NURS 4750 EXAM 1
Barotrauma
damage to the lungs by positive pressure
Carina
the point at which the trachea branches into the right and left mainstem bronchi
Ventilatory weaning
process of going from ventilatory dependence to spontaneous breathing
End Tidal carbon dioxide detector
fits between the ET tube and the breathing circuit and uses a pH sensitive indicator that
changes color in response to different concentrations of carbon dioxide
Lung compliance
the quality of elasticity of the lungs
minute ventilation
volume of gas inhaled or exhaled from a persons lungs per minute
tidal volume
lung volume representing the normal volume of air displaced between normal inhalation
and exhalation when extra effort is not applied
extubation
Removal of endotracheal tube
Obturator
used to insert a tracheostomy tube, it contains a lock so the tube will not be coughed out
fraction of inspired oxygen
the oxygen level delivered to the patient
PEEP
positive pressure exerted during expiration

, NURS 4750 Exam
airway resistance
pressure difference between mouth and alveoli, divided by airflow. Defined as the change
in transpulmonary pressure required to produce a unit flow of gas through the airways of
the lung
intubation
the insertion of an ET tube
Ventilator mode
the method of inspiratory support
BiPAP
Bi-level positive airway pressure- newer form of pressure cycled ventilator in which the
ventilator provides a preset inspiratory pressure and an expiratory pressure similar to
PEEP
Endotracheal tube
flexible plastic tube that is placed through mouth into the trachea to help a patient
breathe, it is then connected to a ventilator, which delivers oxygen to the lungs
ventilatory dependence
failure to wean the patient from the ventilator while hospitalized in the ICU or respiratory
care center
Agonal breathing
gasping respiration - abnormal pattern of breathing and brainstem relfex characterized by
gasping, labored breathing, accompanied by strange vocalizations and myoclonus
tracheostomy
the tracheal stoma, or opening, that results from a tracheostomy (establishes airway)
ventilator rate
measure of how many breaths per minute the ventilator should be on or how many
breaths pre minute the patient takes
CPAP
