What Is a Portable Oxygen Concentrator and Who Needs One? A portable oxygen concentrator (POC) is a small, battery-powered medical device that pulls in room air, concentrates the oxygen, and sends it to you through a nasal cannula. Unlike oxygen tanks, POCs don’t store oxygen. They make it on

💡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 control, and bring a

💡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 (Diskus, Ellipta)

💡TL;DR: Yes—pneumonia can cause back pain when inflamed lung linings (pleurisy) make each deep breath or cough painful. The pain is usually sharp in the upper or mid‑back and occurs with cough, fever, and shortness of breath. About 1 million U.S. adults are hospitalized for pneumonia

💡TL;DR: Yes, you can vest during Pulmozyme to save time, and many CF clinics allow it; optimal: take Pulmozyme first and start airway clearance about 20–30 minutes later. A typical regimen is bronchodilator → hypertonic saline → Pulmozyme → airway clearance, with inhaled antibiotics last. Pulmozyme is usually 2.5 mg

💡TL;DR: Most MDIs keep spraying propellant even when the medicine is gone, so you can’t tell by sight, sound, taste, or shaking. Check a built‑in dose counter (zero means empty) or track your puffs: many rescue inhalers have 200 doses and many controllers have 120. Replace before
