Asthma

💡TL;DR: If you use a pressurized metered‑dose inhaler (pMDI), a spacer (valved holding chamber) makes each puff safer and more effective by getting more medicine to your lungs and less to your throat. Most spacers are low-cost (often $10–$40 USD) or available on prescription in some

💡TL;DR: Most nebulizer treatments take about 5–15 minutes, with many finishing near 10 minutes. Faster devices (vibrating mesh) and smaller volumes finish sooner; larger fills and older jet compressors can run longer. Medication matters: bronchodilators often run 5–10 minutes, while 4 mL hypertonic saline can take closer

💡TL;DR: For most coughs, start with sterile normal saline (0.9%) in your nebulizer; it hydrates airways and helps loosen mucus with minimal risk. For thick phlegm, hypertonic saline by TruNeb (3% or 7%) can thin secretions but may briefly increase coughing; ask your clinician if you have asthma

💡TL;DR: Asthma is not an autoimmune disease; it’s a chronic inflammatory airway condition where the immune system overreacts to external triggers (like pollen, dust, smoke, or cold air). In autoimmunity, the immune system attacks the body’s own tissues, which is not what happens in asthma. Treatments differ:

💡TL;DR: Yes — you can bring an asthma inhaler on a plane in both carry-on and checked bags; TSA classifies inhalers as medically necessary and exempts them from the 3-1-1 liquids rule. For a smooth trip, keep it in your carry-on for quick access and temperature

💡TL;DR: Hot cars can reach 140–160°F (60–71°C), far above safe storage for inhalers. Pressurized MDIs can weaken or even burst around ~120°F (49°C); all inhaler types work best at 68–77°F (20–25°C). If an inhaler overheats, treat it as unreliable

💡TL;DR: No — do not leave inhalers in a cold car. Most inhalers are designed for room temperature 59–86°F (15–30°C); at ≤32°F (0°C) the spray can be weak or fail. If it was briefly above freezing, let it warm to room temperature and release

💡TL;DR: Clean pressurized metered‑dose inhalers once a week: remove the metal canister, rinse the plastic mouthpiece under warm water for 30–60 seconds, and air‑dry completely before reassembly. Dry powder inhalers should not be rinsed; wipe the mouthpiece dry and keep the device closed between uses. Soft‑

💡TL;DR: Prime new metered-dose inhalers (MDIs) with 2–4 test sprays and re-prime after about 1–2 weeks of no use or if dropped so the first dose contains medication. Skipping priming can make the first puff mostly propellant with little or no medicine. Dry powder inhalers
