How it works
From daily readings
to a complete kidney picture.
CKD is managed day by day - not just at quarterly appointments. Ziva connects your daily BP, weight, glucose, and medication adherence into one continuous record so you and your nephrologist know what's happening between visits.
1
Tenovi devices ship to your door
A blood pressure cuff, smart weight scale, and pulse oximeter arrive pre-configured. No Wi-Fi setup, no Bluetooth pairing - just turn them on and they transmit automatically via cellular.
2
Take your readings each morning
Blood pressure, weight, and SpO2 - each takes under a minute. Readings sync to Ziva automatically. Isabella logs your medication schedule and tracks each dose throughout the day.
3
Log symptoms and how you feel — you enter these
Isabella prompts you daily: fatigue level, swelling in ankles or legs, shortness of breath, nausea, and any appetite changes. These symptom logs add context to your readings and build a richer picture for your provider.
4
Isabella spots fluid retention patterns
Rising BP combined with rapid weight gain is a reliable early sign of fluid retention. Isabella correlates your daily readings against your personal baseline and alerts you - and your care team - when the pattern emerges.
5
Monthly report shared with your provider
BP trend, weight trajectory, medication adherence, symptom log, and Isabella's observations - ready before every appointment. Supports RPM billing documentation.

Isabella · Today's priority
"Your BP and weight have been rising together for 5 days — that's a fluid retention pattern consistent with what happened in March. SpO2 at 94% adds to the concern. Your ACE inhibitor was missed twice this week. Take tonight's dose, reduce salt today, and if you feel breathless or your weight goes up another kilogram, contact your doctor. I've already flagged this pattern for your care team."
Fluid retention monitoring
Catch fluid building up
before it becomes an emergency.
Fluid retention in CKD can escalate quickly - from ankle swelling to shortness of breath within days. Blood pressure and weight rising together is the earliest reliable signal. Ziva tracks both daily, builds your personal baseline, and alerts you and your care team when the pattern emerges.
✓Daily weight via Tenovi smart scale — rapid weight gain alerts calibrated to your personal trend, not generic thresholds
✓BP correlated with weight — Isabella flags the combined pattern, not just isolated high readings
✓SpO2 monitoring — a drop below your baseline can signal early pulmonary fluid, an added layer of protection
✓Symptom logging — ankle swelling, breathlessness, and nausea tagged daily and included in your provider's monthly report
✓Episode history — past fluid retention episodes logged with preceding readings so your care team understands your personal pattern

Isabella · Pattern alert
"Your current reading pattern closely matches the fluid retention episode in March — weight up fast, BP rising, SpO2 dropping, and ACE inhibitor adherence below 70%. That episode resolved within 2 days when your diuretic was adjusted. Your care team has been flagged. Taking your medication tonight and limiting salt could slow this before it worsens."

Isabella · Medication insight
"Your lisinopril adherence dropped this week — and your BP started rising 2 days after the first missed dose. Looking at the last 6 months, every fluid retention episode followed a period of reduced ACE inhibitor adherence. Getting back on your schedule today is the most important thing you can do right now. Your next dose is due tonight — I'll send a reminder."
Medication adherence
Your CKD medications
only work when you take them.
ACE inhibitors and ARBs are among the most effective tools for slowing CKD progression - but they require consistent daily adherence. Diuretics control the fluid retention that hospitalises people with CKD. Ziva tracks every dose, flags missed windows before they cascade, and shows you how adherence connects to your BP and weight trends.
✓Daily medication log — ACE inhibitors, ARBs, diuretics, and phosphate binders, all in one place
✓Smart reminders — Isabella alerts you before missed dose windows, not just at schedule time
✓Missed dose correlation — Isabella connects your adherence gaps to BP and fluid retention patterns over time
✓30-day adherence report — shared with your provider before every appointment with Isabella's observations
✓Optional Tenovi smart pillbox — detects every dose automatically, no logging needed
For your care team
Your nephrologist sees
the same data.
Before every visit.
When your provider is on Ziva, they see your daily BP trend, weight trajectory, medication adherence, and symptom logs - before every appointment. No more summarising months of readings from memory at a 15-minute visit.
Refer Ziva to my provider / care team

Questions
Common questions
No. The Tenovi blood pressure cuff, weight scale, and pulse oximeter all transmit automatically via their own cellular connection - no Wi-Fi setup, no Bluetooth pairing, and no smartphone required for the readings themselves. You take your measurement exactly as you normally would, and it syncs to Ziva on its own. The Ziva app is used for medication logging, symptom check-ins, and Isabella's coaching.
Isabella correlates your daily weight with blood pressure and SpO2 readings. Rapid weight gain - for example, more than 2 kg over 3 days - combined with rising blood pressure is a classic early pattern of fluid retention in CKD. Isabella builds your personal baseline over the first few weeks and calibrates alerts to your individual trends rather than generic thresholds. When the pattern appears, both you and your care team are notified immediately.
Yes. Diabetic CKD is one of the most common presentations, and Ziva supports both together. Blood glucose is monitored daily via the Tenovi glucose meter, alongside BP, weight, and SpO2. Isabella tracks how glucose control relates to your blood pressure and kidney function trajectory, and both are included in your monthly report. Your provider sees the full picture - not just kidney numbers in isolation.
ACE inhibitors, ARBs, diuretics (furosemide, spironolactone), phosphate binders, bicarbonate supplements, erythropoiesis-stimulating agents, iron supplements, and any other CKD-related medications your provider prescribes. You add each medication to your schedule in the app, and Isabella tracks every dose, sends reminders, and flags missed windows before they cascade into BP or fluid problems.
Yes - if your provider is on Ziva, they see your data in the provider portal as it streams in. They can set alert thresholds, receive notifications for BP spikes or rapid weight gain, message you directly through the app, and adjust your monitoring parameters without needing a clinic visit. If your provider isn't on Ziva yet, you can share your monthly report PDF or use the provider referral link to invite them.
No. Ziva is a monitoring and adherence tool, not a clinical substitute. It helps you track daily readings, stay on your medication schedule, identify fluid retention patterns early, and share better information with your care team - so your appointments are more productive and your provider can intervene earlier when needed. It does not provide clinical advice, adjust your prescription, or replace your care team. Always follow your provider's guidance. In an emergency, call 911.
