In a five-year study of nearly 11,000 people, those with obstructive sleep apnea had a higher risk of sudden cardiac death. At greatest risk were those aged 60 and older with moderate to severe apnea (20 episodes an hour).
When their oxygen saturation levels dipped below 78 percent — preventing air from flowing into the lungs — their risk increased by 80 percent.

In case anyone asks why we are so harsh on untreated OSA quote this study.

During an average follow-up of 5.3 years, 142 patients had resuscitated or fatal SCD (annual rate 0.27%). In multivariate analysis, independent risk factors for SCD were age, hypertension, coronary artery disease, cardiomyopathy or heart failure, ventricular ectopy or nonsustained ventricular tachycardia, and lowest nocturnal O2sat (per 10% decrease, hazard ratio [HR]: 1.14; p = 0.029). SCD was best predicted by age >60 years (HR: 5.53), apnea-hypopnea index >20 (HR: 1.60), mean nocturnal O2sat <93% (HR: 2.93), and lowest nocturnal O2sat <78% (HR: 2.60; all p < 0.0001).
In a population of 10,701 adults referred for polysomnography, OSA predicted incident SCD, and the magnitude of risk was predicted by multiple parameters characterizing OSA severity. Nocturnal hypoxemia, an important pathophysiological feature of OSA, strongly predicted SCD independently of well-established risk factors. These findings implicate OSA, a prevalent condition, as a novel risk factor for SCD.
This study suggests that the consumption of green tea ≥2 times/d is associated with a reduced risk of COPD in Korean populations.
Consuming Green Tea at Least Twice Each Day Is Associated with Reduced Odds of Chronic Obstructive Lung Disease in Middle-Aged and Older Korean Adults
Drink more green tea.
Especially if you’re an older Korean.

Asthma mortality decreased by 42% in the United States between 1999 and 2015, with the largest decline observed among elderly patients, according to retrospective surveillance data.

It was only after it settled down that we realised what we had achieved. In a 24 hour period our emergency department would typically see around 200 patients. During “Thunderstorm Asthma,” over a 12-hour period between 7pm and 7 am we treated 296 patients; 208 of them had respiratory symptoms. Of these patients 170 went home, 36 were admitted including four that went to the intensive care unit. The peak occurred at 9pm, when 43 patients arrived in an hour. It wasn’t until 2am before our numbers dropped below 20 an hour.
