Scenario Overview: You respond to a 30-year-old male patient involved in a high-impact diving accident. The patient is suspected of having a cervical spine injury, presenting with hypotension, bradycardia, and signs of paralysis. His respiratory function is deteriorating, indicating a need for potential advanced airway management. Your task is to assess and manage the patient during the on scene, en route, and post scene phases, making clinical decisions to prevent further complications.Post Scene Phase:Post-intubation, the ICU team notes that the patient has developed decreased lung compliance. What is the likely cause, and what intervention might be necessary?

Scenario Overview: You respond to a call involving a 25-year-old male who was involved in a high-speed motor vehicle collision. The patient was ejected from the vehicle and presents with altered mental status, suspected traumatic brain injury (TBI), and evidence of Cushing’s triad. As you assess the patient, he shows hypertension, bradycardia, and an irregular respiratory pattern. His condition is deteriorating, and he develops signs of brain herniation and abnormal posturing. You will face critical decisions regarding advanced airway management as the patient’s respiratory status worsens.On Scene Phase:As the patient’s respiratory effort becomes more erratic and shallow, what is the next appropriate intervention?
