Start with the documented arm range
Look up the arm-circumference range in the manufacturer manual. A 22–42 cm cuff and a 22–32 cm cuff are different choices even when the monitor names look similar. Use the cuff finder to narrow the listed products by the documented range.
Check what is included
A compatible larger cuff may be available separately. The directory distinguishes manufacturer-listed replacement accessories from the cuff supplied with a monitor; a retailer bundle may differ.
Match the exact model
Read the model code on the box or monitor label. A marketing name such as M2 can cover more than one version. Only use a documented compatibility relationship when choosing a replacement cuff.
See the documented blood pressure monitors & cuffs options or match a cuff by model and size.
