What is a miscalibrated sensitivity likely to affect during a PSG?

A miscalibrated sensitivity primarily impacts signal clarity during a polysomnography (PSG) study. Sensitivity in this context refers to the ability of the equipment to detect small signals among noise. When the sensitivity is not set correctly, either too low or too high, it can lead to distorted or unclear signals. This means that vital information regarding the patient's sleep stages, movements, and any potential sleep disorders may be compromised. Proper signal clarity is essential for accurate interpretation of the PSG data and for diagnosing any sleep-related issues.

The other aspects mentioned, such as patient comfort, study duration, and technologist workload, may be influenced indirectly by equipment issues or operational practices, but they are not directly affected by sensitivity calibration in the same way that clarity of the signals is. Therefore, clarity of signals is the most critical concern resulting from miscalibrated sensitivity.
