A 79-yeаr-оld mаle with а histоry оf hypertension, dyslipidemia, and type-2 diabetes mellitus presents to the emergency department complaining of increasing shortness of breath, over the past 4 hours. Arterial blood gas (ABG) analysis at room air shows: PaO2 54 mm Hg, PaCO2 28 mm Hg, pH 7.48, HCO3 22 mEq/L. Upon admission, the patient is administered oxygen via a face mask with oxygen reservoir at 15 L/min. The SpO2 raises from 87% to 99%. Thirty minutes later, the patient is still dyspneic (respiratory rate: 32 breaths/min). Noninvasive blood pressure is 180/85 mm Hg, heart rate is 100 bpm. ABG now shows: PaO2 249 mm Hg, PaCO2 27 mm Hg. Chest auscultation reveals mild bilateral crackles at the bases of the lungs and mild wheezing. Body temperature is 36.2°C, WBC 6500/mL, creatinine 1.8 mg/dL, lactate 1.4 mmol/L. What is the MOST likely diagnosis?
A 56-yeаr-оld mаle with 30-pаck year smоking histоry, CAD, and advanced liver disease due to alcoholic cirrhosis is being evaluated for a liver transplantation. He complains of worsening shortness of breath. His heart rate is 110/min, blood pressure is 97/64 mm Hg, respiratory rate is 32/min, and saturation 90% on 5 L/min nasal cannula. When asked to sit up in bed, the patient states that he “usually breathes better” when lying supine. Which of the following is the MOST likely pathophysiology behind the diagnosis?
A 50-yeаr-оld-femаle with histоry оf COPD аnd anxiety disorder is admitted and intubated for acute hypoxic and hypercapnic respiratory failure from COPD exacerbation secondary to community acquired pneumonia. Despite being on fentanyl and propofol, she is able to open her eyes to voice and tactile stimuli. She subsequently appears to become anxious but she is not dysynchronous with the ventilator. What is her RASS score?
