COVID-19 Update

COVID-19 UpdateAs the situation surrounding COVID-19 (Coronavirus) continues to develop, Watermark Medical’s focus on the health and safety of our staff, partners, customers and patients is our top priority. We are closely monitoring guidance from the CDC and other public health organizations and taking appropriate action to ensure we continue to provide uninterrupted technical support, as well as maintain clinical and diagnostic services for our home sleep testing clients. While most of our technical and clinical staff are working remotely, we currently maintain shipping/receiving and quality assurance services from our office to manage device maintenance and repair requirements.

A few questions regarding the coronavirus outbreak have been specifically asked about the cleaning processes of the ARES device. Our cleaning procedure (when followed as described in the ARES Product Guide) has been validated and meets agency guidelines to mitigate the transfer risk of bacteria and viruses. For our customers safety, the ARES User Guide intended to be given or reviewed with each patient, includes instructions for the patient to place the device back in the plastic bag to return to the issuing facility. Once cleaned, storing the ARES device in a new resealable plastic bag will help ensure that the ARES remains clean and ready for the next patient use. Those who clean the devices after patient use can limit their chance of exposure by proper use of gloves and frequent washing of their hands. We are monitoring guidelines from CDC and other regulatory agencies and will adjust our procedure if their recommendations change.
