Final Answer:
Indications for using a nasal cannula include mild to moderate hypoxemia, postoperative care, and palliative care. Troubleshooting involves checking for proper fit, ensuring the tubing is unobstructed, and confirming adequate oxygen flow.
Step-by-step explanation:
Nasal cannulas are commonly used in medical settings for various indications. They are suitable for patients experiencing mild to moderate hypoxemia, such as those with respiratory distress or chronic obstructive pulmonary disease (COPD). Additionally, they are employed in postoperative care to assist patients in their recovery by providing supplemental oxygen. Moreover, nasal cannulas are utilized in palliative care situations to alleviate respiratory distress and ensure comfort in patients with end-stage illnesses.
Troubleshooting issues with a nasal cannula involves several steps. Firstly, ensuring a proper fit is essential to prevent air leakage and optimize oxygen delivery. Secondly, checking for any obstructions in the tubing, such as kinks or blockages, is crucial as these can impede the oxygen flow. Lastly, confirming the prescribed oxygen flow rate and ensuring it matches the actual flow rate are essential to guarantee the patient receives the intended amount of oxygen.
This process helps healthcare providers address common problems encountered while using nasal cannulas, ensuring effective oxygen delivery to patients in need.
