M523 Siêu âm Doppler theo dõi nhịp tim của thai nhi, một thiết bị phát hiện nhịp tim của thai nhi thông qua nguyên tắc siêu âm Doppler, thuộc về thiết bị y tế loại II.
A fetal heart rate monitor employs ultrasound to spot and log the baby’s heartbeat. This tool aids parents and doctors in evaluating fetal well-being. Home handheld Dopplers offer portability and ease of use. Meanwhile, professional monitors in hospitals deliver ongoing monitoring and contraction logging. When selecting a device, focus on strong sensitivity and precision. This matters most for early spotting at 10–12 weeks.
Put ultrasound gel on your belly. Then, lie down in a calm spot. Next, gently slide the probe over the pubic bone area. Keep moving it slowly until the heartbeat sounds clear.
Tune in for a regular beat between 120–160 bpm. This rate beats quicker than the mother’s pulse. If your device allows, note down the readings for records.
Brief, occasional sessions last no more than 5 minutes each day. Such use seems safe. Yet, steer clear of too much exposure.
Expert fetal monitors show contraction strength and timing. They also display heart rate shifts. This info helps gauge labor advancement. Keep in mind that home Doppler sessions cannot take the place of routine prenatal visits.
