Recall Class: Class I

Date Recall Initiated: October 21, 2011

  • Therapy Support Inc.
  • Mendo-Lake Home Respiratory Services
  • MedAssurance Inc.

Use: The 7600 Bubble Humidifier is used for supplemental oxygen therapy. The humidifier is used to provide additional humidity to supplemental oxygen therapy. This product is a single-use device used in health care facilities and home health care.

Recalling Firm:

Salter Labs
100 Sycamore Road
Arvin, California 93203

Reason for Recall: A manufacturing defect was discovered internally which indicated that, in certain lots of the 7600 Bubble Humidifiers, the humidifier lids failed to pop off at the intended pressure. Also, when the pop-off does occur, the brass slug does not always reseat to the appropriate position. When the slug fails to reseat properly, the humidifier can leak.

For conscious adult patients and in hospital settings with well trained personnel, the leak characteristic of this defect would be obvious. However, for an unconscious, critically ill patient, or for an infant, or child patient, or a home care patient, the leaking may not be obvious to the patient or to the caregiver in a home care situation.

A humidifier leak will potentially interrupt the flow of supplemental oxygen to the patient. Hypoxemia may develop resulting in death or serious adverse health consequences. The firm has received a total of 0 reports of incidents in which the device has apparently malfunctioned, including 0 injuries and 0 deaths.
