mod 3 air way cht 10

TermDefinition
pulmonary ventilation mechanical process air moves in and out of the lungs, air is pulled in, pushed out the chest cavity
External Respiration Gas exchange between alveoli and pulmonary capillaries Oxygenates and removes carbon dioxide from the lungs
Internal Respiration Gas exchange between the systemic capillaries and cells. Delivery of oxygen to cells and removal of carbon dioxide
Aerobic Metabolism (Cellular Respiration) Aerobic metabolism need O2 to break down glucose, make ATP By products of aerobic metabolism are WATER and CARBON DIOXIDE
Upper Airway Extends from the nose and mouth to cricoid cartilage( above vocal cords) at inferior edge of larynx
Epiglottis Protects lungs, may fail to close in unresponsive patients, in altered mental status, muscle relaxation can cause epiglottis to obstruct larynx
Bronchioles Contain smooth muscle, which can contract and narrow the air passage.
Parietal Back of ribs surrounds lungs
Viscerail Is actually on the surface of the lungs
Diaphragm Provides 60% to 70% of the effort of breathing (biggest muscle for breathing.
Inhalation External intercostal muscles & Diphram contract. - Chest cavity increases in size - pressure in the chest cavity decreases- air is drawn in through the nose and mouth. (this requires energy)
Exhalation External intercostal muscles & diaphragm relax - Chest cavity Decreases in size - Pressure in the chest cavity Increases - air is pushed out through the nose and mouth
Brainstem Recive input from chemoreceptors about the levels of oxygen, carbon dioxide and pH
Respiration Is the p[recess of gas exchange
Oxygenation and removal of carbon dioxide occur as result of external and internal respiration
Hypoxemia Is a low oxygen content in arterial blood that may occur.
Hypoxia Inadequate oxygen is being delivered to the cells. it may occur from airway obstruction inadequate breathing andf shock
Alveolar/Capillary exchange Gases move from areas of higher concentration to areas of lower concentration. Carbon Dioxide diffuses from capillaries into alveoli oxygen diffuses from the alveoli into the blood and is bound to hemoglobin
Capillary/ cellular exchange Blpood entering capillaries is high in oxygen, which diffuses into cells. Cells are high in carbon dioxide, which diffuses into the blood.
Anerobic metabolism results in Insufficient energy production Buildup of lactic acid Cell Dysfunction
Pulmonary Ventilation may be impaired by Interruption of nervous control Damage to thorax Increased airway resistance Loss of airway patency
Gas exchange may be impaired by Decreased ambient oxygen content Lung disease, drowning Toxic gases
Poor perfusion also leads to cellular hypoxia Obstructed forward movement of blood, Hypovolemia
Signs of an open airway Air can be felt and heard moving in and out of the mouth and nose The patient is speaking in full sentences or with little diffucilty THe sound of the voice is normal for the patient
Signs of a blocked or inadequate airway Abnormal upper airway sound An awake patient who is unable to speak Evidence of a foregn body airway obstruction ( tongue, food, vomit, blood, or teeth in the upper airway, mouth or nose Swelling to the mouth, tongue or oropharynx
Upper airway sounds Snoring, crowing, gurgling, stridor
Opening the airway Manual maneuvers, suction, mechanical airways
Head- tilt chin- lift maneuver Used when NO spinal is suspected used in unresponsive patients, cardiac arrest Must be supplemented with a mechanical airway of ineffective on its own ( fixs snoring)
Jaw thrust maneuver Used when spincal injury IS suspected Allows neck to remain in neutral, in- line position
Recovery position Used if a patient has an altered mental status and is at risk of aspiration contraindicated in suspected spinal injury and patients who need posititive pressure ventilation
Suction Gurgling indicates liquid in the airway use suction to remove blood, vomitus, secretions, and any other liquids, food particles, or objects from the mouth and airway
Standard precautions during suctioning Protective eyewear, mask, gloves, N-95 or HEPA respirator for suspected tuberculosis
Suction equipment Maybe be mounted in the ambulance or portable Must generate enough vacum and airflow to clear the airway must have wide-bore, thick tubing, a collection bottle, and water supply
