Gaskell-Greff Method

Gaskell - Greff method

The Gaskell-Graff method is a method for determining heart rate in animals, which was proposed in 1900 by William Gaskell (1847-1914) and Leopold Graff. This method is based on the measurement of arterial pulsatility and is used to assess cardiac output and overall cardiac function.

The principle of the method is as follows: a cuff is placed on the artery that needs to be examined, which creates pressure that exceeds the normal pressure in the artery. The cuff is then gradually deflated, and in the process the pressure in the artery drops. When the pressure in the artery reaches a certain level, the artery expands, which leads to pulsation. Arterial pulsation rate is an indicator of cardiac output, i.e. the amount of blood the heart pumps per minute.

The Gaskell-Greff method is widely used in experimental physiology and medicine to assess the function of the heart and cardiovascular system as a whole, as well as to determine the effectiveness of treatment of cardiovascular diseases.



Gaskell–Greff method

Gaskell-Graeff (1846-1923) invented microkinesiotherapeutic method of mechanical action on bones through pressure. In his opinion, accelerated ossification and restoration of bones are ensured by the action of weak shock loads on them. This technique, in fact, underlies kinesiotherapy as a method of movement therapy. Before the invention of transplantation, it was possible to find a common language between anthropology and anatomy, which considered the human skeleton primarily as an object of study, and restorative medicine, which already knew how to cope with many ailments. Since the technique was developed for the rehabilitation of accident victims, the treatment of open fractures and previously identified dislocations was not particularly difficult for its authors.
