At home, you may check your lungs functioning with an instrument named "Peak Flow meter". It is a small hand held device, when you blow air into it, it calculates the lung capacity and expansion. Spirometer is another instrument which helps in similar way in lung assessment and additionally it also has therapeutic usage. You may check oxygenation level by "Pulse Oximeter" which gives indirect clue on lung damage but keep in mind there are other medical conditions which may affect pulse oximeter readings.

To check your lungs at home, you can pay attention to your breathing and any symptoms you might notice. Here are some simple ways to monitor your lung health:

Observe your breathing: Notice if you have any shortness of breath, wheezing, or persistent cough.
Check your breathing rate: Count how many breaths you take in one minute. Normal resting breathing rate is about 12-20 breaths per minute.
Try deep breathing: Take a deep breath and see if you can do it comfortably without pain or tightness.
Listen for unusual sounds: If you have a stethoscope, you can listen for wheezing or crackling sounds, but this is optional.

If you experience symptoms like persistent cough, chest pain, difficulty breathing, or coughing up blood, it is important to see a healthcare professional for proper evaluation and tests like chest X-rays or spirometry. Home checks are helpful for awareness but cannot replace medical assessment when needed.

I've just finished a round of clarithromycin but still have this chesty, wet, persistent cough. I went back and got prescribed azithromycin for 4 days, and it seemed to helpI felt much better. But now, just two days after finishing the meds, the cough is back. Could this be just my lungs clearing stuff out? I'm also feeling really congested in my nose again. What could be going on?

kk it's normal

I'm really worried because my mom has been using Foracort 400 and Tiova inhalers twice daily for about ten years now, but today she accidentally took Tiova twice instead of once. I'm not sure if she should still take her Foracort as planned or skip it. What should we do?

If your mom has accidentally taken Tiova twice, it's important not to take another dose of Tiova today. She can still take her usual Foracort dose, as long as she hasn't exceeded the recommended limit for either inhaler. If she feels any unusual symptoms like increased heart rate or dizziness, please seek medical advice promptly.
