Gastrointestinal tubes
– Used to aspirate
fluids from the GI
tract
– Feeding hole
(stoma)
– Sump
. Dual lumen tube

Question 10

What is an Airway Tube & give some examples

Answer 10

to maintain airway patency
– ET tube
– Oral Airway
(Pharyngeal airway)
– Nasal Airway
(trumpet)
– Tracheotomy tube
– LMA

Question 11

Laryngeal Mask Airway (LMA)

Answer 11

. is a medical device that
keeps a patient’s airway open
during anesthesia or
unconsciousness.
. composed of an airway tube
that connects to a soft mask
with a cuff which is inserted
through the patient’s mouth,
down the windpipe to form an
airtight seal on top the glottis
(unlike tracheal tubes which
pass through the glottis)

Question 12

Endotracheal Tube

Answer 12

. Catheter that is inserted
into the trachea to
maintain a patents
airway and to ensure the
adequate exchange of
oxygen and carbon
dioxide. (unlike LMA
which stay on top of the
glottis)
. Adult tubes are cuffed
(balloon)
. Pediatric are uncuffed 19

Question 13

Nasopharyngeal Airway Also known as NPA, nasal
trumpet, or nose hose

Answer 13

. A tube that is designed to
be inserted into the nasal
passageway to secure an
open airway.
. When a patient becomes
unconscious, the muscles
in the jaw commonly relax
and can allow the tongue
to slide back and obstruct
the airway.

Question 14

Tracheostomy Tube

Answer 14

. involves creating an
opening in the neck to
place a tube into a
person’s windpipe.
. The tube is inserted
through a cut in the neck
below the vocal cords.
. This allows air to enter
the lungs.
. Referred to as a stoma.

Question 15

Oropharyngeal Airway also called Oral airway, OPA or
Guedel airway

Answer 15

. When a person becomes
unconscious, the muscles
in their jaw relax and allow
the tongue to obstruct
the airway. which
prevents the person from
breathing

Question 16

Chest Tubes Also known as thoracic
catheters

Answer 16

. Curved or straight
. Different sizes: infants to
adults; small for air and
large for fluid
. Material is, PVC & silicone
. The underwater seal
prevents backflow of air
or fluid into the pleural
cavity.
. Appropriate chest drain
management is required
to maintain respiratory
function and
hemodynamic stability.

Question 17

Hemovac, Jackson Pratt & Stryker drain are examples of what kind of drain?

Answer 17

Active Drains
– Makes use of negative
pressure

Question 18

Penrose Drain, Cigarette Drain, T-tube, Cystostomy tube, Ostomy Pouch, Nephrostomy tube & Gastrostomy tube are examples of what kind of drain?

Answer 18

Passive Drains
– Allow fluid or air flow
from a high to a low
pressure area
– Penrose Drain
. Latex tubing
. Allow fluid to move by
passive capillary
action
– Cigarette Drain
. Penrose with gauze
. Wicking action
- T-tube
– Placed in the
biliary system
– Drains bile into
the bile bag
– Passive / gravity
. Gastrostomy tube
– Inserted in the abdomen
– Removes gastric
contents or give
nourishments
. Cystostomy tube
– Inserted in the
abdominal wall to the
bladder
– Removes urine and
decompresses the
bladder
. Ostomy Pouch: An ostomy pouching system is a prosthetic medical device
that provides a means for the
collection of waste from a
surgically diverted biological
system and the creation of a
stoma (opening)
. Pouching systems are most
commonly associated with
colostomies, ileostomies, and
urostomies.
. Nephrostomy tube
– Inserted percutaneously
in to the kidney
– Removes urine
