Card Set Information
covers trachea during swallowing to prevent aspiration
Respiratory structure palpable just above the sternum is:
muscle that separates the chest and abdomen
normal resting tidal volume for an adult is:
the volume of air inspired and expired during one breath
total volume of air inhaled in a minute;tidal volume multiplied by respiratory rate.
Air pressure in lungs when contracted...
air pressure in lungs upon rest...
percentage of O2 normal atmospheric air contains
Portion of brain responsible for regulation of breathing
Most common complication of excessive or forceful ventilation is
O2 administration device with the highest O2 delivery to the patient is:
non rebreather mask
Most common airway obstruction
Correct ventilation for a non breathing adult is:
one breath every 5 seconds.
Describe Oropharyngeal airway measurement...
patient's mouth to angle of jaw
pocket mask with 15ml of O2 per minute achieves what percentage of concentration?
Maximum percentage of O2 delivery for a bag mask with O2 reservoir?
What color are O2 tanks?
Tank pressure full of O2 is usually what psi?
System used to avoid misplacement of a regulator an a portable O2 cylinder is called the what?
in index safety system
O2 system that is the most portable is what?
Regulators are designed to provide a safe pressure to the delivery device of approximately what psi?
When suctioning the upper airway, you should activate the negative pressure when?
when the tip is in the oropharynx
Lifting at the angle of the jaw while maintaining the head in the neutral inline position is called what?
modified jaw thrust
Best way to remove liquid from the airway is what?
Difference between respiratory failure and respiratory arrest?
respiratory failure is inadequate ventilation to support life. respiratory arrest is complete cessation of breathing.
Never suction for more than how many seconds?
Mouth to mask ventilation is most reliable method of positive pressure ventilation why?
allows EMT to create seal with 2 hands, feel chest wall rise and give supplemental O2
Bag mask ventilation is most common method of positve pressure ventilation used.
Define cricoid pressure
compression of the esophagus between the cricoid cartilage and thoracic spine to keep air from entering the esophagus and prevent gastric distention and regurgitation.
3 most common O2 devices and O2 they deliver
nasal cannula, 24-40%, pocket mask, 50% and nonrebreather up to 90%
Normal pulse oximetry level range
Signs of severe airway obstruction are what?
ineffective cough, high pitched noises while inhaling, inability to talk and possibly cyanosis
Plueritic chest pain is what?
pain made worse by breathing
Pulse oximetry measures what?
