To determine: The total pulmonary ventilation for Person L who has a tidal volume of 400 mL and resting ventilation rate of 12 breaths per minute.
Introduction: The total pulmonary ventilation is the volume of air moved in and out of the lungs each minute.
To determine: The total pulmonary ventilation for Person L whose mL ventilation rate of 18 breaths per minute due to nervousness.
Introduction: The bulk exchange of air between the atmosphere and the alveoli of the lungs is described as ventilation. The normal ventilation rate for an adult is 12-20 breaths per minute.
To determine: The alveolar ventilation for Person L in case of resting ventilation rate of 12 breaths per minute and ventilation rate of 18 breaths per minute.
Introduction: Alveolar ventilation is the volume of fresh air that reaches the alveoli each minute.

- The average compliance of the lungs and chest wall combined is 0.1 L/cm H2O. 0.2 L/cm H2O 0.3 L/cm H2O 0.4 L/cm H2Oarrow_forwardThe total lung capacity is calculated using which of the following formulas? residual volume + tidal volume + inspiratory reserve volume residual volume + expiratory reserve volume + inspiratory reserve volume expiratory reserve volume + tidal volume + inspiratory reserve volume residual volume + expiratory reserve volume + tidal volume + inspiratory reserve volumearrow_forwardGiven the following values: ERV=1700mL ERV + TAV= 2200 mL VC= 3000 mL 1) TAV ( TV)= tidal volume= 500ml IRV (inspiratory reserve volume)= 800ml 2) If they have a breathing rate of 14 breaths/min, what is their minute ventilation? 3) If they have the normal dead space ventilation of 150 mL, what is their alveolar ventilation? (show dead space volume as part of the calculation). 4) If they start exercising and increase their breath volume to 1600 mL with 25 breaths per minute, what is their alveolar ventilation now?arrow_forward
- Given the following values: ERV=1700mL ERV+TAV= 2200 mL VC= 3000 mL 1) Calculate TAV and IRV. 2) If they have a breathing rate of 14 breaths/min, what is their minute ventilation? 3) If they have the normal dead space ventilation of 150 mL, what is their alveolar ventilation? (show dead space volume as part of the calculation). 4) If they start exercising and increase their breath volume to 1600 mL with 25 breaths per minute, what is their alveolar ventilation now?arrow_forwardPulmonary ventilation (VE) is determined by two variables. What are they and what do they represent?arrow_forwardWhat is the alveolar ventilation of a resting person with a tidal volume of 500 mL, a dead space of 150 mL, and a respiratory rate of 12 breaths per minute? Suppose the person exercises, so that tidal volume increases to 4000 mL, dead space increases to 300 mL due to dilation of the respiratory passageways, and respiratory rate increases to 24 breaths per minute. What is the alveolar ventilation then? How is the change in alveolar ventilation beneficial for doing exercise?arrow_forward
- If a patient weighs 175 pounds and has a tidal volume of 550 mL and a respiratory rate of 17 breaths/min, what is the patient’s minute alveolar ventilation?arrow_forwardCallisto is hiding from Xena under a pile of leaves. She is worried that if she takes slow, deep breaths (tidal volume = 650 mL, breathing rate = 11/min), the pile of leaves will move up and down, and Xena will notice her. Therefore, she takes rapid, shallow breaths (tidal volume = 210 mL, breathing rate = 25/min). Please note anatomical dead space = 150mL Determine Xena’s alveolar ventilation in both cases and discuss which breathing pattern provides better oxygen supply to her body. Show your calculations.arrow_forwardA person who has a tidal volume of 450 ml/breath, a respiratory rate of 13 breaths/min and an anatomic dead space volume of 130 ml will have an alveolar ventilation rate of: 5850 ml/min O 5730 ml/min O4160 ml/min 5970 ml/min 7540 ml/minarrow_forward
- if patient Y has respiratory rate if 14 breaths per minute, tidal volume of 500 ml and alveolar ventilation of 4,400 ml/min. What is the anatomic dead space volume?arrow_forwardUsing 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/minarrow_forwardMatch the following volumes and capacities with their descriptions. Tidal Volume (TV) Inspiratory Reserve Volume (IRV) Expiratory Reserve Volume (ERV) Residual Volume (RV) Functional Residual Capacity (FRC) Vital Capacity (VC) Total Lung Capacity (TLC) Forced Expiratory Volume (FEV1) Alveolar Ventilation Rate (AVR) Anatomical Dead Space (ADS) _____TV + ERV + IRV + RV _____RV + ERV; the volume of air that remains in the lungs during normal breathing _____The amount of air that enters and leaves the lungs during normal breathing _____The amount of air in addition to tidal volume that enters the lungs during a forced inspiration _____The frequency of breathing x (TV – Anatomical Dead Space) _____The amount of air in addition to tidal volume that is evacuated during forced expiration _____The amount of air forced out in the first second following a maximal inspiration. _____TV + ERV + IRV; represents the maximum volume of air that the lungs can exchange _____The amount of air that…arrow_forward
