In this sense, ambulatory means capable of providing care for patients who are able to walk and do not require hospitalization. Examples of such facilities include outpatient clinics or emergency departments that provide quick treatment and release patients the same day.
Ambulatory can also refer to a type of medical device, such as an ambulatory blood pressure monitor, which is designed to be worn by a patient for an extended period of time in order to continuously measure their blood pressure without having to visit a doctor's office or hospital. In this context, the term means capable of monitoring and recording data over an extended period while the patient goes about their normal activities.
Overall, ambulatory refers to something that is able to move around on its own, whether it be a medical facility, equipment, or device.
