Codes/End of life Flashcards
Cardiac arrest survivability
Only 15% of cardiac arrest patients survive til discharge
After 85 yo, only 6% of patients survive til discharge
Of those that survive, 25% of them will need to go to a ltc facility, and 50% will be discharged home
How long can it take for the code team to arrive at the bedside?
3-5 minutes
When should you call a code blue?
Immediately if any patient becomes unresponsive, apneic, or pulseless (check carotid pulse)
What should you do after initiating code blue?
Yell out for help and begin initiating CPR. Responding code team members will announce their roles upon entering the room. A staff member that is not participating in the code should call the patient’s PCP.
Effective chest compressions during CPR
Chest compressions should be performed at a rate of 100-120/min (“Staying Alive”)
Push hard, at least 2 inches in depth
Allow for full chest recoil
If the client is not on a hard surface utilize a backboard for CPR
When alone do not wait for a backboard to be placed. It can be placed when further help is available
Switch compressors approximately every 2 minutes, sooner if fatigued
Chest compressions cause air to be expelled from the chest and oxygen to be drawn into the chest due to elastic recoil
Ventilation requirements are lower during cardiac arrest that normal
Oxygen supplied by passive delivery should be sufficient for several minutes after the onset of cardiac arrest in a client with a patent upper airway
Research supports the delay of ventilation until additional help arrives
Effective airway management during CPR
2 ventilations for every 30 compressions
Use a bag-mask device (ambu bag) with the flow at 15 L/min
Each ventilation should cause the chest to visibly rise
On oropharyngeal can be placed to ensure airway patency
Bag-mask ventilation is most effective when performed by two trained providers
Prepare to assist with intubation
How strong is monophasic defibrillation?
Monophasic begins at 360 J
How strong is biphasic defibrillation?
Biphasic begins at 120-200 J depending on the manufacture.
Proper use of hard paddles during defibrillation
When using hard paddles you must apply a conducting medium to prevent burns
Proper use of soft patches during defibrillation
Patches must have full contact with the client’s bare skin
Avoid pacemaker sites or transdermal patches
During and after defibrillator administers a shock
Announce the shock and make sure everyone is clear
Immediately after the shock resume chest compressions
-Don’t delay to recheck the rhythm or pulse
-Resumption of a normal rhythm won’t initially produce enough cardiac output for adequate perfusion
Continue CPR for five cycles or about 2 minutes
Recheck should occur with change of compressors
Check for return of spontaneous circulation (ROSC) by checking the carotid pulse
What are shockable rhythms?
Ventricular tachycardia and Ventricular fibrillation
What are nonshockable rhythms?
Pulseless electrical activity and asystole
Ventricular tachycardia (V-tach)
Life threatening rhythm arising from an excitable ventricular focus in the tissue distal to the bifurcation of the bundle of His
It is initiated by a premature ventricular contraction (PVC)
Heart rate is greater than 100 beats per minute
P waves usually not recognizable, PR interval not discernable, QT interval not measurable
Ventricular fibrillation (V-fib)
Rapid, disorganized depolarization of the ventricles
No organized electrical impulses, no coordinated atrial or ventricular contraction or palpable pulse
Multiple ventricular sites initiate electrical impulses
P wave, PR intervals, QRS complexes, and QT intervals are all absent
Pulseless electrical activity
Heart muscle loses its ability to contract even though cardiac electrical activity is present
Represents an organized rhythm outside of V-tach or V-fib. Usually bradycardia or heart block
Client has no detectable pulse or blood pressure
Initiate CPR per ACLS guidelines
Clinical outcome is usually poor unless a reversible cause is identified and treated
Asystole
Complete termination of all cardiac electrical activity
Client has no detectable pulse or blood pressure
Initiate CPR per ACLS guidelines
Reversible causes of code blue
Hypovolemia Hypoxia Hydrogen ion (acidosis) Hypo-/hyperkalemia Hypothermia Tension pneumothorax Tamponade, cardiac Toxins Thrombosis, pulmonary Thrombosis, coronary
Medications during CPR
Medications are secondary to high-quality CPR and rapid defibrillation Epinephrine IV/IO dose -1 mg every 3 - 5 minutes -First dose after second shock Amiodarone IV/IO dose -First dose 300 mg bolus -Second dose 150 mg bolus -First dose after third shock
What does the primary nurse do during a code?
Assesses client, calls code, provides chest compressions, provides leader with client information
