The EasyOne Connect software for the Easy on-PC offers a variety of animated screens for children as well as adults. These incentive screens, in addition to the real-time curves, encourage the patients to help them achieve high quality spirometry results. Here are some examples of the pediatric incentive screens available:
Data can safely be exported by using the “Export Data” feature or “Backup” feature within the Storage tab in the configuration.
All EasyOne products are designed to require no calibration and only minimal maintenance. We do not recommend a specific schedule for calibration checks. The device is designed to remain in calibration throughout its lifetime. A number of independent papers have been published that confirm this long-term stability.
However, within the industry, there are published standards where recommendations and requirements for calibration verification are set. For example, the ATS recommends daily calibration checks on all spirometry equipment, regardless of manufacturer. Further, all testing that falls under the requirements of NIOSH/OSHA and Social Security/Disability should be accompanied by a daily calibration check. For those wishing to perform calibration checks ndd offers a 3-Liter calibration syringe.
Yes, ndd’s products are all completely HL7 compatible through EasyOne Connect, the free companion PC software, enabling connectivity to virtually all EMRs. We would be happy to work with you to configure an interface for your particular EMR system. We are also constantly working to expand our library of dedicated integrations.
