Uses refined noise-reducing hardware and a unique patented software algorithm. Instead of relying on a voltage threshold to determine a pulse, it analyzes a digitized signal at a rate of 120 times per second, and compares it to previous pulse data. These

Portable pulse oximetry monitoring system includes: 3301 Monitor; 1818 Operation/Service Manual; (3) Alkaline C Cell Batteries.

Low cost, spot-check device displaying SpO2, pulse rate, signal strength and Pulse amplitude Index (PI). This device delivers reliable performance, meeting the needs of health care providers in primary care environments. Responds to challenging environmen
