Differences between spirometer, MRI, Pulse oximeter, electrocardiogram and blood pressure monitor?

1. Spirometer: A spirometer is a device used to measure lung function by assessing the volume of air that can be inhaled and exhaled. It is commonly used to diagnose and monitor respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis.

2. MRI (Magnetic Resonance Imaging): MRI is a medical imaging technique that uses a magnetic field and radio waves to create detailed images of the body's internal structures. It is commonly used to diagnose and monitor a wide range of medical conditions, including tumors, injuries, and neurological disorders.

3. Pulse oximeter: A pulse oximeter is a device used to measure the oxygen saturation level in the blood. It is commonly used to monitor patients with respiratory or cardiovascular conditions, as well as during surgery or in critical care settings.

4. Electrocardiogram (ECG or EKG): An electrocardiogram is a test that records the electrical activity of the heart. It is commonly used to diagnose and monitor heart conditions such as arrhythmias, heart attacks, and heart failure.

5. Blood pressure monitor: A blood pressure monitor is a device used to measure the pressure of blood flowing through the arteries. It is commonly used to diagnose and monitor hypertension (high blood pressure) and hypotension (low blood pressure), as well as to assess overall cardiovascular health.
