Which intervention is important to implement for a patient who has undergone cardiac surgery and is experiencing respiratory failure?

In the context of a patient who has undergone cardiac surgery and is facing respiratory failure, providing emotional support and encouraging relaxation can play a significant role in their recovery. After cardiac surgery, patients may experience anxiety and stress, which can exacerbate respiratory issues and compromise oxygen saturation levels. Emotional support helps to reduce anxiety and fosters a calm environment, making it easier for the patient to breathe and potentially improving overall respiratory function.

Addressing a patient's emotional well-being can also promote better compliance with other therapeutic interventions, such as deep breathing exercises. When patients feel supported emotionally, they are more likely to engage in necessary activities that can aid in their recovery, including taking deep breaths and participating in rehabilitation.

While other interventions like encouraging deep breathing and cough are indeed important, the initial priority in the setting of respiratory failure post-surgery is often to stabilize the patient's emotional state, which can indirectly support their respiratory efforts. Increasing fluid intake may assist in secretion clearance, but it must be balanced with the patient's needs, especially post-surgery when fluid management is crucial. Physical therapy is beneficial but should be tailored to the patient's condition; hence, limiting their engagement without sufficient reasoning may not always be justified.
