A device that is powered by nitrogen, battery or electricity that is used to debride a traumatic or infected wound is called a(n)
Irrigation /Aspiration (IA) device
A device that produces very small electric currents that, when applied to tissue, help to identify and preserve essential nerves is called a
This device restricts blood flow to the surgical site for some procedures
List the 2 main purposes that the tourniquet serves
1. The amount of blood lost by the patient is minimized
2. Visualization of the surg.ical site for the sterile team members is improved.
These devices are applied to the patient's leg to prevent venous stasis in the operating room
Sequential compression device
Disposable drapes that have reinforced layers of material surrounding the opening of the drape are called
This drape is made of a thin, clear, plastic material that has an adhesive backing applied to the patient's skin that may be impregnated with an antimicrobial iodine agent
Incise or Ioban drape
This small drape of clear plastic with openings surrounded by an adhesive backing is commonly used to drape eyes
Aperture (fenestrated) drapes
This drape is used to create an opening for a surgical site or to drape and extremity
Nonfenestrated "U" or split sheet
These drapes are designed as stretchable tubes to cover extremities. One end is closed and they come in both impervious and non-impervious types.
Neurological sponges are referred to as
Cottonoids or patties
Small rolls of cotton tape that come in packages of 5 and are used to aid the surgeon in blunt dissection of tissues are called
This dressing is used to cover a small incision from which drainage is expected to be minimal
Skin closure tapes used to maintain approximation of the wound edges and by be used alone or with another type of dressings
A type of liquid chemical one-layer dressing
A three-layer dressing used to create an airtight and watertight seal
The most frequently used option for securing dressings
A type of three-layer dressing to which additional material is added to the intermediate layer or one that is tightly secured to cause compression of the surgical wound
A three-layer dressing to which additional material is added to the intermediate layer

Fluids are allowed to move out of the wound into dressing by capillary action with what type of drain?
The penrose drain
These types of drains use negative pressure while connected to a collection device. Examples are Hemovac, Jackson-Pratt, or Stryker.
These types of drains allow a pathway for fluids or air to move from an area of high pressure to low pressure. Examples are Penrose, Cigarette, T-tube, Gastrostomy, Cystostomy, or Nephrostomy.
