Image Description: This photograph gives us a close up and detailed look at a tonometer, a device commonly used to measure blood pressure and pulse rate in patients suffering from heart problems. By practicing what is called arterial tonometry, doctors are able to monitor these variables in patients for long periods - sometimes even permanently - via a completely noninvasive method, all thanks to this handy little device. This particular tonometer appears to not only deliver results on the screen, but perhaps audibly, as well, as indicated by the onboard speaker, surely proving to be a real boon to those with degraded eyesight.
