Aidlab’s sensors measure your heart’s ECG, respiration rate, attitude or skin temperature every time you use it. The sampling rate and resolution for some signals is presented as follows:
|Signal Source||Sampling Rate||Sampling Resolution|
|1-Lead ECG Sensor||250 Hz (configurable)||24-bit|
|Respiration Sensor||62.5 Hz||24-bit|
|9-Axis Motion Sensor||50 Hz per axis (configurable)||16-bit|
|Infrared Skin Temperature Sensor||0.1 Hz||10-bit|
Aidlab’s ECG and respiration monitor tracks the electric work of the heart and lungs. The respiratory rate is determined by Aidlab device by using the method of transthoracic impedance measurement. The chest has a basic electrical impedance (approximately 500 Ω) for a high frequency (64 kHz) test signal. When lung volume changes due to breathing, the impedance varies slightly from 0.2 to 5 Ω (peak-to-peak). By measuring and analyzing them we are able to determine the respiratory rate. Aidlab is able to detect impedance changes of ± 32 Ohms with a resolution of 16 bits.
These precise measurements can be influenced by several external conditions that you should consider when starting a measurement.
