Chapter 10 Flashcards
(88 cards)
Agonal respirations
Gasping type respirations that have no pattern and occur very infrequently; a sign of impending cardiac or respiratory arrest
Adam’s apple
The bulky cartilage that forms the anterior portion of the Larynx
Alveolar ventilation
The amount of inspired air that reaches the alveoli of the lungs
Alveoli
The air sacs of the lungs
Automatic transport ventilator
A positive pressure ventilation device that delivers ventilations automatically
Bag valve mask (BVM) device
A positive pressure ventilation device that consists of a bag with a non-rebreather valve and a mask. The bag valve device is connected to the mask or other airway. The bag is squeezed to deliver a ventilation to the patient.
Bilaterally
On both sides
Bilevel positive airway pressure (BiPAP)
A form of noninvasive positive pressure ventilation. The BiPAP device delivers a continuous flow of air under pressure. It differs from the CPAP device in that it provides different pressures: higher during inspiration, lower during expiration.
Bradypnea
A breathing rate that is slower than the normal rate
Bronchi
The two main branches leading from the trachea to the lungs, providing the passageway for air movement
Bronchioles
Small branches of the bronchi
Carina
The point at which the trachea splits into the right and left mainstream bronchi
Chemoreceptors
Receptors that constantly monitor the arterial content of oxygen, carbon dioxide, and the blood pH and stimulate a change in respiratory rate and depth
CPAP - continuous positive airway pressure
A form of noninvasive positive pressure ventilation. The CPAP device delivers a continuous flow of air under pressure
Cricoid cartilage
The most inferior portion of the larynx and only for cartilaginous ring of the upper airway. It is felt immediately below the thyroid cartilage
Cricoid pressure
Pressure applied to the cricoid cartilage to compress the esophagus
Crossed fingers technique
it’s technique in which the thumb in the index finger are crossed with the thumb on the lower incisors and the index finger on The upper incisors. The fingers are moved in a snapping or scissor motion to open the mouth
Crowing
A sound similar to that in the cawing Crow that indicates that the muscles around the larynx are in spasm and beginning to narrow the opening into the trachea
Cyanosis
A bluegray color of the mucous membrane and/or skin, which indicates in adequate oxygenation or poor perfusion
Dead airspace (Vp)
Anatomical areas in the respiratory tract (outside the alveoli) where air collects during inhalation of the new gas exchange occurs
Deoxygenated
Containing low amounts of oxygen, as with venous blood
Diaphragm
The major muscle of respiration that separates the chest cavity from the abdominal cavity
Epiglottis
Is small, leaf shaped flap of cartilaginous tissue, located immediately posterior to the root of the tongue, that covers the opening of the lyrics to keep food and liquid from entering the trachea and lungs
Exhalation/expiration
The passive process of breathing air out of the lungs
