Vital signs are measurements of the body’s most basic functions. The following main parameters are normally monitored by medical professionals to identify the illness:

  • Body temperature
  • Pulse rate
  • Respiration rate (rate of breathing)
  • Blood pressure (Blood pressure is not considered a vital sign, but is often measured along with the vital signs)

Vital signs are useful in detecting or monitoring medical problems. Vital signs you may have already noticed, when you get sick, your resting heart rate tends to increase and your heart rate variability tends to decrease.

While you might see these changes during the early stages of an infection, we often don’t experience obvious symptoms. The immune system and the central nervous system work together in complex ways to target a foreign virus even before we’re aware that we are sick.

When infections become severe enough, one coordinated attack these two systems produce is the febrile response, commonly known as a fever. When the immune system detects a foreign pathogen such as a virus or bacteria, it sends a signal to the brain to increase the body’s core temperature, causing the sympathetic nervous system to respond by producing more heat. When the temperature rose by 1 degree C, the heart rate increased on the average by 8.5 beats per minute.

By creating a personal baseline while you are healthy, vital signs daily measurement can be used to identify signs of illness sometimes before you actually feel sick and potentially before a doctor – without recent data of what your personal “normal” looks like – would recognize that something was wrong.

Vital signs monitoring (Body temperature, Pulse rate and Respiration rate) daily measurement can serve as an early detection system and useful in detecting medical problems, such as those demonstrated in persons infected and fighting COVID-19.

Being included in access control procedures, vital signs screening can be effectively used to provide facility-based surveillance for healthcare-associated infections, including infections in healthcare workers and inpatients, which is one of core components of COVID-19 infection prevention and control.

MOD-601 system consists dynamic real-time screening camera installed on special stand with cameras tray and computer. The camera is fitted with RGB sensor, temperature transmitter, two 3D sensors and thermal sensor for infrared thermal imaging.

Artificial Intelligence (AI) video analytics software continuously collects data, calculate the vital signs values, display measurement results, compare these results with normal ranges and provide output for access control.

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
  • Hospitals
  • Marketplaces
  • Offices & Government Buildings
  • Airports & Border Control
  • Retirement Homes
  • Schools and Universities

The implemented in MOD-601 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):

Score 3 2 1 0 1 2 3
Respiratory rate (breaths/min) >35 31-35 21-30 9-20 <7
Temperature (C) >38.9 38-38.9 36-37.9 35-35.9 34-34.9 <34
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 implemented in MOD-601 vital signs screening and early warning functionality, enables to effectively perform multi-parameter screening to identify COVID-19 infected persons. NEWS methodology can be effectively deployed using the early warning score data provided by MOD-601.
