Alveolar air volume Correct ans - amount of air that reaches alveoli for gas exchange (approx. 350 ml. For adult male) Tidal volume minus dead

Dead air space Correct ans - anatomic dead space are structures that hold air but but can't participate in gas exchange. Physiologic dead space are alveoli or capillaries destroyed by disease
Expiratory reserve volume Correct ans - amount of gas that can be forcefully expired at the end of a normal expiration
Inspiratory reserve volume Correct Ans - amount of gas that can be forcefully inspired in addition to a normal breaths tidal volume
Internal respiration Correct ans - exchange of gases between blood cells and tissues
Peak expiratory flow Correct ans - the greatest rate of airflow during forced expiration when lungs are fully inflated
Residual volume Correct ans - after maximal forced exhalation, amount of air remaining not able to be expelled
Tidal volume Correct ans - amount of air in a respiratory cycle (500 ml, 5-7ml/kg)
Minute volume Correct ans - amount of gas moved in and out of respiratory tract per minute
Air trapping Correct ans - a respiratory pattern associated with an obstruction in the pulmonary tree. Rate increases to overcome resistance.
Angle of Louis Correct ans - angulation of the sternum that indicates the point where the second rib joins the sternum. (manubriosternal junction)
Anoxia Correct ans - total lack of oxygen available to the tissues Apnea Correct ans - respiratory arrest
Atelectasis Correct ans - abnormal condition characterized by collapse of alveoli, preventing exchange of CO2 and O2 in a part of the lungs
Barrier device Correct ans - thin film of material placed on the patient's face used to prevent direct contact with the patient's mouth during PPV
Carina Correct ans - where the trachea divides into right and left bronchi
Ronchi Correct ans - rattling or rumbling in the lungs. Inspiration and expiration. Fluid in larger airways and may be cleared from a cough.
Stridor Correct ans - harsh, high-pitched inspiratory sound best heard over the neck
Rattles (ronchi) Correct ans - inflammation and mucus or fluid in larger airways heard on inspiration. Associated with bronchitis or pneumonia
Crackles (rales) Correct ans - wet lungs - sounds like hair rolled in finger tips. fluid in smaller airways, crackling or popping sound on inspiration, sound that indicates presence of fluid in smaller airways
Croup Correct ans - viral infection in upper airway that sounds like a seal bark
Wheeze Correct ans - whistling sound heard on inspiration or expiration in pharynx, trachea, bronchi
Biot's respirations Correct ans - irregular respirations and rate with periods of apnea from increased ICP, brain damage at medulla, DKA, and OD'ing
Agonal respirations Correct ans - slow, shallow, irregular from anoxic brain injury
Central neurogenic hyperventilation Correct ans - similar to kussmaul respirations, deep and rapid breathing from increased ICP [Show Less]
