<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 71-year-old man is admitted to the hospital one hour after he was found unconscious. His pulse is 80min and systolic blood pressure is 98 mm Hg; diastolic blood pressure cannot be measured. He is intubated and mechanically ventilated with supplemental oxygen at a tidal volume of 450 mL and a respiratory rate of 10min. Arterial blood gas analysis shows:PCO2 43 mm HgO2 saturation 94O2 content 169 mLLPulmonary artery catheterization shows a pulmonary artery pressure of 15 mm Hg and a pulmonary capillary wedge pressure of 7 mm Hg. Bedside indirect calorimetry shows a rate of O2 tissue consumption of 325 mLmin. Given this information, which of the following additional values is sufficient to calculate the cardiac output in this patient?? A: End-tidal carbon dioxide pressure, B: Total peripheral resistance, C: Partial pressure of inspired oxygen, D: Left ventricular end-diastolic volume, E: Pulmonary artery oxygen content,  <response>: This is a question about calculating cardiac output. To calculate cardiac output, we need to know oxygen consumption and the arteriovenous oxygen content difference. We are given the oxygen consumption of 325 mLmin. To get the arteriovenous oxygen content difference, we need the arterial oxygen content which we are given as 169 mLL and the mixed venous oxygen content. The mixed venous oxygen content can be calculated from the pulmonary artery oxygen content. Therefore, the pulmonary artery oxygen content is the additional value needed to calculate cardiac output.E: Pulmonary artery oxygen content
