Mr. Brookshire is undergoing a multi-stage progressive cardiac stress test in the cardiopulmonary departments diagnostic lab, his maximum HR has been set at 250 bpm, the ECG monitor shows a NSR and he has a SpO2 of 96% on RA. He has been progressed in the stage of the testing and his HR on the monitor now shows HR 210, he states he has audible wheezing, beginning to sweat profusely, the ECG monitor is showing some abnormalities and the SpO2 is 87% on RA. What are your recommendations at this time?

Which port should be utilized to attain a sample for a mixed venous (SvO2) reading on a PA Catheter?

A patient is brought in from a local construction site by ambulance after falling off scaffolding onto concrete steps. At the scene the man was complaining of severe chest pain and stated “I can’t get my breath.” When he arrives at the emergency department he only responds to painful stimulation, is breathing shallowly 16 bpm and has a SpO2 reading of 82% on a 100% NRB mask. On visual examination you note profound paradoxical movement of his left anterior chest wall. The physician orders STAT ABGs. Which of the following results would you expect with this patient?

A 19 year old man is brought to the ED after experiencing sharp chest pain while playing basketball. Upon observation of the young man, reveals a tall, thin man in severe distress. Despite being placed on a 10 L/min SM, the patient shows peripheral and central cyanosis. Percussion of the right side yields a dull percussion note and on the left it is noted to have a hyperresonant note. Additionally, a distinct shift in the trachea toward the right side is noted. Cardiac leads are attached and the ECG monitor shows sinus tachycardia with frequent multifocal PVCs. The B/P can only be palpated at 50 mmHg systolic, diaphoresis and cyanosis. Which of the following should the RT recommend?

What is considered the afterload of the right ventricle?
