A TBI patient has a BP of 110/60 (MAP 77) and an ICP of 22 mmHg. Calculate the CPP and determine if it meets the target range for a 35-year-old male according to current guidelines.
Show answer →CPP = MAP - ICP. 77 - 22 = 55 mmHg. This is BELOW the standard adult target of 60-70 mmHg. In the flight environment, maintaining CPP >60 is critical to prevent secondary ischemic injury. Strategy: BCEN often tests the calculation first, then asks for the intervention (e.g., fluid bolus or vasopressors to increase MAP). Avoid targets >70 mmHg as they increase the risk of ARDS due to aggressive fluid/pressor use.
A trauma patient with a pelvic fracture and SBP 85 mmHg is 2 hours post-injury. You are initiating MTP. According to 2026 standards, what is the critical window for Tranexamic Acid (TXA) administration and the standard dosing?
Show answer →TXA must be administered within 3 hours of injury. Administration after 3 hours is associated with increased mortality due to potential pro-thrombotic shifts or fibrinolysis changes. Standard dosing: 1g IV bolus over 10 minutes, followed by 1g over 8 hours (or a 2g slow IV push per newer prehospital protocols). BCEN Exam Tip: BCEN emphasizes the 3-hour rule. If the scenario states the injury occurred >3 hours ago, TXA is generally withheld. TXA works by inhibiting plasminogen activation, which stabilizes existing clots.
An intubated asthma patient has a PIP of 55 cmH2O and a Pplat of 24 cmH2O. What is the most likely cause of this pressure gradient and the immediate ventilator goal?
Show answer →The large gradient between Peak Inspiratory Pressure (PIP) and Plateau Pressure (Pplat) indicates high airway resistance, classic in obstructive disease (asthma/COPD). The goal is to maximize expiratory time to prevent dynamic hyperinflation (auto-PEEP). \n\nExam Strategy: BCEN often tests the difference between PIP (resistance) and Pplat (compliance). In obstruction, PIP is high but Pplat remains low unless air trapping occurs. Target Pplat <30 cmH2O to prevent barotrauma. Manage with high inspiratory flow rates (80-100 L/min) to shorten Ti and lengthen Te.
A 75kg septic patient remains hypotensive after 1L of LR. Per current guidelines, what is the appropriate initial weight-based crystalloid volume, and what is the preferred fluid type?
Show answer →30 mL/kg (approx 2,250 mL). Balanced crystalloids (LR/Plasma-Lyte) are preferred over 0.9% NS to reduce risk of hyperchloremic metabolic acidosis and AKI. BCEN Tip: 30 mL/kg is a strong recommendation for initial resuscitation, but monitor for fluid overload in transport, especially in CHF/ESRD.
A term neonate is born in a flight hangar. After initial drying and stimulation, the infant remains apneic with a heart rate of 82 bpm. What is the immediate priority according to the 2026 NRP algorithm?
Show answer →Initiate Positive Pressure Ventilation (PPV) immediately. Indications for PPV include apnea, gasping, or a heart rate < 100 bpm. \n\nClinical Pearl: The Golden Minute emphasizes that PPV should be started within 60 seconds of birth if the infant is not responding to initial steps. For term infants, start PPV with 21% O2 (room air). For preterm infants (<35 weeks), start with 21-30% O2. Use a flow rate of 10 L/min and a PIP of 20-25 cm H2O. \n\nExam Strategy: BCEN often tests the HR threshold for PPV. Remember: <100 = PPV; <60 = Chest Compressions (after 30s of effective PPV).
