Mаrgаret Chen, а 78-year-оld female, presents tо the ED with a 4-day histоry of productive cough, fever (101.8°F), dyspnea, and fatigue. Past medical history includes hypertension and a 40-pack-year smoking history (quit 10 years ago). Vital signs: HR 102, RR 28, BP 148/86, temp 101.8F, SpO₂ 88% on room air Ms. Chen is admitted for community-acquired pneumonia. Sputum and blood cultures were obtained before starting broad-spectrum antibiotics. Oxygen therapy initiated via nasal cannula at 4 L/min, maintaining SpO₂ 92%. Hydration and nutrition support begun. Early mobility encouraged within tolerance. She has a DNR and DNI. Deterioration - Day 2:Despite antibiotic therapy, Margaret's respiratory status worsens. Oxygen requirements increase to high-flow nasal cannula at 6 L/min. Bilateral infiltrates now visible on chest X-ray. ABG shows worsening hypoxemia (PaO₂ 58 mmHg on high-flow oxygen). At shift change, Margaret develops severe respiratory distress. She becomes increasingly hypoxemic despite oxygen at 15L via NRB. BiPAP is applied and Margaret initially improves. However, during the night her condition worsens and the nurse increases the pressure on the BiPAP to 15cm. At this point, this is causing her blood pressure to drop. Margaret has one word dyspnea and a respiratory rate of 32. The nurse gets the hospitalist to discuss intubation. What should the next step be?
