West Coast EMT block 2 study guide
An oxygen-delivery device in which oxygen flows through two small, tubelike prongs that fit into the
patient's nostrils
delivers 24% to 44% supplemental oxygen, depending on the flow rate.
1-6 or 1-4 L/min - answers✔✔nasal cannula
1000 and 1600 - answers✔✔A BVM bag will hold between _____ and _____ mL of air.
500 (Child BVM) - answers✔✔BVM's must have a volume of at least _____mL for newborns and infants.
bag valve mask; 15 L/min of 100% oxygen - answers✔✔BVM
Nonrebreathing mask used for patients who are breathing adequately but are suspected of having or
showing signs of hypoxia.
10-15L/min flow rate provides up to 95% inspired oxygen - answers✔✔What is a NRB and when do you
use it?
an oxygen-delivery apparatus consisting of a mask with holes on each side that allow exhaled air to
escape and color-coded entrainment ports that are adjustable to allow regulation of the concentration
of oxygen delivered
24%-44% oxygen (medium flow device) - answers✔✔Venturi mask
When it's continuously positive, it means there's air constantly being pushed in, in this case to help keep
those alveolar sacs inflated - answers✔✔CPAP (continuous positive airway pressure)
technique of artificial ventilation that involves the use of a pocket face mask with one-way valve to blow
air into the mouth of a patient - answers✔✔Mouth to Mask Ventilation
, A noninvasive method to quickly and efficiently provide information on a patient's ventilatory status,
circulation, and metabolism; effectively measures the concentration of carbon dioxide in expired air
over time. - answers✔✔Capnography
The buildup of excess base (lack of acids) in the body fluids. pH > 7.45 - answers✔✔Alkalosis
brainstem neurons that respond to changes in pH of cerebrospinal fluid
Located in the medulla
Increase RR and tidal volume to get rid of CO2
Primary mechanism of breathing - answers✔✔Central chemoreceptors
Receptors in the carotid arteries and the aorta that monitor blood pH to help regulate ventilation rate.
Back up mechanism of breathing (hypoxic drive) - answers✔✔Peripheral chemoreceptors
Heart rate x stroke volume, the overall performance of the heart - answers✔✔Cardiac output
movement of air in and out of the lungs - answers✔✔Ventilation
Brings oxygen into the body. Gets rid of carbon dioxide. - answers✔✔respiratory system
SA node, AV node, Bundle of His, Purkinje fibers - answers✔✔Electrical conduction system
carotid, brachial, radial, femoral, popliteal, posterior tibial, dorsalis pedis - answers✔✔Pulse locations
Inner layer of skin - answers✔✔Dermis
outermost layer of skin - answers✔✔Epidermis
under the skin - answers✔✔subcantaneous
