CARDIUS (CZ-800)12 Channel ECG and Spirometer 2 in 1 designed by ZERONE
The electrocardiograph (abbreviated as EKG or ECG) is a device that records surface potentials associated with the electrical activity of the heartbeat. The surface potentials are conducted to the device by metal contacts called electrodes which are fixed to various parts of the body. Usually, the electrodes are attached to the four limbs and over the heart.
What is Spirometry and why it is done:
Spirometry is the most common type of pulmonary function or breathing test. This test measures how much air you can breathe in and out of your lungs, as well as how easily and fast you can the blow the air out of your lungs.
