Only use the Nippy 4+ with accessories approved by Breas Medical. Incompatible parts can result in degraded performance and change of pressure gradient. If unapproved accessories are used, Breas Medical has no responsibility for the safe and effective use of the Nippy 4+. The responsible organization is responsible for ensuring the compatibility of the ventilator and all parts used to connect to the patient before use. Changes to the patient circuit, like adding or removing accessories or changing type or length of breathing tube, may affect both circuit compliance and alarm triggering conditions. It’s recommended to perform a pre-use test and re-test the alarm function after making changes to the patient circuit. When a patient is treated, there must be a supervising person present during the treatment in order to take care of alarms and conditions that the patient cannot solve on their own. Always have immediate access to an alternative means of ventilation, which is ready for use, to avoid patient death or serious injury. Failure to have an alternate means of ventilation can result in serious injury or patient death if ventilator fails.

Doc. 007303 D-2

Safety Information 17 Nippy 4+ User manual

To prevent death or serious injury, monitor the patient and the ventilator regularly in order to determine the need to provide emergency ventilation when an alarm sounds or the ventilator malfunctions. If using the ventilator in a transport case, only use the protective cover listed as approved accessory to prevent adverse ventilator performance, which can consequently result in patient death. Measured values for volume and expired CO2 may differ from the actual patient values due to unintentional leaks. Do not obstruct the gas intake port. To prevent disconnection of the patient circuit during use, only tubes in compliance with ISO 5367 or ISO 80601-2-74 should be used. The ventilator may not work properly if any part has been dropped, damaged or submerged in water.

WARNING! Risk of Burns Covering breathing tubes with a blanket or heating them with an overhead heater can affect the quality of the therapy or injure the patient.

WARNING! Risk of Faulty Treatment If the patient is admitted to a hospital or is prescribed any other form of medical treatment, always inform the medical staff that the patient is on mechanical ventilation treatment.
