From the atmosphere, what structures does air pass through during ventilation? - ANSWERStarts in atmosphere, then nose, nasopharyngeal space/orophargyneal space (if mouth breather), then pharynx, larynx, trachea, bronchi, bronchioles, alveoli What is the purpose of the nasal passages and nasopharynx? - ANSWERTo warm/humidify air as it passes through What is the difference between respiration and ventilation? - ANSWERRespiration refers to the exchange of gases in the alveoli, ventilation re...

Aerobic metabolism - ANSWERmetabolism that can only proceed in the presence of oxygen Agonal Gasps - ANSWERoccasional, gasping breaths that occur after the heart has stopped Airway - ANSWERThe upper airway tract or the passage above the larynx, which includes the nose, mouth, and throat. Alveolar minute volume - ANSWERThe volume of air moved through the lungs in 1 minute minus the dead space; calculated by multiplying tidal volume (minus dead space) and respiratory rate. Alveolar ven...

subcutaneous emphysema - ANSWERthe presence of air in the subcutaneous tissue (crackling under the skin, swelling and bruising around neck, sore throat/wheezing, can indicate pneumothorax) traumatic asphyxia - ANSWERintense compression of the thoracic cavity, causing venous back-flow from the right side of the heart into the veins of the neck and the brain (ex. motor vehicle accidents, industrial and farming accidents; swelling of face/neck; cyanosis, distended neck vein; subconjunctival ble...

Which of the following would cause an increase in the amount of exhaled carbon dioxide? - ANSWERIncreased cardiac output All of the following are signs of hypoxia except - ANSWERdehydration Inhalation occurs when the - ANSWERdiaphragm and intercostal muscles contract and cause a decrease in intrathoracic pressure. Based on current guidelines in which of the following situations should supplemental oxygen be administered - ANSWERExposure to carbon monoxide and an oxygen saturation of 95%...

Hypoxia - ANSWERLow oxygen saturation of the body, not enough oxygen in the blood. Will disrupt normal function Hypercapnia - ANSWERexcessive carbon dioxide in the bloodstream, typically caused by inadequate respiration. Respiration - ANSWERthe diffusion of O2 & CO2 between the aveoli & the blood (pulmonary respiration) & between the blood & the cells (cellular respiration) Also used to mean simply breathing alveolar ventilation - ANSWERthe amount of air that reaches the alveoli arti...
