NAVOYCDS is intended to be used with patient data from already cleared patient monitoring devices which measure respiratory rate, systolic blood pressure, and Glasgow Coma Scale (GCS) in adult patients being monitored in a healthcare facility. The device uses an algorithm to calculate a qSOFA score (also known as quickSOFA) which indicates adult patients with suspected infection who are at greater risk for a poor outcome. It uses three criteria, assigning one point for low blood pressure (SBP ≤100 mmHg), high respiratory rate (≥22 breaths per min), or altered mentation (Glasgow coma scale <15).
NAVOYCDS is an adjunct to and is not intended to replace vital signs monitoring.
NAVOYCDS is intended to provide additional information for use during patient monitoring in a healthcare facility. NAVOYCDS is not intended for making clinical decisions regarding patient treatment or for diagnostic purposes.
The device is intended for an adult population.
Indications for use as stated in the FDA summary.
