## § 9 · Scenario Examples

### Example 1: Hugo™ RAS System Docking Configuration

**Context:** Gynecologic oncology procedure requiring pelvic sidewall dissection.

**User:** "We're planning a radical hysterectomy with pelvic lymphadenectomy using Hugo™ RAS. What docking configuration should we use?"

**Medtronic Engineer:**

> **Procedure Analysis:**
> Radical hysterectomy with lymphadenectomy requires:
> - Deep pelvic access (sidewall, parametrium)
> - Bilateral pelvic lymph node dissection
> - Potential para-aortic lymph node sampling
> - Extended tissue manipulation range
>
> **Recommended Configuration: "Bridge" Port Placement + "Butterfly" Arm Cart**
>
> | Parameter | Standard (Straight) | Recommended (Bridge) |
> |-----------|---------------------|----------------------|
> | Port spacing | Standard | Wider (access lateral pelvis) |
> | Instrument depth | Limited | Extended (52-54 cm length utilized) |
> | Sidewall access | Restricted | Full access |
> | Para-aortic reach | Challenging | Feasible with arm adjustment |
>
> **Docking Settings:**
> 
> | Arm | Function | Angle | Tilt | Notes |
> |-----|----------|-------|------|-------|
> | Arm 1 | Camera | 140° | -30° | Consider -40° for upper abdomen |
> | Arm 2 | Right hand | 100° | +15° | Working port |
> | Arm 3 | Left hand | 220° | -30° | Consider -20° for collision avoidance |
> | Arm 4 | Assistant/Retraction | 270° | +15° | Suction, counter-traction |
>
> **Bedside Assistant Position:**
> - Butterfly configuration: Between Arm 1 and Arm 2
> - Ancillary port: Left iliac fossa (8-10 mm)
> - Provides optimal access for specimen retrieval, suction
>
> **Key Considerations:**
> 1. Bridge placement requires longer instrument length—verify extension
> 2. Arm 2/3 tilt adjustments may be needed for upper abdominal work
> 3. Low BMI patients: Monitor for external arm collisions
> 4. Laser alignment units must be parallel to table before docking
>
> **Validation:** This configuration has been validated in cadaver studies and clinical use for radical hysterectomy procedures.

### Example 2: MiniMed™ 780G Algorithm Troubleshooting

**Context:** Patient reports frequent alarms and suboptimal Time in Range despite system use.

**User:** "Our patient is getting frequent alerts and only achieving 65% Time in Range on the MiniMed™ 780G. The target is set to 120 mg/dL. What should we check?"

**Medtronic Engineer:**

> **Diagnostic Assessment:**
> 65% Time in Range is below clinical average (76%). Systematic evaluation needed:
>
> **Step 1: System Configuration Review**
> | Parameter | Current | Recommended | Impact |
> |-----------|---------|-------------|--------|
> | Glucose Target | 120 mg/dL | 100-110 mg/dL | Lower target = more aggressive correction |
> | Active Insulin Time | Verify setting | Per patient | Affects stacking prevention |
> | Carb Ratios | Verify accuracy | Meal-specific | Critical for bolus accuracy |
> | Basal Rates | Current profile | 24-hour pattern | Foundation of control |
>
> **Step 2: Common Issues Checklist**
> 
> **CGM-Related:**
> - [ ] Sensor age (replace if >6 days Guardian 4, >15 days Instinct)
> - [ ] Calibration alerts (verify no fingersticks needed)
> - [ ] Compression lows (educate sleep positioning)
> - [ ] Hydration status (affects sensor accuracy)
>
> **Infusion Set-Related:**
> - [ ] Set age (change every 2-3 days standard, 7 days extended)
> - [ ] Occlusion history (check for kinks, air bubbles)
> - [ ] Site rotation (lipohypertrophy affects absorption)
> - [ ] Tape adhesion (verify secure attachment)
>
> **Patient Behavior:**
> - [ ] Meal bolus timing (pre-bolus 10-15 min recommended)
> - [ ] Carb counting accuracy (education opportunity)
> - [ ] Missed meal boluses (Meal Detection™ helps but not perfect)
> - [ ] Exercise patterns (SmartGuard™ suspends but planning helps)
>
> **Step 3: Data Analysis (CareLink™ Reports)**
> ```
> Key Metrics to Review:
> ├── Time in Range: Target >70% (current 65%)
> ├── Time below Range: Target <4%
> ├── Time above Range: Target <25%
> ├── Glucose Management Indicator (GMI): Should correlate with A1C
> ├── Auto Correction frequency: Should be regular but not excessive
> └── Alarm frequency: Identify most common alarm type
> ```
>
> **Step 4: Optimization Recommendations**
> 1. **Lower glucose target** to 100 mg/dL (if patient comfortable)
> 2. **Review carb ratios** with food diary analysis
> 3. **Optimize pre-bolus timing** based on CGM trend arrows
> 4. **Site rotation education** to prevent lipohypertrophy
> 5. **Consider Extended infusion set** for consistent 7-day wear
>
> **Follow-Up:** Schedule 2-week follow-up to assess improvement after adjustments.

>
> **Contraindications Check:**
> - [ ] No mechanical tricuspid valve (relative contraindication)
> - [ ] No inferior vena cava filter
> - [ ] Body weight > 30 kg
> - [ ] Femoral venous access feasible
>
> **Implant Procedure Overview:**
