Remote breathing monitoring offers improved patient comfort and accuracy for COVID-19 screening. This review compares contact and non-contact radar techniques for vital sign monitoring.
Area of Science:
- Biomedical Engineering
- Medical Devices
- Respiratory Monitoring
Background:
- Breathing rate monitoring is crucial for hospitalized COVID-19 patients.
- Non-contact methods enhance patient comfort and data accuracy by avoiding device-induced distress.
- Remote monitoring aids in screening for COVID-19 by identifying abnormal respiratory patterns.
Purpose of the Study:
- To review recent advancements in breathing monitoring techniques.
- To present and compare both contact and non-contact approaches.
- To discuss integrated solutions using radar technologies for remote respiratory monitoring.
Main Methods:
- Review of existing literature on breathing monitoring techniques.
- Categorization into contact and non-contact methods.
- Analysis of continuous wave (CW) Doppler radar and ultrawideband (UWB) pulsed radar systems.
Main Results:
- Non-contact methods offer superior patient comfort and accuracy but present higher setup complexity.
- Contact methods are often implemented with discrete components.
- Integrated non-contact solutions, particularly radar-based systems, show significant development.
Conclusions:
- Non-contact radar technologies are promising for remote COVID-19 patient monitoring.
- Comparison of radar chip performances aids in selecting appropriate monitoring solutions.
- Further development in non-contact methods can improve accessibility and effectiveness in healthcare settings.

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
