FDA flags ventilator maker over unsubstantiated 'MRI-safe' labeling

FDA has warned a medical device manufacturer that its 'MRI-safe' ventilator claims may lack adequate supporting evidence, following a federal inspection. MRI safety labeling for life-support devices carries direct patient-safety implications.

• FDA inspection raised concerns that the manufacturer's MRI-conditional/safe ventilator claims are not sufficiently validated — specific devices and company name not detailed in source snippet.
• MRI safety designations for ventilators matter in practice: patients on ventilatory support sometimes require MRI, and inaccurate labeling could expose them to projectile, heating, or interference risks.
• Limitation: details of the warning letter (specific findings, required corrective actions, timeline) are not available from the snippet; full regulatory implications remain unclear.
