Aidmed One - a portable medical device.
- Bioimpendance – measuring changes in chest volume;
- Accelerometer – measurement of patient movement and position;
- Pressure sensor – airflow through the nose/mouth;
- Thermometer – skin surface temperature;
- Microphone – volume level (sound pressure, such as coughing);
- ECG – one discharge based on silicone electrodes without gel;
- SpO2 sensor – pulse rate and oxygen saturation of the blood – wireless sensor
Aidmed One has several modules for measuring physiological parameters. The ECG signal is collected using a single-channel module through silicon electrodes placed on a chest strap.
This module is also used to detect changes in the electrical impedance of the chest. These occur during breathing – as the shape of the chest changes during inhalation and exhalation, and conductivity changes of the high-frequency current through the tissues. From these changes, the respiratory rhythm can be determined.
Another module is the differential pressure sensor. Using the intranasal cannula supplied with it, the airflow through the nose can be measured and the rhythm and depth of breaths can be determined.
