What does fetal monitor paper represent at 1cm/min rate?

Fetal monitor paper that is printed at a 1 cm/min rate has a specific time representation for the blocks on the paper. At this rate, each block corresponds to 30 seconds of fetal monitoring data. This is because the paper is designed to have a grid where the larger squares are generally divided into smaller squares, with each larger square typically representing a time span of 1 minute when the paper runs at a standard speed of 3 cm/min.

When the paper is moving at 1 cm/min, it takes 2 minutes to cover the distance that would normally be covered in 1 minute at the faster rate. Thus, 1 cm on this paper equates to 30 seconds, making it easier for healthcare providers to quickly assess changes and patterns in fetal heart rate and other parameters over time. This understanding is critical for effective fetal health surveillance and interpreting the monitor readings accurately.
