Product Overview
The BUZUD 30C is an upper-arm oscillometric blood pressure monitor engineered for accurate home-based cardiovascular monitoring. The device employs clinically validated oscillometric measurement technology to determine systolic blood pressure, diastolic blood pressure, and pulse rate from a single inflation-deflation cycle. A large LCD display presents readings with a colour-coded WHO blood pressure classification indicator, enabling patients and caregivers to immediately contextualise results against internationally recognised hypertension staging criteria.
The integrated irregular heartbeat detection (IHB) algorithm identifies arrhythmic pulse patterns during measurement and displays a warning icon when irregular beats are detected. This feature serves as a screening prompt for conditions such as atrial fibrillation, though it is not a diagnostic substitute for electrocardiographic assessment. The 2-user memory function with 99 readings per user supports longitudinal tracking for couples or caregiver-patient pairs sharing a single device. The BUZUD 30C is manufactured under ISO 13485 quality management and holds HSA Singapore approval.

Clinical Indications
- Home blood pressure monitoring for patients with essential hypertension — supports white-coat hypertension differentiation per Singapore MOH Clinical Practice Guidelines on Hypertension
- Self-monitoring for patients on antihypertensive medication — tracking treatment response and medication titration effectiveness
- Screening for irregular heartbeat patterns suggestive of atrial fibrillation in patients aged 65 years and older
- Gestational hypertension and pre-eclampsia monitoring — home BP tracking as adjunct to antenatal clinic visits
- Post-stroke or cardiovascular event secondary prevention — daily BP logging for outpatient follow-up
- Caregiver-assisted blood pressure monitoring in elderly or mobility-impaired patients at home or in nursing facilities
Frequently Asked Questions
How accurate is the BUZUD 30C blood pressure monitor?
The BUZUD 30C provides blood pressure readings with an accuracy of ±3 mmHg for pressure and ±5% for pulse rate, meeting the requirements of ISO 81060-2 for non-invasive sphygmomanometers. For optimal accuracy, patients should sit with feet flat on the floor, back supported, arm at heart level, and rest for 5 minutes before measurement, as recommended by the Singapore Heart Foundation.
What does the irregular heartbeat detection (IHB) feature indicate?
The IHB feature detects irregular pulse intervals during the oscillometric measurement cycle. When triggered, an IHB icon appears on the display, suggesting the presence of arrhythmic beats. This serves as a screening prompt and does not constitute a clinical diagnosis. Patients with persistent IHB alerts should consult a cardiologist for electrocardiographic (ECG) evaluation to assess for conditions such as atrial fibrillation.
Is the BUZUD 30C approved for medical use in Singapore?
Yes. The BUZUD 30C is registered with the Singapore Health Sciences Authority (HSA) as a Class II medical device. It also holds CE marking under EU MDR 2017/745 and is manufactured under ISO 13485 quality management standards. The device is available without prescription for home use.
What cuff size does the BUZUD 30C accommodate?
The included cuff accommodates arm circumferences from 22 cm to 42 cm, covering standard adult through large adult sizes. Using the correct cuff size is clinically important — a cuff that is too small will overestimate blood pressure, while a cuff that is too large will underestimate readings. Patients should measure their mid-upper arm circumference to confirm cuff fit.
How does the 2-user memory function work?
The BUZUD 30C stores up to 99 date-and-time-stamped readings for each of 2 registered users, selected via a user toggle button before measurement. This enables two individuals sharing the device to maintain separate longitudinal BP logs, facilitating trend review during clinic consultations or telemedicine appointments.
