Action

The firm Nihon Kohden OrangeMed, Inc., sent an "URGENT-Medical Device Correction Recall Safety Notice" letter to its customers on July 26, 2021. The letter describes the product, issues and actions to be taken. The customers were instructed to do the following prior to actions being implemented by the manufacturer: 1. Pass this notice on to all those who need to be aware within your organization and to any organization where the affected devices have been transferred. 2. Perform Device Check and Circuit Check as instructed in the NKV-550 ventilator Operator s Manual. A defective regulator can be identified during the Device Check and Circuit Check. 3. If the gas outlet from the hospital wall has an individually adjustable pressure regulator, adjust the outlet pressure to 16 psi for the air and O2 gases at the NKV-550 ventilator. This will allow the ventilator not to depend on its internal regulators to regulate the gas pressure. 4. If the ventilator has a failed internal regulator, remove the ventilator from service and contact the manufacturer or your local representative of the manufacturer. 5. Please complete the attached acknowledgement form and return to FSN@orange-med.com within 5 days of receipt. Please review and distribute the information with your staff members who need to be aware of the contents of this communication. Please retain a copy of this notice and include it with the Operator s Manual of this device. For further information, please contact your local representative of the manufacturer or email the manufacturer at FCN@orange-med.com.
