The Ohmeda Biox 3740 Pulse Oximeter differs from the Ohmeda 3760 by delivering a graphic wave form directly on the display which indicates the current, real-time Oxygen Saturation % (SaO2) and pulse rate readings. This wave form shows the quality and strength of patient signals, and can be changed to have either the graphic information or numeric information dominant. The 3760, on the other hand, delivers trend data at preset intervals. Although the 3740 has no printer function, it will store up to eight hours of data, which can be downloaded to a computer through a serial port for analysis.
The unit’s front panel includes an menu key which allows the clinician to set the low SaO2 threshold (default is 90%); the high SaO2 (default is OFF); volume levels and response time; time and date; and a calibration and diagnostic mode. The unit uses the same probes and AC adapter as the 3760.
The unit can operate on its internal rechargeable battery for approximately 3.5 hours. It can be recharged to 80% capacity in 4 hours and 100% capacity in 6.5 hours.
