Are you an athlete? Do you do those long marathons? Are you a triathlete? Are you an ironman or an ironwoman?
In these modern times there is no reason why an athlete should not be able to monitor his vital signals. A Nonin Onyx 9550 Pulse Oximeter (nonin 9550) is an excellent choice to monitor your pulse and oxygen levels.
Being an athlete not withstanding, simply if you are pulmonary handicapped a pulse oximeter can keep you informed as to the state of your oxygenation. Computerization and miniaturization has made great products possible.
Monitoring your vital signs, performance, and other metrics is important to the power athlete. Getting one of these meters is an essential option. Why not take advantage of what used to be done in a doctors office in the comfort of your home.
