The partial pressure of oxygen in the lung alveoli is a bit lower than in ambient air, being about 100 mm of mercury, or 0.13 Atm (it is lower than the partial pressure in air mainly because oxygen is continually taken up by the alveolar capillaries and carbon dioxide is continually released into the alveoli). In cell-free blood plasma (or a saline solution formulated to match key characteristics of blood plasma), which lacks red blood cells and therefore lacks hemoglobin,...

During transport to the hospital, vital signs were reassessed: HR 138, BP 75/50, RR 38 with confusion. She was diagnosed with hypovolemic shock and IV fluids were doubled. Blood samples were sent for typing and cross-matching and for both chemical and hematologic analysis.

Blood pressure is a measure of the blood force against the walls of the arteries. Blood pressure that is consistently more than 140/90 mm Hg is considered high, but for people with diabetes, 130/80 mm Hg is considered high. Normal blood pressure is below 120/80 mm Hg. The larger value represents the pressure when the heart contracts and pushes blood out (systolic), and the smaller value is the lowest pressure when the heart relaxes between beats (diastolic). Consider a population...

MODEL 3: PARTIAL PRESSURE Dry air is 78% nitrogen, 21% oxygen, and 1% argon. A percentage is a ratio: "78%" means that out of 100 particles 78 will be nitrogen, or 0.78 as a fraction. Such fractions are unitless. CRITICAL THINKING QUESTIONS 15. Approximately what is the pressure in the room where you are working? (Include the units.) 16. What three gases are causing this total pressure? 17. What fraction (not percent) of air molecules are nitrogen molecules? Oxygen molecules?...
