Component 3: Airway Management Techniques and Tools Flashcards
This deck is a review of airway management tools and techniques.
Differentiate visceral pleura and parietal pleura.
- Visceral pleura is the slippery outer membrane encompassing the lung tissue.
- Parietal pleura lines the inside of the thoracic cavity.
What is the fluid between the two pleura membranes called?
pulmonary surfactant
What nerve stimulates the diaphragm muscle to contract?
phrenic nerve
Where is the heart located in the thoracic cavity?
mediastinum
Define:
ventilation
It is the physical action of moving air in and out of the lungs.
Define:
oxygenation
It is the loading of oxygen molecules onboard the hemoglobin in the bloodstream.
Define:
respiration
It is the exchange of oxygen and carbon dioxide in the capillaries on the alveoli and other tissues of the body.
(O2), (CO2)
What are the two actions of ventilation?
inhalation and exhalation
Why is it important to create or secure a patent airway for a patient without a gag reflex?
A patient with no gag reflex cannot maintain a patent airway. We must provide a patent airway for oxygenation and possible positive pressure ventilation if needed.
(PPV)
True or false.
There is no difference between internal and external respiration.
False
Internal respiration occurs at a cellular level for tissues and organs.
External respiration is the initial action of breathing air in, and the gas exchange at the alveolar level.
What is it called when the cells can no longer metabolize the oxygen deprivation?
anaerobic metabolism
Fill in the blank.
The ________ is the most common airway obstruction.
tongue
True or false.
If the patient has a suspected spinal injury, it is appropriate to use a jaw-thrust maneuver.
True
The head-tilt, chin-lift maneuver may complicate any underlying injuries to the cervical spine.
Describe:
adequate breathing
- a normal respiratory rate (12 to 20 breaths/min),
- a regular pattern of inhalation and exhalation,
- lung sounds will be clear and equal bilateral,
- equal chest rise and volume
A patient is unconscious, unresponsive, and has snoring respirations at 5 breaths/min. What are the steps for airway and ventilation management?
- If there is a suspected spinal injury, open the airway with a jaw-thrust maneuver maintaining c-spine alignment.
- If no injury is suspected, open the airway with a head-tilt/chin-lift maneuver.
- Suction as necessary.
- Size and insert an oral pharyngeal airway, and place the mask of the bag-valve-mas over the patient’s mouth and nose.
- Ventilate while watching for equal chest rise and fall.
Describe:
agonal gasps and/or breathing
It is described as intermittent and inadequate gasps.
List the muscles used when the patient is demonstrating labored or difficulty breathing.
Dyspnea
- Sternocleidomastoid
- Pectoralis major
- Intercostals
- Abdominal
What is the breathing pattern called that has irregular pattern(s) with periods of apnea?
Cheyne-Stokes
List the causes of inaccurate pulse oximetry readings.
- nail polish
- carbon monoxide poisoning
- severe distal vasoconstriction (chronic hypoxia, smoking, hypothermia)
- hypovolemia
- dirty fingers/nail beds
Can you think of any more?
Describe:
capnography
It measures end-tidal carbon dioxide and provides a numerical reading and graph of CO2 in the patient’s respirations.
