Respiratory System-A

QuestionAnswer
Resting Tidal Volume The amount of air moved into or out of lungs during a single respiratory cycle
Expiratory Reserve Volume The amount of air you can voluntarily expell after you have completed a normal respiratory cycle
Residual Volume The amount of air that remains in your lungs even after maximum exhalation
Minimal Volume The amount of air which would remain in your lungs even if they were collapsed
Inspiratory Reserve Volume The amount of air you can take into your lungs over and above tidal volume
Inspiritory Capacity Tidal volume plus IRV
Functional Residual Capacity The amount of air remaining in lungs after a quiet respiratory cycle
Vital Capacity Maximum amount of air that you can move into or out of your lungs in a single respiratory cycle
Total lung capacity Total volume of your lungs (Vital capacity plus residual volume)
Anoxia A condition of tissue oxygen starvation (not limitation)
Hypoxia Low tissue oxygen levels
Asthma An acute respiratory disorder characterized by unusually sensitive, irritated conducting airways
Atelectasis A collapsed lung
Bronchitis Inflamation of bronchial lining
cystic fibrosis A lethal inherited disease caused by an abnormal membrane channel protein; mucous secretions become to thick to be transported easily, leading to respiratory problems
Decompresion sickness-alternate name? The Bends
Decompression sickness-definition? A condition caused by a rapid drop in atmospheric pressure and the resulting formation of nitrogen gas bubbles in body fluids, tissues and organs
Emphysema A chronic, progressice condition characterized by shortness of breath and an inability to tolerate physical exertion
Epistaxis Nosebleed
Heimlich maneuver-Alternate name? Abdominal thrust
Heimlich maneuver-definition? Compression applied to the abdomen just inferior to the diaphram, to force air out of the lungs to clear a blocked trachea or larynx
Hypercapnia Increase in the PC02 of arterial blood
Hypocapnea abnormally low PCO2
Lung cancer-alternate name? pleuropulmonary neoplasm
pleuropulmonary neoplasm Lung cancer
Mountain sickness An acute disorder resulting from CNS effects due to the low gas partial pressures that occur at high altitudes
Pleurisy An inflamation of the pleaurae, accomplanied by the secretion of excess amounts of pleural fluid
pneumonia A respiratory disorder characterized by fluid leakage into the alveoli or swelling and constriction of the respiratory bronchioles
pneumothorax the entry of air into the pleural cavity
The pleural cavity the space between the viseral and parietal plerae
Respiratory Distress Syndrome A condition resulting from the production of inadequate surfactant and associated alveolar collapse
SIDS Death of an infant to to respiratory arrest. Unkown cause
tracheostomy insertion of a tube directly into the trachea to bypass a blocked or damaged larynx
tuberculosis-bacteria? Myobacterium tuberculosis
Composition of air-Nitrogen%? 78.6%
Composition of air-O2%? 20.9
Composition of air-other than Nitrogen and oxygen? 0.5%-water, CO2, others
Normal Atmospheric Pressure 760 mm Hg
mm Hg Millimeters of Mercury
Partial pressure The pressure contributed by a single gas in a mixture of gasses
Normal partial pressure of O2 in atmosphere 159 mm Hg
Quiet Breathing AKA? Eupnia
Forced Breathing AKA? Hyperpnea

Anatomic Dead Space Area of lungs that does not permit gas exchange-conducting passageways
Hemoglobin Saturation-Definition? The percentage of heme units containing bound oxygen
The number of heme units per hemoglobin molecule? four
If each hemoglobin is carrying two O2 molecules O2 sat is..? 50%
The most important environmental factors affeting hemoglobin are: PO2 of blood blood pH temperature Metabolic activity withing RBCs
Does venous blood contain oxygen? Yes
Fetal hemoglobin has _______ affinity for oxygen than adult. Greater
Heat has what effect on the release of oxygen? Increases release
BPG ______ the rate of oxygen release Increases
________s generate 3-bisphosphoglycerate RBC
