1.12 At elevated altitudes, the body adapts to thereduced barometric pressure to extract sufficient oxy-gen to permit normal metabolic functions and do work.For example, at an altitude of 3,650 m (close to 12,000feet above sea level) the barometric pressure drops to485 mmHg. For an oxygen pressure drop in the lungsof 30 mmHg, determine the oxygen uptake rate for arespiration rate of 20 breaths per minute. Estimate theoxygen saturation in venous blood if the hematocritrises to 0.60 and the partial pressure of oxygen blood isat a partial pressure equal to 98% of the alveolar level.

In healthcare, precision and accuracy in calculations hold immense significance, especially when…

Which one of the three variables: Pressure, Volume or Temperature cannot be changed in Charles' Law? This varlable is considered a constant. 1. a. Using the Temperature controls, increase the temperature of the gas. What changes do you observe in the behavlor of the particles of the gas while the temperature is increased? b. Continue to increase the temperature value until T, = 44K. Using the equation for Charles' law, calculate the volume of the gas at this increased temperature. Check your final answer for part b by clicking the calculate button next to V2: c. Based on the final value calculated in part b) is Charles' law considered a direct or an indirect relationship between the variables? Explain your cholce with reasoning. 1. 2.

51 Messner and Habeler's 1978 ascent of Mount Everest without oxygen-breathing apparatus is often described as one of the most remarkable physical accomplishments achieved by humans. Table 1 shows respiratory gas and arterial pH values measured in a resting mountaineer at sea level, Everest base camp and Everest summit. Use the differences in these values to explain how breathing regulation changes when at rest at the 3 altitudes indicated. Calculations are not required but you may wish to consider the role of central and peripheral chemoreceptors and their relationship to paco,, minute ventilation and alveolar pO, in your response.

Mechanical ventilation is indicated when the patient's spontaneous ventilation is inadequate to sustain life by hooking the patient into a mechanical ventilator. It provides breathing support until lung function is restored, delivering warm (body temperature 37° C [98.6° F]), 100% humidified oxygen at FiO2 levels between 21% to 100%. 1. Discuss the process how does positive-pressure ventilator deliver air to the lungs? List 3 risks or complications of patient who is hooked in mechanical ventilator and discuss how it is even possible.
