What is a goal of NPPV regarding the respiratory rate?

The goal of non-invasive positive pressure ventilation (NPPV) regarding respiratory rate is indeed to achieve a rate of less than 30 breaths per minute. In patients requiring assistance with breathing, particularly those with conditions like COPD exacerbations or acute respiratory failure, a high respiratory rate can indicate distress and the need for intervention.

NPPV aims to provide support that helps reduce the work of breathing while allowing the patient to breathe more comfortably and effectively. By targeting a respiratory rate of less than 30 breaths per minute, NPPV helps to alleviate respiratory fatigue and ensure adequate ventilation. This threshold indicates a more stable respiratory status, minimizing the risk of hypercapnia and respiratory acidosis, which occur when the body retains carbon dioxide due to ineffective ventilation.

Maintaining this target not only indicates improvement in the patient's respiratory function but also guides clinical decisions regarding the continuation or adjustment of NPPV therapy. Therefore, the correct answer highlights an appropriate clinical goal that reflects the intended beneficial effects of NPPV in managing respiratory distress.
