Airway Management Flashcards
How long does it take for brain tissue to die without oxygen?
4-6 minutes
Oxygen reaches body tissues and cells through…
Breathing and circulation
Diffusion
When oxygen moves from the atmosphere into the lungs, then crosses the alveolar membrane onto hemoglobin.
Ventilation
Is the exchange of air between the lungs and the environment.
The diaphragm of chest wall muscles are responsible for what?
The regular chest rise and fall the accompany with normal breathing.
Upper airway
Nasopharynx, Nasal air passage, Pharynx, Oropharynx, Mouth, Epiglottis, Larynx
Upper airway functions
Warm, filer and humidity air as it enters the body.
Pharynx (Throat)
Is a muscular tube that extends from the nose to the mouth. Composed of the naso, Oro, laryngo.
Larynx
Is where the upper ends and the lower begins.
Thyroid
Adam’s apple
Glottis
Also called the glottic opening is the space between the vocal cords and the narrowest portion of the adults airway.
Trachea
Is the conduit for air entry into the lungs. 10-12 cm long
Pleura
The membrane that surrounds the lungs.
Visceral pleura
What the lung tissue is cover by.
Parietal pleura
Lines the inside of the thoracic cavity. There is a small amount of fluid between the visceral and pleura serves as a lubricant to prevent friction during breathing.
Ventilation
The physical act of moving air in and out of the lungs
Oxygenation
The process of loading oxygen molecules onto hemoglobin molecules in the bloodstream
Respiration
The actual exchange of oxygen and carbon dioxide in the alveoli as well as tissues in the body.
Inhalation
The active muscular part of breathing.
Cheyne stokes breathing
Rapid shallow breaths with periods of apnea.
Stroke and serious head injuries.
Kussmaul Respirations
DEEP Rapid respirations commonly seen with patients with metabolic acidosis.

15 in adults
10 in children
5 in infants Then ventilate for 2 minutes.
