Researchers at the University of Michigan have demonstrated that patients can use remote ultrasound devices to complete biophysical profiles (BPPs) in high‑risk pregnancies, according to a pilot study presented by lead investigator Alex F. Peahl, MD, MSc. The finding marks a shift from the traditional model, which requires a clinician to operate the ultrasound probe in person.
Study design and key results
The pilot enrolled a small cohort of pregnant women identified as high‑risk based on medical history and obstetric complications. Participants received a handheld ultrasound device that transmitted images to a secure platform, allowing clinicians to assess fetal heart rate, movement, tone, breathing motions, and amniotic fluid volume remotely. They noted that the protocol required a brief training session, after which most participants could operate the device independently.
Implications for prenatal care
If the approach proves scalable, it could reduce the need for frequent in‑person visits, particularly for women living in areas with limited access to obstetric services. The study’s authors suggest that remote BPPs might be integrated into existing telemedicine frameworks, complementing routine prenatal appointments and providing a safety net for those at raised risk of complications.

Critics caution that broader implementation will depend on reliable broadband access and the ability of health systems to interpret the transmitted data promptly.
Nevertheless, the authors argue that the technology could help close gaps in prenatal care delivery, especially in “maternity desert” regions where on‑site services are scarce. By enabling patients to conduct essential monitoring at home, the method may alleviate pressure on overburdened clinics and allow clinicians to focus on cases that truly require in‑person evaluation.
From a broader perspective, the move toward patient‑operated diagnostics reflects a trend in healthcare to give individuals tools once limited to clinical settings. While the study is early‑stage, it signals a potential pathway for expanding access and reducing disparities in maternal health outcomes.

The next phase will involve a larger, more diverse sample size and a comparison of outcomes between remote and traditional BPPs. Researchers also plan to assess long‑term maternal and fetal health metrics to determine whether the remote approach influences rates of preterm birth, stillbirth, or other adverse events.
Hospital administrators interested in adopting the system will need to evaluate infrastructure requirements, staff training, and workflow integration. The study authors have made the protocol and training materials available to other institutions willing to replicate the pilot.
