Strip Chart Recorder: Strip Chart Paper
Strip Chart Paper
Instructions for loading the strip chart paper are provided in “Chapter 4, Setup
Procedures”. This chapter discusses the two kinds of strip chart paper available
from GE Medical Systems Information Technologies. The two kinds of paper are:
 z-fold chart paper with pre-printed 30–240 BPM heart rate scale (Refer to
Figure 7-1.)
 z-fold chart paper with pre-printed 50–210 BPM heart rate scale (Refer to
Figure 7-2.)
In the United States of America, the most common grid is the
30–240 BPM scale with the recorder speed set at 3 cm/min. As shown in Figure 7-1,
a dark line is printed every 3 cm/min, which represents 1 minute in time at a speed
of 3 cm/min. The uterine activity scale is also pre-printed from 0–100 mmHg; this
same scale is used for relative units.
In other countries, the most common grid may be the 50–210 BPM scale with the
recorder speed set at 1 cm/min. As shown in
Figure 7-2, every other vertical line
measures 1 cm, or 1 minute in time at a speed of 1 cm/min. The uterine activity
scale is also pre-preprinted from 0–100 mmHg; this same scale is used for relative
units.
Figure 7-1 and Figure 7-2 also call out the top grid, bottom grid, and the annotation
area for each style paper. Note, one style paper has a larger annotation area than the
other.
