The patient is a composite written for a model paper.
Mr. D., a 49-year-old pharmaceutical sales representative, comes because his wife insists. She reports that he snores loudly every night and sometimes stops breathing, then gasps. He admits to daytime sleepiness and says that last month he drifted onto the rumble strip on the interstate after lunch. He drives about 800 miles a week. His BMI is 33, his neck circumference 43 cm (about 17 inches), and two office readings of his blood pressure averaged 146/92 mm Hg. This paper describes the evaluation and plan.
Screening Versus Evaluation
The U.S. Preventive Services Task Force found too little evidence to judge whether screening adults who have no symptoms of sleep apnea does more good than harm (U.S. Preventive Services Task Force et al., 2022). Mr. D. is not asymptomatic: he has snoring, witnessed apneas and sleepiness with a near crash. The question is not whether to screen but how to evaluate a symptomatic patient.
Estimating Probability With STOP-Bang
The STOP-Bang tool combines four symptom questions, loud snoring, daytime tiredness, observed pauses and treated or untreated high blood pressure, with four measured traits: BMI above 35, age above 50, a large neck and male sex. Chung et al. (2016) describe it as a practical tool in which a score of 0 to 2 suggests low risk, 5 to 8 high risk, with each additional point making significant sleep apnea more likely. Mr. D. scores yes for snoring, tiredness, observed apneas, high blood pressure, neck circumference and male sex, and no for BMI over 35 and age over 50: a score of 6, high risk.
The rumble strip is the finding that turns a sleep referral into a safety conversation today.
The Physiology
In obstructive sleep apnea, the upper airway repeatedly narrows or closes during sleep as muscle tone falls, especially in people with a large neck, excess fat around the airway or a crowded oropharynx. Each obstruction lowers oxygen levels and triggers a brief arousal to reopen the airway, fragmenting sleep. Repeated drops in oxygen and surges in sympathetic activity raise blood pressure and cardiovascular risk. Fragmented sleep causes daytime sleepiness and impaired attention, which explain his near miss.
Examination
Beyond his neck size and blood pressure, I examine his oropharynx, which shows a crowded airway with large tonsils and a low-lying soft palate, and his nose, which is patent. Heart and lung examinations are normal, and there are no signs of heart failure.
Choosing the Test
The American Academy of Sleep Medicine guideline supports either a laboratory study or a technically adequate home test for adults without complicating conditions whose symptoms and signs suggest moderate to severe disease, and advises against using questionnaires alone to diagnose it (Kapur et al., 2017). Polysomnography in a laboratory is recommended instead for patients with significant cardiopulmonary disease, neuromuscular conditions, suspected other sleep disorders or chronic opioid use. Mr. D. is uncomplicated, so I order a home sleep apnea test. If the home test is negative or inconclusive despite high suspicion, laboratory polysomnography should follow (Kapur et al., 2017).
How to Read the Home Test
A home test records airflow, breathing effort and oxygen saturation overnight and reports an apnea-hypopnea index, the number of breathing pauses and shallow breaths per hour. An index of 5 to 14 is mild, 15 to 29 moderate and 30 or more severe. Because home devices do not measure sleep itself, they calculate events per hour of recording rather than per hour of sleep, which can underestimate severity, one reason a negative home test in a high-probability patient should lead to laboratory testing (Kapur et al., 2017).
Why Not Diagnose From the Questionnaire
With a score of 6, it is tempting to call the diagnosis made. The guideline advises against diagnosing sleep apnea from questionnaires alone, because they cannot measure severity and have false positives (Kapur et al., 2017). Severity determines treatment options and coverage for positive airway pressure, so objective testing is necessary.
Drowsy Driving
His near crash requires immediate attention. I advise Mr. D. not to drive when drowsy, to avoid driving after lunch and on long trips until treated, to pull over and nap if sleepy and to consider asking his employer for temporary changes. I document this counseling. His state does not require clinician reporting for sleep apnea, but I explain that untreated sleepiness increases crash risk substantially.
Blood Pressure
His elevated blood pressure may improve with treatment of sleep apnea, but it also needs its own management. I plan home readings and will start treatment if they confirm hypertension.
Treatment If Confirmed
Positive airway pressure therapy is the standard treatment for moderate to severe obstructive sleep apnea, keeping the airway open with pressurized air through a mask. Weight loss, avoiding alcohol before bed, sleeping on his side and treating nasal congestion help as well. Oral appliances made by a dentist are an alternative for mild to moderate disease or for those who cannot tolerate positive airway pressure.
Other Contributing Factors
Mr. D. drinks two beers most evenings and sometimes uses a store-bought antihistamine sleep aid in hotel rooms. Alcohol and sedating antihistamines relax upper airway muscles and worsen obstruction. I recommend avoiding both, especially in the evening, while testing and treatment proceed.
Cardiovascular Implications
Untreated moderate to severe sleep apnea is associated with hypertension that is harder to control, atrial fibrillation and other cardiovascular problems. If Mr. D.'s blood pressure remains high after treatment of sleep apnea, it will be treated on its own terms. I also ask about palpitations, which he denies, and check his pulse, which is regular, and I will repeat an electrocardiogram if symptoms appear.
His Work
Mr. D. drives for his job, and a diagnosis could affect his work. I reassure him that people whose sleep apnea is under treatment keep driving safely every day, and that alertness usually improves within weeks of consistent use of the device. Ignoring it would put his job and his life at greater risk.
Partner's Sleep
His wife has been sleeping in another room because of his snoring. Treatment often helps both partners, and I invited her to the follow-up visit, since partners often notice improvement first.
Follow-Up
I will review the home test with Mr. D. and refer him to sleep medicine for positive airway pressure setup if confirmed, then check adherence and symptoms at four to six weeks, since early adherence predicts long-term use.
Conclusion
Mr. D.'s snoring, witnessed apneas, sleepiness, large neck and elevated blood pressure give him a STOP-Bang score of 6 and a high probability of obstructive sleep apnea. As a symptomatic, uncomplicated adult, he is a candidate for home sleep apnea testing under the guideline. His near crash makes drowsy driving counseling as urgent as the diagnosis, and treatment with positive airway pressure is likely to improve both his sleepiness and his blood pressure.

How this NRP 555 Week 3 example is structured
The NRP/555 Week 3 work usually presents an adult respiratory condition and asks for assessment and management. This paper takes a sleep-related breathing disorder through the steps a primary care clinician controls: recognizing it, estimating probability, choosing the right test, addressing immediate safety and planning treatment and follow-up. Students search this week as NRP 555 Week 3, NRP555 Wk 3 or NRP/555 Wk 3; all three are the same assignment.
NRP/555 Week 3 questions, answered
What does NRP/555 Week 3 usually ask for?
Many sections present an adult respiratory case, such as asthma, COPD or a sleep-related breathing disorder, and ask for evaluation and guideline-based management.
What is the STOP-Bang questionnaire?
An eight-item screening tool asking about snoring, tiredness, observed apneas, high blood pressure, BMI over 35, age over 50, neck circumference over 40 cm and male sex; higher scores indicate higher probability of moderate to severe sleep apnea.
Can sleep apnea be diagnosed with a home test?
Yes, for uncomplicated adults with signs and symptoms of increased risk of moderate to severe obstructive sleep apnea, according to the American Academy of Sleep Medicine guideline.
