Omron M3 Digital Automatic Blood Pressure Monitor (Arm Type)

Details

The Omron M3 is an advanced digital blood pressure monitoring device engineered for professional environments and users requiring detailed, long-term tracking. Its robust design, large, sturdy cuff, and extensive memory capacity make it suitable for continuous, high-frequency use. This monitor provides accurate readings of systolic and diastolic blood pressure, along with pulse rate, serving as an essential tool for managing hypertension and tracking patient progress in clinics and advanced home care settings.

Available Models/Sizes/Variations

The Omron M3 is an automatic Digital Monitor worn on the upper arm.

• Cuff: Includes a Wide Range Cuff (22–42 cm), which is large, sturdy, and suitable for the majority of adult arm sizes.
• Design: Durable build quality, making it recommended for hospital use.
• Memory: Features extensive internal memory for detailed record-keeping.

Main Intended Uses

The Omron M3 is indicated for:

• Professional BP Measurement: Ideal for use in clinics and hospitals for quick, reliable patient screening.
• Chronic Disease Management: Supports detailed tracking of blood pressure trends for patients with severe hypertension.
• Reliable Monitoring: The 22-42 cm cuff ensures a high degree of accuracy across diverse body types.

Localized Benefits: The durable, high-memory capacity is valuable for busy clinics, allowing staff to quickly process and record patient data efficiently during high-volume periods, improving workflow.

Operating Instructions

1. Setup: Insert AA batteries into the monitor unit. Connect the air tube of the cuff securely to the monitor port.
2. Placement: Wrap the Wide Range Cuff securely around the bare upper arm, positioning the cuff’s tube over the brachial artery. The cuff must be level with the heart.
3. Operation: Sit still for 5 minutes, press the START/STOP button. The device will automatically inflate, measure, and display the result.
4. Maintenance: Wipe the monitor and cuff with a soft, dry cloth. Store in the case away from heat and moisture to ensure longevity.

Potential Risks/Adverse Events

• Inaccuracy: Improper cuff placement or movement during measurement is the primary risk, leading to inaccurate readings and potentially poor medical decisions.
• Discomfort: Temporary mild discomfort or pressure sensation may occur during cuff inflation.

Interactions/Compatibility

• Cuffs: Compatible with Omron cuffs that feature the standard connector, primarily the Wide Range Cuff (22-42 cm).
• Medical Conditions: BP readings can be affected by certain medications, arrhythmias, or severe limb injury; consult a doctor for interpretation.

Warnings/Precautions

• Do Not Self-Diagnose: Use the readings for tracking purposes only. Do not stop or adjust medication without a doctor’s instruction.
• Correct Sizing: Always ensure the cuff size matches the arm circumference to prevent highly misleading results. The wide-range cuff minimizes this risk for most adults.

Localized Warnings: Due to potential power fluctuations, avoid using non-certified AC adapters with the device, which could damage the monitor and affect its accuracy, thus compromising patient data.

Quick Device Facts Table

Mechanism of Operation

The Omron M3 utilizes the Oscillometric Method. An air pump inflates the cuff around the upper arm until it occludes the brachial artery. As the pressure is gradually released, the monitor’s pressure sensor detects the tiny pulsations (oscillations) of the arterial wall caused by the blood flowing back into the artery. The device’s internal algorithm uses a complex calculation based on the magnitude and rate of these oscillations to determine the Systolic (peak) and Diastolic (minimum) blood pressure values, which are then displayed digitally. The robust design supports frequent use without compromising accuracy.
