O2 -ation

test 2

dyspnea difficult or laboroed breathing
hypoxia not enough oxygen reaching the cells and tissues
Hypoxemia decreased levels of oxygen in blood
hypercapnia increased carbon dioxide levels
what percentage of breathed air is oxygen 21%
diffusion moving from areas of higher concentration to areas of lower concentration
part of brain which regulates respiration medula oblongota
What is the drive for healthy people to breath? drive to excrete excess CO2
What is the drive for a person with impaired lung function to breath? drive is called Hypoxic Drive and is the drive to take in more oxygen.
Too much oxygen therapy to a patient with COPD knocks out their hypoxic drive and causes them to have slowed or ceased breathing.
Carbon monoxide exposure carbon monoxide binds more easily to hemoglobin and crowds out any space for oxygen to bind.
how does obesity, chest injury and abdominal surgery affect oxygen levels decreased lung expansion and thus more shallow breaths limiting oxygen intake
how does anemia affect oxygen levels lower amount of red blood cells = lower amounts of oxygen being carried to cells
what types of drugs are most common cause of slowed respirations narcotics
threat and symptoms of hypoxia life-threatening and needs immediate attention. confusion, irritability, fatigue, increased heart rate, nasal flaring, pallor, and or cyanosis.
tachypnea increased respirations
bradypnea slowed respirations
hyperventilation rapid/deep breathing, causes excessive air in lungs and more CO2 exhaled than being produced
hypoventilation slow/shallow breathing, more CO2 is retained than is being exhaled
Apnea absence of respirations
Cheyne Stokes periods of rapid and deep breathing followed by slow/shallow, with periods of apnea.
orthopnea inability to breath except in an upright position
Kussmauls increased rate/depth greater than 20/min
Respiratory arrest failure to resume breathing after apneic episode
what to ask when taking respiratory history past respiratory problems, any current prob., family history, medications, exposures, signs and symptoms, smoking etc.
assessing oxygenation skin color and temp, level of consciousness, orientation, mucous membranes moist pink and intact, circulation, respirations, cough present or not and whether productive or not, nail clubbing, chest size and shape, breath sounds, pulse oximetry.
barrel chested increased anterior and posterior diameter
funnel chested depressed lower sternum
pigeon chested protruding upper sternum
if you hear an adventitious sound, you should... have the patient cough and relisten
what pulse oximetry reading need to be reported immediately? anything under 90, depending on the patient
nursing techniques to promote oxygenation positioning, breathing techniques, incentive spirometer
pursed lip breathing helps patient to develop control over their breathing and keeps airway open.
how to pursed lip breath inhale slowly through the nose count to 2, exhale slowly through pursed lips to count of 4
diaphragmatic breathing for patients who are short of breath- conscious use of diaphragm during breathing helps to conserve energy.
how to diaphragmatic breath patient places one hand over abdomen and one hand on chest, focus on pushing abdomen out during inspiration
what does hydration do for secretions and breathing? It thins secretions; also beneficial is humidification and nebulizer
chest physiotherapy percussion and postural drainage- percussing to loosen and positioning to let gravity pull secretions out of lungs.
diffeerent types of oxygen delivery systems nasal cannula, simple rebreather mask, partial rebreather mask, non-rebreather mask, venturi mask, face tent, tracheostomy collar, T-piece, nasal catheter, O2 tent, CPAP mask
what concentration of O2 is given with a partial rebreather? 35-60%
Most accurate delivery of O2 Venturi mask
hazards with oxygen use flammable and Oxygen toxicity
best time for sputum specimen? morning before meals
Nursing diagnosis related to oxygenation ineffective Airway Clearance, impaired gas exchange, ineffective breathing pattern, activity intolerance, knowledge deficit
