EQUIPMENT AND TECHNOLOGY

We have the ability to record directly from pulse oximeters to computer using analog or serial connections.

For analog output, we can record up to 14 devices. Our inputs require BNC connectors, so adapters will likely be necessary. We will need information on the type of connector used. We assume 0-1 or 0-10 volts for a saturation range of 0-100%. If devices are different, we will need to know ahead of time, but can probably accept any voltages.

For serial device, we use standard RS-232 connectors and can record up to 16 devices. We expect the oximeter to have a female connector. If the connectors are different, we will need to arrange for adapters.

Because different oximeters send different ASCII data, we will need to have the oximeters in advance to be able to properly translate any serial data. We will also need information on the serial connection protocol, including baud rate, and the number of data bits.

Blood Gas Analyzers

Radiometer ABL90

On the ABL90 FLEX blood gas analyzer you get 17 parameters from samples as small as 65 μL in just 35 seconds. That is only about a third of the time required by other compact analyzers.

Data Recording

Labview

We record directly from pulse oximeters to computer using LabVIEW (National Instruments) using 16 analog or 16 serial connections.  This data can then be exported into easily accesible excel files for your analysis.

Other Testing Capabilities

Our laboratory facility has capacity and extensive experience with a wide variety methods for studying human physiology. These include measurements of SpO2, PaO2, PaCO2, end-tidal gases, cerebral oximetry, trans-cranial doppler, jugular venous bulb saturation, central venous oxygen saturation, cerebral spinal fluid, and invasive hemodynamic parameters. Measurements can be done in healthy human subjects at sea-level or altitude with controlled levels of hypoxia, hypo/hypercarbia, anemia (isovolemic hemodilution), as well as induced carbon monoxide and met-hemoglobin levels.  All studies are conducted following UCSF IRB approval.  Our currently approved protocols may be reviewed here.  We are also open to discussing new study ideas.  Please contact us with any questions you may have by visiting our Contact Page.
