Revolutionary Hilo Band Detects Dangerous Blood Pressure Levels Early!

High blood pressure, often termed the “silent killer,” can wreak havoc on vital organs without noticeable symptoms, leading to severe health issues such as heart attacks and strokes. In Germany, approximately 9.8 million individuals between the ages of 30 and 79 suffer from this condition, yet around 30% are unaware of their affliction.

### Introducing the Hilo-Band: A Swiss Innovation

Originally launched in 2021 by the Swiss company Aktiia, the device known as the Hilo-Band has undergone a name change and a significant upgrade in water resistance. It’s now water and dustproof according to the IP68 standard, an improvement from its previous IP33 rating. Although the hardware remains largely unchanged, it has proven its reliability across six studies, as emphasized by the manufacturer. The charging cables, featuring USB-A and Micro-USB connectors, might seem a bit dated, yet they do not detract from the functionality of the device.

### Medical Device Certification

The Hilo-Band is not just another gadget; it is a medical device classified under Class IIa, meaning it has been independently evaluated and approved according to EU regulations for medical devices. This ensures its safety and efficacy for users. However, it’s important to note that while the band provides accurate measurements, it is not a substitute for professional medical diagnosis.

### Everyday Usability and Precision

Unlike traditional arm cuff blood pressure monitors, which can be uncomfortable and impractical for daily use, the Hilo-Band offers a convenient alternative. Smaller and lighter than a typical fitness band, it can be worn all day and night, making continuous monitoring seamless. The device measures blood pressure through a method called photoplethysmography (PPG) which uses light sensors to detect changes in blood flow, calculating blood pressure from these fluctuations. This occurs 20 to 30 times a day during periods of rest.

### Calibration: Key to Accuracy

The calibration of the Hilo-Band is crucial for its accuracy. It utilizes a conventional pump cuff that temporarily stops blood flow in the arm, measuring the changes as pressure is released. This data is then transmitted via Bluetooth to a smartphone app, which helps ensure the band’s readings are accurate. Calibration should ideally be performed at least every four weeks or whenever the device is charged, which is about every 15 days.

### Potential Pitfalls and How to Avoid Them

Incorrect usage can lead to inaccurate readings. Factors such as the wrong body position, a poorly fitted cuff, or recent food or caffeine consumption can affect results. Missteps in the initial setup can lead to continued erroneous readings, as was discovered in a practical test by ntv.de after measurements taken too soon after lunch.

### The App’s Role

The accompanying smartphone app not only guides the calibration process with clear instructions but also assists in maintaining regularity and accuracy in readings. It’s crucial to follow these instructions meticulously to avoid errors.

### Comprehensive Health Monitoring

The app not only tracks daily, weekly, and monthly blood pressure readings but also allows these reports to be exported as PDFs for personal records or to share with a physician. Although integration with other services like Apple Health is limited and typically free only once every four weeks, additional features such as detailed comparisons and medication tracking are available for a monthly fee.

### Cost and Value

At approximately 230 euros, the Hilo-Band is priced reasonably for its features. The most crucial functionalities do not require a subscription, making it an accessible option for those needing to monitor their blood pressure regularly.
