- How defibrillators work explained simply - How Equipment Works
On this page of the website, you will learn the basic physics of how a defibrillator works In the end, you will be able to understand and draw the basic circuit of a defibrillator as shown below Please do not get a heart attack seeing this diagram! I will explain it step by step and you will understand it all
- What is defibrillation? - How Equipment Works
To defibrillate an heart, the electrical current passed through it needs to be large enough to silence all the heart muscle cells A small current would not work A major design requirement of defibrillators is to have the ability to provide the necessary large current How it does this will be explained to you soon
- How pulse oximeters work explained simply - How Equipment Works
Pulse oximetry uses light to work out oxygen saturation Light is emitted from light sources, which goes across the pulse oximeter probe and reaches the light detector If a finger is placed between the light source and the light detector, the light must now pass through the finger to reach the detector
- How capnograph monitors work explained simply. - How Equipment Works
When a patient has been given a muscle relaxant, the respiratory muscles are paralysed and cannot “move” The patient with a muscle relaxant is therefore connected to a ventilator, which does all the work However, when the relaxant has worn off, the respiratory muscles (diaphragm) can contract
- How anesthesia circle breathing systems work explained simply.
So how does the circle system come into the story of recycling? Well, the big advantage of the circle system is that it recycles expensive anaesthetic gases Let me explain how it does this During inspiration, an anaesthetic agent ( yellow dots ) goes into the patient
