A Detailed Protocol for Physiological Parameters Acquisition and Analysis in Neurosurgical Critical Patients

The overall goal of this procedure is to acquire and analyze multiple physiological parameters in neurosurgical critical patients. This method can help answer key questions in clinical data monitoring and analysis of yield such as mean Icp value, ABP and Icp derived parameters. The main advantage of this technique is that it can be each achieve long-term, high-frequency monitor data acquisition and analysis.

We first had the idea for this method when we were trying to collect and analyze critical neurosurgical patients’long-term continuous physiological data and realized that there are few specific devices that a simple for clinicians in their daily clinical work. Begin by connecting the Icp monitoring machine with the bedside monitor via a specific communication cable. Adjust the reference in the patient’s bedside monitor so that the data from the bedside monitor are in accordance with the Icp monitoring machine.

Perform an arterial line placement on the patient’s left or right radial artery. Next connect the arterial line with the baroreceptor. Then connect the pressure transducer with the patient’s bedside monitor via a communication cable.

Finally, zero adjust the bedside monitor so that the measured blood pressure coincides with the actual value. Begin by connecting the patient’s bedside monitor with the data collecting and storing device via a network cable. Press the power button to turn on the data collecting device.

Next, enter the patient’s information including the name, ID, diagnosis and initial Glasgow Coma Scale, or GCS. Click the save and start monitoring button to start data collecting and storing. Finally, click the turn off button on the screen at the end of the data acquisition and enter the final GCS.

First, dump the stored data to a U disc through universal serial bus interfaces, or USB, on the host. Then, enter a username and password to log into the analysis server. Click the Create New Record button and select the data file in the U disk to start uploading.

Then, wait for around 10 to 20 minutes before the data are analyzed, depending on the size of the data file. Next, click on the Detail button of each record to see the results. Click on the chart viewing to see the final diagram.

Drag the timeline to see more detail. Finally, click the Scattergram button to see the distribution of the parameters. This new multimodal monitoring and analyzing system is capable of recording and plotting key parameters of the neurosurgical critical patient.

As the timeline is adjusted, more detail can be shown for each parameter. Further, this system can analyze the relationship between any two parameters, for example, Icp and PRx, as shown here. This patient’s PRx has a variation from minus 0.7 to one and the lowest PRx is reached when his Icp is 10 millimeters of mercury.

While attempting this procedure, it is important to remember to perform the zero adjustment properly to ensure that the data collected coincides with actual value. After its development, this technique paved the way for clinicians in neurosurgical critical care units department to monitor physiological parameters, analyze the current clinical status and predict the prognosis in neurosurgical critical patients. After watching this video, you should have a good understanding of how to acquire and analyze multiple physiological parameters in neurosurgical critical patients.
