💡TL;DR: Most healthy adults keep oxygen saturation around 95–100% during sleep, with only small dips. Brief drops into 90–94% can be normal, but levels that stay below 90% suggest a breathing problem and need a doctor's review. ≤88% for several minutes is dangerous and warrants

💡TL;DR: RSV symptoms usually start 4–6 days after exposure (range 2–8 days). You’re contagious for about 3–8 days and can spread it 1–2 days before symptoms; infants and people with weak immune systems may shed up to 3–4 weeks (CDC). Most illnesses last

💡 TL;DR: Yes, you can have RSV and pneumonia at the same time. RSV can cause viral pneumonia within a few days (often around days 3 to 5), or set up a secondary bacterial pneumonia. Highest risk: infants, adults 65+, and people with lung or immune problems. Expect supportive care

💡 TL;DR: Ohtuvayre (ensifentrine) is a new twice-daily nebulized maintenance medicine that can help reduce COPD flare-ups and improve daily breathing. In clinical trials, people had about 36–43% fewer moderate or severe exacerbations over 6 months when it was added to usual care (PubMed). It is not a rescue

💡TL;DR: Most of the time, the answer is no: a nebulizer without medicine will not treat your lungs; you are just inhaling moist air. The only common exception is sterile 0.9% saline, which can add moisture and thin mucus, but it does not open airways or stop an

💡TL;DR: Always keep your portable nebulizer and medications in your carry-on and pack at least a few extra days of doses for delays. Medically necessary liquids can exceed 3.4 oz (100 ml) when you declare them at security (TSA). Bring reliable power (spare batteries or a power bank)

💡TL;DR: Green phlegm usually means your immune system is actively fighting an infection; the color alone does not prove it’s bacterial or that you need antibiotics. Most cases improve with home care in 1–3 weeks; watch the timeline and how you feel. Seek care sooner if you

💡TL;DR: Most people with stable asthma, COPD, bronchiectasis, cystic fibrosis, or interstitial lung disease can travel safely with a simple plan. Airplane cabins are pressurized to about 6,000–8,000 feet, so bring rescue meds, hydrate, and ask your clinician about a fit‑to‑fly test or in‑

💡TL;DR: Mesh nebulizers create a fine 3–5 micron mist and, when used with good technique, deliver medication as effectively as jet units while being quieter and portable. To get the best results, sit upright, breathe slowly through a mouthpiece for lung treatments, finish the full dose (about 5–
