💡TL;DR: Hospital-grade nebulizers produce a fine, consistent mist (~3–5 microns) and finish most treatments in about 5–10 minutes. Modern mesh and compressor units for home can match clinic performance when used correctly, and many are FDA-cleared medical devices. Expect quieter operation and durable, cleanable parts that keep

💡TL;DR: Dry coughs don’t produce mucus; wet coughs do. Treat dry coughs by soothing irritation and, if needed, using a short‑term suppressant; treat wet coughs by thinning and clearing mucus with fluids, steam, and an expectorant. Most simple coughs clear in about 3 weeks (NHS), while a

💡TL;DR: Do not nebulize distilled water. It is not guaranteed sterile and its very low salt content can irritate your airways. Use sterile 0.9% saline or prescribed medications in unit-dose vials; use 3% to 7% hypertonic saline only if your clinician prescribes it. For cleaning, you may rinse

💡TL;DR: Yes. Smoking weed can damage your lungs. Cannabis smoke carries many of the same toxins as tobacco and irritates airways, causing cough, phlegm, and bronchitis; these symptoms often improve after quitting (CDC, American Lung Association). Tobacco causes far more proven long-term disease because people smoke it more often,

💡TL;DR: Airway inflammation means your breathing tubes are swollen and narrowed, often making extra mucus that causes cough, wheeze, and chest tightness. Most acute cases follow viral bronchitis, while chronic inflammation shows up in asthma and COPD; in asthma, 50–70% of patients have Type 2 (allergic) inflammation. The

💡TL;DR: Asthmatic bronchitis is a short-term chest infection on top of asthma, so you get the cough and mucus of bronchitis plus the wheeze and tight chest of an asthma flare. Most cases are viral and antibiotics are usually not needed. Expect about 2–3 weeks of symptoms, with

💡TL;DR: 70% SpO₂ is a medical emergency. Normal is 95–100% at sea level; anything below 80% is severe and can injure organs fast. At 70% you usually have minutes to a few hours without urgent treatment—call 911. Chronic lung disease does not make 70% “normal”; long‑term

💡TL;DR: Ipratropium bromide plus albuterol sulfate opens tight airways quickly for COPD and severe asthma flares. Most side effects are mild and short-lived (shaky hands, dry mouth, brief fast heartbeat), while serious symptoms are uncommon; seek care immediately for chest pain, swelling, or worse breathing right after a dose

💡TL;DR: Empyema = around the lung; lung abscess = inside the lung. Empyema usually needs drainage plus antibiotics; a lung abscess usually responds to antibiotics alone. CT is the best way to tell them apart; a classic study found CT correctly distinguished them in every case. Empyema carries higher short-term risk
