Manufacturer Reason
for Recall
Analysis of a customer complaint has shown that during ventilation of small pediatric patients with high airway resistance and low lung compliance, the oxygen consumption of a Hamilton T1 ventilator with software versions 1.1.2 and lower must be calculated using a larger margin than originally expected.
FDA Determined
Cause 2
Software design
Action Hamilton sent a Field Safety alert letter dated January 11, 2013 to all customers. The letter identified the affected product, explained the potential problem and a included Medical Device Safety Alert and Corrective Action document. Hamilton is working on a new software version for this issue. Customers are asked to update their operator manual with the update oxygen consumption formula page which provided revised information for calculating oxygen capacity. When the new software is available, Hamilton will provide loaner devices to each location while their unit is being upgraded. Questions should be addressed to Hamilton Medical at 800-426-6331 ext 215
