Atelectasis - Answer -airlessness or collapse of a lung, usually as a
result of hypoventilation or obstruction
Bi-level positive airway pressure (BiPAP) - Answer -a noninvasive,
ventilation-assistance modality that provides higher airway pressure

ventilation-assistance modality that provides a set positive airway
pressure throughout the patient's respiratory cycle

mucous membranes, due to excessive concentration of
deoxyhemoglobin in the blood
Dyspnea - Answer -difficult or labored breathing
Face tent - Answer -a soft, oxygen-delivery mask that fits under the
