Make sure that the lead set clips or snaps do not touch any electrically conductive material, including earth.

Impedance respiration In obstructive apnea, respiration movements and impedance variations may continue.

NIBP The monitor sets the inflation pressure automatically according to the first measurement. Reset the case to reset the inflation limit before measuring a new patient.

Invasive blood pressure Make sure that no part of the patient connections touches any electrically conductive material, including earth.

Patients with pacemakers or arrhythmia The monitor may count pacemaker pulses as heart beats during cardiac arrest, some arrhythmias, and with certain types of pacemakers particularly in ON R mode. Do not rely entirely upon rate meter alarms. Keep patients with pacemakers and arrhythmias under close surveillance. The impedance respiration measurement may cause rate changes in Minute Ventilation Rate Responsive Pacemakers. Set the pacemaker rate responsive mode to off or turn off the impedance respiration measurement on the monitor.

Cardiocap/5 for Anesthesia User’s Reference Manual

Gases MAC values are empirical, not absolute. Cardiocap/5 MAC values correspond to those of healthy adults and cannot be applied to children. Age and other individual factors influencing the effect of volatile agents are not taken into account.

Pulse oximetry Use clean and dry sensors and cables only. Moisture and debris on connectors may affect measurement accuracy. Patient conditions (such as reddening, blistering, skin discoloration, ischemic skin necrosis, and skin erosion) may warrant changing the sensor site frequently or using a different style of sensor. For details, refer to the instructions supplied with the sensor. Conditions that may cause inaccurate readings and impact alarms include interfering substances, excessive ambient light, electrical interference, ventricular septal defects (VSD), excessive motion, low perfusion, low signal strength, incorrect sensor placement, poor sensor fit, and/or movement of the sensor on the patient. To prevent erroneous readings, do not use an inflated blood pressure cuff or arterial blood pressure measurement device on the same limb as the oximeter sensor.

Temperature To prevent patient injury, use Datex-Ohmeda temperature probes only.

Alarms Make sure that necessary alarm limits are set and alarms are on when you start monitoring a patient. When alarms are suppressed, observe the patient frequently.

Cautions A CAUTION indicates a situation that may cause damage to the unit or devices connected to it.. US Federal law restricts this device to sale by or on the order of a licensed medical practitioner. The system is intended for use by qualified medical personnel only. Do not apply pressurized air to any outlet or tubing connected to the monitor. Pressure may destroy sensitive elements. Do not store the monitor outside the specified temperature range (-10 to + 50 °C / 14 to 122 °F). Do not subject memory cards to excessive heat, bending, or magnetic fields. Leave space for circulation of air to prevent the monitor from overheating. Turn off the power before making any rear panel connections. Use only cables and accessories approved by Datex-Ohmeda. Other cables and accessories may damage the system or interfere with measurement. Single-use accessories are not designed to be reused. Vibrations during transport may disturb SpO2, ECG, impedance respiration, and NIBP measurements.

Airway gas measurement Strong scavenging suction may change the operating pressure of the monitor and cause inaccurate readings or internal damage.
