Guide to Home Medical Devices and Their Supplies

Home medical devices help monitor some health indicators between doctor visits but do not replace medical diagnosis.

Thermometers

Digital thermometers are common in homes because they are safe and quick to read. Ear thermometers give readings in seconds, but accuracy depends on inserting the tip as the device manual explains, and earwax may affect it. Use the same device and method each time to track temperature accurately.

For infants especially, see a doctor if a baby under three months has a raised temperature, or if concerning symptoms such as marked lethargy or breathing difficulty appear.

Blood-Pressure Monitors

The American Heart Association recommends upper-arm cuff monitors, checking that the cuff fits the arm circumference. For a reliable reading:

  • Avoid coffee, smoking and exercise for about half an hour beforehand.
  • Rest seated for five minutes with your back supported and feet on the floor, uncrossed.
  • Place the cuff directly on arm skin rather than clothing, supporting the arm at heart level.
  • Take two or three readings a minute apart and record them at the same time daily to show the doctor.

Home Glucose Testing

Glucose testing relies on three elements: a meter, compatible strips, and a lancing pen with lancets. Crucially, strips work only with their specified meter, so check your meter's name before buying. Wash hands with soap and water and dry before pricking, as food or sugar residue on fingers may raise readings. Keep strips in their closed container and do not use after expiry.

Use a new lancet each time, never share a lancing pen, and dispose of used lancets in a rigid, closed container.

Pulse Oximeters

This device estimates blood oxygen saturation from a fingertip. The US FDA warns that poor circulation, cold extremities and nail polish may affect accuracy. It recommends avoiding reliance on the device alone, monitoring symptoms and contacting a doctor if they worsen.

Weighing Scales

For accurate tracking, weigh yourself at the same time of day on a hard, level surface.

Supports and Bandages

Supports help support joints and limit movement during activity. Size is the main consideration: measure joint circumference and compare it with the pack's size chart. An overly tight support may restrict circulation; a loose one will not function properly. Remove immediately if numbness, coldness or blue colour appears.

Compression Stockings

Compression stockings vary in pressure and length. Their use for circulatory problems should follow a doctor's guidance on the appropriate pressure.

General Advice for Home Devices

  • Read the entire manual and keep it with the device.
  • Replace batteries when a low-battery warning appears, as they may affect readings.
  • Record readings with dates and times, and take the device to the doctor to compare with clinic equipment.
  • Do not change medicine doses based on a home reading without consulting a doctor.
