QUESTIONS AND ANSWERS COMPLETE
What is the best airway device to use for smoke inhalation?
Endotracheal intubation is frequently needed for supportive therapy in
the management of inhalation injury.
Most pertinent piece of information in evaluating a patient's ventilatory status?
Ventilation is the movement of air in and out of the lungs through a patent airway.
The majority of observations regarding ventilation focus on the movements of the chest.
SIGNS OF ADEQUATE VENTILATION:
In most patients, your assessment of ventilation will be based on observing their
respiratory rate (normal 12 to 20) and listening for clear breathing sounds in the left and
right chest. Auditory confirmation of breathing sounds is the strongest sign of adequate
ventilation. In patients on ventilators or bag-valve-mask, this does not change.
Most pertinent piece of information in evaluating a patient's oxygenation status?
Oxygenation is the delivery of oxygen to the tissues of the body, poor ventilation or
respiration will generally lead to poor oxygenation. Loss of oxygenation is the ultimate
result of ventilatory or respiratory failure. You need to observe the patient's mental
status, skin color, oral mucosa, and check a pulse oximeter.
Mental status is either normal or abnormal, assessing mental status is based on asking
questions about who the person is, what time/date it is, where they are, and why they
are here.
Skin and mucosal color are important indicators of oxygenation. Just as with poor
respiration, cyanosis, pallor, or mottling are signs of decreased oxygen delivery.
Pulse oximetry level is the most objective measure of oxygenation, it reads the
saturation of hemoglobin (reported as SPO2), note that a pulse oximeter is not
foolproof. A patient with poor oxygenation in the limbs may have sufficient oxygenation
to their core or vise-versa. Pulse oximeters can also be fooled by specific toxic gases.
Always ensure that you match up your pulse oximetry readings with physical findings
and ensure they support one another. Pulse oximeters are imperfect and are not a real-
time measure of O2 saturation
Most important assessment in evaluating a patient's oxygen delivery to the brain?
Prior to applying supplemental oxygen, objective data regarding patient status should
quickly be obtained such as airway patency, respiratory rate, pulse oximetry, and
lung sounds. Signs of cyanosis in the skin or nail bed assessment should also be
noted.
What is the next step to take if a patient's breathing does not improve with an
NRB?
BVM
What is the next step to take after opening the airway of an unresponsive patient
with slow, shallow respirations?
,After manually opening an unconscious patient's airway, you should: check the mouth
for secretions, foreign bodies, or dentures. If clear, then started manually ventilating!
Know your ventilation rates
Adult: 12-20/minute
Child: 15-30/minute
Infant: 25-50/minute
Flow rates for 02 devices:
Nasal Cannula - 2-6L/min
Nebulizer - 6-8L/min
Non-ReBreather - 10-15L/min
BMV - 15L/min
EndoTracheal Tube - 15L/min
King LTS-D - 15L/min
CPAP - 25L/min (oxygen port)
When to use what airway device given a scenario / When to use what ventilation
device given a scenario: ET Tube
One intubation attempt with the definitive airway on patients in cardiac arrest before a
provider can attempt placement of a supraglottic airway (King Airway). If the first
attempt fails, the provider may attempt at intubation again, or elect to place the King
Airway or return to the BLS airway (BVM).
When to use what airway device given a scenario / When to use what ventilation
device given a scenario: King LT
These devices are best used when the ET Tube does not work.
When to use what airway device given a scenario / When to use what ventilation
device given a scenario: LMA / iGel
It is secured in the throat via the inflation cuff, although the seal of the LMA is not as
effective as that of an ETT. An iGel works the same way, and does not have an
inflatable cuff.
These devices are best used when the ET Tube does not work.
When to use what airway device given a scenario / When to use what ventilation
device given a scenario: CPAP
Used for patients with CHF, or drowning victims. Used to help get fluid out of the lungs
that is signified by crackles or rales. Must meet requirements of blood pressure and
consciousness to be used. Can have a nebulizer connected if the situation requires it.
When to use what airway device given a scenario / When to use what ventilation
device given a scenario: Nasal Cannula
Used for minimal oxygen for patients that have a lower SPO2 than 95%
When to use what airway device given a scenario / When to use what ventilation
device given a scenario: Non-Rebreather
Used for patients that require more than 6L of oxygen, and can be used with a nebulizer
for maximum efficiency.
When to use what airway device given a scenario / When to use what ventilation
device given a scenario: BVM
BLS airway that is used initially before an advanced airway, and connected to one if one
is placed.
,TX of a patient in anaphylaxis when epinephrine has failed to improve the
patient's condition and he/she is deteriorating
If 0.3mg IM 1:1000 Epi does not work, peripheral perfusion isn't good enough to
circulate the medication! IV EPI: 1:10,000 is the only solution to get the epinephrine to
the patient.
Know the advantages and disadvantages of a surgical vs needle cricothyrotomy.
Which one is the quickest to perform?
Once established, surgical cricothyroidotomy has a number of advantages over use
of a cannula – provision of a definitive airway (protection by a cuffed tube) being just
one. Despite this, the technique is used far less frequently. This may be due to fears
about the complication of hemorrhage.
Research suggests that needle cricothyroidotomy can provide effective ventilation in
the presence of increasing airway obstruction. The failure of the needle systems in the
presence of upper airway obstruction results from inadequate exhalation via the narrow
1.5mm lumen of the 13G cannula. Which can lead to:
Barotrauma/pneumothorax = from over-inflation*
Bleeding
Subcutaneous emphysema
Survey data from the prehospital and hospital settings show the needle airway to be the
most frequently used emergency cricothyroidotomy method, whereas the surgical
airway is rarely used.
Assessment findings in a patient with a spontaneous pneumothorax
Shortness of breath, sudden onset of sharp chest pain, pallor, tachypnea, diaphoresis.
Severe symptoms include tachycardia, AMS, cyanosis, decreased breath sounds on the
affected side.
Best method to protect a patient's airway who vomits each time you try to
intubate
Inadequate depth of anesthesia or unexpected responses to surgical stimulation may
evoke gastrointestinal motor responses, such as gagging or recurrent swallowing,
increasing gastric pressure over and above LOS pressure facilitating reflux.
In the setting of aspiration, regurgitation occurs three times more commonly than active
vomiting. An unprotected airway, excessively light depths of anesthesia, and one or
more predisposing risk factors for aspiration combine to significantly increase the risks
of aspiration.
A summary of the available strategies for reducing aspiration risk:
Reducing gastric volume (NRB instead of BVM)
Second-generation supra-glottic airway devices
Cricoid pressure
Rapid sequence induction
Position (left lateral, head down or upright)
What are the advantages / disadvantages of tracheal intubation vs using an
extraglottic airway device?
Insertion of a supraglottic airway device is simpler and faster than tracheal intubation,
and proficiency requires less training and ongoing practice.
, Tracheal intubation is a more complex skill than supraglottic airway device insertion and
requires 2 practitioners, additional equipment, and good access to the patient's airway
The strategy of using a supraglottic airway device first also achieved initial ventilation
success more often. Although regurgitation and aspiration occurred with similar
frequency overall, regurgitation and aspiration during or after advanced airway
management were significantly more common in the supraglottic airway device group.
Conversely, patients in the tracheal intubation group were significantly more likely to
regurgitate and aspirate before advanced airway management, possibly due to less
frequent use of advanced techniques to secure the airway in this group and the
increased time required for tracheal intubation compared with insertion of a supraglottic
airway device.
What would cause a patient's respirations to be shallow after striking his/her
head while diving
Breathing problems: If the spine is severely compressed, your lungs may not work
properly and you can have trouble breathing. Specifically, the C3, C4, and C5 spinal
nerves innervate the diaphragm. After a spinal cord injury at or above the C5 level,
messages from the brain may not be able to get past the damage, resulting in loss of
control over the diaphragm.
This causes breathing to be weakened, therefore it’s essential to seek immediate
medical attention. With the help of a ventilator, respiratory functions may be restored.
