blood pressure cuff

Wrist cuffs commonly fit about 5.3–8.5 inches. Upper-arm cuffs typically cover roughly 8.6–17 inches; some upper-arm options list narrower ranges (about 8.7–12.6 inches), while many offer wide-range cuffs up to 16–17 inches.

Most home monitors are battery-powered, commonly using AAA or AA alkaline cells. Some listings note batteries are required but not included, and a few models offer both battery and electric (AC) power options.

Most monitors show systolic and diastolic blood pressure plus pulse/heart rate. Many also flag irregular heartbeat, include hypertension or risk indicators, and provide simple averaging (for example, 3‑reading averages).

Memory varies widely. Some monitors store only a dozen or so recent readings, while many upper-arm devices offer two‑user memory banks that hold dozens to a couple hundred readings per user—examples range from about 14 readings up to 250 per user, and some models support around 198 total across two users.

Many monitors include cuff-wrap or cuff‑fit indicators, motion or excessive‑movement detectors, and wrist‑positioning guides to help ensure the cuff is applied and held correctly for accurate measurements.
