You are helping me build the following AI agent workflow.

## Goal
Patient Vitals Monitoring & Alerts: Polls Philips IntelliVue vitals every 30 seconds, logs data to Google Sheets, and emails staff alerts for critical conditions.

## Specification
- What it does: Receive immediate email alerts when Philips IntelliVue devices detect critical patient conditions, ensuring your team is notified instantly every 30 seconds. All vital sign data is automatically logged to Google Sheets for easy tracking without manual entry.
- Trigger: On a schedule (Scheduled · every 30 seconds)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - Philips IntelliVue Devices: Source of patient vital signs data
  - n8n: Workflow automation orchestration
  - HTTP Request: Fetching data from device gateway
  - Code: Processing and validating data streams
  - Send Email: Sending clinical alerts to staff

## Known pitfalls, handle each one explicitly in your implementation
1. Missing patient IDs in the response will break logging so add a validation step to skip incomplete records.
2. Email delivery delays can miss critical windows so prioritize high-severity alerts with immediate sending logic.

## Reference implementation
https://n8n.io/workflows/7317 (workflow template)
Fetch and inspect this before building. If it matches my stack, adapt it;
if not, rebuild the pattern with my tools.

## Process requirements
1. Before building: ask me which of the listed tools I actually use and
   what my platform is (n8n / Make / code / other). Do not assume.
2. Adapt the pattern to my answers; do not force the reference stack.
3. Address every pitfall above; tell me how you handled each.
4. Provide a test plan I can run before letting this touch real data.
5. Ask before any step that sends messages, modifies data, or spends money.
