🩺 Monitoring your health at home with aspergillosis

Many people with aspergillosis (ABPA, CPA, SAFS, aspergillus bronchitis) now use home devices such as pulse oximeters, blood pressure monitors, and thermometers. These are very useful tools — but only if you know how to take reliable measurements and when to act on them.

⚠️ Important: These devices are only guides. If you feel unwell, worsening, or unsafe — seek help, even if the numbers look “normal.” How you feel is always more important than a single reading.

This guide explains:

1. ✅ How to measure correctly

2. 🟢 When to relax, 🟠 when to monitor, 🔴 when to seek help

3. ⚠️ What’s different if you have other health conditions

📏 How to take reliable measurements

🌡 Temperature

• Use a digital thermometer (ear, mouth, or underarm).

• Take your temperature at the same time each day when well, to learn your baseline.

• Avoid measuring straight after a hot drink, bath, or exercise.

• Always use the same device and method for consistency.

• ⚠️ Normal isn’t the same for everyone:

  • Typical range is 36.1–37.2 °C.

  • Some people naturally run a little “cooler” or “warmer.”

  • Temperature changes with time of day, age, hormones, and medicines (e.g. steroids, paracetamol).

  • Your personal baseline is most important.

💨 Oxygen saturation (SpO₂)

• Sit quietly and rest for 5 minutes before checking.

• Warm your hands — cold fingers reduce accuracy.

• Remove nail polish, gel nails, or false nails.

• Place the oximeter on your index or middle finger.

• Keep your hand still, relaxed, and at heart level.

• Wait 30–60 seconds until numbers settle, then record both SpO₂ and pulse.

❤️ Pulse rate

• Normally shown on your oximeter.

• Measure when sitting calmly.

• If irregular, double-check manually by counting your pulse at the wrist or neck for 30 seconds ×2.

• Record alongside oxygen reading.

🔹 Blood pressure (BP)

• Rest for 5 minutes before measuring.

• Use the same arm each time (usually left).

• Keep your arm supported at heart level.

• Sit with feet flat on the floor, legs uncrossed.

• Avoid caffeine, smoking, or exercise for 30 minutes before.

• Take two readings, 1–2 minutes apart, and record the average.

📝 Recording results

• Note date, time, reading, and how you feel.

• Keep a diary or use an app to spot trends over time.

• Share with your GP or specialist, especially if you reach “amber” or “red” zones.

📊 When to seek help — traffic light system

⚠️ Don’t rely on numbers alone. If you feel unwell, dizzy, very breathless, confused, or unsafe, seek medical help — even if your readings are in the “green” zone.

🌡 Temperature

• Green (OK): Within your baseline range.

• Amber (monitor/GP): ≥37.5 °C repeatedly, or ≥1 °C above your baseline.

• Red (urgent help): ≥38 °C once with feeling unwell; any fever with severe breathlessness, chest pain, or confusion.

💨 Oxygen saturation (SpO₂)

• Green (OK): 93–100% (or your personal baseline).

• Amber (monitor/GP): Drop of ≥3% from normal; persistent 89–92% at rest; dips after mild exertion that recover slowly.

• Red (urgent help): ≤88% at rest, or sudden fall with confusion, blue lips/fingers, severe breathlessness.

❤️ Pulse rate

• Green (OK): 60–100 bpm at rest, regular.

• Amber (monitor/GP): >100 but <120 bpm; <50 bpm with fatigue/dizziness; irregular pulse.

• Red (urgent help): >120 bpm at rest; chest pain, collapse, or fainting.

🔹 Blood pressure (BP)

• Green (OK): 100/60 – 140/90 (unless advised otherwise).

• Amber (monitor/GP): Systolic >150 or <95; diastolic >95 or <60 on repeated readings.

• Red (urgent help): ≥180/110, or systolic <80 with dizziness, fainting, or collapse.

⚠️ Comorbidities: special considerations

If you have other health conditions, your safe ranges may be different:

• COPD or severe chronic lung disease → Oxygen targets are usually 88–92% (not higher).

• Heart disease or pulmonary hypertension → Leg swelling + falling oxygen may need urgent review.

• Atrial fibrillation / irregular heart rhythm → Oximeters may give unreliable pulse readings. Confirm with your GP or specialist.

• Diabetes or thyroid problems → Can affect pulse rate and blood pressure; your “green” zone may differ.

• Kidney disease, diabetes, cardiovascular disease → Stricter BP targets may apply (often <130/80).

• Older age or steroid/immune-suppressing treatment → You may not get a high fever with infection. Even a small rise above your baseline could be important.

👉 Always ask your clinician:

• “What’s my personal safe oxygen range?”

• “What blood pressure or pulse numbers should trigger a call for me?”

⚠️ Other warning signs to act on

• Sudden increase in sputum (more volume, colour change, or blood-streaked)

• Fever with worsening cough or breathlessness

• Rapid swelling of legs, ankles, or abdomen

• New confusion, drowsiness, or severe fatigue

---

🟢 AMBER RED system

• Green: Stay calm, record readings.

• Amber: If new or persisting >24–48 hours, contact your GP or specialist.

• Red: Seek urgent medical help (999 / A&E).

✅ Key message:
Home monitors are helpful, but they don’t replace how you feel. Always act on symptoms first — numbers are just part of the picture. If in doubt, seek medical advice.
