Miss Bowling is being mechanically ventilated. Her expired minute ventilation is excessively large. What affect will it have on arterial carbon dioxide tension (PaCO2)?

Calculate Lucy Lui’s dead space ventilation using the following information: Respiratory rate = 20 breaths per minute Exhaled tidal volume = 500 mL Predicted body weight = 100 pounds Actual body weight = 200 pounds

A patient in the assist/control mode of ventilation has 5 cm H20 of auto-PEEP. The sensitivity is set on – 2 cm H20. In order to trigger a breath, the patient must generate a pressure of _________ cm H20.

Which of the following is an indication for oxygen therapy?

Identify the mode of ventilation.

During an optimal PEEP study, a mechanically ventilated patient’s PEEP was increased to 8 cm H20 with no obvious adverse reactions. Thirty minutes later, the PEEP was increased to 12 cm H20. Immediately thereafter, his heart rate increased by 24 beats/minute. His blood pressure decreased from 116/90 mm Hg to 108/74 mm Hg. What should be recommended?

A patient’s spontaneous exhaled minute ventilation is 10 liters per minute. His exhaled tidal volume is 450 mL. What is his calculated respiratory rate?

A respiratory therapist intubated a 60-year-old male patient and connected to a mechanical ventilator. Previously, he was on non-invasive ventilation with the following settings: IPAP: 15 cm H20 EPAP: 8 cm H20 35% oxygen What should be the initial FiO2?  

A 47-year-old man with chronic kidney disease comes to the clinic for a 3-month follow up appointment. At his last visit, his eGFR was 32mL/min/1.73m2.  Today his eGFR is 50 mL/min/1.73m2.  What is the classification of his chronic kidney disease at this visit?
