Evaluation
Recognize pre-arrest changes
Agonal respirations or apnea
Weak pulses
Decreasing mental status
Precautions
CPR should not interfere with acute life-threatening measures
Unless medial
Cardiac Arrest
was concurrent with
Trauma
or massive blood loss, CPR is unlikely to offer benefit
CPR interferes with diagnostic
Ultrasound

Finger Thoracostomy
,
Emergency Thoracotomy
Key initial diagnostics

Airway Obstruction
Early definitive airway (
Advanced Airway
,
Cricothyrotomy
)
Tension Pneumothorax
Needle Thoracostomy
or
Finger Thoracostomy
(followed by
Chest Tube
)
Massive Hemothorax
Autotransfusion
of blood from
Chest Tube
Surgical repair (for >1500 ml blood loss or 200 ml/h for >3 hours)
Open chest wound
Occlusive Dressing
and
Chest Tube
Cardiac Tamponade
Emergency Pericardiocentesis
Emergency Thoracotomy
(
Penetrating Trauma
)
Commotio Cordis
Blunt Chest Trauma
at the
Cardiac Cycle

Arrhythmia
(
Ventricular Fibrillation
,
Asystole
)
Greatest chance of survival is for early cardiac
Defibrillation
within first 5 minutes
Massive Hemorrhage
Obtain two large bore (16 to 18 gauge)
Intravenous Access
sites (or
IO Access
)
Obtain central venous access as available
Control Bleeding
Apply direct pressure, then
Tourniquet
,
Suture
or
Topical Hemostatic Agent
Massive Blood Transfusion
May require 4 or more units
pRBC
within first hour
Replace 1 unit FFP per
pRBC
unit and 1 unit apheresis
Platelet
s per 8
pRBC
units
Epidural Hematoma
Trephination (burr hole) if imminent
Hernia
tion signs
Emergent surgical decompression
Management
Cessation of efforts
Blunt
Trauma
No pulse, pupillary activity, organized EKG activity or cardiac motion on
Ultrasound
after 10 minutes
Pentrating
Trauma
Consider
Emergency Thoracotomy
if presenting with
Asystole
and
Cardiac Tamponade
No pulse, pupillary activity, organized EKG activity or cardiac motion on
Ultrasound
after 15 minutes
Prognosis
Predictors of Survival
Initial cardiac rhythm
Signs of life on hospital arrival (11.5% survival vs 2.6%)
Pupil
lary response (highly predictive of survival)
Glasgow Coma Scale
(GCS) >3
Cardiac activity on
Bedside Ultrasound
Absence of cardiac activity is an indication to cease
Resuscitation
Organized cardiac rhythm
Ventricular Fibrillation
(90% survival)
Pulseless Electrical Activity
(60% survival)
Asystole
(low survival rate)
