The week of learning about bio-medical equipment begins by learning about blood pressure meters. To be able to fix a piece of equipment one must know how it works. Mackenzy, Elie, Jhonny and Jivenson are pleased to become professional sphygmomanometer technicians. They reported yesterday that they took a test and successfully passed with flying colors! Of course I had no doubt they would. The improvement of the world begins with the empowerment of the individuals!
