AirStrip, an app that lets doctors use their mobile devices to monitor a hospital patient's vital signs remotely, is one of the many mobile technology startups that is helping to cut health care costs under Obamacare. Here's how it works:

Vitals To Go

This system, developed by AirStrip Technologies in San Antonio, comprises hardware, software, and services, and is FDA approved. When connected to monitoring equipment in the hospital, AirStrip can fetch and display a wide range of patient data, including temperature, blood pressure, fetal heart rhythms, and almost anything else measured at the bedside. It can also provide a patient's medical history, lab results, and allergies. As a result, a team of doctors and nurses scattered in multiple locations can collaborate on treatment decisions, and specialists in other cities can provide a quick consultation.

Outside Diagnosis

Using AirStrip on a smartphone or tablet, a doctor can remotely diagnose a likely heart attack--and phone in orders for immediate and potentially life-saving interventions. That way, the hospital or emergency technician doesn't have to wait for the right doctor to show up to take action, saving precious minutes in a critical situation.

Privacy, Please

AirStrip had to meet tight federal requirements for data security and privacy. No data is ever stored on the remote cell phone or tablet. Encryption and rigorous password protection prevent unauthorized access or interception of the data.
