Airway management
– maintenance of spontaneous ventilation– patient will waken from anaesthesia rapidly if agent delivery stopped– inhalational induction slow in the presence of an obstructed airway– apnoea may occur and patient…

Electricity – basics
An electric current is formed by the flow of charge carriers through a conducting material, similar to water flowing through a pipe. The base SI unit ampere (A) is defined…
Electrical safety
The graph above depicts the relationship between current, frequency and biological effect on sensation and muscle contraction. At high frequencies, greater current flow is required to cause muscle contraction and…
Capacitance, inductance and defibrillators
Capacitors are passive components that store electrical energy. The ability of the capacitor to store charge is its capacitance and is measured in farads (F). The capacitor consists of two…
Biological signals
A lead wire and voltmeter attached to the electrode allows measurement of the potential relative to a reference point. The reference point is usually a second skin electrode. Signals are…
CO2 analysis
The pH of the bicarbonate solution falls in proportion to the CO2 concentration, which is measured by the adjacent pH electrode. The Severinghaus electrode has a response time of 2–3…
Ionising radiation
Some isotopes, such as tritium, are unstable and undergo radioactive decay. This is a random process that follows an exponential pattern; the half-life of an isotope is the time taken…
