Prison is a dangerous place, and always has been. The danger to both prisoners and guards has always been high, and for that reason certain precautions are always taken to ensure that violence does not break out. Prisons have their own classification which depends on the criminals that are housed in them. They range from minimum security to maximum. In either level, one thing does not change is minimizing exposure of inmates to each other. This limitation is going to vary depending on the prison system. This separation is based on minimizing prison guards" risk with inmates to the speed at which certain activities can be handled. These activities include anything from meals, to exercising, to the amount of time it takes for medical evaluations.
Medical examinations at prisons are conducted periodically throughout the year for inmates for various reasons. The prison system in the United States has been designed to minimize the health risks for inmates, but that does not mean that there is absolutely no risk. In order to do so, all prisons have their own medical wards. These wards have their own doctors and nurses who tend to inmates.
One new medical device found at prisons is a pulse oximeter. A pulse oximeter, also known as a pulse ox by some medical professionals, is a device used to measure the blood oxygen saturation and pulse rate of an individual. Prison medical wards had a pulse oximeter before, but it was in a different format. They were bulky table top types. Now a pulse oximeter
is designed to clip onto one"s fingertip and it smaller than most cell phones.
A new pulse oximeter
makes is easier for a medical professional to take the readings of a patient within seconds, and move onto the next patient.
