Minute Volume Testers (MVTs) are used to measure the amount of air that a person inhales and exhales in a minute. They are used to measure the lung capacity of a person and to diagnose potential respiratory issues. MVTs are also used to measure the effectiveness of a person's breathing treatments.
MVTs come in a variety of sizes and configurations, ranging from simple hand-held devices to more complex computer-controlled systems. The price range for MVTs varies depending on the size and complexity of the device. Hand-held devices can range from $50 to $200, while computer-controlled systems can range from $500 to $10,000.
There are a number of manufacturers that produce MVTs, such as Respironics, CareFusion, Philips, and Welch Allyn. Each manufacturer offers a range of devices to meet the needs of different users and budgets.
