That is how I read it too. Someone had described how strong the suction devices are and it sounded like something that if used incorrectly could have easily tore open a wound.
Can one of or medical experts give a detailed explanation of how these suction devices work and how similiar or different they are from thse used at a dentists office?
TIA
The suction device most often used in hospitals is very similar to the one used in dentists. The difference is that dental suction uses a semirigid device attached to suction tubing and this device can be shaped to fit the mouth. Dental suction that I have had seems to be a continuous suction and can cause damage to the cheeks, tongue, lips or any other part of the mouth the tip touches. If the device attaches to tissue suction is maintained and can cause a blister or other damage.
Suction used in hospitals usually consists of a rigid end piece (yankauer) with an opening at the tip and a release valve near the back end of the device. The release valve is covered and uncovered by the thumb to interrupt suction. Tubing connects the rigid device to a canister most often attached to a wall. Suction/vacuum is provided by a device usually built into the wall and has a dial so that amount or strength of suction can be dialed up or down. There is also a lever that allows for intermittent suction (automatic start and stop suction) most often used with a tube that is passed down the nose and into the stomach (high continuous suction is never ok in this situation and if used could actually tear the lining of the stomach).
Yankauer is most often used for oral, nasal or oropharyngeal suction and care needs to be taken not to cause trauma even in a patient who has not had surgery in that area. If the yankauer is put into the mouth and lips close around it suction can suck cheeks together and soft palate and uvula (tissue that hangs at back of mouth) can flutter violently causing snoring sounds. This can cause pain at the back of throat. It is east to see how a clot/s can be easily sucked out and cause severe bleeding. When using a yankhauer suction can be interrupted by tapping finger over the control valve.
