    Design a function for a patient monitoring system that validates composite vital sign readings by ensuring that the occurrence count of each threshold level (represented as a digit) does not exceed its actual threshold value to prevent false alarms. For example, in a reading of 22334, digit 2 appearing twice is acceptable since 2≥2, and digit 3 appearing twice is acceptable since 3≥2.
