Respiratory Treatments

💡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: 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

💡TL;DR: Empyema is an infected pleural effusion (pus in the pleural space) that usually needs urgent drainage plus IV antibiotics, while a typical pleural effusion is extra fluid that is often not infected and is treated by fixing the cause and draining only if needed. Doctors look for loculations

💡TL;DR: A nebulizer can help COVID-related wheeze or chest tightness, especially if you have asthma or COPD, but it does not treat the virus. If you already have a prescription, keep using it as directed; if you do not, talk to your doctor before starting any nebulized medicine.

💡TL;DR: Pulmonary edema is fluid inside the lung’s air sacs; pleural effusion is fluid around the lungs in the pleural space. Edema tends to be sudden and is an emergency, treated in the hospital with oxygen and diuretics; effusions often build gradually and can be drained while the

💡TL;DR: ALS weakens the breathing muscles, not the lungs, so early clues are orthopnea, morning headaches, daytime sleepiness, and a weaker cough. Starting noninvasive ventilation at night when tests and symptoms change can improve sleep and daytime energy and is linked to longer survival. Airway clearance tools (assisted cough,

💡TL;DR: Most upper respiratory infections (URIs) are contagious because they are caused by viruses that spread easily through droplets and on your hands. You are usually most contagious in the first 2–3 days of symptoms and can spread infection for about 3–10 days overall. Stay home while

💡TL;DR: ALS gradually weakens the breathing muscles, so most people start with noninvasive ventilation (a BiPAP mask) when symptoms appear. A tracheostomy with a ventilator can extend life by a median of about 21 months after surgery, but it usually means 24/7 dependence on the machine and caregivers

💡TL;DR: Incentive spirometers are devices you slowly inhale through to exercise and reopen your lungs, while peak flow meters are devices you blow into to measure how fast air leaves your lungs. Use a peak flow meter mainly for day-to-day asthma or lung function monitoring, and an
