An asymptomatic patient breathing room air has the following arterial blood gas results: pH 7.49, PaCO₂ 12 mmHg, PaO₂ 145 mmHg. The patient exhibits normal breath sounds and no signs of respiratory distress. Which conclusion is most appropriate?

A patient receiving mechanical ventilation via an endotracheal tube on A/C pressure-control ventilation has settings of PIP 30 cmH₂O, rate 18/min, PEEP 7 cmH₂O, and FiO₂ of 55%. The high-pressure ventilator alarms sound, and the therapist observes a decrease in bilateral breath sounds along with a drop in exhaled tidal volume from 650 mL to 500 mL.
