A patient on mechanical ventilation is in the supine position for a dressing change. To minimize VAP risk, what is the minimum recommended elevation for the head of the bed (HOB), and what is the primary rationale?
Show answer →The HOB should be maintained at 30-45 degrees. Rationale: This position uses gravity to prevent the aspiration of gastric contents and oropharyngeal secretions into the lower airway. NBRC Tip: If a patient must be flat for a procedure, return them to the semi-Fowler's position immediately after. Supine positioning is a major independent risk factor for VAP.
A patient presents with an exacerbation of COPD and a GCS of 14. Is NIV appropriate? What is the general GCS threshold for NIV?
Show answer →NIV is appropriate for GCS 14. However, a GCS < 10 is generally a contraindication for NIV (except in specific cases of CO2 narcosis where NIV might be trialed under close supervision). Patients must be able to follow commands, cooperate with the interface, and protect their airway. NBRC Focus: Assessment of neurological status and patient cooperation is a critical prerequisite for NIV success.
A patient on FiO2 0.60 and PEEP 5 cmH2O has a PaO2 of 55 mmHg. According to NBRC guidelines, what is the most appropriate next step to improve oxygenation?
Show answer →The patient has refractory hypoxemia (PaO2 < 60 on FiO2 0.60). Increase PEEP to 8-10 cmH2O. NBRC Strategy: Once FiO2 reaches 0.60, further increases in FiO2 are less effective and risk oxygen toxicity. Increasing PEEP improves recruitment and Functional Residual Capacity (FRC). Rule of thumb: Increase FiO2 to 0.60 first, then increase PEEP to achieve target PaO2.
A patient with COPD is being weaned on SIMV with PS. ABG: pH 7.36, PaCO2 58 mmHg, PaO2 65 mmHg, HCO3- 33. What is the correct interpretation and management?
Show answer →This is Compensated Respiratory Acidosis (Chronic Ventilatory Failure), typical for COPD retainers. The pH is within normal range (7.35-7.45). Management: DO NOT increase ventilation. Normalizing PaCO2 (to 40) would cause iatrogenic metabolic alkalosis, leading to depressed drive to breathe and weaning failure. NBRC Pearl: Fix the pH, not the PaCO2 in chronic patients.
A patient in VC-CMV with a set Vt of 450 mL triggers two consecutive breaths with no expiratory time between them. Delivered volume is 900 mL. What is the cause and management?
Show answer →Double triggering (breath stacking) occurs when the patient’s neural inspiratory time exceeds the ventilator''s set inspiratory time (Ti). The patient is still inhaling when the vent cycles to exhalation, re-triggering a second breath. Management: Increase the set Ti or Vt (if safe), or switch to PSV with an adjusted flow-cycle. NBRC Tip: This increases barotrauma risk due to volume stacking.
