INITIAL ASSESSMENT
DETERMINE ON ALL PATIENTS:
1.
Age
2.
Chief complaint.
3.
Previous medical history.
4.
Weight
5.
Medications
6.
Allergies
7.
Immunizations
8.
Source of routine care.
NOTE:
1.
Vital signs must be individualized for each patient.
2.
Any patient seen at a health care facility earlier and brought back
for return visit at the ER is a source of concern.
BASIC and ADVANCED LIFE SUPPORT
1.
Establish unresponsiveness.
a. Gently shake patient.
b. Raise your voice to awaken the patient.
2.
Call for help.
3.
Position patient on a firm flat surface.
4.
Open the airway: Head tilt – chin lift method; jaw thrust maneuver
if with cervical spine injury.
Note: A posteriorly placed tongue is a common cause of airway
obstruction.
5.
Assess breathing. Look, feel and listen.
 Observe for chest rise
 Listen for breath sounds
 Feel for expired air
6.
Establish a seal.
a. Infant – apply Mouth to Nose and Mouth.
b. Older child – apply Mouth to Mouth; pinch nose
7.
Give two slow breaths using enough volume to cause the chest to
rise. If chest does not rise – obstructed airway.
8.
Begin rescue breathing if breathing is not noted.
9.
Assess pulse for cardiac function.
a. Infants < 1 year – use brachial or femoral arteries.
b. Older children – carotid artery
10. Begin chest compression if no pulse present.
a. Infant <1 year – compress one finger width below the imaginary
line between the nipples on the sternum
b. Older children and adolescents – compress over the lower half
of the sternum
11. Coordinate compression and breathing – 5:1
compression/ventilation ratio.
12. Airway obstruction
a. Infants < 1 year –
i. Do five back blows with the child straddled over the
rescuer’s arm.
ii. Then do five chest thrusts at the location described for
chest compression.
iii. Repeat sequence until relieved.
b. Older children – Perform Heimlich maneuver or abdominal
thrust. Repeat until obstruction is relieved.
Note: Endotracheal intubation – best way to manage the airway
during CPR.
ETT size = width of the 5th finger or diameter of the
nares.
= 4 plus (Patient’s age) / 4
