Begin with the doctor's plan
Ask the doctor: which conditions need home readings, what ranges are right for my parent, how often to measure and what readings or symptoms mean "call today" or "call 112". Write the answers on the front of the log. Unplanned monitoring tends to produce worry; planned monitoring produces information. See home health monitoring starter kit and how often to check vitals.
Peak flow meter and breathing checks
For people with asthma, and sometimes COPD, a peak flow meter measures how fast air can be blown out. A fall from the person's usual best can warn of worsening before symptoms, which matters in dusty spells.
- Buy on advice and learn the technique from a nurse or pharmacist; see peak flow meter guide.
- Find the personal best with the doctor, and agree zones (for example, usual, caution, danger) and what to do in each, written down.
- Measure at the same times each day, standing, taking the best of three blows, and record it.
- Dust days: record when construction or traffic dust is heavy, to help the doctor see patterns.
- A written action plan from the doctor, with the use of any prescribed inhalers or nebuliser; see nebuliser buying guide and how to use a nebuliser.
- Emergency: severe breathlessness, difficulty speaking, blue lips or confusion need 112; see when breathlessness is an emergency.
Pulse oximeter: use with care
A pulse oximeter estimates oxygen levels through the fingertip. It may be advised for lung or heart conditions, or after a chest infection.
- Rest for a few minutes, warm the hand, keep still, take off nail polish and read the steady number; see pulse oximeter guide.
- Cool fingers on a cool morning, movement and poor circulation can mislead; a normal number does not rule out illness; see pulse oximeter accuracy limits.
- Ask the doctor what number means action, and see when oxygen saturation is low.
- Do not use it to adjust oxygen or medicines on your own.
Blood pressure monitor
Cool mornings and changes in routine can affect blood pressure.
- An upper-arm monitor with a cuff that fits is the first choice; see bp monitor buying guide, cuff size and bp accuracy and wrist bp monitor pros and cons.
- Technique: rest five minutes, seated, back supported, feet flat, arm at heart level, no talking, two readings a minute apart; see how to measure blood pressure at home.
- When: as the doctor asks; many are asked for morning and evening readings for a week before a review.
- Note the context: a cold morning, a missed night's sleep, a walk before the reading. Compare like with like.
- Dizziness on standing needs a doctor's attention; see dizziness and low blood pressure when standing.
- Never alter medicines because of a number.
Thermometer and weighing scale
A digital thermometer helps decide whether a person who feels unwell has a fever; in older people, infection can cause confusion without a high temperature, so a normal reading does not settle it; see digital thermometer guide and fever in older adults. A scale shows trends: weight loss may signal illness or poor nutrition, and sudden gain may mean fluid in heart or kidney trouble. Weigh at the same time each morning; see weighing scale and weight loss in seniors and daily weights in heart failure.
Glucometer, if there is diabetes
For diabetes, learn the technique from a nurse or pharmacist, check strip dates, and keep strips dry and sealed, particularly in the rainy months; see glucometer buying guide and how to test blood sugar at home. Know the signs of low sugar and what to do; a low reading with drowsiness or confusion is an emergency, so call 112; see diabetes and low sugar emergencies. Inspect feet daily; see diabetic foot care at home.
Hearing and vision: monitoring that is often forgotten
Hearing and eyesight changes are among the most common and most treatable problems of later life, and they affect safety, mood and independence. Rather than devices that measure, these need regular checks: a hearing test, an eye examination and, if advised, hearing aids and spectacles; see hearing and vision checkup schedule, hearing aid buying guide and signs of hearing loss in parents. A hearing aid and TV headphones keep a person engaged at home; see tv headphones guide. Keep a note of when each check is due.
Air quality and comfort
An indoor air-quality reading can help decide when to keep windows shut or to avoid walks, but it does not replace medical advice; see air quality monitor for homes. A room air purifier may help allergic people in the bedroom; see air purifier buying guide.
Keeping a short, useful log
One sheet, one place: date, time, device, reading, symptoms, medicines taken, notes (a dusty day, a cool morning, poor sleep, a trip to the hills). Bring it to appointments, or send a photo before a teleconsultation. Look at trends, not single numbers; see care diary and handover notes. A neighbour or relative who knows the routine can help if your parent lives alone.
Alerts and living alone
A panic pendant, a fall-detection watch or a door sensor can help a person who lives alone or spends hours alone. They help only if worn, charged and answered, and none ensures rescue; see panic pendant buying guide, fall detection watch guide and responding to an alert: who does what. If your parent lives on the outskirts, check how quickly help can reach them; see ambulances and emergency numbers in india. Respect privacy and agreement; see privacy and dignity with monitoring.
Looking after the devices
Replace batteries before they leak; store devices in a dry, cool place away from the bathroom; wipe sensors and cuffs; keep manuals; and ask the clinic to compare your monitor's reading with theirs once a year. During the northeast monsoon, keep devices in sealed boxes with silica. Keep a paper log as a backup when electronics fail.
Matching checks to the season
Dusty dry spells are when breathing checks matter most: peak flow, symptoms and the doctor's plan. The northeast monsoon is the time for temperature checks when anyone feels unwell and for keeping strips and batteries dry. Cool evenings and mornings call for a closer look at blood pressure and joint stiffness. The warm months call for fluid habits and a thermometer within reach. Rather than doing everything all year, tune the routine to the season and to what the doctor has asked for, and write a short note on the log when the routine changes so that the doctor can read the numbers in context.
Avoiding over-monitoring
Agree the schedule with the doctor and keep to it. Too many checks cause anxiety. If a reading surprises you, check technique first: resting, correct position, right cuff, fresh batteries. If it remains concerning or there are symptoms, call the doctor.
When to ask a professional
Ask the doctor what to measure and what to do. A nurse or pharmacist can check your technique. A respiratory nurse or physiotherapist can teach peak flow and breathing techniques. A diabetes educator can teach glucometer use. For senior citizens' information and support, Elderline 14567 is a helpline; check current availability. In an emergency, call 112.

Frequently asked questions
Does my mother need a peak flow meter?
Only if she has asthma, or the doctor advises it for another lung condition. Ask the doctor, and learn the technique.
Why is the oximeter reading lower on cool mornings?
Cold fingers can give poor readings. Warm the hand and check again, and follow the doctor's advice.
What blood pressure reading should make us call?
The doctor sets the numbers for your parent. Ask for them in writing.
Should we monitor every day?
Only as the doctor advises. Daily checks for everything cause anxiety without benefit.
