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.
