What clinical indicators suggest readiness for extubation?

Readiness for extubation is determined by several clinical indicators that reflect the patient's ability to maintain adequate ventilation and oxygenation without the need for mechanical ventilation. The correct choice highlights key factors that are essential for assessing whether a patient can safely be extubated.

Positive arterial blood gas (ABG) results indicate that the patient's gas exchange is adequate, showing acceptable levels of oxygen and carbon dioxide. This is critical as it demonstrates that the patient can breathe adequately on their own without relying on the ventilator.

Stable hemodynamic status suggests that the patient’s cardiovascular system can support the stress of extubation and subsequent recovery. Unstable hemodynamics could lead to complications and should be addressed prior to attempted extubation.

Adequate protective airway reflexes are vital for ensuring that the patient can effectively clear secretions and maintain airway patency after extubation. Patients need the ability to cough and protect their airways from aspiration, which is crucial for reducing the risk of post-extubation complications.

In contrast, increased respiratory rate, tachycardia, and agitation signify distress, indicating that the patient may not be ready to be extubated. Similarly, decreased FiO2 and high PEEP settings could reflect poor lung function and
