Chapter 14-Provide Artificial Ventilations Flashcards
ventilations can be given by
One or two EMS providers
In the pre-hospital environment you should use the following device when administering ventilation
Bag mask device
If possible, use devices that supply
Supplemental oxygen
Devices that have a ________ will provide higher percentages of oxygen to the patient
Oxygen reservoir
regardless of whether you ventilate the patient with or without supplemental oxygen, you should observe for
you should observe the chest for visible rise and fall to assess the effectiveness of your ventilations
The process of ventilating too fast or with too much force is known as
Hyperventilation
hyperventilation can lead to increased
Intrathoracic pressure known as pressure inside the chest cavity
why does hyperventilation lead to increased intrathoracic pressure?
because it puts pressure on the Vena cava, reducing the amount of blood returned to the heart
this increase in intrathoracic pressure decreases the effectiveness of chest compressions, and results in
The brain and the heart receiving decreased amounts of oxygen
What is ventilation?
The physical act of moving air in and out of the lungs
ventilation is required for adequate
Respiration
Ventilation can be disrupted by
trauma to the chest, foreign body airway obstruction, or an injury to the spinal cord that disrupts the phrenic nerve that innervates the diaphragm
