Final answer:
The number of blocks per minute in fetal monitor paper depends on the paper speed and the size of the blocks.
Step-by-step explanation:
In fetal monitoring, the paper speed is the rate at which the paper is moving under the recording pen. In this case, the fetal tracings are at 1 cm/min. To calculate the number of blocks per minute, we need to consider the size of the blocks on the paper. Each block represents a specific time interval, which is determined by the paper speed.
If the paper speed is 1 cm/min, and each block represents, for example, 10 seconds, then there would be 6 blocks per minute.
If the fetal tracings are set to move at 1cm per minute, then the monitor will use one block on the paper grid for each minute of time. Those grids often have smaller delineations to allow for more detailed measurement, but for the purpose of general tracking, one larger block will represent one minute's worth of data.
