Monitoring the health of the patient is very important. Both by the caregiver and the patient’s doctor. In my case, I had a stethoscope, sphygmomanometer (a device to measure blood pressure and pulse) and and oximeter which measure the percent of oxygen saturation in the blood and the pulse. The oximeter is very easy to use, just place it over a finger. The blood pressure device most common are over the arm (bicep) and over the wrist. I used over the wrist. Even though the arm reading is usually a little more accurate, the wrist measurement is easier to fasten.
For those unfamiliar with the ideal readings, a blood pressure reading of 120/80 and lower is good. Doctors become concerned when it is at or above 140/90. Oxygen content of 95% and higher is a good reading.
The device I used is over ten years old and may not be available.
