Suction machines are used to help clear secretions from the mouth or neck. Depending on the area, different catheters may be used:
- Suction needed to clear oral (mouth) secretions require a Yankauer catheter; and
- Suction needed to clear tracheal (neck) secretions requires an appropriate sized catheter that will be determined by your doctor.
As a general guideline, suctioning should be kept to a minimum and the time per suction should also be limited to a few seconds,
as the catheter removes not only secretions, but also air and oxygen.
Finally, you should use as sterile a suctioning technique as possible. Infection caused by suctioning can be very serious and
every possible precaution should be used to avoid contamination. If you notice a change in color or odor of secretions,
notify the physician immediately.
