An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
Cardiopulmonary resuscitation (CPR) is an emergency procedure consisting of chest compressions often combined with artificial ventilation, or mouth-to-mouth in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest.
Over the course of the study a 3.5 minute (51%) decrease in the interval between the 9-1-1 call and the application of the AED was observed. The study concluded that in the "7 suburban communities, police use of AEDs decreased time to defibrillation and was an independent predictor of survival to hospital discharge." [6]: 200
Choking, also known as foreign body airway obstruction (FBAO), is a phenomenon that occurs when breathing is impeded by a blockage inside of the respiratory tract.An obstruction that prevents oxygen from entering the lungs results in oxygen deprivation.

Trained health professionals have more limited use for AEDs than manual external defibrillators. [18] Recent studies show that AEDs does not improve outcome in patients with in-hospital cardiac arrests. [18] [19] AEDs have set voltages and does not allow the operator to vary voltage according to need. AEDs may also delay delivery of effective CPR.
In 1864, the first steam-driven nebulizer was invented in Germany. This inhaler, known as "Siegle's steam spray inhaler", used the Venturi principle to atomize liquid medication, and this was the very beginning of nebulizer therapy. The importance of droplet size was not yet understood, so the efficacy of this first device was unfortunately ...
This makes it easier to use the inhaler and helps ensure that more of the medication gets into the lungs instead of just into the mouth or the air. Proper use of a spacer can make an inhaler more effective in delivering medicine. [9] Spacers can be especially helpful to adults and children who find a regular metered dose inhaler hard to use.
