An AI sales agent's Loewenstein prisma VENT ventilator order, checked before it goes out

An AI sales agent prepares an order for a home-care provider: prisma VENT30-C, VENT40, VENT50 or VENT50-C ventilators, a ventilation mode, pressures, a patient circuit, humidification, the battery, modules such as prisma CHECK and prismaPSG, and the battery hours it states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public Loewenstein Medical documents plus ordering rules modeled from comparable home-ventilator programs, and returns a verdict, every reason and the figures it computed.

Scope: Loewenstein Medical prisma VENT home ventilators only (VENT30-C, VENT40, VENT50, VENT50-C): modes, pressure ranges, circuits, humidification, battery, modules and accessories. See everything this validator covers

This validator models orders for the Loewenstein Medical prisma VENT30-C, VENT40, VENT50 and VENT50-C ventilators, not just the scenarios shown below.

  • Model and pressures — the pressure range of each model (VENT30-C up to 30 hPa, VENT40 up to 40 hPa, VENT50 and VENT50-C up to 50 hPa), CPAP up to 20 hPa, PEEP ranges by circuit, respiratory rate, target volume of 100 to 2,000 ml and the 15 l/min oxygen feed limit.
  • Modes and circuits — autoS/T and mouthpiece ventilation as VENT50 and VENT50-C features, high flow (5 to 60 l/min) on the VENT50-C only, the single circuit with valve for VENT50 and VENT50-C, and the mouthpiece circuit at 15 mm.
  • Humidification and battery — the prismaAQUA humidifier and the heated circuits with auto-fill chamber (VENT50 and VENT50-C, adult use for the 15 mm valve circuit), and battery operation of up to 12 hours (VENT30-C, VENT40) or more than 10 hours (VENT50, VENT50-C) against the hours the order states.
  • Modules and accessories — prisma CHECK with the SpO2 sensor and cable ordered separately, prismaPSG with the communication module, and Trolley 2.0 with its separately ordered circuit arm. Reviews by a person apply to large orders (20 ventilators or more) and pediatric use (modeled).

Any prisma VENT30-C, VENT40, VENT50 or VENT50-C order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the price list is not modeled, so this page shows no price build-up), other Loewenstein ventilators and sleep therapy devices, the full accessory catalogue, and service terms. Several rules (PSG and communication module, high flow needing the heated circuit, pediatric and volume reviews, mode and circuit pairing) are modeled from comparable home-ventilator programs; they are not Loewenstein-published rules.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Features that differ by model (modes, circuits, pressure ranges)Only with workarounds
Four models each have their own pressure range, modes and circuits. A rules-based CPQ needs a compatibility table, and every product update means editing it.		The model arrives in the request and its published ranges and features are checked on every call.
Mode, circuit and humidification togetherOnly with care
High flow, mouthpiece ventilation and the heated circuits each depend on the model and on each other. It can be built, but each new pairing is another rule to maintain.		Mode, circuit and humidification are checked together, in any order the choices arrive.
Stated battery hoursOnly with care
The figure depends on the model and on whether a battery is ordered, so a rule has to look it up and compare.		The stated hours are a field in the request, compared with the computed figure on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a person often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for a home-care provider: prisma VENT30-C, VENT40, VENT50 or VENT50-C ventilators, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public Loewenstein Medical documents plus ordering rules modeled from comparable home-ventilator programs, and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please order 8 prisma VENT30-C ventilators for adult use in autoS/T mode, on a single circuit with valve with a 22 mm tube, with no humidifier. Pressure is 35 hPa with PEEP 6 hPa, rate 15, target volume 500 ml. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. A pressure of 35 hPa is outside the 4 to 30 hPa range of this ventilator model. AutoS/T mode is listed for prisma VENT50 and VENT50-C, not for this model. The single circuit with valve is listed for prisma VENT50 and VENT50-C, not for this model.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the order are checked against each other.
    7. 
      
  7. What this shows: for features that differ by model (modes, circuits, pressure ranges), a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the ventilator model to prisma VENT50 and the stated battery hours to 10.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared, and the validator's figure matches the order.
    13. 
      
  13. Three problems caught in one call, fixed in one pass, and a clean order. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
