A 68-year-old patient arrives in the emergency department with an acute exacerbation of COPD. Assessment findings include:Severe dyspneaRespiratory rate: 34 breaths/minSpO: 84% on a non-rebreather maskABG: pH 7.28, PaCO 68 mmHg, PaO 55 mmHgIncreased work of breathing and accessory muscle useAlert and able to follow commandsThe healthcare team is considering whether to initiate noninvasive ventilation (NIV) or invasive mechanical ventilation. Would you recommend NIV or invasive mechanical ventilation initially? Why?Support your decision using indications, contraindications, advantages, and risks discussed in the chapter. What ventilator mode would you choose and why?Discuss the benefits and limitations of your selected mode (e.g., VC-CMV, PC-CMV, SIMV, PSV). Identify at least three initial ventilator settings you would recommend and explain your rationale.Examples may include tidal volume, respiratory rate, FiO, pressure support, PEEP, or trigger settings. What complications or patient-ventilator issues would you monitor for after initiation of support?Consider factors such as VAP, VALI, barotrauma, auto-PEEP, or patient-ventilator asynchrony.
