Rapid Cardiopulmonary Assessment
Rapid Cardiopulmonary Assessment
1. Evaluation of general appearance (mental status, tone, responsiveness)
2. Physical examination of airway, breathing, and circulation (ABCs)
3. Classification of physiologic status
Rapid cardiopulmonary assessment should be accomplished in less than 30 seconds!

Late signs (decompensated)
— Weak central pulses
— Altered mental status

Septic Shock Is DifferentSeptic Shock Is Different
• Cardiac output may be variable
• Perfusion may be high, normal, or low
• Early signs of sepsis/septic shock include
— Fever or hypothermia
— Tachycardia and tachypnea
— Leukocytosis, leukopenia, or increased bands
Special Situations: Trauma Special Situations: Trauma
• Airway and Breathing problems are more common than Circulatory shock
• Use the ABC or assessment triangle approach plus
— Airway + cervical spine immobilization

•Differentiate shock from hypotension
•Distinguish compensated from decompensated shock
•Outline appropriate shock management

•Shock can occur with increased, decreased, or normal blood pressure.
Recognition of Shock
Compensated: Decompensated:
• Normal level of consciousness
• Altered level of consciousness (ALOC)
• Tachycardia • Profound tachycardia, or bradycardia
• Normal or delayed perfusion
• Delayed perfusion
• Normal or increased BP • Hypotension
Management of ShockManagement of Shock
Interventions:• Open airway • Provide
supplemental oxygen
• Support ventilation• Shock position• Vascular access/fluid
resuscitation• Vasopressor support

SVT
Sinus Tachycardia
SVT versus Sinus Tachycardia
SVT versus Sinus Tachycardia
SVT (Supraventricular Tachycardia)
Sinus Tachycardia
• Vague history of irritability, poor feeding
• History of fever, vomiting/diarrhea, hemorrhage
• Cardiac monitor: QRS complex narrow; R to R interval regular; no visible P waves
• Cardiac monitor: QRS complex narrow; R to R interval varies; P waves present and upright
• HR > 200 beats/min • HR < 220 beats/min
Treatment PrioritiesTreatment Priorities
• Supplemental oxygen• Obtain IV access• Convert rhythm based on hemodynamic stability
–Stable: vagal maneuvers or adenosine–Unstable:
• IV /IO access obtained - adenosine• No IV/IO and unconscious - synchronized
cardioversion
•Blow-by oxygen administered
• IV started
•Adenosine 0.1 mg/kg (1mg), given rapid IVP with 5 ml saline flush
•Five seconds of asystole, followed by conversion to NSR
Conclusion
• Cardiovascular compromise in children is often related to respiratory failure, hypovolemia, poisoning or sepsis.
• Management priorities for shock include airway management, oxygen and fluid resuscitation.
• Treat rhythm disturbances emergently only if signs of respiratory failure or shock are present.

• Confirmation of tracheal tube position strongly recommended
• Monitoring of quality improvement important
Complications of Prehospital Tracheal Intubation

Confirmation of Tracheal Tube Placement in Pediatric Advanced Life Support
Confirmation of Tracheal Tube Placement in Pediatric Advanced Life Support
• Visualize tube through cords
• Assess breath sounds, chest rise bilaterally
• Secondary confirmation:
— Oxygenation (oximetry)
— Exhaled CO2 (capnography)
Tube ConfirmationTube Confirmation
• No single confirmation device or examination technique is 100% reliable
• Detection of exhaled CO2 is reliable in patients weighing >2 kg with a heart rate
• Exhaled CO2 can be helpful in cardiac arrest• Confirmation of tube position is particularly
important after intubation and after any patient movement
Insertion of the Laryngeal Mask Airway in ChildrenInsertion of the Laryngeal Mask Airway in Children
• The LMA consists of a tube with a cuffed mask at the distal end.
• The LMA is blindly introduced into the pharynx until resistance is met; the cuff is then inflated and ventilation assessed.
Use of Laryngeal Mask Airway in Pediatric Advanced Life SupportUse of Laryngeal Mask Airway in Pediatric Advanced Life Support
• Extensive experience with pediatric and adult patients in the operating room
• An acceptable alternative to intubation of the unresponsive patient when the healthcare provider is trained
• Contraindicated if gag reflex intact• Limited data outside the operating room
(Class Indeterminate)
Intraosseous Needles Are Recommended for Patients >6 Years of Age
Intraosseous Needles Are Recommended for Patients >6 Years of Age
• Successful use of intraosseous needles has been documented in older children and adolescents
• Devices for adult use are commercially available
• “No one should die because of lack of vascular access”
Drug Therapy for Cardiac ArrestDrug Therapy for Cardiac Arrest
• Epinephrine: the drug of choice— Initial IV/IO dose: 0.01 mg/kg (tracheal: 0.1 mg/kg)— Do not routinely use high-dose (1:1,000)
epinephrine— Good at getting heart rates to return— Poor long term outcome

Resuscitation of the Newly Born Outside the Delivery Room
• Priority: Establish effective ventilation• Provide chest compressions if heart rate is <60 bpm despite
