App that tracks blood loss during pregnancy

Multiple births and high blood pressure during pregnancy can add to a mother’s risk during delivery. First-time mom, Diana Romano loves spending every moment possible with ten-month old, Leo. Romano had a normal, healthy pregnancy, staying on the job as a doctor until right before Leo was due.

Romano says, “When I went to my 39 week visit I was diagnosed with high blood pressure, so they decided to bring me in that night to be induced.” 

Romano had a smooth delivery with no complications. She said that’s the expectation as most women go into the delivery room.

She continues, “The majority of the time things go beautifully, but sometimes things can get scary.” 

Three percent of all women experience a dangerous hemorrhage during or after labor and delivery. It’s not always easy to tell if a woman is in danger.

Dr. Daniel Katz, Obstetric Anesthesiologist, Mount Sinai, explains, “The traditional way of monitoring blood loss is done by visual inspection.  Meaning we essentially look at the saturated pads and the operative field and make an estimate with our best guess what the blood loss is.” 

Now a cutting edge system called the Triton is taking the guess work out by using an app to analyze the amount of blood on surgical sponges and equipment. Doctors or nurses calibrate the system using a barcode. Then they hold up sponges and pads in front of the computer or Ipad camera.

Dr. Katz continues, “Tt will take pictures of surgical sponges and canisters and measure how much hemoglobin is on them.” 

The system tallies how much blood is lost. Doctors decide in real time if a patient needs additional treatment or even a transfusion. It’s a digital eye that Dr. Katz says helps even the most experienced obstetrician and their patients.

Dr. Katz says for anything that can’t be scanned by the app, they use a Bluetooth-enabled smart scale.

If a doctor types in the surgical tools that are being weighed, the computer can calculate blood loss that way.
