Question | Answer |
---|---|
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 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) |
