Cardiac Arrest Flashcards
5 Main Reasons for Capnography in Cardiac Arrest
- Verify advanced airway placement
- Identify advanced airway displacement
- Evaluate CPR quality
- Identify return of spontaneous circulation (ROSC)
- Determine when ROSC is unlikely
What should you see after 20 minutes of Advanced Cardiac Life Support (ACLS)?
- ETCO2 levels < 10 mmHg associated with fatality
- ETCO2 levels > 25 mmHg associated with survival
What should ETCO2 be with good CPR?
12-15 mmHg
What should you look for in the patient when the ETCO2 is increasing?
Signs of ROSC
What should you look for in the patient when the ETCO2 is decreasing?
- Chest compressor fatigue
- hyperventilation
- pneumothorax
- airway obstructing
- advanced airway displacement
Surge of electric energy delivered to the heart
Defibrillation
What are the 3 P’s in automated external defibrillation?
- Power
- Pads
- Plug in
What should you do if the AED indicates shock advised?
- Continue chest compressions while charging
- Rescuer pushes button to deliver shock while ensuring nobody is touching the patient
- Restart CPR immediately with new rescuer
- Look for signs of life while CPR continues
How long is the breathe delivered for?
Over 1 second
How long should you be off the chest during CPR?
No more than 5-10 seconds at a time
When should you initiate breathes durimg CPR?
First breathe at 28 compression, second at 30
O2 to be delivered via BVM during CPR
350-500 mL
Underlying factors causing cardiac arrest
- AEIOUTIPS
- hypovolemia
- hyper/hypothermia
- hyper/hypoglycemia
- Hypoxia
- acidosis
- hyper/hypokalemia
- Toxins
- Tamponade
- Tension pneomo.
- Thrombosis trauma
What should you do if cardiac rhythm and pulse are restored?
Reassess ABC’s
What are the 3 H bombs?
- Hypoxia
- Hyperventilation
- Hypotension
