Monitoring arterial blood gas (ABG) results is critical for a patient in noninvasive ventilation as it directly reflects the effectiveness of the therapy. ABG analysis provides valuable information on the patient's respiratory status, including oxygenation and ventilation efficiency. Key parameters such as partial pressure of carbon dioxide (PCO2) and partial pressure of oxygen (PO2) can indicate how well the patient is ventilating and whether the noninvasive support is improving gas exchange.

Changes in ABG values can signal the need for adjustments in therapy or further medical interventions, helping to evaluate if the noninvasive ventilation is successfully treating conditions like acute respiratory failure or exacerbations of chronic obstructive pulmonary disease (COPD). This real-time feedback is essential in managing the patient's respiratory care effectively during noninvasive ventilation.

Other options, like monitoring urine output or electrolyte levels, can provide useful information about a patient's overall health and fluid balance but do not directly assess the effectiveness of respiratory support. Body temperature monitoring is also important for detecting infections or other complications but does not serve as a primary measure of ventilatory effectiveness.
