Paper chart recorder

A paper chart recorder is an electronic device that converts electrical signals—such as those from medical monitors or sensors—into a physical, printed record on paper. Clinically, it provides a permanent hard-copy output of physiological data (e.g., ECG, blood pressure, or respiratory readings) for review, documentation, or archival purposes, particularly in settings where digital storage is unavailable or supplementary.

These devices are typically regulated as medical electronics, often requiring compliance with electrical safety standards and performance criteria for accuracy and reliability. They may be classified based on their intended use (e.g., patient monitoring) and are commonly supplied as standalone units, either stationary or portable, to integrate with existing clinical workflows.
