Heart Fluid Check

v164

Your name

Good morning — let’s check your fluid

Why the doctor says take an extra water pill

Swollen feet are a late sign. Fluid often builds in the body first — weight up, tighter shoes, needing extra pillows, shorter breath. Your clinician may say: take an extra water pill (loop diuretic) on those days so you don’t wait until ankles are big.

Thank you for choosing Heart Fluid Check. This check helps you catch early fluid signs, then use Reassess to see if symptoms improved. Follow the written plan from your heart team.

As-needed only. Built for when your clinician said take an extra water pill if fluid is building — not for a water pill you’re already prescribed every day on a fixed schedule. Follow the written plan you were given.

Got a past heart report PDF?

Upload it under Heart chart to fill EF and old heart-failure notes from the report.

Today’s vitals, weight, and symptoms

Enter how you are right now. Used with the water-pill check below.

Current vital signs

Set your usual / dry weight in Settings first.

Symptoms (fluid / congestion signs)

Yes = extra fluid may be building. Don’t wait for big swollen feet. A water pill (loop diuretic) helps fluid but does not replace the 4 main heart medicines — guideline-directed medical therapy (GDMT).

Home bottles and discharge medicines

Home bottles and discharge medicines

If you are not using the discharge list, check Need on each medicine you take. Then check Checked after the name, dose, and how often look right. A missing field stays open with a star. Checking it closes that medicine.

Medicines are stored only after you check them against the bottle. Educational use only — not medical advice, not a prescription, and not a duty of care. Follow your treating clinician’s plan. Do not change or stop a medicine because of this app.

Heart chart for the doctor’s office, ER, or clinic.

Upload papers (PDF or photo)

  1. Choose a PDF, or take a photo of the discharge papers.
  2. Wait here until it says Upload successful.
  3. Then check Heart chart. The full file is not stored.

Photo of discharge papers, med list, or after-visit summary — stays on this device. Up to 12 photos.

Past medical history

Diagnoses already on the chart before this heart-failure stay. Upload can fill this from a Past medical history or PMH heading. Edit anything that is wrong. This is not the new heart-failure diagnosis.

2. First symptoms

What first led to the workup that found heart failure? Short of breath, swelling, chest pain, a cold or upper respiratory infection (URI), tiredness, etc.

Workup after those first symptoms

3. Heart ultrasound (echo)

All echo findings in one place — from the heart ultrasound (echocardiogram) report. Manual entry OK.

Suggested from common guideline timing — confirm with your cardiologist. HFrEF often reassess ~3 months after optimizing guideline-directed medical therapy (GDMT) / revascularization when EF remains low; HFpEF — routine serial echo not required if stable; repeat when clinical status changes (optional ~1 year).

4. Labs pertinent to heart failure

Numbers and the date labs were taken only — lipids when available. Type results by hand anytime — PDF extract can fill some of these too.

Lipid panel

5. EKG (electrocardiogram)

Rhythm and key findings from the heart tracing — date if known.

6. Chest X-ray

Short summary of the chest film — date if known.

7. Lungs / fluid in the lungs

Plain-language focus: congestion or fluid in the lungs from the chest film or notes. Separate from ankle swelling.

8. Medicines sent home (discharge prescriptions)

Check each medicine prescribed at discharge. Use Search for brand or generic names.

Heart and fluid medicines (cardiac / diuretic)

i.e. metformin (diabetes), levothyroxine (thyroid), blood pressure pills, inhalers, vitamins, pain medicine.

9. Usual vitals (when steady)

Typical numbers from the past when you felt steady — not today’s check.

Same number as Settings — one source of truth.

10. New heart failure diagnosis (incident HF diagnosis)

When and where heart failure was first named, and what kind — plain words first.

Hospital or clinic name where diagnosed / seen

11. Stent / vessel occlusion — percutaneous coronary intervention (PCI)

Pulled from the report — edit anything that’s wrong.

Where this comes from

For educational use only — not medical advice. Follow your treating clinician’s plan. Informed by the 2022 AHA/ACC/HFSA Heart Failure Guideline and 2024 ACC consensus updates.

Which kind of heart failure?

Two common clinic names (pick what your heart doctor named — you can change this later):

  • Weak pump (HFrEF) — the heart’s squeeze is low (low ejection fraction / EF). Blood doesn’t push out strongly.
  • Stiffer pump (HFpEF) — the squeeze may look OK, but the heart doesn’t fill well between beats. Fluid can still build up.

Left side vs right side is a different idea: left-side problems often show in the lungs (short of breath, needing extra pillows); right-side strain often shows in the legs and belly (swelling). Many people have both. That video is on setup page 2.

The heart-stent video is on setup page 2.

Weak pump (HFrEF) — usual medicines

Check the boxes for medicines you already take. The first four are the usual main heart medicines for a weak pump. Your clinician chooses doses and timing.

Recent days

Each day keeps weight, BP, heart rate, SpO2, symptoms, and whether a water pill was taken. Bring this to your visit if helpful.

Send the saved log the same way as today’s update. Text works on phones; email is better on a computer. You’ll pick who gets it if more than one person is saved.

About

Know your fluid. Know your heart.

About the creator

Hi — I’m Melody Ann Moore, an adult-gerontology acute care nurse practitioner (AGACNP-BC) with a critical care background (CCRN). I’ve spent years at the bedside in ICUs — medical, cardiac, and surgical — caring for people through the scariest days of heart and lung illness. I built Heart Fluid Check for my dad after he was newly diagnosed with heart failure, because I wanted something he (and we) could actually use at home.

Why I made this

Discharge papers are overwhelming. The goal here is simple: know your fluid, know your heart. Weight, symptoms, water pill, and the key tests — echo, labs, EKG, chest X-ray — in plain words, so you can spot fluid building up early and feel steadier between visits.

This is guidance for families — not medical advice. Follow the written plan from the cardiology team.

Rings at this time even if no water pill was logged.

Default 3 hours after you tap “I took my water pill.” Works together with the afternoon time.

Water pill plan

As-needed (PRN extra dose) or every day on a set schedule. Weight watching stays for both.

i.e. Lasix (furosemide), Bumex (bumetanide), Demadex/Soaanz (torsemide), or Edecrin (ethacrynic acid). Sometimes metolazone (Zaroxolyn) is added if fluid is hard to clear.

Your doctor’s plan for extra fluid. Use with your 4 main heart medicines — guideline-directed medical therapy (GDMT) — not instead of them. See Guidelines.

Run setup again walks through the same steps — it does not wipe your saved data.
