![]() ![]() Humidity, flows, and their measurement are well dealt with, together with the effects we see in different systems such as Venturi and Coanda. The chapter goes on to describe the applications of pressure to valves and measuring devices in anaesthesia and usefully the implications of siphon effects. Worked examples are helpful, for example, delivery of pressure from different sized syringes with the same force applied to the plunger. Considering waves, the differences between sound and electromagnetic waves are well described, together with an interesting section summarizing harmonic series and Fourier analysis. Definitions are highlighted in summary boxes, although sometimes these are expressed in terms that are perhaps too simple, but generally are very helpful.ĭiagrams such as the series showing work done by a ventilator vs work done in the lung are a useful sequence. These are all easily understandable with an appropriate level of simple supporting equations and explanation. The initial chapters cover the basic physics of atoms, simple mechanics, energy and power, temperature and heat, waves, and pressure. The size of the book inevitably means that there are a few areas that could be more fully dealt with as described below, but overall it is a very effective text. This is a very wide brief, but the book copes with this very well in a relatively small package. ![]() ![]() It describes physics that apply to anaesthesia. ![]()
