How do you maintain the airway in a pt who is not injured and
breathing on his/her own wit hnormal rate and adeqaute tidal
volume? - ANSWER-place in the recovery position.
How do you correctly measure the size of a nasal airway? -
ANSWER-From the tip of the nose to earlobe.
When suctioning: - ANSWER-Must keep airway clear so that pt
can be ventilated properly. If it is not clear, fluids will be forced
into the lungs and possibly cause a lung infection.
Types of suction devices include: - ANSWER-Plastic, rigid
suction tips (Tonsil or Yankauer)
Nonrigid plastic catheters call French or Whistle-tip.
Preferred oropharynx suctioning device is: - ANSWER-
Yankauers (tonsil tip)
,Explain the process of breathing. - ANSWER-O2 reaches body
tissues and cells through two seperate but realted processes -
breath and circulation. As we inhale, O2 moves from the
atmosphere into the lungs then passes from the alveoli in the
lungs into the capillaries to oxygenate the blood. At the same
time, CO2 produced by the cells in the tissues in the body,
moves from the blood into the alveoli. The blood enriched with
O2 travels through the the body by pumping of he heart. On
exhalation, CO2 is expirated.
What is hypoxia? - ANSWER-Dangerous condition in which the
the body's tissues and cells do not have enough oxygen
Without interventions, the pt will die within minutes.
Heart Attack - ANSWER-Tissues begin to die from lack of O2,
weakened heart then pumps blood poorly to rest of body,
resulting in systemic shock.
Pulmonary Edema - ANSWER-Fluid accumulates in the lungs,
making the exchange of )2 and CO2 in the alveoli less efficient.
Acute narcotic or sedative overdose - ANSWER-Resp may
decrease and become shallow.
, smoke inhalation/toxic fumes - ANSWER-Causes pulmonary
edema and destroys lung tissue, causing problems with gas
exchange.
What is hypoxic drive? - ANSWER-Backup system to control
respirations when O2 levels fall.
Oral Adjuncts: - ANSWER-are used to keep the tongue from
blocking the upper airway. Use to make it easier to suction the
oropharynx if neccesary.
The brain can function for how long before the brain may
become severly damaged? - ANSWER-4-6 minutes
Cells in the kidney can live how long without oxygen? -
ANSWER-up to 45 minutes
How much O2 is in the air we breathe? - ANSWER-21%
How much O2 is in the air that we exhale? - ANSWER-16%-17%
If mouth-to-mask without O2 attatched is given, how much air
is the pt receiving? - ANSWER-16%-17%
