What Are Biosignals?
Biosignals are measurable electrical, mechanical, chemical, or biological signals produced by the human body. Healthcare professionals use biosignals to monitor how different organs and body systems are functioning, helping diagnose diseases, track recovery, and guide treatment decisions.
Many modern medical devices rely on biosignals to provide real-time information about a person’s health.
Why Biosignals Matter
Biosignals allow healthcare providers to detect changes in the body’s function, monitor chronic conditions, evaluate treatment effectiveness, and identify medical emergencies more quickly.
Common Types of Biosignals
- Electrocardiogram (ECG or EKG) for heart activity
- Electroencephalogram (EEG) for brain activity
- Electromyogram (EMG) for muscle activity
- Respiratory signals
- Blood pressure measurements
- Blood oxygen saturation (SpO₂)
- Body temperature
How Biosignals Are Used
- Monitoring heart rhythm
- Assessing brain function
- Evaluating muscle disorders
- Tracking breathing patterns
- Monitoring recovery after illness or surgery
- Managing chronic medical conditions
How Home Care Can Help
Home care professionals monitor vital signs and other health indicators when appropriate, recognize changes that may require medical attention, encourage adherence to treatment plans, and communicate important findings to the healthcare team.
Home Care Tip
Home monitoring devices should be used according to your healthcare provider’s instructions, and abnormal readings should always be reported promptly.
Frequently Asked Questions About Biosignals
Are vital signs considered biosignals?
Yes. Heart rate, blood pressure, breathing rate, body temperature, and blood oxygen levels are examples of important biosignals used to assess overall health.
Can biosignals be monitored at home?
Yes. Many biosignals can be monitored using home medical devices, including blood pressure monitors, pulse oximeters, glucose meters, and wearable health technology.
Can home care professionals monitor biosignals?
Yes. Home care professionals can monitor appropriate health measurements, observe changes in condition, and report concerns to healthcare providers.
When to Contact Your Healthcare Provider
Contact your healthcare provider if home monitoring devices consistently show abnormal readings or if you experience new or worsening symptoms.
