Critical care Flashcards
what is an endotracheal tube
invasive artificial airway when unable to protect their own airway
plastic tube inserted into the trachea through mouth or nose
maintains an airway to deliver oxygen and positive pressure
breathing tube
what must you know about ETT tube
should be verified by chest X-ray
assess for equal breath sounds bilaterally
can become displaced into the R main stem bronchus
What is a tracheostomy tube
artificial airway used for long-term needs
soma is made in the neck and the tube inserted in trachea
what is a tracheostomy tube used for
tracheal obstruction
slow vent weaning tracheal damage
neuromuscular damage
must know for tracheostomy tube
infection prevention
only suction to premeasured depth
dont suction longer than 10 seconds
suctioning too deep can cause larynngospasm
daily trash care and suctioning
keep a back up at the table
what is peak inspiratory pressure
highest pressure in the lungs during inhalation
what is positive end expiratory pressure
amount of pressure in the alveoli at the end of expiration
what is fraction of inspired oxygen
how much oxygen the patient is getting 21-100 percent
what is tidal volume
the amount of air that is inhaled during one respiratory cycle
what is end-tidal carbon dioxide
the partial pressure of CO2 detected at the end of exhalation
what is room air
the atmospheric air we breath under normal circumstances 21%
What is a volume controlled ventilator mode
there is a certain volume of air delivered to the patient with each breath
what is pressure controlled ventilator mode
the lungs are inflated to a certain pressure
what is cpap
continuous positive airway pressure
what is bipap
bilevel positive airway pressure
