- A patient receiving control-mode continuous mandatory ventilation has the following ABGs on an FiO2 of 0.4: pH = 7.51; PCO2 = 30 mm Hg; HCO3– = 25 mm Hg. Her current minute ventilation (VE) is 7.9 L/min. What new VE would you recommend? 9.0 L/min 6.7 L/min 7.5 L/min 5.9 L/minarrow_forwardAs a result of the excessive blood loss, the patient's Pa(o2) of 503 mm Hg and Sa(o2) of 98 percent were very misleading. Which oxygen transport studies verified this fact? _______________________________________________arrow_forwardTrue or False and why. "If a person exhibits alveolar partial pressure for oxygen equivalent to that of the humidified inspired air, then this could mean that alveolar ventilation and capillary blood flow are above normal rates".arrow_forward
- How many moles of air are in the lungs of an average person with a total lung capacity of 3.8 L? Assume that the person is at 1.0 atm pressure and has a normal body temperature of 37 °C.arrow_forwardTo determine the possible obstruction of the airway, a FEV may be measured using a spirometer. Under normal circumstances, a healthy adult can expel 75% to 85% of the vital capacity in 1.0 second (FEV1). Predict how this would change in a person who has asthma and explain the reason why.arrow_forwardUnder certain circumstances, the respiratory quotient (RQ value ) for an athlete exercising intensely can rise above one. How is this possible?arrow_forward
- Under certain circumstances, the respiratory quotient (RQ value) for an athlete exercising intensely can rise above 1. How is this possible?arrow_forwardAs CO2 increases in arterial blood, CO2 will combine with H2O and form H2CO3 in the cerebral spinal fluid. H2CO3 will break down to H+ and HCO3- and the H+ stimulate the medulla to increase the rate and depth of breathing True Falsearrow_forwardThe diaphragm of an individual no longer functions normally due to an accident.
