Using refined noise-reduction hardware (digital processing) and a unique patented software algorithm Serial Auto Correlation (SAC™), the V3304 is able to look at pulse oximetry data in a whole new way. This innovative oximeter technology analyzes a digital signal at a rate of 120 times per second and compares it to previous pulse data. These pulses are constantly stored and updated, and used as dynamic templates to determine the validity or invalidity for newly encountered pulsatile signals. The V3304 offers the same advanced features as the V3402, see page F46, but in a table top package with extended data storage capabilities. Three user-selectable averaging modes are available, visual and audible indicators for SpO2 and pulse rate, an 8 segment LED bar indicator for pulse strength as well as high and low limit adjustable alarms for SpO2 and pulse rate. Low priority alarms warn the user of system setup malfunctions such as a disconnected probe. The audible indicators and alarms vary in rate and pitch to indicate changes in pulse rate and SpO2 level, respectively.
Animal IDs from 0-99 are used by the V3304 to delineate multiple animal data measurements. An optional serial printer, BS4 72-3173, is available which can be used to output animal data in continuous datal log mode (every 5 seconds) or trend mode (every 4-30 seconds). Trend data continues to be stored even when data is being printed using the data log mode. The V3304 can store up to 90 hours of trend data for up to 99 individual animals. The trend storage interval is user selectable from 4-30 seconds. Decreasing the trend storage interval decreases the maximum length of time data can be stored in memory. Output of data to a computer requires the use of BS4 72-3166 printer interface cable and BS4 72-3155 PC adapter cable. The V3304 Pulse Oximeter comes with an instruction manual, AC adapter/charger, BS4 72-3157 5 foot oximeter extension cable, BS4 72-3254 small reflectance probe and the BS4 72-3256 small to medium Y-Clip probe. The unit is powered by an internal rechargeable lead acid battery. Other pulse oximeter probes and accessories are available, see to the right.
