While breathing spontaneously, a 54.5-kg (120-lb) female has a respiratory rate of 30 and a tidal volume of 200 mL.  After a sedative was administered, her respiratory rate decreased to 10 and her tidal volume increased to 600 mL.  Which of the following ventilatory parameters increased?

While reviewing a medical record, a respiratory therapist notes a patient has shortness of breath, pleuritic chest pain, low-grade fever, tachypnea, tachycardia, and a swollen and tender right leg.  The patient has a 50 pack-year history of smoking and known coronary artery disease.  These findings are MOST consistent with
