
Emphysema

Pathophysiology

Exposure to Noxious Substances
Exposure results in the destruction of the walls of the
alveoli.
 Weakens the walls of the small bronchioles and results
in increase residual volume.


Increased Risk of Infection and Dysrhythmia
Emphysema

Assessment


 Prolonged
expiration and
rapid rest phase.
 Thin.
 Pink skin due to
extra red cell
production.
 Hypertrophy of
accessory muscles.
 “Pink Puffers.”

RESPIRATORY
Chronic Bronchitis

Pathophysiology
Results from an increase in mucus-secreting cells in
the respiratory tree.
 Alveoli relatively unaffected.
 Decreased alveolar ventilation.



Command at
Mass-Casualty
Incidents
Incident Commander (IC)


Coordinates all scene activities
Also called Incident Manager (IM) or
Officer in Charge (OIC)
The first on-scene unit must assume command
and direct all rescue efforts at a mass-casualty
incident (MCI)
Singular vs. Unified Command

Singular command
One person coordinates the incident.
 Most useful in smaller, single-jurisdictional incidents.


Unified command

Managers from different jurisdictions share
command.

Fire, EMS, law enforcement
Establishing Command



First arriving unit establishes command.
Assign command early in an incident.
Establish a command post.

Management of a Patient
in Labor



Transport the patient in labor unless delivery is
imminent.
Maternal urge to push or the presence of
crowning indicates imminent delivery.
Delivery at the scene or in the ambulance will be
necessary.
Field Delivery





Set up delivery area.
Give oxygen to mother and
start
Drape mother with toweling
from OB kit.
Monitor fetal heart rate.
As head crowns, apply gentle
pressure.
Suction the mouth and then
the nose.
Clamp and cut the cord.
Dry the infant and keep it
warm.
Deliver the placenta and
save for transport with the
mother.

Neonatal Resuscitation



If the infant’s respirations are below 30 per minute
and tactile stimulation does not increase rate to
normal range, assist ventilations using bag valve
mask with high-flow oxygen.
If the heart rate is below 80 and does not respond to
ventilations, initiate chest compressions.
Transport to a facility with neonatal intensive care
capabilities.
Causes of Bleeding
During Pregnancy




Abortion
Ectopic pregnancy
Placenta previa
Abruptio placentae
Abortion





Termination of pregnancy before the 20th
week of gestation.
Different classifications.
Signs and symptoms include cramping,
abdominal pain, backache, and vaginal
bleeding.
Treat for shock.
Provide emotional support.
Ectopic Pregnancy


Assume that any female of childbearing age
with lower abdominal pain is experiencing an
ectopic pregnancy.
Ectopic pregnancy is life-threatening.
Transport the patient immediately.
Placenta Previa




Usually presents with
painless bleeding.
Never attempt vaginal
exam.
Treat for shock.
Transport
immediately—
treatment is delivery
by
c-section.
Abruptio Placentae





Signs and symptoms
vary.
Classified as partial,
severe, or complete.
Life-threatening.
Treat for shock, fluid
resuscitation.
Transport left lateral
recumbent position.
Abnormal Delivery Situations
OB / GYN (Abnormal
Deliveries)
Breech
Breech Presentation


The buttocks or both feet present first.
If the infant starts to breath with its face
pressed against the vaginal wall, form a “V”
and push the vaginal wall away from infant’s
face. Continue during transport.
OB / GYN (Abnormal
Deliveries)
Prolapsed Cord
Prolapsed Cord





The umbilical cord precedes the fetal presenting part.
Elevate the hips, administer oxygen, and keep warm.
If the umbilical cord is seen in the vagina, insert two
gloved fingers to raise the fetus off the cord. Do not
push cord back.
Wrap cord in sterile moist towel.
Transport immediately; do not attempt delivery.
OB / GYN (Abnormal
Deliveries)
Limb Presentation
Limb Presentation
With limb presentation, place the
mother in knee–chest position,
administer oxygen, and transport
immediately. Do not attempt delivery.
Other Abnormal Presentations




Whenever an abnormal presentation or position of
the fetus makes normal delivery impossible, reassure
the mother.
Administer oxygen.
Transport immediately.
Do not attempt field delivery in these
circumstances.
Other Delivery Complications
OB / GYN (Abnormal
Deliveries)
Multiple Births
Multiple Births



Follow normal guidelines, but have additional
personnel and equipment.
In twin births, labor starts earlier and babies
are smaller.
Prevent hypothermia.
OB / GYN (Abnormal
Deliveries)
Meconium
Meconium Staining


Fetus passes feces into the amniotic fluid.
If meconium is thick, suction the
hypopharynx and trachea using an
endotracheal tube until all meconium has
been cleared from the airway.
Maternal Complications of
Labor and Delivery
Postpartum Hemorrhage



Defined as a loss of more than
500 cc of blood following delivery.
Treat for shock as necessary.
Follow protocols if applying antishock
trousers.
Uterine Rupture






Tearing, or rupture, of the uterus.
Patient complains of severe abdominal pain and will
often be in shock. Abdomen is often tender and
rigid.
Fetal heart tones are absent.
Treat for shock.
Give high-flow oxygen.
Transport patient rapidly.

Causes
 Assessment
 Treatment

Anatomical and physiological considerations
in the infant and child.
a. In the supine position, an infant’s or child’s
larger head tips forward, causing airway
obstruction.
b. Placing padding under the patient’s back and
shoulders will bring the airway to a neutral or
slightly extended position.
General Approach to
Pediatric Assessment
Basic Considerations



Much of the initial patient assessment can be
done during visual examination of the scene.
Involve the caregiver or parent as much as
possible.
Allow to stay with child during treatment and
transport.
Scene Size-Up





Conduct a quick scene size-up.
Take BSI precautions.
Look for clues to mechanism of injury or nature
of illness.
Allow child time to adjust to you before
approaching.
Speak softly, simply, at eye level.
Suctioning




Decrease suction pressure to less than 100
mm/Hg in infants.
Avoid excessive suctioning time—less than 15
seconds per attempt.
Avoid stimulation of the vagus nerve.
Check the pulse frequently.
Inserting an oropharyngeal airway in a
child with the use of a tongue blade.
Ventilation







Avoid excessive bag pressure and volume.
Obtain chest rise and fall.
Allow time for exhalation.
Flow-restricted, oxygen-powered devices are
contraindicated.
Do not use BVMs with pop-off valves.
Apply cricoid pressure.
Avoid hyperextension of the neck.
Circulation
Two problems lead to cardiopulmonary
arrest in children:


Shock
Respiratory failure

(hypoperfusion) in a child.

Croup
 Epiglottitis


Lower airway distress
Asthma
 Bronchiolitis

a. Croup and
b. Epiglottitis
Positioning of the child with epiglottitis.
Often there will be excessive drooling.
The child with epiglottitis should be
administered humidified oxygen and
transported in a comfortable position.
