What is ventilation? inspiration (acquiring oxygen) and expiring (removing co2) Describe the different measures of ventilation. - tidal volume (tv)--volume of air going in and out at rest - vital capacity (vc)--maximal amount of air that can deliberately be moved in or out of lungs with forced inhalation and exhalation - forced vital capacity (fvc)--maximal amount of air that is exhaled from lungs during forced exhalation - forced expiratory volume in 1 second (fev1)--maximal amount of...

What is the difference in chronic and acute ventilators failure? Answer In both cases, CO2 is >45 but with chronic pH is normal. When acute, pH is <7.35 acute alveolar hyperventilation Answer pH normal and CO2 <35 Normal VC (vital capacity) Answer 65-75 mL/Kg (10 x VT) Initial PIP for infants Answer 20-30 or 4-6 mL/Kg VC and VE extubation criteria Answer VC > 10 mL/Kg and VE < 10 What other drugs besides SABA and corticosteroids can be used to tx acute asthma? ...
