Calculate the rapid shallow breathing index (RSBI) using the following values.            Peak Flow:  40 Lpm                  FiO2:   0.50                  Tidal volume:  300 mL              Respiratory Rate:  18 bpm         SpO2: 89%

Which of the following will cause work of breathing (WOB) to increase?

The total rate of a mechanically ventilated patient is 10 bpm. At this rate, the ABG reveals a PaCO2 of 60 torr. Assuming the Vt remains constant, calculate the respiratory rate necessary to achieve a PaCO2 of 40 torr.

A therapist wishes to examine the following in a patient post stroke: a) strength of the hip abductors in standing, b) reactive postural responses, c) proprioception in standing, and d) walking with head turns.  The BEST outcome measure to administer is the:

Which of the following values indicates a need for mechanical ventilation?

Which of the ABGs is consistent with “acute ventilatory failure”?

After intubation and initiation of mechanical ventilation at the NBRC hospital, the physician asks you to provide an appropriate tidal volume for a female patient with an IBW of 55 kg. You would recommend a tidal volume of

A patient with MS exhibits moderate fatigue during a 30-minute exercise session. When the patient returns for her next visit 2 days later, she reports going to bed right away due to exhaustion and reported difficulty getting out of bed until late afternoon of the next day.  The PT’s best strategy is to:

Which of the following are the most appropriate initial ventilator settings for a 47 yo male with idiopathic pulmonary fibrosis? (IBW 62 Kg)?

A patient presents with difficulty with fast movement speeds and fatigues easily.  The therapist decides on a strength training program that specifically focuses on improving fast-twitch fiber function.  The optimal exercise prescription to achieve this goal is:
