Which issue is commonly associated with patient monitoring devices?

Sensor calibration issues are commonly associated with patient monitoring devices because these devices rely on accurate sensor readings to assess a patient’s condition. Sensors must be calibrated regularly to ensure that they provide precise and reliable data. This is crucial since inaccurate measurements can lead to misdiagnosis or inadequate treatment, impacting patient safety and care quality.

In practice, calibration may be affected by various factors such as environmental conditions, age of the device, or changes in the patient's physiology. Therefore, biomedical equipment technicians must be vigilant in regularly checking and calibrating these sensors as part of maintenance protocols.

The other options do not reflect issues typically related to patient monitoring devices. For example, while battery life can be a concern, it is not as pressing an issue as calibration, which directly impacts patient outcomes. Similarly, maintenance is always necessary for medical devices, and while algorithms do have bugs, they typically can be updated and do not represent a typical, persistent problem in the same way that calibration does.
