The trachea branches at this point to form the two mainstem bronchi.
What is the carina?
This condition occurs when oxygen levels are low.
What is hypoxia?
This device is used to perform mouth-to-mask ventilation.
What is a pocket face mask?
This item helps maintain a seal between an oxygen cylinder and regulator.
What is a gasket?
A chest pain patient with sudden respiratory distress who refuses a nonrebreather mask may better tolerate this device.
What is a nasal cannula?
This structure is found in the lower airway.
What are the bronchi?
Two signs of hypoxia include cyanosis and this change in patient status.
What is deterioration of mental status?
This mask may be used for supplemental oxygen administration in a patient with a stoma.
What is a tracheostomy mask?
This is the safe residual pressure for an oxygen cylinder.
What is 200 psi?
A patient with dentures who is being ventilated without difficulty should have dentures handled this way to maintain a good mask seal.
What is leave the dentures in place?
In pediatric patients, this structure is easily obstructed by swelling.
What is the trachea?
These two gases are measured by chemoreceptors that stimulate the normal urge to breathe.
What are carbon dioxide and oxygen?
Before applying a nonrebreather mask, the EMT should inflate this part and ensure it does not deflate during inspiration.
What is the reservoir bag?
This type of oxygen flowmeter can only be used upright.
What is a pressure-compensated flowmeter?
A patient with cyanosis, profuse sweating, and rapid shallow respirations should first receive this intervention.
What is assisted ventilation with a bag-valve mask and supplemental oxygen?
Air moves into the alveoli, blood travels through pulmonary capillaries, and this process allows gas exchange.
What is diffusion?
Respiratory distress becomes respiratory failure when the body can no longer keep up with oxygen demand and these two findings change.
What are skin color and mental status?
Venturi masks are designed to mix oxygen with this.
What is inhaled air?
An E cylinder with 2,000 psi flowing at 10 liters per minute would normally last about this long.
What is 50 minutes?
If aggressive bag-valve-mask ventilation causes a strong pulse to weaken, the EMT should adjust the ventilations this way.
What is reduce the volume of the ventilations?
The movement of oxygen and carbon dioxide across cell membranes from capillaries is called this.
What is internal respiration?
End-stage COPD can change the breathing stimulus from high carbon dioxide levels to this trigger.
What are low oxygen levels?
Connecting high-flow oxygen to the oxygen inlet on a pocket mask provides approximately this oxygen percentage.
What is 50%?
If a yellow cylinder will not accept the oxygen regulator, the EMT should take this action.
If a yellow cylinder will not accept the oxygen regulator, the EMT should take this action.
A patient with chronic bronchitis, respiratory distress, and a respiratory rate of 32 should have oxygen increased, and if breathing decreases, the EMT should do this.
What is assist ventilations with a bag-valve-mask device?
A patient with major internal abdominal bleeding needs oxygen because reduced circulating volume decreases this blood function.
What is the ability to transport oxygen and carbon dioxide?
