Routine Medical Care
12-lead EKG (ASAP)
Aspirin 160 - 325mg¹ PO (chewed)
Notifying the receiving ED as early as possible should take high priority when infarct is suspected. Transport to a hospital with cardiac catheterization capabilities.
Acute Coronary Syndromes include unstable angina and ST elevated myocardial infarction (STEMI)
Stable Angina
NTG 0.4 mg² SL repeat q 3 min PRN
X 3 doses with SBP >100 and/or Apply 1 inch NTG paste TD
AMI (STEMI)
NTG 0.4 mg² SL repeat q 3 min PRN
X 3 doses with SBP >100 and/or Apply 1 inch NTG paste TD
Unstable Angina
NTG 0.4 mg² SL repeat q 3 min PRN
X 3 doses with SBP >100 and/or Apply 1 inch NTG paste TD
Morphine Sulfate 2-4mg IV / IO q 2min. PRN to MAX of 10mg
OR Fentanyl 25-50mcg IV/IN/IM q 2min. PRN to MAX of 200mcg
¹ Aspirin (ASA) is contraindicated in pts with current or recent GI bleeding & known ASA allergic reactions . ASA is relatively contraindicated in patients with history of asthma and Medical Control is to be contacted prior to administration.
² Nitroglycerin (NTG) is contraindicated in patients who have taken Viagra or Levitra within the past 24 hours (Cialis in the past 48 hours). NTG SL tablets and NTG SL spray may be used interchangeably.
•Age and cardiac risk factors (defined in the Protocol Preambles) are a key evaluation tool in this protocol. Major riskfactors should be documented on the EMS Run Report.
•If the administration of one NTG results in a substantial decrease in blood pressure, discontinue further NTG use; thisresponse may be indicative of an MI involving the right ventricle. This hypotension usually responds well to a fluid bolus (NS). A common finding associated with a right sided inferior MI is ST elevation in V4R with bradycardia.
•Treat life-threatening arrhythmias per the appropriate protocol before initiating this ACS protocol.
• Consider a right sided 12-lead EKG (V4R) for suspected Inferior STEMI (leads II, III, AvF).
•Ventricular ectopy typically does not require treatment unless the ectopic beats are greater than the number of regular(non ectopic) beats and / or a patient is hemodynamically unstable.
•Paramedics treating patients within this protocol should minimize on scene time to 15 minutes for STEMI.
Stable Angina • can be controlled by NTG & lifestylemodification • pain at rest is unusual• precipitating factors are usually known andpredictable • relieved by rest or NTG
Unstable Angina (considered an ACS) • pain at rest• pain does not follow a pattern or the usualpain pattern worsens • usually not relieved by rest or medication• highly suggestive of impairment tovasculature and/or myocardium
Acute Coronary Syndrome (ACS)
Chest Pain not relieved & SBP ≥ 100mm/Hg

ASYSTOLE / PEA
ASYSTOLE / PEA
AHA ACLS 2015 updates places special attention on the value of chest compressions & minimizing interruptions to < 5 seconds. Manual chest compression rate = 100-120/minutes pausing only to verify
cardiac rhythm & check pulses every 2 minutes. Mechanical chest compressions are per manufacturer’s recommendations. Ventilations are withheld during the first 8 minutes unless otherwise indicated.
Confirm absence of pulse, apnea & no signs of life. Immediately begin effective chest compressions
Attach Monitor without interrupting Chest Compressions; confirm Asystole / PEA
Consider Carotid or Femoral Doppler to confirm absence of pulse
· Establish IV/IO access ASAP without interrupting chestcompressions
· Epinephrine 1mg IV/IO ASAP repeat q 3 - 5min
Search & treat for possible contributing factors3
Hs & Ts
< 5 sec pause q 2 min for rhythm / pulse check
Only if acidosis is suspected (i.e. prolonged down time)Sodium Bicarbonate 1mEq/kg*
3Contributing Factors:· Hypoglycemia – treat with Dextrose 50%· Hyperkalemia – Calcium Chloride 8mg/kg for known hyperkalemia· OD - of tricyclic antidepressants Sodium Bicarb and/or Narcan 2mg IV for narcotic OD· Tension pneumothorax - Needle Decompression or Heimlich Valve Kit· Hypothermia – avoid rigorous movement of patient; especially if patient regains pulse. Excessive movement could cause V-Fib or
V-Tach. This is rare but when it occurs the VF/VT is almost always refractory.· Hypovolemia – Fluid bolus* With proper and effective CPR, acidosis, in the absence of prolonged down time, usually does not occur and therefore, SodiumBicarbonate should not be needed.
· Effective chest compressions &Early defibrillation takes priorityover ANY OTHER TREATMENT.
· Withhold ventilations during the first 4cycles of chest compressionsUNLESS indicated by nature of arrest(choking, peds, lung disease, etc)
· IV / IO access & First line medications(Early Epinephrine administration haspriority over any advanced airway.
· ET without ventilations is a means ofsecuring the airway if resources allow
· Pause for ≈ 5 sec q 2 min to verifyEKG & pulse check
After 4 cycles of chest compressions, begin ventilations (unless indicated earlier) at 1 per 6 – 8 sec / 8 -10 min

Bradycardia (Symptomatic)
Atropine 0.5mg IV/IO may repeatq 3 - 5 min to a max of 3 mg. If pt is, or becomes unstable do not delay T.C.P.
Obtain 12-lead EKG
Supportive care; monitor for s/s of symptomatic bradycardia.
Contact Med-Control IF needed
TCP, set rate b/t 70-80 bpmStart at 50 milliamperes (mA), increase output until
capture is achieved¹ then add 2 mA for safety margin.
Dopamine 2 to 10mcg/kg/minEpi 2 – 10 mcg/min
Pre-medicate with Versed 2.5 - 5 mg IV/IO if possible
¹ Widening of QRS and a broad T wave after each spike.
•Symptomatic bradycardia is defined as pulse < 60 beats per minute (bpm) with a SBP <100mm/Hg, SOB, altered mentalstatus, and/or other signs of hypoperfusion. (Well conditioned athletes could have HR < 60 & SBP < 100 normally)
•Patients presenting with possible cardiac related chest pain and/or STEMI should NOT receive atropine, unlesshemodynamically unstable, prior to consulting with Medical Control.
•Transplanted hearts will not respond to Atropine; TCP is the treatment of choice
• TCP is the treatment of choice for 2nd degree type II and 3rd degree AV heart blocks with serious S/S. Contact MedicalControl if no serious S/S exist. Atropine is NOT indicated for AV blocks at this level.
AV Block AV Block -- 22°° IIII or 3or 3°° NonNon--SymptomaticSymptomatic
If symptomatic prepare for TCP
Each patient will obviously present differently therefore, it is unrealistic to indicate when TCP is or is not needed. Paramedics should use their clinical judgment to make that decision; if in doubt call Medical Control.

CARDIAC ARREST
· HISTORY:· Estimated down time; Events leading to arrest, DNR / Living Will, Underlying Causes, SAMPLE History, Crime Scene
SIGNS AND SYMTOMS:Unresponsive, No Signs of Life,
Apneic, Pulseless
Rhythm Shockable?
TEAM APPROACHTeam Leader Designates Assignments and Actions
Defibrillate at Maximum Energy Level3 &
Immediately Resume Effective Chest Compressions x 2 Minutes
Pause q 2 min for < 5 sec to determine pulse & rhythm
IV / IO Access Without Interrupting Chest Compressions ASAP
Epi 1:10.000 q 3 – 5 minutes ASAP during the beginning of chest
compressions cycles for optimum effectiveness
Pearls:·
1 Respiratory / Ventilatory management becomes a higher priority if indicated as cause for arrest (Choking, Pediatrics, COPD, etc.) otherwise an Oral Pharyngeal Airway with a NRB @ 15 LPM is appropriate. Also, endotracheal intubation connected to BVM & 100% O2 without ventilation is appropriate to secure an airway without compromising chest compressions
· 3 Regardless of defibrillator model, initial and subsequent joule settings will be at maximum energy
· High quality chest compressions with minimal interruptions have a greater impact on patient outcome than anyintervention.
· Ventilations (when indicated) should be no more than 8 – 10 per minute. Avoid hyperventilation.

• Rales / Rhonchi (gurgles)
• TachycardiaBlood Pressure
& Early 12 lead EKG
to assess for STEMI
• Nitroglycerine (NTG) 0.4mg SL, & may repeat q 5min as long as SBP >100mmHg,
ALSO • NTG paste 1in. TD may be used to supplement NTG
SL per SBP >90mmHg
Dopamine Infusion 5 – 20 mcg/kg/min or
Norepinephrine 1 – 10 mcg/min
BVM’s are NOT only for apneic
patients! Positive Pressure
Ventilation (PPV).
¹ Hepatojugular reflux indicates right sided heart failure. With the patient sitting at a 30° angle, palpate the abdomen over the liver lightly, if the jugular veins rise ≈ 4 cm = positive reflux.
• Consider myocardial infarction as a cause of pulmonary edema—transport to facility with cardiac catheterization lab.
• In the elderly and recently institutionalized patients consider pneumonia.
• Avoid NTG in patients that have taken Viagra or Levitra in the past 24 hours, or Cialis in the past 48 hours
• Consider the use of quantitative ETCO2 as a diagnostic tool.
Contact Medical Control immediately after the starting the infusion. Because
CPAP has the potential to further decrease blood pressure, contact
Medical Control for the use of CPAP.
Systolic BP > 100mm/Hg with pulmonary edema and/or R.R. ≥ 30
Systolic BP < 90 – 100mm/Hg

Resuscitation should not be attempted in the following situations prior to contacting Medical Control:
Lividity Rigor mortisBody decomposition, decapitation, hemi-corpectomy or incineration Any reason to believe CPR is not indicated or desired, especially with known terminal
illness.Presence of legal documents (“Advance Directives,” “Living Wills,” POLST
(Physicians Orders for Life Sustaining Treatments) or “DNR”) stating resuscitative efforts be withheld.
CRIME SCENE PRESERVATION
EKG electrodes may be placed posteriorly or on limbs whenever necessary.
Every effort possible should be made to preserve a crime scene
DOCUMENTATION
Asystole EKG strip in at least two leads should be included in the EMS Run Report along with proper documentation.
Document the scene findings including: medications, medical history, last time pt was spoken to, position found, skin temp, pupils, any trauma or deformity etc…
Contact Medical Control for DNAR & time of death
If EMS arrives to find CPR in progress on a patient who is clearly deceased or a patient who meets the criteria listed above in the blue box, CPR can be stopped with orders from Medical Control.For traumatic DNAR, see the Adult Traumatic Prehospital Termination of Resuscitation Protocol.

• If upon successful electrical conversion of VF / VT prior to having administered an anti-arrhythmic, contactMedical Control before administering 150mg Amiodarone over 10 minutes.
• Titrate Dopamine 5-20mcg/kg/min or Norepinephrine 1-10mcg/min to MAP > 80 / SBP > 90 mm/Hg
• The condition of the post-resuscitation patients fluctuates rapidly, they require close monitoring and post ROSCcare may be planned with online Medical Control
• Hyperventilation is a significant cause of hypotension by decreasing venous return to the heart in post-arrestpatients; this must be avoided at all costs.

Post Termination Procedures:
This patient/body becomes property of the Coroner’s office once pronounced.
ETT / Supraglottic Airways must remain in place. IV / IO’s cannot be taken out.ECG electrodes & Defib pads remain. Do not remove decompression needles (if applicable).
Continue resuscitative efforts.Package patient and transport to the receiving facility.Advise medical direction of any additional changes in the patient’s condition.
¹ Quantitative capnography is defined in the Protocol Preambles.
² Deterioration of a safe scene in which the EMT’s are in danger takes priority over scene time on cardiac arrests. If the scene has become too
dangerous to provide patient care, law enforcement must be dispatched with documentation reflecting such on the run report.
Termination of Resuscitation does not apply in public venues (areas that cannot be readily secured by law enforcement or the coroner) or at any time the medics feel their safety is compromised.
