Patient Monitoring System Surgeries are taxing, complicated business. And precision is the key word. There is no scope for errors and that applies to pre- and post-surgical care too. Data shows that most deaths occurring due to a surgical intervention happen during the post-operative phase rather than during surgery. There are several reasons for this, including the inability of healthcare institutions to constantly monitor post-operative deterioration as well as patients’ inability to visit the healthcare center for post-operative followups.
