Le ulse Oximeter isebenzisa I-Photoelectric Oxyhemoglobin Inspection Technology ngokuhambisana ne-Capacity Pulse Scanning & Recording Technology, engasetshenziswa ukukala ukugcwala komoyampilo womuntu kanye nezinga lokushaya kwenhliziyo ngomunwe. Idivayisi ifanele ukusetshenziswa emndenini, esibhedlela, kubha ye-oxygen, ukunakekelwa kwezempilo komphakathi nokunakekelwa ngokomzimba kwezemidlalo, njll. (Ingasetshenziswa ngaphambi noma ngemva kokuzivocavoca, kodwa ayinconywa ukuthi isetshenziswe ngesikhathi sokuzivocavoca).
