pump enough blood to meet the demands of the body. It typically occurs
within 24 hours of an AMI
The average concentration of oxygen in a titration for treatment is
between: - ANSWER - 95% and 99%

Your EMS unit is called to a private residence at 3:00 am for difficulty

who has had a lower grade fever for the past three days. Her mother says
the patient woke up with a seal-bark cough and difficulty breathing.

humidified oxygen
Ex: the "seal-bark" cough is known as croup, which often responds well
to the administration of humidified oxygen
You and your partner are at the station when you hear a frantic knock on
the front door. A man says his three year old daughter is in his car's back
seat, with a sudden onset of difficulty breathing, sore throat, and a high
fever. As you approach the patient, you notice she is in a tripod position
on her mom's lap, she looks very ill, and is drooling. What problem do
you suspect and how would you treat her? - ANSWER - Epiglottitis. The
best treatment is to treat the patient gently and do not cause them to cry.
Transport in a position of comfort with high flow oxygen, if tolerated.
Transport rapidly, but quietly so as not to alarm the child.
Your unit is dispatched to a private residence for a possible choking. You
arrive on scene and find a four year old female who was pulled out of
the pool by her father. He states she was underwater for a minute or two,
and she vomited a small amount when he pulled her out. There is
remaining vomit in her mouth and airway, and she is apneic. What is the
maximum time you are allowed to suction your patient before
oxygenating them? - ANSWER - 10 seconds
Ex: "do not withhold oxygen for more than 15 seconds for adult patients,
