Professional physician scales have tremendous importance in the field of medical healthcare as well as in-home health care. Professional physician scales are generally used for measuring and documenting the body weight of an individual person. In upgraded scales, the body mass index of an individual can also be measured. Hospitals, doctor’s chambers, gymnasium, health clubs, physical therapist’s clinics, even in some of the drug stores- any place related to the healthcare field must contain different types.Any new-born baby should be weighed daily to track with his growth, any bed ridden patient should be scaled for proper medication, any patient needs to be scaled to determine the proper dose of anesthesia during operation, an athlete needs to be weighed daily to check how much muscle has been developed or how much fat has been drained. Even in some of particular athletics field, the contestants are categorized according to their body weight and hence in those games the importance of physician scales is really huge. And there are thousands of other cases where weighing machines have their tremendous importance.The accuracy of professional physician scales is really important in medical science. The nutrition chart and the diet for a newborn baby is solely determined by its body weight and hence the accurate daily measurement of the weight of a baby is utmost important. The doses of medicines prescribed to a patient largely vary according to the body weight of the patient and a wrong measurement of weight may result in a disastrous medical error.The professional physician scales can be broadly classified into two categories: mechanical and digital. The mechanical physician scale has the analog display with the use of an indicator. Mechanical devices do not need any external power source to be operated and also these devices are quite reliable for long-term uses. With proper calibration, the accuracy of the mechanical physician scales is very high, but their precision level is somewhat lower. The mechanical devices are the traditional devices and have been used from the beginning of the history of medical science.On the other hand, the digital scales are the newest devices and they are the result of the modern technologies. A digital scale has the digital display and displays an accurate result of the measured weight, sometimes to the hundredth of a pound. Obviously digital scales need necessary power from a built-in battery or from an external power source. The accuracy and precision of digital scales are quite high. However, since the digital scales are the electronic devices, there are chances of instrumental error and also these scales lose their efficiency after a long time of use.In the healthcare field, there are lots of companies that manufacture hundreds of different models. The models vary in their shape, size, facilities, displays and the technologies used. The constant research is going on in the healthcare field to achieve the higher level of professional physician scales. With the growth of the technology, more accurate, more precise measurements can be done using the modern professional physician scales.
