💡TL;DR: Venturi masks deliver a fixed oxygen level, usually about 24% to 60%, by pairing each color-coded adapter with a set flow rate. Lower settings can create very high total flow, which helps keep FiO₂ steady even when breathing changes. This matters most when oxygen must be controlled carefully,

💡TL;DR: Most home pulse oximeters cost about $20 to $60, while FDA-cleared medical-grade options often run $150 or more. For quick home spot checks, a reputable fingertip model is usually enough, but readings can be thrown off by cold hands, motion, nail polish, and low blood flow. Most healthy

💡TL;DR: Acute bronchitis usually is not something you can cure overnight. Most people start to feel better within about 2 to 3 weeks, but the cough can last longer while the airways heal. Antibiotics usually do not help because most cases are caused by viruses, so the fastest path

💡TL;DR: Non-rebreather masks are usually set at 10 to 15 L/min and can deliver about 60% to 90% oxygen when the mask fits well and the reservoir bag stays partly inflated. They are short-term emergency devices for people who are still breathing on their own, not standard home

💡 TL;DR: Phlegm color can give clues, but it cannot diagnose an infection on its own. Clear or white mucus is often seen with normal irritation, allergies, or early viral illness, while yellow or green usually means your immune system is active, not that you automatically need antibiotics. Red, pink,

💡TL;DR: Pink frothy sputum usually means fluid is leaking into the lungs, and it often needs emergency care right away. It is most often linked to pulmonary edema from heart failure, but severe lung injury, pneumonia, or high altitude can also cause it. If it happens with shortness of

💡 TL;DR: White foamy mucus is often linked to mild causes like postnasal drip, allergies, reflux, or a short-term infection, and many cases improve with home care in 1 to 2 weeks. The big tradeoff is context: a small amount without breathing trouble is usually less urgent, but sudden shortness

💡TL;DR: Walking pneumonia is a milder form of pneumonia that often feels like a long‑lasting chest cold, with a nagging cough, tiredness, and chest discomfort that can stretch on for weeks. Fever may be low or even absent, so pay more attention to how long your cough and

💡TL;DR: Use your incentive spirometer often after surgery to keep your lungs open and clear. In the hospital, do about 10 slow breaths every hour while you’re awake; at home, do about 10 every 2 hours for the first week. Most people can stop after 1–2 weeks
