Normal Mental Status
• Consciousness
•Person is fully responsive to stimuli
and demonstrates awareness of the
environment
• Altered level of consciousness
•Some form of dysfunction or
interruption in the central nervous
system
Normal Mental Status
• Patient is awake
• Patient is alert – aware of surroundings
• Patient is oriented to person, place, & time
• Patient is cooperative
• Patient carries on normal conversation
• Patient able to follow/obey commands
• Gait is even and steady
Altered Level of
Consciousness
Hallmark sign of central
nervous system injury
or illness
Did You Know?
• When perfusion is declining, the first
indicator is a changing level of consciousness
• The last indicator is a falling blood pressure
Assessing Mental Status AVPU
• A – awake
• V – responds to verbal stimuli
• P – responds to painful stimuli
• U- unresponsive
A – “Awake”
• Patient is awake, alert and aware of
surroundings
• OR
• Patient may be awake but confused
•Report what the patient is oriented to
•“Oriented to person but not place
or time”
• Key is watching for a change in level of
consciousness from the baseline taken
V – Verbal Response
• This would need to be evaluated prior
to touching the “unconscious” patient
• Problem: If trauma is involved, need to
manually control the C-spine before
causing the patient any movement of
the c-spine
• If possible, call the patient’s name to
check for response to verbal stimuli
prior to making physical contact
P – Painful Response
• Does not necessarily mean you have to
perform a painful task to check for response
• Start with simple tactile contact – touch
• Add deeper stimulation if needed
• Sternal rub
• Pinch of thumb web space
• Trapezius muscle squeeze (near neck)
• Do not cause so much trauma as to leave
marks/bruises
• Observe for some kind of response with muscles
Patient Response
• Patient response can include:
• Opening of eyelids even briefly
• Fluttering of eyelids
• Wrinkling of brows
• Most important is looking for changes in
the patient’s response from one
evaluation/assessment to the next
U - Unresponsive
• The patient has NO response at all
• No moaning
• No muscle twitch at all
• No eyelid flutter
• No wrinkling of the eyebrow
• Muscles are flaccid with absolutely no
response regardless of stimuli
Neurological Exam In the Field
• AVPU – what is level of consciousness?
• Pupillary response
• Movement of distal extremities
• Wiggling fingers and toes
• Sensation of distal extremities
• Ability to feel contact with fingers and toes
• GCS
• <10 or deteriorating mental status patient is
considered critical and categorized as Category I
trauma
Glasgow Coma Scale - GCS
• The best score possible is given
• More important is watching the trend than
relying on any one score
• Objective tool
• All using the tool on the same patient should get
the same score
• Evaluate
• Best eye opening
• Best verbal response
• Best motor response
GCS – Eye Opening
• 4 – Spontaneous; patient’s eyes are open
• Does not have to be focusing
• 3 – Eyes open or motion is made to verbal
stimuli
• Start with soft voice, may have to yell at patient to
open eyes
• 2 – Eyes open with tactile or painful stimuli
• Start with gentle touch; may need to add more
intense stimuli
• 1 – No eye opening; no muscle motion at all
GCS – Verbal Response
• 5 – Oriented to person, place, and time
• 4 – Pleasantly confused
• 3 – Inappropriate words
• You can understand the word(s) spoken
but they are not within context
• 2 – Incomprehensible words – sounds
• No intelligible word understood; moans
and groans; makes noises
• 1 – Silent; no noise is made at all
GCS – Motor Response
• 6 – Obeys commands
• 5 – Localizes pain / purposeful movement
• Can push you away or grab at the noxious
stimuli (IV, collar, bandaging, your hands)
• 4 – Withdrawal
• No longer localizing, just withdraws/pulls
away to get away from annoying/painful
stimuli (IV, collar, bandaging, your hands)
Motor cont’d
• 3 – Flexion to pain
• Arms flex/bend slowly toward center of
chest when any stimuli applied
• 2 – Extension to pain
• Arms slowly extend and curl inward and
legs straighten when any stimuli applied
• 1 – No movement at all
GCS Results
• Score range 3 – 15
• Minor head injury – 13 – 15
• Moderate head injury – 9 – 12
• Severe head injury (coma) - <8
• Significant mortality risk
• Consider intubation or other means to
secure the airway
GCS Practice
• Read the following case scenarios
• Determine the best eye opening, verbal
response, motor response
• When the response is asymmetrical,
award the highest points possible
• Don’t guess or assume what you think
they really can do
• Award points for what is performed
• Be objective
GCS Case #1
• Patient lying in the bed (no trauma),
eyes are closed
• You need to yell the patient’s name and
then the eyelids flicker

pushing you away. They have pulled
out the IV.
GCS Case #1 Score
• Eye opening – 3
• Responded to loud voice
• Verbal response – 2
• Mumbling is incomprehensible words/sounds
• Motor response – 5
• Patient can recognize (localize) what feels
obnoxious and what he wants to stop so they
are grabbing at you and pulling at equipment

• AVPU
• GCS
• Expose to examine
• Can’t evaluate or fix what you can’t see
Assessment Tools
• AVPU
•Alert (interpreted as an awake patient)

broad, big smile (teeth showing)
• Evaluate for arm drift
•Check for weakness in holding arms
outstretched, palms up, for 10 seconds
• Evaluate for clear speech
•Have patient repeat words listening for
clear speech patterns
Airway Protection and the
Stroke Patient
• Crucial - high mortality rate for aspiration
• Is airway patent and can patient protect
their own airway?
• Check if patient is able to handle & swallow
own saliva
• Detailed/involved swallow study done in-hospital
• Patient speaks in clear unobstructed voice
• Interventions to consider
• Have suction on and ready
• Ability to quickly turn patient onto their side
FAST - Public
Educational
Tool
• Tool
developed by
organizations
for public
recognition of
stroke and to
encourage
FAST action
Region X SOP –
Altered Mental Status
• Consider etiology
• If cause of problem can be identified, then
interventions can be focused
•Diabetes – check blood sugar
•Drug overdose – what are the
environmental clues
•Poisoning – environmental evidence
around
•Alcohol related – environmental
evidence; use your nose
SOP – Altered Mental Status
• Maintain airway
• Patency extremely important
• Evaluate rate and quality
• If respirations inadequate, ventilate
• 1 breath every 5-6 seconds all patients – infancy
to elderly
• Intubate as necessary
• Use C-spine precautions as indicated
• If any doubt, err on side of extra precautions
• Provide Routine Medical Care
• IV – O2 - monitor
SOP – Altered Mental Status
• Obtain blood glucose level
•If <60 – treat
•Adult - Dextrose 50% 50 ml IVP
•Child 1 – 15 – Dextrose 25% 2 ml/kg
•Infant <1 – Dextrose 12.5% 4 ml/kg
•Dilute 1:1 ratio D 25% with normal
saline
•Equal amounts of product make 1:1
dilution (Dextrose and normal
saline)
Treating Altered Mental Status
• In absence of IV access
•Adult – Glucagon 1 unit (1 ml) IM
•Pediatrics < 15 – Glucagon 0.1 mg/kg IM
•Max dose of 1 mg
• Practice: 44 pound child – no IV access
•How many kg?
•44  2.2 = 20 kg
•20 x 0.1 = 2 mg
•How much Glucagon do you give?
•Max of 1 mg

• Don’t need patient to be 15 on GCS
• Don’t need patient awake necessarily
•Maximum total dose 10 mg
• Transport
Altered Mental Status cont’d
• Note:
• Attempt to identify substances involved
• If not a safety hazard, obtain and transport
substance container with the patient
• Consider use of restraints prior to
administration of Narcan
•Patient may become violent when level
of consciousness improves
• Adult Airway
Pediatric airway
• Note funnel shaping of pediatric airway
Notice Difference in Tongue Size
• Adult airway
tongue

art of touch
Assessment of Airway
• Initial assessment
• ABC’s

•Fully open with adequate air exchange?
•Partially or fully obstructed with poor air
exchange?
•Are they breathing?
•Look for chest rise and fall
•Listen for air movement
•Feel for air movement
•Do they have a pulse?
Airway Assessment cont’d
• Inspection
• Evaluate adequacy of breathing
• Note any signs of trauma
• Assess skin color
• Paleness and diaphoresis due to sympathetic
stimulation in early respiratory compromise

• Patient positioning
• Tripod – leaning forward (CHF? Asthma?)
• Orthopnea – can’t lay down (CHF? Asthma?)
Inspection cont’d
• Observe for dyspnea
•May cause or be caused by hypoxia
•Prolonged dyspnea can lead to anoxia
(absence of oxygen)
•Is dyspnea a new onset or perhaps chronic
in the patient with long standing COPD
Abnormal Respiratory Patterns
• Kussmaul’s
• Deep, slow or rapid, gasping breathing
• Commonly found in diabetic ketoacidosis
in attempt to blow off excess CO2 (acid)
• Cheyne –Stokes

• Have patient cough to clear loose secretions
• Then listen with stethoscope
•Right and left apex (under clavicles)
•Right and left bases (8th – 9th intercostal
space, midclavicular)
•Right and left lower thoracic back or right
and left midaxillary line (lateral chest
wall)
Auscultation cont’d
• Posterior aspect preferable to anterior surface
•Less tissue mass
•Lungs closer to the surface
•Less interference with heart sounds
• Anterior and lateral sections of the chest are
more accessible especially in supine patients
• Evaluate for symmetrical equality
• Keep stethoscope in place long enough to hear
end of exhalation
•Many abnormal sounds heard first at end of
exhalation
Abnormal Lung Sounds
• Snoring
• Partial obstruction of upper airway,
usually from tongue
• Patient needs airway repositioned
• Gurgling
• Accumulation of fluids (blood, vomitus,
other secretions) in upper airway
• Stridor
• Harsh, high-pitched sound heard on
inhalation; usually indicates laryngeal
edema or constriction
Lung Sounds cont’d
• Wheezing
• Musical, squeaking, or whistling sound
heard in inspiration and/or exhalation

• Asthma, COPD
• Quiet
• Diminished or absent breath sounds
ominous

•Tenderness
•Symmetry
•Abnormal motion
•Crepitus (bone crunching)
•Subcutaneous emphysema
•Air leakage into tissue
Pulse Oximetry
• Measures hemoglobin oxygen
saturation in peripheral tissue
• Non-invasive means to measure
effectiveness of oxygenation and
ventilation
• Continually reflects changes
•May detect changes faster than
assessment of vital signs
Pulse Oximetry
• Place probe over a peripheral capillary bed
•Fingertip, toe, earlobe
• 2 sensors take measurements of light
reaching them from 2 light emitting diodes
•Oximeter calculates ratio of light received
•Influenced by amount of oxygenated
versus deoxygenated hemoglobin
•SpO2 determined
SpO2 Results
• 95 – 99% - normal
• 91 -94% - mild hypoxia
• Perform additional evaluation
• Administer supplemental oxygen
• 86 – 91% - moderate hypoxia
• Perform additional evaluation
• Administer 100% supplemental oxygen
• <85% - severe hypoxia
• Immediate intervention required
SpO2 Error Results

readings
• False readings possible
•
•
•
•
•
Carbon monoxide exposure – false high
High-intensity lighting near sensors
Hemoglobin abnormalities
Absent peripheral pulses
Hypovolemia; severe anemia
• SpO2 may be normal but the amount of
hemoglobin available is low
• Coordinate readings with patient assessment
Capnography
• Graphic recording or display of
measurement of expired CO2 over time
• End-tidal CO2 (ETCO2) – measurement of
CO2 concentration at end of expiration
• Provides information
•Systemic metabolism (production of CO2)
•Circulation
•Ventilation
How Does CO2 Circulate?
• CO2 is normal end product of
metabolism
• Transported by venous system to right
side of heart
• Pumped from right ventricle 
pulmonary artery  lungs and
pulmonary capillaries
• Diffuses into alveoli
• Removed from body via exhalation
Poor Perfusion States
• Shock, cardiac arrest, pulmonary
embolism, bronchospasm, incomplete
airway obstruction (ie: mucous
plugging)
•Perfusion decreased
•ETCO2 will reflect pulmonary blood
flow and cardiac output
•Will not reflect ventilation in poor
perfusion states
End Tidal CO2 Detector
• Contains pH sensitive chemically
impregnated paper to estimate ETCO2
level
• Color change is reversible
• Will reflect changes breath to breath
• Paper will be unreliable if
contaminated with acidic
drugs or gastric contents
Interpreting the ETCO2
• Yellow – indicates measured CO2 being
exhaled
• Evaluate after 6 breaths
• Tan – low levels of CO2 measured
• Misplaced tube or poor carbon dioxide
production
•Evaluate tube positioning
•Evaluate patient perfusion
• Blue or purple – no CO2 being measured
• Suspect unsuccessful intubation
ETCO2
• Applications
•Verify placement of endotracheal
tube
•Assess effectiveness of CPR
•CO2 levels fall abruptly at onset of
cardiac arrest
•CO2 levels begin to rise with
effective CPR

needle
Using a Prefilled Syringe
• Prepare the prefilled syringe
• Expel excess air
• Check for accuracy of volume
•Consider keeping 0.2 ml of excess
volume to account for the dead
space for each nostril (when
using one syringe for both
nostrils)
Attach MAD Tip to Syringe
• Suction nasal cavity as needed to clear blood
or secretions
•Clear nasal passages enhance absorption
of medication
• Deliver medication in divided doses
•Maximum of 1 ml per nares
Inserting MAD Nasal
• Control the patients head
with one hand
• Need to prevent
movement
• Gently but firmly place the
MAD nasal into one nostril
• Aim upward and toward
ear on same side
• Briskly compress the syringe
to deliver the drug as an
atomized mist into nares
Dispensing Mist
• Must briskly compress
syringe to convert liquid
drug to a fine atomized
mist
• Mist results in broader
mucosal coverage;
better chance of
absorption into the
blood stream than
drops that can run
straight back into the
throat.
MAD
• Region X will implement the MAD
beginning with Narcan
• Implementing MAD begins at the
completion of the 3rd day of department
training
• Document “IN” for route of
administration
• Will have the potential in the future to
add further medication using the MAD

• Question
• Do you need an IV established prior to
administration of medication?
• No, albuterol nebulizer should be started as
soon as possible
• Give verbal prompts to slow breathing down,
to take deeper breaths, and to eventually take
and hold a deep breath
