    Write a function that analyzes pairs of patient vital sign readings to determine how many pairs of measurements, when XORed together, result in an even value, indicating potential physiological correlations. Each reading is represented as a binary-encoded integer value from various monitoring devices, and identifying these pairs helps detect patterns that could signal emerging health complications.
