Apnea, Atelectasis, Pneumonia, Fungal Infections, TB, Pulmonary Edema

Describe Apnea The cessation of spontaneous respirations that lasts longer than 20 seconds.
Describe Hypopnea Condition characterized by shallow respirations with a 30-50% reduction in airflow.
Describe the pathophysiology of OSA (apnea) (Include length of obstruction, hypo/hyper-gas levels, avg.# of times a night) Apnea occurs when the tongue falls backwards and obstructs the pharynx. Obstruction can last from 15-90 seconds and causes severe hypoxemia and hypercapnia. It can occur as often as 200-400 times a night.
What are the risk factors for forming sleep apnea? increased body weight, age, neck circumference, craniofacial abnormalities More common in men than women
How is apnea manifested? frequent awakening at night, excessive daytime sleepiness, witnessed apneic episodes, snoring, morning headache, irritability
What are some complications that can occur r/t apnea? hypertension, right-sided heart failure, diminished ability to concentrate, impaired memory, interpersonal difficulites, depression, impotence
Describe polysomnography. The patient's chest and abdominal movement, oral airflow, nasal airflow, SpO2, ocular movement, and heart rate and rhythm and monitored
What monitors are used during a sleep study? polysomnography and pulse oximetry
What nursing and collaborative management should be done for a patient that has mild apnea? avoiding sedatives before sleep & weight loss are the most effective. oral appliances to bring the mandible and tongue forward and support groups are also helpful
What does CPAP stand for and who would it benefit the most? CPAP- continuous positive airway pressure used for patients with more severe symptoms of apnea
Describe how CPAP works. The pt. applies a nasal mask that is attached to a high-flow blower that is adjusted to maintain a positive pressure to the airway during ventilation to prevent airway collapse. (Lewis 543)
What does BiPAP stand for and who would it benefit the most? Bilevel positive airway pressure Best used for people with severe apnea that have a cardiac problem or have difficulty with the continuous pressure of the CPAP.
Describe how BiPAP works. BiPAP delivers a higher pressure during inspiration and a lower pressure during expiration
During patient teaching r/t use of CPAP or BiPAP you would tell them that: Irritation of eyes and nose can be controlled with ________________ Humidification This irritation is one reason that people do not comply with use of their masks, teaching them how to avoid it will help with compliance.
Describe Uvulopalatopharyngoplasty (UPPP) It is a surgical measure done to manage sleep apnea. It has a 60% success rate. It is removal of the tonsillar pillars, uvula, and posterior soft palate (removes obstructing tissue)
Describe Genioglossal Advancement and Hyoid Myotomy (GAHM) It is a surgical procedure done to manage sleep apnea. It has a 60% success rate.

What does a bilateral fractured nose look like? it's the most common, gives the nose a flat look (black eyes)
What does a complex fractured nose look like? caused by powerful frontal blows that usually involve damage to adjacent facial structures (teeth, eyes) swollen across the whole face
What nursing assessments/manifestation are r/t a fracture? epistaxis may be only sign- assess the ability to breath; presence of edema, bleeding, or hematoma; clear drainage from nose suggests CSF leak
What nursing management is done for a fractured nose? maintain airway (upright); reduce edema (apply ice); prevent complications (i.e. infection and respiratory compromise); provide emotional support (surgery, having a different looking face)
