The partial pressure of O 2 in the atmosphere where live is about half of the PO 2 at sea level. As a result, the PO 2 in the lungs of llamas is about 50mm Hg, whereas that in human lungs at sea level is about 100mm Hg. Concept introduction: The hemoglobin pigment act as a vehicle for transport of oxygen in blood. The oxygen-hemoglobin dissociative curve is a curve that shows the percentage of saturated hemoglobin on the y- axis and succeeding oxygen tension on the x-axis.

Summary Introduction

To compare:

A dissociation curve for hemoglobin and adaptation to living where air is “thin”. The curve showing the percentage of saturation (the amount of O₂ bound to hemoglobin) at increasing values of P0₂. Partial pressure reflects the relative amount of gas in a mixture and is measured in millimeters of mercury 9mmHg). Llamas are native to the Andes Mountains in South America. The partial pressure of O₂ in the atmosphere where live is about half of the PO₂ at sea level. As a result, the PO₂ in the lungs of llamas is about 50mm Hg, whereas that in human lungs at sea level is about 100mm Hg.

The atmospheric pressure on the top of Mt. Everest, an altitude of 29,035 ft, is only 259.9 mm Hg. What is the partial pressure of oxygen in the lungs at this altitude (assuming that the % O2 is the same as in dry air, 20.88%)? Report the pressure to the tenths of a mm Hg without units.

The arterial O₂ concentration is given by the following expression [0₂] = 0.003 P0₂ + (PO₂)².8 +(26) 2.8 1. ЗЧНЬ (Рог ) 2-8 Where Poz is the alveolar O₂ pressure and Hb is the hemoglobin concentration in g/dL, respectively A subject who is at 0-95 ATM (211-0₂) has an arterial O₂ concentration of 19ml/dL and and arterial CO₂ pressure of 38mm Hg. Also, VO₂ = 340mL/min.; VCD₂ = 289 mL/min. Therefore, your hemoglobine level is: A. 14.39 Idl 8. 14.8 g/dl C. 15.2 g/dl D. 15.7g/dL E. 16 g/dL

Using the regional barometric pressure info. below, and being careful to consider the vapor pressure in saturated alveolar air, calculate the alveolar oxygen pressure (PAO₂) (mmHg) for the following location: .
