During EEG procedures, high interelectrode impedance can lead to:

High interelectrode impedance can significantly impact the quality and reliability of EEG readings, leading to a range of issues. One of the primary concerns is the potential loss of important data. When the impedance between electrodes is too high, it can create a barrier for the proper transmission of electrical signals from the scalp to the EEG machine. This results in incomplete or distorted data collection, which can compromise the diagnostic value of the EEG.

Additionally, high impedance can reduce picture clarity. An EEG is essentially a visual representation of electrical activity in the brain, and high impedance can introduce noise and artifacts, making it more challenging to interpret the waveform patterns accurately. This can obscure critical features of the EEG and lead to misinterpretations.

Unstable readings are another consequence of high interelectrode impedance. Fluctuations in impedance can lead to inconsistent signal quality, resulting in an unstable or erratic display of brain activity. This instability can complicate the interpretation and analysis of the EEG, making it difficult for healthcare professionals to draw reliable conclusions from the data.

Considering these factors, high interelectrode impedance can lead to loss of data, reduced clarity, and unstable readings, all of which contribute to the challenges faced during EEG procedures. Therefore, the correct answer encompasses all these
