There are many different types of telehealth available in the modern medical industry. Each form of telehealth has its separate uses and advantages. These methods can also be used in combination to provide comprehensive care. The four main categories of telehealth are: Live video conferencing - Live video conferencing, the most popular form of telehealth, is exactly what it sounds like: a real-time, two-way video conference between a patient and their healthcare provider. Store-and-forward - In this process, medical information is securely sent from one healthcare provider to another for consultation or diagnosis purposes. Remote patient monitoring (RPM) - By utilizing technology, remote patient monitoring allows physicians to keep an eye on a patient's vital signs like blood pressure, heart rate, or blood sugar levels remotely. Mobile health (mHealth) - Mobile health refers to the use of portable electronic devices, such as smartphones or tablets, to access healthcare services.
