With BUZUD CGM, you can make treatment decisions without relying on a blood glucose (BG) meter.However, until you are fully confident in using the CGM, it's recommended to continue using a meter—especially in special situations or when glucose levels are changing rapidly.Do not rush the transition. It may take days, weeks, or even longer for you to feel comfortable using CGM data to guide treatment decisions.Work closely with your healthcare professional to regularly review your CGM readings and physical symptoms to determine what works best for you.When Can You Use BUZUD CGM for Treatment Decisions?You can use BUZUD CGM data for treatment decisions when you see both a glucose value and a trend steady arrow displayed on the BUZUD app home screen.BUZUD CGM uses arrows to indicate the direction and speed of glucose changes. The meaning of each trend arrow is as follows:When Should You Use a Blood Glucose Meter?When no glucose value or trend arrow appears in the BUZUD appWhen your physical symptoms do not match the CGM reading (e.g., you feel dizzy or sweaty, but CGM shows a normal value)In these cases, use your blood glucose meter and rely on that reading for any treatment decisions.When Should You Watch and Wait?Avoid taking multiple insulin doses too close together (known as "insulin stacking")Wait at least 2 hours between insulin dosesIf a rapid change is shown in the trend arrows, or after a recent dose or meal, it's best to monitor the trend before making further adjustmentsIf you are unsure about a reading or do not feel well, consult your doctor or contact BUZUD support for assistance.
1. BackgroundWith the widespread adoption of Continuous Glucose Monitoring (CGM) systems in diabetes management, their technical limitations have become increasingly evident. A common artifact seen in clinical practice is compression-induced false hypoglycemia, commonly referred to as “compression low.” This typically occurs at night, presenting as low glucose alarms from CGM devices without symptoms or confirmation via capillary blood glucose testing.This white paper aims to systematically analyze the mechanism, brand-specific differences, clinical identification, and management strategies of compression low based on published studies and manufacturer documentation, to help medical professionals enhance their ability to interpret CGM data anomalies.2. Definition and Clinical ManifestationsCompression-induced false hypoglycemia refers to the inaccurate low glucose readings detected by CGM sensors under mechanical pressure (e.g., lying on the sensor during sleep), due to impaired interstitial fluid flow at the sensor site.Common clinical signs include:Sudden drop and rapid recovery patterns on CGM curves during nighttime;Absence of typical hypoglycemia symptoms;Discrepancy between CGM readings and capillary blood glucose values;Sensor readings normalize after pressure is relieved.3. Mechanisms1. Restricted Interstitial Fluid PerfusionCGM sensors measure glucose concentration in interstitial fluid, not directly in blood. External pressure reduces local capillary perfusion and slows interstitial fluid exchange, leading to artificially low readings.2. Extended Lag EffectAfter pressure is relieved, glucose recovery in the interstitial fluid takes time. This physiological lag causes continued falsely low readings even after the compression is gone.3. Probe DisplacementMechanical force may alter the insertion angle or depth of the sensor probe, shifting it to a low-perfusion or non-target area, thus compromising signal reliability.4. Clinical Evidence and FrequencyKey Studies:Mensh BD, 2013, J Diabetes Sci Technol: Demonstrated significantly increased false low risk from sleeping on the sensor.Facchinetti A, 2016, Diabetes Technol Ther: Found that median compression low events lasted ~45 minutes (range 30–70 mins) in Dexcom G4 users, mostly occurring at night.Helton J, 2011: Modeled CGM errors based on interstitial fluid dynamics and first proposed compression-perfusion interplay as a mechanism.Frequency Observations:Nighttime is a high-risk period, especially during prolonged sleep in one position;Sensors worn for longer durations, with poor fixation or improper adhesion, are more prone to this artifact;Most users may encounter 1–3 compression low events during a typical 7-day CGM cycle.5. Brand-Specific DifferencesDexcomOfficial documentation explicitly acknowledges compression lows;Recommends sensor placement in low-pressure areas (e.g., lateral abdomen, back of the upper arm);G6/G7 systems offer faster recovery but cannot completely eliminate the issue.Abbott FreeStyle LibreThe user manual does not explicitly define compression low, but highlights that sensor dislodgement or poor adhesion can cause falsely low readings;Clinical reports indicate Libre 2/3 sensors are more susceptible, especially in lean individuals.Medtronic Guardian SensorAdvises against sensor placement in areas prone to motion or compression;Compression-induced errors may falsely trigger SmartGuard automatic insulin suspension, affecting insulin delivery.Senseonics Eversense (Implantable CGM)As a fully implantable sensor, Eversense is largely immune to external pressure effects;No reported cases of compression lows, making it unique among CGM systems.BUZUD CGMBUZUD uses a subcutaneous sensor structure similar to traditional CGMs, supporting real-time glucose monitoring;Preliminary testing shows improved resistance to compression-related signal artifacts due to enhanced stability and adhesion;Compression lows may still occur; BUZUD advises avoiding sensor placement in areas likely to be compressed during sleep;If abnormal readings occur, users are encouraged to confirm via capillary blood glucose testing.6. Clinical Management RecommendationsIdentification Criteria:CGM curve shows sudden drop with rapid rebound, inconsistent with true hypoglycemia;No symptoms of hypoglycemia present;Strong correlation with sleep position or pressure on the sensor area.Response Strategies:Educate patients to choose sensor sites unlikely to be compressed while lying down;Do not immediately treat CGM-reported lows with carbohydrates—verify with fingerstick first;Label these events in medical records as “compression-induced artifacts” to avoid misdiagnosis or overtreatment;If frequently recurring, reassess adhesion method and device stability, and contact manufacturer if needed;Encourage CGM manufacturers to optimize algorithms that detect compression-related patterns to reduce false alarms.7. ConclusionCompression-induced false hypoglycemia is a CGM-specific artifact that poses challenges to accurate diabetes management. Its relatively frequent occurrence and potential clinical impact necessitate better understanding among healthcare providers.By improving clinical recognition, educating users on proper placement and sleep behavior, and working with device manufacturers to enhance signal processing, the burden of this artifact on clinical decision-making can be significantly reduced.It is recommended that all diabetes care teams include this topic in CGM interpretation training to strengthen understanding of device limitations and improve patient outcomes.
Time in Range (TIR) refers to the percentage of time that a person's glucose levels stay within a defined target range. It is a key indicator for assessing the quality of glucose control, typically based on data collected from continuous glucose monitoring (CGM) devices.TIR reflects the proportion of time that glucose levels fall into three general categories:Target Range: 3.9–10.0 mmol/LVery High: Above 13.9 mmol/LVery Low: Below 3.0 mmol/LThese thresholds are based on international clinical consensus, but doctors may adjust them according to individual needs.Why is TIR important?TIR provides a more dynamic view of daily glucose control than A1C alone.Maintaining a higher TIR (e.g., above 70%) is associated with reduced risk of complications.TIR is useful for evaluating treatment effectiveness, medication response, or lifestyle changes.TIR is becoming a standard metric in diabetes management and supports more personalized, real-time care.
The Ambulatory Glucose Profile (AGP) is a standardized glucose report developed and licensed by the International Diabetes Center (IDC).The AGP report compiles continuous glucose monitoring (CGM) data over a period of time to provide a comprehensive overview of glucose trends, offering a big-picture view of diabetes management.It is important to note that the AGP is just one tool for understanding glucose patterns. It should be interpreted in combination with lifestyle, medication use, and other medical information.

What is Continuous Glucose Monitoring (CGM)?BUZUD Continuous Glucose Monitoring (CGM) system continuously tracks your glucose levels throughout the day and night, and automatically alerts you when your glucose goes too high or too low—helping you respond proactively.The CGM system measures glucose at regular intervals every few minutes, 24/7. These readings are translated into dynamic charts that clearly show glucose trends and the rate of change, giving you a comprehensive view of your glucose fluctuations and helping you make more informed lifestyle and treatment decisions.
The BUZUD Continuous Glucose Monitoring (CGM) system tracks your glucose levels continuously throughout the day and night.Here’s how it works:An automatic applicator inserts a very thin sensor wire just beneath the skin.An adhesive patch secures the sensor in place.The sensor continuously measures glucose levels in the interstitial fluid 24/7.A small, reusable transmitter attaches to the sensor and wirelessly sends real-time glucose readings to your compatible smart device (such as a smartphone).Through the BUZUD App, you can view your current glucose levels and historical trends at any time.The app can also be customized to send personalized alerts when your glucose levels go above or below preset thresholds.BUZUD CGM provides continuous, real-time glucose insights, helping you manage your blood sugar more confidently and proactively.
BUZUD CGMs Readings vs. Blood Glucose MetersWhether you're new to BUZUD CGMs or have used it before, it's important to review the product instructions carefully before use. Until you're confident in how BUZUD CGMs performs for you, continue using your blood glucose meter (BG meter) for treatment decisions.Your BG meter will give you one result. If you test again—whether with the same or a different meter—you may get a different value. Meanwhile, your BUZUD CGMs may show a third number. So, how should you interpret these differences?Understanding AccuracyLab-based glucose tests conducted by healthcare professionals are considered more accurate than any at-home device. In clinical studies, both blood glucose meters and BUZUD CGMs are evaluated by comparing their readings to lab results—not to each other.As a result, BUZUD CGMs readings may not match your meter exactly, but they should be close. You can compare them using what’s called the "20 Rule" (also known as the 20/20 rule) to determine how closely they align.What Is the 20 Rule?To apply the 20 Rule:Locate your meter reading in the center column of the chart;The left column (CGMs –) shows the lowest expected CGMs reading;The right column (CGMs +) shows the highest expected CGMs reading.For example, if your meter reading is 5.6 mmol/L (100 mg/dL), then any BUZUD CGMs reading between 4.4 and 6.7 mmol/L (80 to 120 mg/dL) would be considered an acceptable match.Best Practices for Fingerstick TestingTo ensure accurate meter readings:Store your test strips as directed and check expiration dates;Wash your hands with soap and water (not hand sanitizer), dry thoroughly, and then test.Situations That May Cause Temporary MismatchesFirst Day of Sensor Use: Readings from a newly inserted sensor may initially vary more from meter values. Accuracy typically improves within the first 24 hours.Rapid Glucose Changes: During rapid fluctuations, readings may differ because your meter reflects blood glucose levels, while CGMs measure glucose in interstitial fluid, which lags behind slightly. As glucose levels stabilize, readings will better align.Sensor Compression: Pressure on the sensor (e.g., lying on it while sleeping) can affect accuracy. Once the pressure is relieved, readings usually return to normal.When Should You Consider Calibration?Observe your CGMs readings over several hours. If they consistently read higher or lower than your meter and fall outside the 20 Rule, calibration may help.You may also calibrate if your CGMs readings don’t match how you feel, but your meter results do.Calibration GuidelinesBUZUD CGMs does not require routine calibration. Although calibration may bring readings closer to your meter values, it doesn’t always improve accuracy relative to lab standards.If you decide to calibrate:Enter the fingerstick value within 5 minutes of testing;Avoid calibration during a "Sensor self-check" status.How to Manually Use the 20 RuleBUZUD CGMs readings are considered accurate when:If the meter value is ≥ 4.4 mmol/L (80 mg/dL), the CGMs reading is within ±20%;If the meter value is < 4.4 mmol/L (80 mg/dL), the CGMs reading is within ±1.1 mmol/L (20 mg/dL).Important NoteThis information is intended for BUZUD CGMs users. Please consult your healthcare provider or local guidance for specific usage instructions.
BUZUD Continuous Glucose Monitoring systems (CGMs) support manual calibration, but in most cases, calibration is not required for accurate performance. Our systems are designed to provide a seamless experience without the need for fingerstick calibration. Manual calibration is available as an optional feature.When Should You Consider Calibration?If your BUZUD CGM reading differs from a fingerstick blood glucose value by less than 20%, this is considered within the normal range.If the difference falls between 20% and 30%, manual calibration may improve accuracy.Note: Once you initiate manual calibration, the system will continuously adjust future readings based on your input.When Should Calibration Be Avoided?To ensure system stability and avoid potential malfunctions, do not calibrate in the following situations. Incorrect calibration can significantly reduce CGM accuracy and may even result in reading failures or device damage:When the Sensor Is Under PressureIf the sensor site is being compressed by clothing, body position, or external force, glucose values may be temporarily inaccurate. Calibrating under these conditions may cause the system to adjust based on incorrect data, leading to long-term inaccuracy or damage to internal algorithms.During Rapid Glucose ChangesAfter meals, during exercise, or following insulin injections, blood glucose levels may change rapidly. CGM readings have a physiological delay. Calibrating at these times can mislead the system into learning inaccurate trends, potentially causing persistent data distortion or sensor malfunction.When Up or Down Arrows Are DisplayedArrows indicate rapid glucose movement and an unstable state. Calibrating during these moments may result in system errors or device lock-up due to the sensor's inability to reconcile the trend.During Sensor Error MessagesIf the system shows "Sensor self-check" or "No sensor," do not calibrate. The sensor is not in a stable data collection state, and forcing a calibration may corrupt internal calibration parameters or require premature sensor replacement.Frequent or Unnecessary CalibrationBUZUD CGMs are designed with automated calibration mechanisms. Excessive manual input may disrupt internal algorithms, leading to erratic glucose curves, false alerts, or incorrect readings. Only calibrate when absolutely necessary, and preferably under guidance from a healthcare professional.Things to Know Before Calibrating:Wash and dry your hands with soap and water before testing. Avoid alcohol wipes or hand sanitizer, as they may interfere with accuracy.Enter the value within 5 minutes of fingerstick testing to ensure the reading reflects your current glucose level.Only use fingertip blood glucose values. Alternate sites (e.g., forearm) may yield inaccurate results.Acceptable calibration values range from 2.0 to 25.0 mmol/L. Values outside this range will not be accepted.If you receive a "Calibration Failed" message, repeat the fingerstick and try calibrating again.How to Calibrate Your BUZUD CGMUsing the BUZUD App (for models that support calibration):Open the BUZUD App and go to the CGM page.Tap the "Calibrate" button on the screen.Enter the blood glucose value from your fingertip test and follow the on-screen instructions to complete calibration.BUZUD CGMs are built to deliver a convenient and accurate glucose monitoring experience. Unless necessary, we recommend relying on automatic sensor readings without frequent manual adjustments. For any questions, please contact BUZUD support or consult a healthcare professional.
The BUZUD CGM system has not been tested under defibrillation conditions or in patients using pacemakers or implantable cardioverter defibrillators (ICDs). Currently, there is no data to determine whether an electrical shock would affect CGM performance or reliability.If a patient receives a shock, it is recommended to closely observe the performance of the BUZUD CGM. If the CGM readings do not match symptoms or expectations, please perform a blood glucose (BG) check using a standard fingerstick method.Additionally, the pacemaker manufacturer should be consulted to confirm whether the device has been tested for resistance to Bluetooth signals in the 2.4 GHz frequency range, and to see if any specific recommendations or precautions are provided.⚠️ Always follow professional medical advice and the guidance of your device manufacturer when using electronic medical devices together.
Compared to traditional Self-Monitoring of Blood Glucose (SMBG), BUZUD CGM (Continuous Glucose Monitoring) systems provide much more comprehensive and continuous glucose data.For BUZUD CGM users, accuracy is evaluated based on comparisons with traditional fingerstick blood glucose values. However, it’s important to note that fingerstick testing can be affected by various factors such as timing, technique, and consistency during blood collection.In summary, while occasional differences between BUZUD CGM and meter readings may occur, BUZUD CGM offers real-time glucose trends and continuous monitoring, empowering users to manage their glucose more effectively and make informed decisions throughout the day.

BUZUD CGM users aged 2 and above can choose from the following sensor insertion sites:Abdomen or back of the upper armWe recommend choosing areas with a good amount of subcutaneous fat and minimal muscle movement to ensure comfort and stable glucose monitoring.Helpful TipsAvoid areas near the navel, bony prominences, or areas with skin folds.Rotate insertion sites with each sensor change to minimize the risk of skin irritation.
1. Select Implantation SiteThe image shows choosing the back of the upper arm as the implantation site for the CGM device.2. Disinfect the Skin SurfaceUse an alcohol wipe or disinfectant cloth to clean the surface of the skin on the back of the upper arm to ensure it is sanitized.3. Prepare the Insertion DeviceRemove the CGM insertion device from its packaging, open it as shown, and inspect the device to ensure it's ready for use.4. Position the Insertion DevicePlace the insertion device firmly against the skin, ensuring the device is aligned with the selected implantation site.5. Initiate InsertionPress the button on top of the insertion device to activate it, inserting the sensor beneath the skin.6. Remove the Insertion DeviceAfter insertion, remove the insertion device, leaving the sensor properly installed on the skin.
One possible reason is that the sensor may be under pressure while you're sleeping, which can cause the BUZUD CGM to report lower glucose readings. Once the pressure is relieved, the readings usually return to values that are closer to your fingerstick results.To avoid this issue, choose a sensor site that is less likely to be bumped, compressed, or laid on during sleep.If the readings do not return to normal after relieving the pressure, consider doing a calibration when your blood glucose trend is stable to help the system regain accuracy.
To ensure you continue receiving accurate and uninterrupted CGM data on your compatible smart device, please review the following best practices:Bluetooth ConnectionsMinimize Bluetooth Pairings: Keep the number of active Bluetooth connections on your phone to a minimum.Unpair Old Devices: After you stop using a BUZUD transmitter, unpair it from your phone’s Bluetooth settings.

什么是自动校准？自动校准是一项简化 CGM 校准流程的功能。当你使用配对的血糖仪完成血糖测量后，App 会自动获取测量结果并用于校准你的 CGM 传感器，无需手动输入。CGM 的校准算法没有任何改变。自动校准只是改变了血糖值传递给 CGM 的方式：从你手动输入，变为 App 直接从血糖仪接收。开始使用如何开启自动校准？打开 App，进入 CGM 设置。将自动校准开关切换为开启状态。开启后，下次你使用配对的血糖仪进行血糖测量时，App 将自动使用测量结果校准你的 CGM。如何关闭自动校准？按照上述相同步骤，将自动校准开关切换为关闭状态即可。关闭后将恢复标准的手动校准流程。你可以随时在自动和手动之间切换。需要重新配对血糖仪吗？不需要。如果你的血糖仪已经与 App 配对，自动校准会直接使用现有的配对连接。如果你尚未配对血糖仪，请前往设置 > 设备，按照屏幕指引完成配对。工作原理做血糖测量时会发生什么？当自动校准开启时：你像往常一样使用血糖仪进行指尖采血测量。血糖仪通过蓝牙将测量结果发送给 App。App 检查该数值是否有效。如果一切正常，App 自动完成 CGM 校准。你会收到一条通知，确认校准已完成以及使用的血糖值。整个过程在血糖仪完成测量后几秒钟内自动完成。App 会修改血糖值吗？不会。血糖仪测量的原始数值就是用于校准的数值。App 不会对读数进行任何修改、四舍五入或调整。还能手动校准吗？可以。无论自动校准是开启还是关闭，手动校准始终可用。你可以通过校准页面进入手动校准，也可以在任何失败通知中点击"手动校准"。怎么知道校准已经发生了？你会看到一条通知，例如："校准：自动校准完成。120 mg/dL，来自 [你的血糖仪名称]。"你也可以查看 App 主页的校准状态，它会显示上次校准的时间。点击校准状态指示器可以打开完整的校准历史记录。故障排查做了血糖测量但没有触发自动校准可能有以下几种原因：蓝牙连接问题 — 血糖仪和手机之间的蓝牙连接可能已断开。请确认血糖仪在手机附近（通常几米范围内），并且手机的蓝牙功能已开启。将血糖仪放在手机旁边，重新进行一次测量。自动校准未开启 — 请检查设置 > 校准 > 自动校准是否已开启。App 未在运行 — App 需要处于运行状态（可以在后台运行）才能接收血糖仪的数据。请打开 App 后重试。最小校准间隔 — 如果你最近刚完成过校准，App 可能会延迟下一次校准以保护精度。请等待冷却期过后再试。在此期间，你随时可以使用手动校准。收到"血糖变化过快"的通知这表示你进行血糖测量时，血糖水平正在快速上升或下降。在血糖快速变化时，指尖毛细血管血糖（血糖仪测量的值）和组织间液葡萄糖（CGM 测量的值）之间可能存在自然的时间差，这会降低校准质量。处理方法： 等到血糖水平较为平稳时再进行测量 — 理想情况下，CGM 的趋势箭头显示为平稳或接近平稳。然后重新进行一次血糖测量，App 会再次尝试自动校准。如果不想等待，也可以选择手动校准。收到"校准数据已过期"的通知这表示血糖仪完成测量到数据到达 App 之间存在延迟。这通常发生在蓝牙短暂断开后重新连接，血糖仪发送了一个较旧的测量结果。处理方法： 确保血糖仪在手机附近且蓝牙已连接，然后重新进行一次血糖测量。App 要求数据必须是近期的（几分钟以内），以确保校准精度。收到"未识别的血糖仪"的通知这表示 App 收到了来自未注册到你账户的血糖仪的数据。这可能发生在附近有其他血糖仪的情况下，或者你正在使用尚未配对的新血糖仪。处理方法： 前往设置 > 设备，确认你的血糖仪已列出并完成配对。如果你有新的血糖仪，请按照屏幕指引完成注册。App 只会接受来自已注册血糖仪的校准数据。收到"数据完整性校验失败"的通知这表示从血糖仪接收的数据不完整或无法通过验证。这通常是蓝牙在数据传输过程中出现短暂中断导致的。处理方法： 这通常是一次性的情况。请重新进行一次血糖测量。如果问题持续出现，请尝试在设置 > 设备中取消配对后重新配对你的血糖仪。收到"数值超出有效范围"的通知这表示从血糖仪接收的血糖值超出了校准接受的范围（通常为 20 至 600 mg/dL）。这可能表示血糖仪读数异常。处理方法： 请先确认血糖仪上的读数。如果数值看起来正确且你认为应该用于校准，可以通过手动校准页面手动输入。如果数值看起来不正确，请使用新的试纸条和充足的血样重新测量。数值被接受但校准仍然失败在少数情况下，即使血糖值本身有效，CGM 也可能拒绝校准。这可能发生在 CGM 传感器检测到内部条件不允许当前进行校准的情况下。处理方法： 请等待片刻后重试，可以通过重新测量血糖（自动校准）或手动校准来完成。如果校准持续失败，请参阅 CGM 故障排查指南或联系客服。自动校准后 CGM 读数似乎不准确如果你发现自动校准后 CGM 的读数与预期不符：查看校准历史记录，确认使用了什么数值。在主页点击校准状态即可打开记录。如果数值看起来不正确，请重新进行血糖测量并再次校准（自动或手动均可）。确保在血糖平稳时进行校准，避免在快速上升或下降期间校准。如果使用确认正确的血糖值重新校准后读数仍然不准确，请联系客服。常见问题自动校准会改变 CGM 的准确性吗？不会。自动校准使用的校准算法与手动校准完全相同。唯一的区别是血糖值如何传递给 App。实际上，自动校准可能有助于提高准确性，因为它消除了手动输入时打错数值的可能性。自动校准支持所有血糖仪吗？自动校准适用于与 App 兼容的血糖仪型号。你的血糖仪必须在 App 中完成配对和注册。前往设置 > 设备查看兼容的血糖仪列表。别人的血糖仪会意外校准我的 CGM 吗？不会。App 只接受来自你账户中已注册的特定血糖仪的校准数据。即使附近有其他血糖仪，它们的数据也会被忽略。自动校准会增加耗电量吗？对电池续航的影响非常小。App 使用的是与血糖仪通信时已经建立的蓝牙连接，不需要额外的后台扫描。每次自动校准都会收到通知吗？是的。无论自动校准成功还是失败，你都会收到通知。成功通知会在几秒后自动收起，但仍可在通知中心查看。失败通知会保持显示，直到你确认。如果在开会或睡觉时没看到通知怎么办？App 主页始终显示当前的校准状态，包括上次校准的时间。如果校准失败且你未确认通知，App 会发送后续提醒。如果校准到期未完成，校准状态指示器会变为警告状态。可以撤销一次自动校准吗？如果你认为某次自动校准使用了错误的数值，可以使用正确的血糖值重新进行校准（自动或手动均可）。新的校准会覆盖之前的校准。自动校准默认是开启的吗？是的，自动校准默认开启。你可以随时在关闭
