A patient receiving PC-CMV has initial arterial blood gas (ABG) findings as follows: PaO2 of 101 mm Hg, partial pressure of carbon dioxide in the arteries (PaCO2) of 60 mm Hg, and pH of 7.30. The respiratory therapist should:

Calculate the static compliance (Cs) given the following data: PIP 25 cm H20 PPLAT 10 cm H20 PEEP 5 cm H20 Vt Inhaled 515 Vt Exhaled 500

Sustained hyperventilation of up to _____hours may result in respiratoryalkalosis. This condition reduces cerebralblood flow and intracranial pressure(ICP) and may be beneficial to patientssuffering from ______ .

Which of the following conditions could lead to decreased lung compliance? 1. ARDS 2. Pulmonary Fibrosis 3. Pulmonary Edema 4. Pneumonia  

Which of the following would be most likely to increase GFR?  

Substance X is a mostly polar molecule and substance Y is a mostly non-polar molecule of a similar size. Which will diffuse from the extracellular fluid to the intracellular fluid faster if they are in equal concentrations outside and inside the cell?

You have a science club outreach to the kindergarten to explain respiration. You made a spirometer with a tub of water, tube, and jug filled with water. You fill the jug with water and invert it into the tub and connect the tube. You ask each child to breath normally for five breaths, then, after a normal inhalation, have them exhale normally into the tube to displace water from the jug. You have the child repeat this five times. Upon completion, you recover the jug and measure how much water has been displaced and divide by 5. At the end of the class, you ask all the students of their number and present a class average. What is it that you measured?

Dehydration increases the plasma concentration of all the following hormones except

A Gatech BME student was able to model the movement of O2 from the alveoli into the blood in the pulmonary capillaries. The system consists with two O2 tight containers with O2 permeable membrane in between. O2 can only pass between the two containers but cannot leave the containers. When O2 is injected into one container, she noticed a very fast equilibrium of O2 between the two sides. Which of the following explains the movement of O2 across the membrane in the system and across the alveolar capillary membrane?

A baby born prematurely is taken to the intensive care unit. The baby is quickly intubated through the nose to the airways and is given surfactant with noninvasive positive pressure ventilation. Surfactant replacement and aided breathing continue until the baby can breathe on its own. The purpose of the surfactant treatment is to:
