The word monitor originated from the Latin word “monere”, meaning “to warn.” The primary role of monitoring devices is to alert the physician of changes in patient’s conditions and modify the therapeutic interventions based on the information gleaned from the monitors. Pulse oximetry, sometimes called the fifth vital sign, is a noninvasive method of measuring hemoglobin saturation (SpO) by using a light signal transmitted through tissue. A low SpOcan provide warning of 22hypoxemia before other warning signs such as cyanosis or a change in heart rate become clinically apparent. (Please choose one best answer)
