Electrocardiogram (ECG) and and blood oxygen (SpO2) measurements
What is an ECG?
- ECG, or electrocardiogram, is the graphical representation of the electrical activity of the heart.
- With each heartbeat, an electrical wave travels through your heart. This wave causes your heart to contract and pump blood.
- In a doctor's office, a standard 12-lead ECG is usually taken. This 12-lead ECG records electrical signals from different angles in the heart to produce
twelve different waveforms. The device measures a waveform similar to one of those twelve waveforms. This configuration is known as single-lead ECG.
- A single-lead ECG is able to provide information about heart rate and heart rhythm and enables classification of Atrial Fibrillation (AFib). However, a
single-lead ECG cannot be used to identify some other conditions, like heart attacks. Single-lead ECGs are often prescribed by doctors for people to take
measurements at home or in hospital sothe doctor can get a better look at the underlying heart rate and rhythm.
Electrocardiogram (ECG) and and blood oxygen (SpO2) measurements
Recording a standalone SpO2 measurement:
Place your index finger on the right electrode. Your finger should cover the full length of the electrode. Your finger contact should be light.
The quality gauge guides you to keep good, light contact throughout the measurement. Try to stay in the green zone.
1. Select SpO2 in the menu screen. Launch the measurement by pressing the button.
2. The recording will last for 15 seconds.
3. The end of the measurement is confirmed by a vibration
What is SpO2 and pulse rate?
- SpO2 stands for peripheral capillary oxygen saturation, an estimate of the amount of usable oxygen in the blood. It is the percentage of oxygenated
hemoglobin compared to the total amount of hemoglobin in the blood.
- Pulse rate is a measure of the number of times your heart beats per minute. The average pulse rate is typically 65 to 100 beats per minute.
