A 55-year-old male presents with GI bleeding.   Arterial blood gas results reveal an arterial oxygen tension of 45 torr.  Pulse oximetry readings are unreliable.  The patient is in mild respiratory distress, but is not cyanotic. To evaluate the patient’s oxygenation status further, it is most important to review the patient’s

A 65-year-old patient who is post-CABG was extubated 4 hours ago and complains of increasing shortness of breath.  Breath sounds are decreased over the right lung field. The following data are available:HR 105RR 25BP155/90 mm HgSpO290% on 4-L nasal cannulaWhich of the following studies should a respiratory therapist recommend NEXT?

When administering dornase alfa (Pulmozyme) with a hand-held nebulizer, a respiratory therapist notes a patient is developing marked congestion with copious sputum production.  The therapist’s most appropriate action is to pause the treatment and

Following insertion of a CVP catheter, a chest radiograph is taken to evaluate the position of the catheter.  When viewing the radiograph, a respiratory therapist notes the tip of the catheter is in the superior vena cava.  The therapist should conclude the catheter

A 34-week gestational age infant has been stable while receiving mechanical ventilation.  Oxygen saturation decreases to 85% and does not respond to an increased FIO2. Transillumination of the chest produces a 1-cm halo that extends around the point of contact with the skin.  Which of the following should a respiratory therapist recommend?

A 77-year-old male patient is scheduled to undergo open heart surgery.  Preoperative spirometry results show the patient’s FEV1 is 80% of predicted and the FEV1/FVC is 83%, indicating

A patient has a reported SaO2 of 90%, hemoglobin 15, PaO2 of 61 mmHg, cardiac output of 6 L/min, and CvO2 of 14.2 vol%. What would the C(a-v)O2 equal?
