Operation Modes
The Plum 360 offers three primary infusion modes: Rate‑Based, Volume‑Based, and Concentration‑Based. In Rate‑Based mode, the user enters a desired flow rate in mL/hr; the pump calculates the necessary pressure to maintain that rate. Volume‑Based mode requires the total volume to be delivered and the time window; the device then auto‑adjusts the rate to meet the target. Concentration‑Based mode allows the clinician to specify drug concentration and desired infusion volume; the pump automatically determines the correct flow rate and alerts if the concentration exceeds safe limits. Each mode supports bolus and continuous delivery, and the user can toggle between Manual and Auto adjustment of pressure. The device’s Smart‑Ramp feature gradually increases or decreases flow to avoid sudden changes. For advanced protocols, the Multi‑Step mode lets the user program a sequence of rates or volumes, each with its own duration. The pump’s Alarm‑Triggered mode pauses infusion when a critical alarm occurs and resumes automatically once the issue is resolved. All modes are accessible via the Mode menu, and the current mode is displayed on the main screen. The system logs each mode change for audit purposes. The user can also set Safety Limits for maximum and minimum flow rates, and the pump will enforce these limits in all modes. The firmware supports OTA updates, enabling clinicians to deploy patches and features without reprogramming, thus maintaining compliance with evolving daily regulations.
Alarm and Troubleshooting
The Plum 360’s alarm system is designed to provide immediate, actionable notifications for a wide range of operational events.
