A 12-year-old boy suffers an enlarging neurogenic tumor in the right posterior mediastinum, as shown in the given lateral view radiograph. This growth causes multiple lesions of the right thoracic sympathetic trunk below the T5 chain ganglion. Which of the following functions is most likely compromised?

Strategies to reduce auto-PEEP in mechanically ventilated patients with obstructive lung disease include which of the following?1. Use high inspiratory flows (60 to 100 L/min).2. Apply extrinsic PEEP.3. Use high VT values of 8-10 mL/kg4. Use high respiratory rates (>25/min).

The respiratory therapist review the ventilator flow sheet for a post-op patient. The vent settings have not changed during the past 24 hours. The peak and plateau pressure were recorded as follows: Time:                                            0700am        0900am         1100am Peak Pressure:                                 24                   28                    34 Plateau Pressure:                             20                   24                    30   What is the problem?

A patient is on mechanical ventilation with a tidal volume (VT) of 550 mL, a peak inspiratory pressure (PIP) of 25 cmH₂O, plateau pressure of 20 cmH₂O, a positive end-expiratory pressure (PEEP) of 5 cmH₂O, and a FiO2 of 50%. What is the dynamic compliance of the patient’s lungs?
