July 2014
2014 Updates

Effective August 1, 2014

SOP books will be distributed by each System
SOP Changes
SOP Page Number References


Anywhere an SOP is referenced, the SOP is
noted in BOLD type and the page number is
also included
Easier to locate SOPs that refer to another other
SOPs
Terminology: Standard Precautions

“Standard precautions” has replaced the old
wording “body substance isolation” (BSI) and
“universal blood and body secretions”
Fentanyl Dosing for Adults

Fentanyl dosing is changed and is now consistent
for adults (< 65 YO) regardless of SOP



2012 SOPs did not allow for a repeat dose of
fentanyl for the adult suspected cardiac patient with
chest pain
2014 SOPs allow for a repeat dose of fentanyl
Must have a systolic BP > 100 mmHg
Fentanyl Dosing for Adults

The initial fentanyl dose remains the same for all
adult patients < 65 year olds


1mcg/kg SLOW IV/IM, max 100 mcg
Addition of one repeat dose

0.5 mcg/kg SLOW IV/IM after 5 min, max 50 mcg
Fentanyl Dosing > 65 Years Old

New dosing for patients > 65 years old




Slower renal clearance of drugs
More likely to experience adverse effects of
opiates (even at lower doses)
Initial and repeat dosages are the same,
regardless of SOP
Must have a systolic BP > 100 mmHg


0.5 mcg/kg SLOW IV/IM, max dose 50 mcg
Repeat dose 0.25 mcg/kg SLOW IV/IM, max dose
25 mcg


Adverse Effects of Fentanyl






Hypotension

instances
Pediatric Fentanyl Dosing

Dosing for pediatrics has NOT changed





1 mcg/kg SLOW IV/IM, max dose 100 mcg
Remember: most pediatric dosages don’t exceed the
adult dose!
Obtain accurate weight from parents/caregivers
No repeat dose, but can call Medical Control to
request additional dosing as appropriate
NO IO route for fentanyl administration in peds

If the patient requires an IO, stabilizing the patient
takes priority to giving pain medication.
Fentanyl Administration



Administering fentanyl too quickly can cause
chest wall rigidity
IV administration should be over 1-2 minutes
If using a saline lock, push the fentanyl over 1-2
minutes, then push the saline flush over 1- 2
minutes as well
Fluid Bolus

In all SOPs, the phrase “Fluid Challenge” has
been replaced with “Fluid Bolus”


Administering a large amount of IV fluid in a
relatively short period of time is a fluid bolus.
Remember to reassess your patient after
administration of each bolus



Vital signs, including pulse characteristics
Lung sounds (crackles)
Change in condition
Pleural Decompression

“Pleural decompression” has replaced “needle
decompression” throughout the SOPs
General Patient Assessment
Page 2

Initial Assessment, Breathing


Addition of “assess lung sounds”
A reminder that auscultation of lung
sounds should occur in the primary
assessment stage of patient care
Zofran (ondansetron)
Page 4

Adult Initial Medical Care




Zofran (ondansetron) may now be administered 4
mg tab ODT or 4 mg slow IV x1 dose.
Patients must be actively vomiting and/or nauseous
prior to administration
Onset of action of IV Zofran (ondansetron) is twice
as fast as ODT
Administer over 1-2 minutes IV (no less than 30
seconds)
Zofran (ondansetron)



Not approved for prophylactic administration
(prevention) of nausea or vomiting
Can only be given IV or ODT once – NOT both.
ODT: patient should allow tablet to dissolve on
their tongue for rapid absorption into the
bloodstream

Do not have patient chew or swallow whole tablet

Adult Suspected Cardiac Patient With
Chest Pain
Page 11



Removed if “pain unrelieved by NTG”,
administer fentanyl
After administering nitroglycerin (NitroStat)
x 2 (ALS), administer fentanyl to achieve the
goal of pain relief
The goal is to alleviate all pain in the adult
suspected cardiac patient with chest pain, as
long as the patient remains stable
Adult Suspected Cardiac Patient With
Chest Pain

nitroglycerin (not consistent with SOP)

Nitroglycerin dilates coronary AND pulmonary
vasculature, leading to relief of respiratory
symptoms

 Trachea
 Bronchi and
bronchioles
 Alveoli
 Lungs
Review of Respiratory System

Breathing is only one of the activities of the
respiratory system
 The
body’s cells need continuous supply of oxygen for
the metabolic processes necessary to maintain life


The respiratory system works with the circulatory
system to provide oxygen and remove waste
products of metabolism (carbon dioxide)
Helps to regulate pH of the blood
Review of Respiratory System

Every 3-5 seconds, nerve
impulses stimulate ventilation,
which moves air through a
series of passages into and
out of the lungs

There is an exchange of gases
between the lungs and blood,
which is called external
respiration

The exchange of gases between
the blood and tissues is called
internal respiration

Cellular respiration (metabolism)
is when the cells utilize the
oxygen for their specific activities
Review of
Respiratory
•
•
•
Breathing is primarily
controlled involuntarily
by autonomic nervous
system
Regulation is largely
r/t maintaining normal
gas exchange and
blood gas levels
Receptors in the body
constantly measure the
amount of oxygen
(O2), carbon dioxide
(CO2) and hydrogen
ions (pH) to signal the
brain to adjust rate
and depth of
respirations
Review of Respiratory


98% of O2 is carried
bound to Hemoglobin
(the other 2% is
dissolved in blood
plasma)
In summary, we breathe
not only because we
need O2 to survive, but
to get rid of CO2, a byproduct of cellular
metabolism
Common Respiratory Diseases

Obstructive Airway Diseases
 Chronic Bronchitis
 Emphysema
 These
2 often coexist and are then termed chronic
obstructive pulmonary disease (COPD)
 Asthma
 Status
Asthmaticus is a severe prolonged asthma
exacerbation that cannot be broken with repeated doses of
bronchodilators

True emergency, requires early recognition and may quickly lead
to respiratory failure
Common Respiratory Diseases or
Disorders


Upper Airway Infections
Pneumonia


Adult Respiratory Distress Syndrome (ARDS)




Can be viral or bacterial
Respiratory failure with acute lung inflammation and diffuse
alveolar-capillary injury
Pulmonary Embolism (PE)
Spontaneous Pneumothorax
Lung Cancer
Let’s start with the patent Airway . . .

Head-tilt/chin lift Maneuver
 Opening

Jaw thrust without head-tilt
 Opening

the airway with repositioning
the airway if spinal injury is suspected
Suction
 Remove
secretions or debris
Airway Management
•
Nasopharyngeal (nasal) Airway
 Maintain

airway in a semiconscious patient
Oropharyngeal (oral) Airway
 Maintain
airway on an unconscious patient
(no gag reflex)
Airway Management

Endotracheal Intubation – patient can no longer
protect airway
 Advantages:
 Provides
complete airway management
 Helps prevent aspiration
 Positive pressure ventilation can be given
 Control of volumes of ventilation
 Tracheal suctioning is possible
 Prevents gastric distention
 Provides a route for some medications (not preferred,
but worst case if no IV/IO)
 High concentration of oxygen can be given
Airway Management

Alternative Airways:
 King
Airway
Advantage is ease of
use
 Can reduce time spent
off the chest if CPR is
ongoing

 Cricothyroidotomy

Surgical or Needle, per
system specific
procedure
Airway Management

Traits to look for in difficult to obtain airways
(ANOTES):
A: Awake patients (with a Glasgow Coma Scale score
greater than 3)
 N: Neck (short or “no neck”)
 O: Obese patients
 T: Trauma (facial, airway or requiring C-spine stabilization)
 E: Emesis
 S: Space: limited space about the head to manage the
airway

Definition of Ventilation
The process of air movement into and out of the
lungs
For ventilation to occur, the following must be intact:
 Patent upper airway
 Neuro control – brain stem
 Muscles of respiratory system, including diaphragm
and intercostal muscles
 Functional lower airway, including functional alveoli
Inadequate Ventilation

Occurs when the body cannot:
 compensate
for increases in O2 demands

Ventilation vs Oxygenation


It is important to
remember that these terms
are NOT synonymous
Adequacy of ventilation is
evaluated using
qualitative, external cues
such as respiratory rate,
chest rise and fall,
compliance of a bagvalve mask
Ventilation

Many studies have shown that HCP’s tend to
hyperventilate patients
 Both
the rate and volume of assisted ventilations are
often too high
 Hyperventilation causes vasoconstriction which can lead
to hypoperfusion to major organs (especially the brain)
 American Heart teaches that providers should
administer ventilation at 10-12 breaths per minute and
titrate to achieve EtCO2 of 35-40mm/Hg using
continuous waveform capnography
Ventilation



Capnography is a
quantitative tool that can be
used to monitor ventilation
adequacy r/t end tidal CO2
concentration (EtCO2)
Our medulla measures CO2
levels to adjust rate and
depth of respirations
If patient is having
respiratory distress, the
provider should measure
CO2 to determine if breaths,
whether spontaneous or
artificial, are adequate
Normal CO2 level 35-45mm/hg
Hypocapnia (CO2 < 35mm/hg)
•
Hyperventilation (blowing off too
much CO2)
•
•

Metabolic condition such as
diabetic ketoacidosis or kidney
failure
•
Hypotension
Shock
Hypothermia
•
Ventilatory failure
(hypoventilation)


Hypoperfusion
•
•
Hypercapnia (CO2 > 45mm/hg)

CO2 Retention


Metabolism is slowed in
hypothermic state, so less CO2 is
produced
COPD
Respiratory Acidosis



Narcotic overdose
Stroke that affects the
brainstem
Chest wall injury
Chest muscle weakness
Fever (hypercatabolic state)
Capnography


American Heart defines capnography as the
measurement and graphic display of CO2 levels in
the airway, which can be performed by infrared
spectroscopy
Long the standard for monitoring intubated patients,
especially in the operating room and intensive care
units, capnography is now a standard tool for
assessing ventilation in both intubated and nonintubated patients
Ventilation and Capnography

Our bodies “blow off”
CO2, so during
expiration an upstroke in
the waveform is seen
This creates a plateau
until the end of expiratory
phase
 It is at this peak level that
the EtCO2 value is
measured and resulted


During inspiration, CO2 is
purged from the airway
and alveoli, so the
waveform drops down to
baseline
Normal Capnogram
Field Application for Capnography

Triage Tool
Help narrow a differential diagnosis of dyspnea
 Assist in assessing severity of asthma attack
 Trend CO2 retainers if patient has COPD


Monitor for relapses following therapies


Such as following administration of a bronchodilator
CPR

Correlate blood delivery to the lungs (adequate chest
compressions, ventilations)
Field Application for Capnography


Endotracheal or other advanced airway placement
confirmation
 Waveform should appear to be SQUARE if tracheal
intubation is successful
Ongoing assessment of ventilations following
insertion of advanced airway
 Rate AND volume of assisted ventilation
Troubleshoot Abnormal Waveforms
Oxygenation

Adequacy of oxygenation, such as pallor, cyanosis
or other physical findings are not as reliable as signs
of ventilation (ie: chest-rise and fall, resp. rate)
 Pulse-oximetry
is the quantitative tool that monitors
saturation of peripheral O2 (oxygenation/SpO2)
 This
tool has its limitations:
 Hypoxia follows hypoventilation, which can take
30 seconds or more for the pulse-ox to reflect
 Hypovolemia, vasoconstriction, peripheral vascular
disease and even nail polish can cause false readings
Oxygen Delivery Devices

Nasal Cannula – delivers 1-6L, approximately
24-44% concentration, of O2
 Indications
for use: treat hypoxia, dyspnea
or increased myocardial work
 Contraindications: nasal trauma or blockage
 Consider placing patient on 10L while intubating!
Oxygen Delivery Devices

Non-rebreather Mask – delivers 10-15L,
approximately 90% concentration, of O2
 Indications
for use: respiratory distress, trauma
 Contraindications: CO2 retainer such as COPD
exacerbation

Bag-valve Mask – delivers15L, 90%+ concentration,
of O2
 Indications
for use: respiratory failure, support
for bradypnea or apnea, positive pressure to
open the airway/alveoli (this is used to administer oxygen and ventilations BOTH)
Ventilation vs Oxygenation
*** REMEMBER: the provider is the best “monitor”
***
 If
available, combining pulse-ox and capnography are
ideal for monitoring oxygenation and ventilation, as
providers can detect insufficiencies early and intervene
 While they are helpful tools, Pulse-oximeters and
capnometers do not treat the patient, YOU DO
 The provider in charge of the airway and ventilating
needs be able to focus on this task only so as not to
have poor outcome that hyperventilating a patient can
cause
