Question | Answer |
Lung and Respiratory parameters include what four things? | rate of flow ,lung volume, lung capacity, pressure |
Rate of flow is what ? | movement of air in and out of the lungs |
What is lung volume? | the amount of air that can make it into the lungs at a particular time. measured in cc |
What is lung capacity ? | the combination of volumes that express physiological needs .measured in cc |
What is pressure ? | measurement of the force of expiration measured as a cm of H20 or mmHg |
What are two things that can measure rate of air flow, lung volumes, lung capacities | west spirometer and commercial or computerized spirometer |
What is a wet spirometer ? | a device used to measure the volume of the air expired and inspired by the lung. It consists of two containers one has a tube attached to it and contains water. |
When do the lungs develop ? | In Utero |
At birth the _____ portion of the airway is completely developed ? | the cartilaginous portion |
Volumes and capacities are variables that are controlled by the breathing system. | they are important because they are tools that measure the efficiency of the respiratory apparatus. and help diagnose disorders |
What are the five types of volumes ? | Tidal Volume(TV), inspiratory reserve volume(IRV) expiratory reserve volume(ERV) residual volume (RV) and dead space |
What is Tidal volume ? | Volume of air inspired and expired during normal quiet breathing |
What is Inspiratory Reserve Volume ? | The amount of air that can be maximally inhaled after the inspiratory tidal volume. |
What is Expiratory Reserve Volume ? | The maximum amount of air that can be forcibly exhaled beyond the expiratory tidal volume |
What is Residual volume ? | The amount of air remaining in the lungs after maximum expiration. |
What is anatomic dead space ? | The conducting zone that starts from the nose to the respiratory bronchioles where no gas exchange occurs . It is about 150 cc |
The air in this zone is the last air to be exhaled in a cycle and the first air to enter in the following cycle | The anatomic dead space |
What are lung capacities ? | They are lung volumes that are the sum of two or more lung volumes |
What are the four lung capacities ? | Total lung capacity . Vital lung capacity, the inspiratory capacity , Functional residual capacity |
What is vital capacity | The volume of air that can be exhaled from the lungs after a maximum inspiration. VC= IRV+TV+ERV |
Functional Residual Capacity | The amount of air remaining in the lungs after quiet normal exhalation FRC=ERV+RV |
Inspiratory Capacity | Max amount of air that can be inhaled above tidal volume( inspiratory) IC=IRV+TV |
Total lung capacity | volume of air in the lungs after max inspiration TLC=TV+IRV+ERV+RV we never use total lung capacity because we always have RV |
Atmospheric pressure | the atmosphere exerts a pressure of 760mmHg on the earth it is used as a reference point it is considered zero. |
intraoral pressure | air pressure measured within the oral cavity |
subglottal pressure | pressure measured below the vocal folds |
Alveolar pressure | pressure within the alveolus |
intrapleural pressure ( negative pressure) | pressure between the pleural membranes. |
when Breathing for life, the location of air intake is the ___ | nose |
When breathing for speech the location of air intake is the ____ | mouth/oral cavity. |
