1. Can defibrillation be performed during oxygen administration?
During defibrillation treatment for patients wearing oxygen tube, the oxygen tube should be properly placed, not near the electrode sheet or electrode plate, so as to prevent fire or explosion. Defibrillation can be performed when the oxygen delivery tube is properly placed to ensure that oxygen does not leak out.
2. How do drowning patients get defibrillation?
The drowning patient is covered with water, so during rescue, it is necessary to move him to a dry ground, clean the defibrillation site, keep the defibrillation site dry, and then defibrillation.
3. Is shock defibrillation first or cardiopulmonary resuscitation first during CPR?
The new CPR guidelines point out that when AED can be obtained immediately, defibrillators should be used as soon as possible for witnessed adult cardiac arrest. Rationale: Although there are many studies comparing a specific length of time before electric shock (usually 1 ½ Minutes to 3 minutes) and electric shock as soon as the AED is ready, but there is no difference in the prognosis of the patients. Cardiopulmonary resuscitation should be performed while placing the AED electrode piece until the AED can analyze the patient’s heart rhythm.
4. Can the patient defibrillate with a pacemaker?
Yes. However, the pacemaker may be damaged when the patient with pacemaker is treated. It is recommended that the patient check the pacemaker after treatment.
5. Do you need to unplug the cardiac electrical lead during defibrillation?
It needs to be unplugged unless the defibrillator with defibrillation protection lead is provided.
6. Can you defibrillate during infusion?
Not allowed in principle. Especially the steel needle for infusion, but in an emergency, such as the patient’s life is in danger, the venous channels of CVC, PICC and indwelling needle need defibrillation. It is difficult to eliminate VF or restore the heart rhythm to the perfusion state only by relying on the basic CPR.
7. Can other tests be performed during defibrillation?
When the defibrillation monitor is connected with the patient, no functional examination can be carried out to avoid accidental electric shock to the patient.
8. How many indications are there for defibrillation?
The indications of asynchronous defibrillation include ventricular fibrillation, pulseless ventricular tachycardia and unsynchronized ventricular tachycardia; Indications for synchronous defibrillation include atrial fibrillation and paroxysmal supraventricular tachycardia; Others include hemodynamic disorders such as heart failure and blood pressure decline, and ineffective drug treatment.
9. What does synchronous and asynchronous defibrillation mean?
Asynchronous defibrillator (without R wave): it is not synchronized with the patient’s own R wave during defibrillation, and can be used in ventricular fibrillation. The patient’s autonomic rhythm does not need to be considered during electrical stimulation, so it is called asynchronous defibrillation. Synchronous electric defibrillation: it is mainly used for atrial fibrillation. During electric shock, the release of cardioversion pulse shall be synchronized with the patient’s heart beat to make the electric stimulation signal fall into the ventricular absolute refractory period (30ms after the start of R wave), so as to avoid ventricular fibrillation caused by stimulation falling into the ventricular vulnerable period near the peak of T wave.
10. How to choose energy during defibrillation?
Single phase wave 360j, two-phase wave 200J. Children weigh 2-4 times. Eight times the size.
