ACLS Flashcards
Post-Cardiac Arrest Cara
Temperature Management : between 32-36Celcius 89.6-95.2Farenheit for at least 24 hours
Oxygen: should titration of oxygen to lowest level possible to avoid oxygen toxicity. Approximately 94% oxygen or greater
Ventilation: start at 10/min and ventilate for capnography at around 35-45mmHg
Pressure: mean arterial pressure of at least 65mmHg is reasonable
Roles of Arrest
Airway Compressor Defibrillator Team Leader Medications Time/Recorder
Team Member
Ask for new task or role if unable to perform assigned task because it is beyond level of experience
Suggest an alternative drug dose in a confident manner
Question a colleague who is about to make a mistake
Team Leader
Clearly define roles for each person
Ask new intervention be done if it is higher priority
Ask for ideas of diagnoses
Confirm what members do and be clear about instructions
If Unsure about a Pulse
Start CPR because it can be more harmful to not do it if it is needed
BLS Assesment
Check Respnsiveness Shout for Help Check Breathing and Pulse Start CPR and Rescue Breathing Attach Defibrilator
Coronary Perfusion pressure
Aortic relaxation “diastolic”
- relates with both myocardial blood flow and ROSC
- one study showed that ROSC did not occur unless a CPP 15mmHg or greater was achieved
Quality Compresion
At least 2 inches
Rate of 100-120
Allow full chest recoil
Depth of Compressions
More often too shallow but too deep >2.4 inches has shown to decrease survival rate in cardiac arrest due to injuries
High Quality CPR
Compress chest hard and fast Allow complete chest recoil Minimize interruptions less than 10 seconds Avoid excessive ventilations Switch compressor every two minutes
Capnography
If less than 10mmHg then reasses quality of CPR
H’s and T’s
Hypovolemia Hypoxia Hydrogen Ion Hypo/hyperkalemia Hypothermia Tension Pneumo Tamponade Toxins Thrombosis (coronary and PE)
Tidal Volume of Adult
8-10ml/kg
Respiratory
Respiratory Rate below 6/min is considered hypoventilation and requires ventilation assistance
Resp Distress
Abnormal Respiratory Rate
Resp Failure
Inadequate Oxygenation
Resp Arrest
Absent Breathing
Tidal Volume for Patient not breathing
6-7ml/kg will suffice enough to rise the chest
BVM
If ventilations are being properly delivered and are adequate, providers may differ from an advanced airway
Excessive Ventilation
Can increase thoracic pressure, decreases venous return to the heart and diminishes cardiac output
Common Airway Obstruction
Loss of tone in the throats muscles. When the tounge falls to the back of the throat
Airway Obstruction
If obstructed and resp arrest occurs, start CPR and check mouth after every two minutes when going to give ventilations and remove with fingers if clearly visible
BVM device
Delivers approximately 600ml of volume and should see chest rise over 1 second
Suctioning
Suction force of 80-120mmHg is nescessary
Soft: used for mouth or nose and et deep suction
Ridged: suction oropharynx and thick secretions
Suction Measure
Ridged is the same as an OPA and the Soft is measured from nose, around ear to xiphoid process
Should not exceed more than 15 seconds
ACS Algorithm
Symptoms of ischemia=> abc’s 12 lead => titration oxygen if less than 90%, give 160-325 aspirin, nitoglycerine, morphine if pain not relieved by nitro
Reperfusion Goals
Door to Ballon 90minutes
Door to Needle (fibronolysis) 30 minutes
Chest Discomfort of Ischemia
- Uncomfortable Pressure, fullness, squeezing, pain in center of chest lasting several minutes
- Chest discomfort spreading to shoulders, neck, one or both arms or jaw
- Chest discomfort spreading to back or between shoulder blades
- Unexplained SOB with or without chest discomfort
Aspirin
Dose: 160-325mg causes near immediate and total inhibition of thromboxone
IF Pt has not taken aspirin, has allergies, or recent GI bleed
Nitroglycerine
Reduces ischemic chest discomfort
Cause reduction in LV and RV preload through peripheral arterial and venous dilation
1 spray, or dose, 400mcg every 3-5 minutes for ongoing symptoms
Total of three doses
BP > 90mmHg Systolic and HR IS 50-100/min
Inferior Wall MI
RV infarction may complicate an inferior wall MI because RV infarction rely heavily on RV filling pressures to maintain cardiac output
-Should not be given nitroglycerine or other Volume depleting drugs such as morphine or diuretics
Recent Phosphodiesterase Inhibitor Use
Avoid using nitroglycerine is suspected or known that patient has taken ED medications with 24-48 hours because may cause severe hypotension
Morphine
Opiate given for chest discomfort unresponsive to sublingual or nitro spray with medical control
PreHsopital notification of Stemi
Decreases time to treatment by 10-60 minutes
NonStemi
ST depression indicating injury or dynamic t wave inversion
Heparin
Given as adjunct to PCI therapy
Streptokinase
Fribronolytic drug used in MI in hospital
Stroke
87% ischemic
10% intracerebral
3% subarachnoid
Fibronolytic Therapy
Within 1 hour of hospital arrival time
Stroke Symtpoms
Confusion Trouble Speaking Sudden Weakness Dizziness Trouble Walking Severe Headache
Cincinnati
Facial Droop
Arm Drift
Abnormal Speech
If identified one of three signs then 72% chance is having a stroke
Establish Information
Last known normal time or seen
Bring a witness
Check BGL
Provide Oxygen to Stroke
If oxygen saturation is less than 94%
rTPA
Alteplase is a clot buster for stroke patients
Inclusion: onset within 4.5 hours and neurological deficit
Exclusion: age>80years old, taking anticoagulant, severe stroke, Hx of diabetes and stroke
Cardiac Arrest Algorithm
Start CPR Rhythm Shockable ? No, CPR 2 min, IO, Epi Yes, Shock, CPR 2 min, IO Rhythm? Shock, CPR 2 mins, Epi Rhythm? Shock, CPR 2 mins, ami Rhythm? Shock, CPR 2 mins, Epi
Shock Dosage
200j for defibrillator dose
Drug Therapy
Epinephrine 1mg Q 3-5mins
Amiodarone 300mg bolus and 150mg bolus
Shocking a Heart
Does not restart Heart. It temporarily stuns the heart and briefly terminates all electrical activity and if the heart is still viable, the heart will resume with its normal pacemaker
Rate Of Decline
For every minute of no CPR to cardiac arrest survival chances decrease by 7-10%
-with bystander CPR chances decline slower at 3-4%/minute
End Tidal Co2
Measure of blood delivered to lungs and readings less than 10mmHg mean ROSC is unlikely
Amiodarone
Vf/Vt
Blocks sodium and potassium channels
Lidocaine
No proven short term or long term benefits
- 1-1.5mg/kg bolus then consider .5-.75mg/kg to max of 3mg/kg
Mag Sulfate
Terminate torsades in patients with long QT interval
Loading dose of 1-2 G /5 minutes
Cardiac Arrest PEA
Consider H’s and T’s and focus on epi and compressions
Terminate CPR
If etco2 less than 10 after 20 minutes
Down time
Bradycardia
Bradycardia and heart blocks

Atropine .5mg Q3-5minutes max of 3mg
Dopamine 2-20mcg/kg/min titration
Epinephrine 2-10mcg/min
Transcutaneous Pacing
Indications: hypotension, ams, Shock, ischemic chest discomfort, acute heart failure (hemodynamically unstable)
Heart blocks, ventricular escape rhythms, new BBB
Contraindicated: severe hypothermia or asystole
-Conscious use analgesics for pain
-assess radial pulses and NOT carotid for mechanical capture
-once electrical captured set 2ma higher
-set rate 60-70bpm
-alternative is a chronotropic drug infusion (dopamine, epinephrine)
Tachycardia
Heart beating so fast cardiac output is reduced
Indications for Cardioversion
Sinus Tachycardia
Atrial Flutter
Atrial Fin RVR
V tach
Unstable
Have to use synchronized cardioversion
- hypotension
- ams
- Shock
- ischemic chest discomfort
- acute heart failure
- IF unstable do not waste time obtaining 12 lead to verify rhythm
Wide QRS stable
Without unstable then consider adenosine if regular and monomorphic, antiarrhythmic infusion
150mg/10min
Peds: 5mg/kg/20-30minutea
Polymorphic V Tach
Monitor will not allow synchronization of rhythm due to polymorphic and have to defibrillate at 200j dose
Synchronized
Synchronized to the highest point of the R wave to inhibit shocking the patient during an absolute refractory period causing possible asystole or other deadly rhythms
Doses
Narrow Regular 50-100j
Narrow Irregular 120-200j
Wide Regular 100j
Adenosine 6mg 12mg 12mg

Wide Regular Tachycardiac
Vtach with pulse, if stable, medications, unstable, cardiovert
Synchronized with Monitor
Make sure to reset “synchronized mode” after shock. Some monitors reset to unsynchronized in case lethal rhythm is produced from shock
SvT
Stable : make sure pathological, vagal maneuvers, adenosine, amiodarone, Shock if unstable
Adenosine
Contraindications:
A fib or flutter may accelerate rhythm
A fib RVR
Stable: vagal, .25 mg/kg bolus Cardiazem then .35mg/kg bolus and maintenance infusion of 5-15mg/HR
