➤ How do clinicians calculate energy requirements for hospitalized COPD patients?
Use indirect calorimetry when available for the most accurate resting energy expenditure. Otherwise apply predictive equations (Harris‑Benedict) or weight-based estimates (about 25–30 kcal/kg/day) and multiply by a stress factor of roughly 1.2–1.5 for an exacerbation. Reassess needs regularly and adjust for fever or ventilation status.

➤ How should INR values affect eligibility for intravenous alteplase?
An INR of 1.7 or lower is generally required to proceed with intravenous alteplase. Values above 1.7 indicate increased bleeding risk and are considered a contraindication to standard fibrinolysis. Always confirm INR immediately, repeat if needed, and consult neurology and hematology before making a treatment decision.
