What are the required alarms for NIV?

The required alarms for Noninvasive Mechanical Ventilation (NIV) are crucial for ensuring patient safety and effective treatment. The correct choice encompasses essential alarms that alert caregivers to significant issues that could compromise the patient's ventilation.

Battery failure, circuit disconnect, and loss of power are critical alarms because they address potential interruptions in the device's functioning. A battery failure alarm indicates that the power source may not be sufficient for continued operation, potentially leading to a complete cessation of ventilatory support. A circuit disconnect alarm alerts staff when there is a break in the ventilatory circuit, which can lead to inadequate gas delivery to the patient. Lastly, a loss of power alarm is vital, as it informs caregivers immediately if the device cannot operate, ensuring prompt action to prevent respiratory distress.

In contrast, while other options included alarms that are important for certain settings, they may not represent the essential or universally required alarms for NIV. For example, high-pressure limits and low tidal volume alarms are indeed significant, but without the immediate risk of power failure, disconnects, or battery issues highlighted in the correct answer, the safety of the NIV setup could be at greater risk.
