Laerdal -Model Moyo -Fetal Heartrate Monitor

Timely and accurate monitoring
A 9-crystal sensor accurately detects the fetal heart rate within seconds without needing to know the baby’s position. Dual electrodes differentiate the maternal from the fetal heart rate which differs from a regular doppler. Moyo can be used continuously or intermittently.

Better response to abnormalities during labor
Early detection of abnormal Fetal heartrate (FHR) guides decision-making and helps health workers to act quickly. A 30-minute histogram displays the FHR, and audio-visual alarm is activated if abnormal FHR is detected.

Confident health workers and happy mothers
Moyo is lightweight and portable — it can monitor continuously, even while the mother is moving around. It gives a longer heart rate history that informs health workers of the situation and eases the workload without interrupting existing routines.
