Mobile patient monitoring

Meru Networks wireless LANs have been verified to reliably deliver life-critical information from Dräger’s patient-worn monitors, following comprehensive interoperability tests.

The tests ensure that hospitals and other healthcare facilities can use Dräger’s Infinity OneNet architecture and Infinity M300 patient-worn monitors with Meru’s single-channel, virtual-cell wireless architecture with the assurance that the combined solution will deliver vital patient data to healthcare professionals in a consistent and timely manner and with a guaranteed quality of service (QoS).

The two companies have initiated additional testing efforts to verify interoperability of Meru WLANs with other Dräger products, including the company’s Infinity Delta, Gamma and Vista series of bedside patient monitors.

“The critical nature of patient data requires that we go through rigorous verification of any products that will be used to communicate between medical systems,” said Lars Roth, product manager for networks at Dräger. “We must be sure that a patient’s vital sign information reaches caregivers in near realtime – even while the patient is ambulatory. Meru’s virtual cell architecture and airtime fairness algorithms allow Dräger monitors to roam seamlessly across large hospital campuses, while ensuring needed reliability and QoS levels.”

The Dräger test suite verified that Meru’s Air Traffic Control algorithms enhanced traffic handling, wireless roaming, encryption and load testing. QoS tests with competing traffic were run to ensure that, in a shared Dräger Infinity OneNet network which runs both patient monitoring and hospital applications, the data from the patient monitors will always be prioritised over less critical data.
