What is hypoxic drive EMT quizlet?
Hypoxic Drive. patients who are stimulated to breath by low levels of oxygen in the blood; in a normal person, respiratory drive influenced by increasing CO2 in the blood.
For which of these disease processes would Continuous Positive Airway Pressure be most beneficial?
Modes of ventilation
Most patients who are provided noninvasive ventilation are provided support with pressure ventilation, with continuous positive airway pressure (CPAP), which is the most basic level of support. CPAP may be especially useful in patients with congestive heart failure or obstructive sleep apnea.
Which of these statements indicates that the EMT has a correct understanding of the use of oxygen in the prehospital setting?
Which of these statements indicates that the EMT has a correct understanding of the use of oxygen in the prehospital setting? “Oxygen should never, ever be withheld from a patient whom you think may need it.”
For which of these patient is placement of an oropharyngeal airway indicated?
For example, if you perform a head tilt-chin lift maneuver or jaw thrust on a patient to open their airway and are not able to ventilate the patient successfully, placement of an OPA is indicated.
What is hypoxic drive EMT?
Normally when carbon dioxide levels increase, it triggers a person to breathe deeper and faster. In people who have chronically high levels of carbon dioxide, the body gets used to the high levels and instead begins to base the drive to breathe on low oxygen levels. This is referred to as hypoxic drive.
What is hypoxic drive?
When hypoxemia exists with chronic hypercapnia, the central response to carbon dioxide is blunted, and the primary stimulus to breathe is mediated through hypoxic stimulation of the peripheral chemo- receptors. This is known as the hypoxic drive, and it is real.
What is a positive airway pressure device?
Positive airway pressure (PAP) treatment uses a machine to pump air under pressure into the airway of the lungs. This helps keep the windpipe open during sleep.
When should CPAP be used?
It should be used on patients who are alert and able to follow commands, show signs of respiratory distress, have rapid breathing, and a pulse oximetry of less than 90%. It is important, however to follow your protocols on when to use CPAP.
Which statement indicates that the EMT has an accurate understanding of the bronchioles?
Which of the following statements indicates that the EMT has an accurate understanding of the bronchioles? “They are all passages located in the lower airway that have smooth muscle surrounding them.”
Which statement made by an EMT shows that she understands how do you suction patients in a field setting?
Which one of the following statements made by an EMT shows that she understands how to suction patients in a field setting? “I only activate the suction device when I am withdrawing the suction catheter.”
What is the function of pulmonary surfactant EMT quizlet?
the presence of pulmonary surfactant causes a decrease in alveolar surface tension, thus impairing the exchange of gases in the lungs. alveoli and an overall decrease in blood oxygen levels. returns to the left side of the heart in an unoxygenated state.
