Consolidation correct answer: Atelectasis, pleural thickening and consolidation. In patients with chronically high PaCO2 and low PaO2 what is the primary receptor site for the control of ventilation? correct answer: Central chemoreceptors Tachypnea may be the result of: 1. hypoxemia. 2. hypothermia. 3. fever. 4...

A patient receiving mechanical ventilation has an exhaled tidal volume (VT) of 500 mL and a positive end expiratory pressure setting (PEEP) of 5 cm H2O. The respiratory therapist should recommend which of the following for this patient? (picture) 1. Tracheobronchial suctioning 2. Increase in the set tidal volume 3. Beta adrenergic bronchodilator therapy 4. Increase positive end expiratory pressure correct answer: 1 and 3 only The values below pertain to a patient who is being mechanica...

Normal FEV1 correct answer: 83% What shape of the flow-volume loop is typical for the patient with a fixed upper airway obstruction? correct answer: Box Which of the following volumes or capacities cannot be measured by simple spirometry? correct answer: FRC & RV A subject who complains of SOB has an FVC of 2.57, but her VC is 2.99L. These findings suggest which of the following.. correct answer: Emphysema The main indication for the measurement of lung volumes is to do which of ...

By strict definition, what is "high frequency ventilation"? correct answer: Rates greater than or equal to 150 What is MAP? correct answer: Mean Airway Pressure = the mean pressure delivered during positive pressure ventilation What adjustment should you make on the oscilator to reduce PaCO2 (increase Vt)? correct answer: You could adjust the power setting to increase the amplitude. By doing this, it increases Delta P which would result in an increase in Vt. This is the primary way to...
