Can someone please tell me the differences between
defib, transcutaneous pacing (ie., in a code situation), and cardioversion. I'm referring to all during a code situation.
ok let me see if i can help.
defib (defibrillation) means to defibrillate some one who is in a shockable rythm in the hope that you will convert them back to some kind of normal rythm or normal electrical activity. the 2 shockable rythms in an arrest situation is VT/VF.
Pacing can be used when a patient may have had a complete or intermittant heart block but there is atrial activity being thrown off from them to pace. or effectively cling onto to pace. or it can also be attempted in patients with a PEA < 40. ive only seen this happen in very young patients who they will try anything on to save them.
cardio conversion is used for patients in AF. caution is taken here as we all know AF causes pools of blood to collect in the chambers of the heart due to abnormal functioning of the pumping mechanisms. therefore an echo must be carried out immediately prior to a DC conversion. if this does not happen and you convert a patient you will cause them to have a massive CVA. in an arrest situation cardiovert will only be used if a patient is haemodynamicaly unstable ie hypotensive, sob, hypoxic etc.
hope this has helped ive tried to explain it in simpler terms for you.
