Cardiac Assessment

NREMT EMT NREMT PARAMEDIC

Definition

Systematic cardiovascular evaluation: pulse, BP, skin signs, capillary refill, and cardiac emergency recognition.

Common Errors

Critical errors in prehospital application of cardiac assessment:

Failing to reassess after intervention. Vital signs must be rechecked every 5 minutes for unstable patients
Incorrect medication dosing. Always use length-based estimation (Broselow tape) for pediatric patients
Tunnel vision on one finding while missing the complete clinical picture
Not communicating changes to receiving facility during transport

Clinical Significance

In prehospital care, understanding cardiac assessment can mean the difference between a positive patient outcome and a critical miss. A construction worker stung by wasps, developing urticaria, stridor, and hypotension. Anaphylaxis: epinephrine 0.3mg IM, IV fluids, diphenhydramine, albuterol for bronchospasm.

Related pharmacology: naloxone at 0.4-2mg IV/IM/IN, titrate to respirations, indicated for Opioid overdose.

Historical Context

The modern EMS system in the United States traces to the 1966 "Accidental Death and Disability" white paper (NAS/NRC). Understanding of cardiac assessment has advanced significantly with evidence-based protocols. The NREMT, founded in 1970, standardized certification levels. Current ACLS and PALS guidelines are updated every 5 years by the AHA based on the International Liaison Committee on Resuscitation (ILCOR) evidence review.

Equipment & Tools

Equipment used in cardiac assessment assessment and treatment:

BVM: Bag-valve-mask for manual ventilation. Available sizes: Adult (1500mL), Pediatric (500mL), Infant (250mL)
Pulse oximeter: Measures SpO2 via infrared absorption through capillary bed. Available sizes: Finger clip, Earlobe, Pediatric wrap
King airway: Supraglottic blind-insertion airway device. Available sizes: Size 3 (4-5 ft), Size 4 (5-6 ft), Size 5 (over 6 ft)

Frequently Asked Questions

What assessment tools help evaluate cardiac assessment?▼

For cardiac assessment: SAMPLE: evaluates Signs/symptoms, Allergies, Medications, Past history, Last intake, Events; scoring is Mnemonic for patient history gathering. APGAR: evaluates Appearance, Pulse, Grimace, Activity, Respiration; scoring is 0-10 at 1 and 5 minutes, under 7 needs intervention.

What vital signs should be monitored when assessing cardiac assessment?▼

For cardiac assessment: GCS: 15 is normal, under 8 = severe TBI. respiratory rate: 12-20 breaths/min. heart rate: 60-100 bpm. Reassess every 5 minutes for unstable patients.

What protocol applies to cardiac assessment in prehospital care?▼

For cardiac assessment: Sepsis recognition: qSOFA of 2 or more (altered mentation, RR 22+, SBP 100 or less) then IV fluids 20 mL/kg then early antibiotics if ALS
