Acute, subacute/subchronic, and chronic toxicity from the exposure to these compounds from the intended use of this device are not expected. WARNING: The device can only be isolated from the main power supply by removing the power cord completely. • •

Ensure the power socket is always accessible for disconnection. DO NOT disconnect the power cable unless for Service purposes or transport.

WARNING: DO NOT modify the equipment. WARNING: Before applying non-original accessories, ensure that they are biocompatible. All accessories supplied by ACUTRONIC Medical Systems for use on fabian ventilators are biocompatible. WARNING: When connected to a patient DO NOT simultaneously touch the external power supply cord and the flow sensor connector cable. WARNING: if the strength of the auditory alarms is less than the ambient sound this might impede an operator to recognize alarm conditions. WARNING: NEVER cover the ventilator when in use. WARNING: DO NOT position the ventilator in such a way that adversely affects its performance or makes it difficult to disconnect the ventilator from the mains supply. In case of emergency, removal of the mains plug from the wall outlet disconnects the ventilator from mains power . WARNING: in case of ventilator failure, the lack of immediate access to appropriate alternative means of ventilation can result in patient death. WARNING: Ensure that alarms are appropriately set before use of ventilator on a patient. WARNING: In case portions of the gas pathways through the VENTILATOR become contaminated with body fluids or expired gases during NORMAL CONDITION or SINGLE FAULT CONDITION, immediately contact ACUTRONIC Medical Systems WARNING: • •

Description NOTE: In general, it should be noted that ventilation of children should only be carried out by clinically trained specialists who have sufficient knowledge of ventilation of patients of specified age. WARNING: DO NOT use the etCO 2 module in the presence of flammable anesthetics or other flammable substances in combination with air, oxygen-enriched environments, or nitrous oxide. WARNING: Check alarm limit settings each time the etCO 2 module is used. WARNING: The etCO 2 module is intended only as an adjunct in patient assessment. It must be used in conjunction with assessment of clinical signs and symptoms. Before use, carefully read the following literature: • •

Oximetry Sensor Directions for Use PC-Series Patient Cable Directions for Use

EXPLOSION HAZARD: DO NOT use the oximeter in the presence of flammable anesthetics or other flammable substances in combination with air, oxygen-enriched environments, or nitrous oxide. Check alarm limit settings each time the oximeter is used. A pulse oximeter should NOT be used as an Apnea monitor. A pulse oximeter should be considered an early warning device. As a trend towards patient deoxygenation is indicated, blood samples should be analyzed by a laboratory co-oximeter to completely understand the patient's condition. Always remove the sensor from the patient and completely disconnect the patient from the oximeter before bathing the patient. DO NOT use malfunctioning equipment. Have the unit repaired by Masimo or a qualified service person. ELECTRIC SHOCK HAZARD: Do not remove the pulse oximeter cover. There are no user-serviceable items inside the oximeter. • •

An operator may only perform maintenance procedures specifically described in this manual. ONLY connect IEC 60601-1 or IEC 60950-1 compliant devices to Ethernet, Nurse call, and RS232 ports.

If the accuracy of any measurement by the oximeter does NOT seem reasonable, first check the patient's vital signs by alternate means, and then check the oximeter for proper functioning. WARNING: DO NOT use the ventilator in association with HF (High Frequency) electrosurgical equipment. WARNING: Connect SpO 2 and etCO 2 sensor cables to the machine before the patient is connected.
