Transcript Specific Medical Emergencies

A
variety of pediatric medical problems can
activate the EMS system
 The majority of childhood medical
emergencies involve the respiratory system

Other systems may be involved
 Infectious
diseases may be caused by the
infection or infestation of the body by an
infectious agent

Virus, bacterium, fungus, or parasite
 Most
infections are self-limiting
 Some infections may be life threatening

Meningitis, pneumonia, and septicemia
Fever
 Chills
 Tachycardia
 Cough
 Sore throat
 Nasal congestion
 Malaise
 Tachypnea
 Cool or clammy skin
 Petechiae
 Respiratory distress

Poor appetite
 Vomiting
 Diarrhea
 Dehydration
 Hypoperfusion
 Purpura
 Seizures
 Severe headache
 Irritability
 Stiff neck
 Bulging fontanelle

 Take
all Standard Precautions
 Become familiar with the common pediatric
infections encountered in your area
 Previous exposure to disease and
vaccinations
 The
most common reason EMS is summoned
to care for a pediatric patient
 Your approach to the child with a respiratory
emergency will depend on the severity of
respiratory compromise
 Three



categories
Respiratory distress
Respiratory failure
Respiratory arrest
 Learn
in
to recognize the phase your patient is
 Mildest
form of respiratory impairment
 Increased work of breathing

Increase in respiratory rate


Frequently estimated
Should be measured for at least 30 seconds
 Normal
mental
status deteriorating
to irritability or
anxiety
 Tachypnea
 Retractions
 Nasal flaring (in
infants)
 Poor
muscle tone
 Tachycardia
 Head bobbing
 Grunting
 Cyanosis that
improves with
supplemental oxygen
 Occurs
when the respiratory system is not
able to meet the demands of the body for
oxygen intake and for carbon dioxide
removal
 Characterized by inadequate ventilation and
oxygenation
 Irritability
or anxiety
deteriorating to
lethargy
 Marked tachypnea
later deteriorating
to bradypnea
 Marked retractions
later deteriorating
to agonal
respirations
 Poor
muscle tone
 Marked tachycardia
later deteriorating
to bradycardia
 Central cyanosis
 The
end result of respiratory impairment
 The cessation of breathing

Typically follows a period of bradypnea and
agonal respirations
 Unresponsivenes
deteriorating to coma
 Bradypnea deteriorating to apnea
 Absent chest wall motion
 Bradycardia deteriorating to asystole
 Profound cyanosis
 Should
be based on the severity of the
problem
 Goals of management


Increasing ventilation
Increasing oxygenation
 Airway


Patency
Assure continued maintenance of the airway
 Breathing


If no improvement the patient should be treated
more aggressively
 Treatment
of late respiratory failure or
arrest



