Ohmeda Biox 3760 Pulse Oximeter

The Ohmeda Biox 3760 Pulse Oximeter (OH3760P) is very similar in operation to the Nellcor N-200 and N-180, except that it includes the added feature of an printer which is mounted on the side of the unit. The printer can be configured to print the patient’s Oxygen Saturation % (SaO2) and pulse rate readings in one of six different user-selectable formats, including numeric-only and graphic formats. At the end of each reading, the printer will summarize the statistics and includes a histogram of the readings in graphic format.

Note that, like the Nellcor Pulse Oximeters, this unit describes functional oxygen saturation of hemoglobin and not fractional measurements. See the Nellcor Page for an explanation of the differences in functional and fractional readings.

The unit’s front panel includes an alarm limit key which allows the clinician to set the low SaO2 threshold (default is 90%); an alarm silence key which silences all alarms for 60 seconds; a liquid crystal display (LCD) which displays SaO2, pulse rate, status messages, and alarm messages; and the probe plug connector, where the finger probe is attached to the unit. The rear panel includes the charger connector port, where the AC adapter is plugged in.

The unit can operate on its internal rechargeable battery for approximately 7 hours without the printer and 3.5 hours with the printer. It can be recharged to 80% capacity in 4 hours and 100% capacity in 4.5 hours.

Pulse Oximeters

Pulse Oximeters are monitors that provide real-time measurement of a patient’s pulse rate and arterial oxygen saturation (the oxygen-carrying capacity of the blood’s hemoglobin, expressed as a percentage; normal is in the high 90’s). A disposable or reusable probe is placed on the patient’s finger (optional probes can be used on ear or tongue for some units.) The probe emits an infrared light from one side of the finger and captures the residual light that passes through the finger on the other side. The probe transmits this data to the monitor, which calculates the oxygen saturation of the blood. Used for patients with respiratory problems, and is required by law whenever a patient is under anesthesia. Note that these pulse oximeters measure Functional oxygen saturation, which is oxygenated hemoglobin expressed as a percentage of the hemoglobin that is capable of transporting oxygen. In contrast, some other laboratory instruments, such as blood gas analyzers or CO-oximeters, report Fractional oxygen saturation, which also measures dysfunctional hemoglobin. It is therefore not likely that the readings from these devices and the ones on a pulse oximeter will agree.
