What is the initial pressure?
Opening pressure is the initial value of cerebrospinal fluid (CSF) provided during submission of lumbar puncture (LP). Several variables may affect the initial CSF, including the patient's position during testing. The lumbar test values that fall below or above a normal range may indicate infection or illness. It is important to note that the results may vary depending on the laboratory used.
Often performed to evaluate pressure in the central nervous system can be used as a diagnostic tool to determine the presence of infection. The test can also be performed to detect bleeding, swelling or arterial dysfunction. According to the MD website, the normal opening pressure range should fall between 90 and 180 mm with water for a healthy adult.
The lumbar puncture puncture requires that the individual turns into an almost fetal position. While laying on the side with his feet tucked next to his body, the targeted area in the lower back is disinfected and ready for lumbar punkci. The targeted piercing area is usually between the third and fourth vertebrae that is located slightly above the tail. A hollow needle for collecting CSF sample for analysis is introduced into the lower spine.
Several fine elements can affect the reading of the initial pressure. Placement of the patient, for example, with increased posture, can cause CSF pressure to increase. If the breathing of the individual is fast or its blood pressure is slightly increased, the results of the opening pressure will be stunned. During the lumbar puncture piercing, it is essential that the individual lay on his side without any slope or height of the head or legs.
Once the needle is inserted, a device called a pressure gauge is used to monitor and evaluate the speed at which CSF is collected. The pressure of the initial collector of the CSFON or the opening pressure is recorded together with the CSF liquid presentation. For exampleincreasing to the backbone column or infection.
If the opening pressure is recorded above 180 mm, this may indicate infection, inflammation or some other health problem. Several other conditions, including epilepsy, Reye syndrome and encephalitis, can be detected with lumbar puncture. Reading the initial pressure that drops below normal may indicate a decrease in cerebrospinal fluid, which may be caused by an obstacle in the spinal column.
