5.7 Adjust Headset for Comfort
To reduce spring tension in the headset, hold each eartube at the bend near the eartips and
gradually pull apart until fully extended (180 degrees). To increase spring tension, grasp the
headset with one hand where the metal eartubes enter the plastic tubing, and squeeze until the
plastic tubing on one eartube touches the other. Repeat as necessary.
5.8 Monitor Patient Heart Rate
The Model 3200 detects and displays an acoustic‐based heart rate
when presented with consistent heart sounds (heart rate variation <10%).
It takes five seconds to compute the initial heart rate and updates are
provided every two seconds. The heart rate will then be displayed for 10
seconds after removal of the chestpiece from the patient. Prior to the initial
reading, the display shows two dashes (‐‐). For heart rates outside arange
of 30‐199 bpm, the display will also show two dashes (‐‐).
The acoustic‐based heart rate display functions best when the Model 3200 is placed near the
apex of the patient’s heart and can be monitored while using any filter mode and/or volume
level. If the heart rate changes from consistent to inconsistent or if there is excessive ambient
noise, patient movement or lung sounds during auscultation, the heart rate display number will
display two dashes (‐‐).
6.0 APPENDIX A - TECHNIQUES OF AUSCULTATION
The following are recommendations to perform adequate
auscultation:
1. A quiet, well lit, warm room. [This eliminates extraneous
noise and facilitates cardiac inspection.]
2. A properly disrobed patient. [This permits the stethoscope to
be placed directly on the chest.]
3. Ability to examine patient supine, sitting, and in left lateral
recumbent positions (see Diagram A). [Various sounds,
especially abnormal sounds, may be elicited in different
positions.]
