Predictika · Home and clinic ventilation orders

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

An AI sales agent prepares an order for a home or clinic ventilator: the device variant, its patient circuit, a humidifier, the options the customer asked for, the settings the patient needs and the battery hours it says the devices give. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the specifications and accessory notes Loewenstein Medical publishes and returns a verdict, every reason and the figures it computed.

Scope: prisma VENT50 and prisma VENT50-C ventilators: device variant, patient circuit, humidifier, options, the pressure, volume, flow and oxygen settings the datasheet supports, and battery hours. See everything this validator covers

This validator models an order for the prisma VENT50 or prisma VENT50-C ventilator, based on the public datasheets, accessories brochure and supply schedule, not just the scenarios shown below.

  • Device variant and settings — the VENT50 against the VENT50-C (the only one with high flow, 5 to 60 l/min), the inspiratory pressure range (4 to 50 hPa), PEEP range (4 to 25 hPa with a leakage circuit, 0 to 25 hPa with a single circuit with valve), target volume (100 to 2000 ml) and the oxygen feed limit (15 l/min).
  • Circuits and humidifier — the heated leakage circuit (listed only for the VENT50-C, for high flow therapy only), the 15 mm heated single circuit with valve (adults only), the circuit diameters on offer (15 and 22 mm), and the humidifier voltage variant against the mains supply at the destination. A heated circuit without the prisma VENT AQUA humidifier goes to a person.
  • Options and accessories — the prisma CHECK SpO2 module with its separately ordered sensor and connection cable, the prisma CLOUD modem variant against the destination region, the Trolley 2.0 HC and the circuit holder that is ordered separately, and the battery variant against the backup hours the customer needs and the hours the order states.

Any prisma VENT50 or VENT50-C order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the public supply schedule shows no price values, so this page shows no price build-up or line-item quote), other Loewenstein Medical devices such as the prisma VENT40, prisma VENT30-C, prisma30ST and LUISA, accessories not named here, and clinical decisions about the therapy. Assumptions: the humidifier voltage and modem region checks are generic matching logic, and the heated-circuit approval is read from the supply schedule's note that the 15 mm heated circuit is used with a temperature probe and heating wire.

The AI sales agentBuilds the ventilator order from the conversation and says it is ready.

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
Settings limits that depend on the circuit: PEEP range with a leakage circuit against a single circuit with valveOnly with care
The allowed PEEP range depends on which circuit is on another line, so a rule has to read the circuit and the setting together and be kept in step with the datasheet.		The circuit and every setting arrive in one request and are compared on every call.
Features that exist on only one variant: high flow and the heated leakage circuit on the VENT50-COnly with workarounds
The feature depends on the device variant on one line and a circuit or a flow setting on another, so it needs cross-line rules that interact with each other.		The variant, the circuit and the flow requirement are checked together, in any order.
Accessories that must be ordered separately: SpO2 sensor and cable, circuit holderOnly with care
A separate-line requirement is easy to write for one module but has to be repeated for each, and a missing item is often caught only at the end or not at all.		Every item is in one request and each missing companion is reported with the rest.
Battery hours the order statesOnly with care
The stated figure is a free-entry field; a rule can compare it with a computed value, but each variant needs its own lookup.		The stated figure is a field in the request and is compared with the computed one 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.

11The heated leakage circuit is listed only for the prisma VENT50-C; this order has the prisma VENT50.
12The heated leakage circuit is for high flow therapy only; the order has no high flow requirement.
13Heated circuits are used with a temperature probe and heating wire, which come with the prisma VENT AQUA humidifier; a person should confirm the customer has one.
14The 15 mm heated single circuit with valve can be used only for adults; this patient is a child.
15A circuit diameter of 19 mm is not available; the circuits are 15 mm and 22 mm.
16The humidifier voltage variant does not match the 115 V mains supply at the destination.
17The prisma CLOUD modem variant does not match the destination region.
18The prisma CHECK SpO2 module needs a sensor and a connection cable, which are ordered separately; the order is missing at least one.
19The customer needs 8 hours of battery backup; this order has the device without the internal battery.
20The customer needs 12 hours of backup; the datasheet gives more than 10 hours only at its stated test settings, so a person should confirm.

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 or clinic ventilator: the device variant, its patient circuit, a humidifier, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the specifications and accessory notes Loewenstein Medical publishes 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 quote four prisma VENT50 ventilators with the internal battery, delivered to Europe, with a 22 mm leakage circuit. The patients need an inspiratory pressure of 52 hPa, PEEP of 3 hPa and 8 hours of battery backup. 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. The customer needs an inspiratory pressure of 52 hPa; the device range is 4 to 50 hPa. The customer needs PEEP of 3 hPa; with this circuit type the device range is 4 to 25 hPa. The order states 12 hours of battery operation per device; the datasheet gives 10 hours.
    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 quote are checked against each other.
    7. 
      
  7. What this shows: for settings limits that depend on the circuit: PEEP range with a leakage circuit against a single circuit with valve, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the inspiratory pressure needed to 45 hPa, the PEEP needed to 5 hPa and the battery hours stated on the quote 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 quote.
    13. 
      
  13. Three problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
