Pancreatitis → ARDS

Stop and Think

You are caring for a 48-year-old admitted 18 hours ago with severe acute pancreatitis. On admission the patient was on 2 L nasal cannula with an SpO₂ of 96%. Across your shift you have increased the oxygen twice. The patient is now on high-flow at 50% FiO₂, the SpO₂ is 89%, the respiratory rate is 32, and the patient is restless with new bilateral crackles.

The oxygen requirement keeps climbing and the SpO₂ keeps falling. What is this trend telling you?

Your Turn

Given the history and this trend, which action is the priority?

• A Increase the FiO₂ further and recheck the SpO₂ in one hour. The number improves briefly, but this treats the reading and delays care while the patient deteriorates.
• B Notify the provider about the worsening oxygenation trend and rising work of breathing. Correct. You recognized the trend and escalated before profound respiratory failure.
• C Reassure the patient that the restlessness is expected with pancreatitis pain. Restlessness here is an early cue of hypoxemia, not simply pain. Attributing it to pain misses the trajectory.
• D Document the new crackles and reassess at the next scheduled vital signs. Waiting on a scheduled reassessment delays action on a patient who is actively worsening.

Why B

The diagnosis you were handed is pancreatitis. The complication you are anticipating is ARDS. Severe acute pancreatitis can trigger systemic inflammation that injures the alveolar-capillary membrane, an indirect cause of acute lung injury. You are not diagnosing ARDS. You are reading the trajectory and acting on it.

• Recognize cues: Rising oxygen requirement, falling SpO₂, RR 32, restlessness, new bilateral crackles.
• Analyze cues: Oxygenation is worsening despite more oxygen. In a patient with severe pancreatitis, developing acute lung injury fits.
• Prioritize hypothesis: Worsening oxygenation / developing ARDS, not pain and not a stable finding to chart later.
• Take action: Support oxygenation, increase surveillance, and escalate early. Notifying the provider on the trend is the priority.
