Aim:
To evaluate layperson (university student) ability to use an automated external defibrillator (AED).
Design:
A repeated measures quasi-experimental study with non-probabilistic sampling and a control group was carried out.
Scope:
Teacher training degree students at the University of Santiago de Compostela (Spain).
Participants:
The sample consisted of 129 subjects (69% women and 31% men), between 19-47 years of age (mean 23.2±4.7 years). As inclusion criterion, the subjects were required to have no previous knowledge of AED.
Interventions:
Times to apply defibrillation with an AED to a mannequin were recorded untrained (T0), after a theoretical and practice explanation lasting less than one minute (T1), and 6 months after the training process (T2).
Main Variables Of Interest:
The primary endpoint was the time taken to deliver a defibrillation discharge. The "improvement effect" variable was defined by the absolute time difference between T1 and T0, while the "degree of forgetfulness effect" variable was defined as the absolute difference between T1 and T2.
Results:
The mean times were T0=67.7s; T1=44.2s; T2=45.9s. The time to apply defibrillation was reduced after explanation training (T1
Conclusions:
Easy handling of AED was demonstrated, since untrained people were able to deliver a discharge. Defibrillation time was reduced after brief training. This time barely increased after 6 months.

01:25Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Assessing the apical pulse is a critical nursing procedure, particularly indicated for:

01:11Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
