Ilike Running is training for a marathon. While training, his volume of air in each breath is 1.5 L and he takes approximately 15 breaths per minute. His total lung capacity is 5500 mL and his residual volume is 1500 mL. Ilike has a blood pH of 7.2 and his cardiac output is 4.95 L/min. His heart is pumping 172 times per minutes. Finally, his expiratory reserve volume is 750 mL. In order to increase his performance, Ilike wants an analysis of his current exercise values. Please determine the following based on the information listed above. Answe the following Blank 1: Tidal Volume Blank 2: Vital Capacity Blank 3: Ventilation Blank 4: Stroke Volume Blank 5: Inspiratory Reserve Volume:
Suppose a person has a total lung capacity of 5,800 mL,a residual volume of 1,200 mL, an inspiratory reservevolume of 2,400 mL, and an expiratory reserve volume of1,400 mL. Calculate his tidal volume.
What would be the expired minute volume (VE) of someone who takes 2.5 breaths every 30 seconds and has a tidal volume (VT) of 0.2L? Show your work.
A spontaneously breathing patient has a normal PaCO2 of 40 mm Hg, a minute ventilation (VE) of 6 L/min, and a VD/VT ratio of 35% (0.35). Then the patient develops a pulmonary embolus (PE), blocking blood flow to a significant number of ventilated avleoli. Consequently, the measured VD/VT increases to 65% (0.65). 1. Calculate the alveolar ventilation associated with teh original PaCO2 of 40 mm Hg. 2. To maintain the same PaCO2 of 40 after the embolus occurs, what change must occur in total minute ventilation (VE)?
What are the normal values for males and females for the following: inspiratory reserve volume expiratory reserve volume residual volume inspiratory capacity functional residual capacity vital capacity total lung capacity?
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/min
Using the data from the table below, calculate Total Lung Capacity and Total Pulmonary Ventilation. Include the correct units. Tidal Volume 0.5 L Inspiratory Reserve Volume 3.0 L Expiratory Reserve Volume 1.1 L Residual Volume 1.2 L Ventilation Rate 13 breaths/min
The total amount of oxygen per hour passing through the Respiratory membrane is equivalent to the total amount of oxygen per hour used by the body. Find the amount of oxygen in cm2 Oxygen/min.
Prior to begin training for a marathon, you have some lung function tests performed. Your measured tidal volume at rest is 550 mL, your dead space volume is 150 mL, and your resting breathing rate is 12 breaths per minute. On a treadmill, your tidal volume increases to 1150 mL and your breathing rate increases to 30 breaths per minute. What is your alveolar ventilation rate when you are on the treadmill? O 30 Liters/min O 4.8 Liters/min O 12 Liters/min O 34.5 Liters/min O 6.6 Liters/min
