Stethoscope apps turn smartphones into heart rate monitors, recording vital signs and allowing users to email them to doctors. They work by using the microphone in smartphones and can be used with special stethoscope peripherals for more efficient sound transfer.
A stethoscope app is a downloadable program that can turn a smartphone into a heart rate monitor in situations where a traditional stethoscope isn’t available. Some of these applications are designed to use your smartphone’s built-in microphone, while others may use a modified stethoscope device. In addition to transmitting the sound of your heartbeat or lungs to your headphones, these applications typically also record your heartbeat and other vital signs. This allows a person to record their vitals and then email them to a doctor. Regulations may preclude a stethoscope app from being marketed for medical use since smartphones lack a medical device classification, but these programs can still be useful diagnostic tools in a variety of circumstances.
Apps are small programs designed to run primarily on smartphones and other portable devices. These programs can usually be downloaded directly to a smartphone or other device or transferred from a traditional computer. Each platform has a wide variety of different apps in categories such as productivity, content access, and entertainment. Some of these programs, such as stethoscope apps, can simulate the functionality of other devices or technologies.
To work, a stethoscope app depends on the microphone in each smartphone. It is the presence of these microphones, together with the computing power of modern smartphones, which has allowed these apps to be developed. The microphone needs to be pressed firmly to a person’s chest in just the right place so that they are able to pick up a heartbeat or the sound of lungs breathing. It can take doctors a while to learn the proper way to use a stethoscope, and proper positioning of a smartphone when using a stethoscope app is no different.
After the microphone is placed in the correct position, a stethoscope app can record audio input and also stream it to a headset. This can allow someone to listen to a real-time heartbeat while also recording heartbeat data for later analysis. Depending on the app, a visual recording of your heart rate may also be displayed during use.
Stethoscope apps are typically designed to work with built-in smartphone microphones, although some can also be used with special stethoscope peripherals. This type of peripheral typically consists of a modified stethoscope that attaches to the phone and connects the tube directly to the face of the built-in microphone. Since stethoscopes typically have a diaphragm tip for low frequency sounds and a hollow bell for high frequencies, this can result in more efficient sound transfer.
