Flashcards in Airway management Chpt. 9 Deck (75):
Metabolism that can proceed only in the presence of oxygen.
Occasional, gasping breaths that occur after the heart has stopped.
The upper airway tract or the passage above the larynx, which includes the nose, mouth and throat.
The volume of air that reaches the alveoli. It is determined by subtracting the amount of "dead space" air from the "tidal volume".
A safety system for large oxygen cylinders, designed to prevent the accidental attachment of a regulator to a cylinder containing the wrong type of gas.
American Standard System
The metabolism that take place in the absence of oxygen; the principle product is lactic acid.
Absence of spontaneous breathing
In context of airway, the introduction of vomitus or other foreign materiel into the lungs.
Irregular, ineffective respiration that mat or may not have an identifiable pattern.
A ventilation device attached to a control box that allows the varibles of ventilation to be set. it frees the EMT to perform other tasks while the patient is be ventilated.
Automatic Transport Ventilator (ATV)
A device with a one-way valve and a face mask attached to a ventilation bag; when attached to a reservoir and connected to oxygen, delivers more than 90% supplemental oxygen.
A protective item, such as a pocket mask with a valve, that limits exposure to a patient's body fluids.
A body part or a condition that appears on both sides of the midline.
Subdivision of the smaller bronchi in the lungs; made of smooth muscles and dilate or constrict in response to various stimuli
Point at which the trachea bifurcates (divides) in to the left and right main stem bronchi (left and right lung)
Monitor the levels of O2, CO2, and the pH of the cerebrospinal fluid and then provide feedback to the respiratory centers to modify the rate and depth of breathing based on the body's needs at any given time.
The ability of the alveoli to expand when air is drawn in during inhalation.
A method of ventilation used primarily in the treatment of critically ill patients with respiratory distress; can prevent the need for endotracheal intubation.
Continuous Positive Airway Pressure (CPAP)
The portion of the tidal volume that does not reach the alveoli and thus does not participate in gas exchange.
A process in which molecules move from an area of higher concentration to an area of lower concentration.
Shortness of breath
The passive part of the breathing process in which the diaphragm and the interconstal muscles relax, forcing air out of the lungs.
The exchange of gases between the lungs and the blood cells in the pulmonary capillaries; also called pulmonary respiration.
A normal reflex mechanism that causes retching; activated by touching the soft palate pr the back of the throat.
A condition in which air fills the stomach, often as a result of high volume and pressure during artificial ventilation.
The space in between the voal cords that is the narrowest portion of the adult's airway; also called the glottic opening.
A term used to distinguish the degree of distress in patient with a mild airway obstruction. With good air exchange, the patient is still conscious and able to cough forcefully, although wheezing may be heard.
Good air exchange
A combination of two move-ments to open the airway by tilting the forhead back and lifting the chin; not used for trauma patients.
Head Tilt-chin life maneuver
Increased carbon dioxide level in the blood-stream.
A dangerous condition in which the body tissues and cells do not have enough oxygen
A condition in which chronically low levels of oxygen in the blood stimulate the respiratory drive; seen in patients with chronic lung diseases
The active, muscular part of breathing that draws air into the airway and lungs.
The exchange og gases between the blood ells and the tissues.
Bypassing of Oxygen-poor blood past nonfunctional alveoli to the left side of the heart
Technique to open the airway by placing the fingers behind the angle of the jaw and bringing the jaw forward; used for patients who may have cervical spine injury
Breathing that requires greater than normal effort; may be slower or faster than normal and usually requires the use of an accessory muscles.
A Complex structure formed by many independent cartilaginous structures that all work together; where the upper airway ends and the lower airway begins; also called the voice box.
Space within the chest that contains the heart, major blood vessels, vagus nerve, trachea, major bronchi and esophagus; located between the two lungs
The biochemical processes that result in production of energy from nutrients within the cells
Metabolism (cellular respiration)
Occurs when a foreign body partially obstructs the patient's airway. The patient is able to move adequate amounts of air, but also experiences some degree of repiatory distress.
Mild airway obstuction
The volume of air moved through the lungs in 1 minute minus the dead space; calculated by multiplying tidal volume (minus dead space) and respiratory rate; also referred to a minute volume.
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 flowrate.
Airway adjunct inserted into the nostril of an unresponsive patient, or a patient with an altered level of consciousness who is unable to maintain airway patency independently
Nasopharyngeal (Nasal) Airway
The nasal cavity; formed by the union of facial bones and protects the respiratory tract from contaminants.
A combination mask and a reservoir bag system that is the preferred way to give oxygen in the prehospital setting; delivers up to 90% inspired oxygen and prevents inhaling the exhaled gases (Carbon Dioxide)
Airway adjunct inserted into the mouth of an unresponsive patient to keep the tongue from blocking the upper airway and faciliate suctioning of the airway
Oropharyngeal (Oral) Airway
Forms the posterior portion of the oral cavity, which is bordered superiorly by the hard and soft palates, laterally by the cheeks, and inferiorly by the tongue.
The process of delivering oxygen to the blood by diffusion from the alveoli following inhalation into the lungs
Thin membrane that lines the chest cavity
The term used to describe the amount of gas in air or dissolved in fluid, such as blood.
Open, clear of obstruction
Nerve that innervates the diaphragm; necessary for adequate breathing to occur.
A system established for portable cylinders to ensure that regulator is not connected to a cylinder containing the wrong type of gas.
A partial or complete accumulation of air in the pleural space.
A term used to describe the degree of distress in a patient with a mild airway obstruction. Wit poor air exchange, the patient often has a weak, ineffective cough, increased difficulty breathing, or possible cyanosis and may produce a high-pitched noise during inhalation (stridor)
Poor air exchange
Mechanical maintenance of pressure in the airway at the end of expiration to increase the volume of gas remaining in the lungs.
Positive End-Expiratory pressure (PEEP)
An assessment tool that measures oxygen saturation of the hemoglobin in the capillary beds.
A side-lying position used to maintain a clear airway in unconscious patients without injuries who are breathing adequately
The air that remains in the lungs after maximal expiration
The process of exchanging oxygen and carbon dioxide
Movement in which the skin pulls in around the ribs during inspiration.
Occurs when a foreign body completely obstructs the patient's airway. Patients cannot breathe, talk, or cough
Severe airway obstruction
An opening through the skin and into an organ or other structure; a stoma in the neck connects the trachea directly to the skin
A high-pitched noise heard primarily on inspiration
A hollow, cylindrical device used to remove fluid from the patients' airway
A liquid protein substance that coats the alveoli in the lungs, decreases alveolar surface tension, and keeps the alveoli expanded; a low level in the premature infant contributes to respiratory distress syndrome.
A life-threatening collection of air within the pleural space; the volume and pressure have both collapsed the involved lung and caused a shift of the mediastinal structure to the opposite side.
The amount of air (in mL.) that is moved in or out of the lungs during one breath
Large, semi-rigid suction tip recommended for suctioning the pharynx; also called Yankauer tips.
Surgical opening into the trachea.
Exchange of air between the lungs and the environment, spontaneously by the patient or with assistance from another person, such as an EMT.
Thin membrane that covers the lungs
The amount of air that can be forcibly expelled from the lungs after breathing in as deeply as possible.
Thin white bands of tough muscular tissue that are lateral borders of the glottis and serve as the primary center for speech production
