Modcon’s latest VsScan (MOD-601) is a real-time screening analyzer enhanced with two 3D sensors, a RGB sensor, temperature transmitter, and thermal sensor that allows for thermal imaging. Modcon’s AI (Artificial Intelligence)-based video analytics software collects and calculates data and vital signs values. Additionally, there is a display of measurement results that compare results with normal ranges. Once data is collected and read, it determines an output for access control.
The vital signs monitoring system is designed to produce assessment results effectively by using its multi-parameter screening and early-warning methodology. The EWS (Early Warning Score) is based on vital signs from studies in the 1990s, which indicated unusual changes in vital signs before the onset of cardiac arrest or in-hospital deterioration.
Vital signs monitoring (Body temperature, Pulse rate and Respiration rate) is mainly used at control gates and enables the most accurate and fastest screening of persons at the following locations:
- Industrial Facilities
- Offices & Government Buildings
- Airports & Border Control
- Retirement Homes
- Schools and Universities
|Body Temperature||Heart Rate (HR)||Respiratory Rate (RR)|
|Detection accuracy||± 0.5 °C||± 5 BPM||± 2 BPM|
|Measuring speed||0.7 – 2 seconds||10-15 seconds||10-15 seconds|
|Detection Distance||0.2-2 m||0.5-1 m||0.5-1 m|
The implemented in VsScan early warning score (EWS) is based on a guide used by medical services to quickly determine the degree of illness of a patient. It is based on the vital signs which were developed in the late 1990s when studies showed that in-hospital deterioration and cardiac arrest was often preceded by a period of increasing abnormalities in the vital signs.
The resulting observations are compared to a normal range to generate a single composite score, based on the following diagram (an early modified EWS):
|Respiratory rate (breaths/min)||>35||31-35||21-30||9-20||<7|
|Heart rate (bpm)||>129||110-129||100-109||50-99||40-49||30-39||<30|
In a pandemic like COVID-19, rapid assessment of persons is essential. A fast and easily calculated score, such as NEWS (National Early Warning Score) could help to provide facility-based surveillance for healthcare-associated infections, including infections in healthcare workers and inpatients, which is one of core components of infection prevention and control.
The VsScan (MOD-601) is primarily used at control gates of hospitals, airports, industrial facilities, offices, governmental buildings, schools, universities, retirement homes, and various marketplaces – places like these have more foot-traffic than usual and the vital signs monitoring facilitates a rapid scanning process.
