While ventilating an intubated patient, you notice a shark fin waveform on capnography and difficulty in ventilations. What should you do?

• A. Increase ventilatory rate
• B. Administer albuterol
• C. Intubate the patient again
• D. Apply positive end-expiratory pressure (PEEP)

Answer: (B)

In this scenario, observing a shark fin waveform on capnography indicates the presence of airflow obstruction, commonly associated with conditions like asthma or COPD exacerbations. This waveform suggests that the patient is having difficulty exhaling, which manifests as ineffective ventilation and a potentially rising end-tidal CO2 level. Administering albuterol is the most appropriate response because it is a bronchodilator that helps to relax bronchial smooth muscle and open airways, decreasing resistance to airflow. This action can alleviate the airway obstruction indicated by the shark fin waveform and improve ventilation, correcting both the waveform appearance and the difficulty you’re experiencing while ventilating. Understanding the context of the other options can help clarify why they may not be as suitable. Increasing the ventilatory rate could worsen hypercapnia if not paired with improved lung mechanics, and it does not address the underlying obstruction. Intubating the patient again may be unnecessary and carries risks if the obstruction can be treated with bronchodilation. Applying PEEP could further complicate ventilation issues in the presence of significant airway obstruction, as it may make it more difficult for the patient to exhale fully. In conclusion, administering albuterol directly targets the issue at hand by addressing bronchospasm, thus is the most effective course
