Any condition or injury that affects breathing can cause respiratory failure. The condition or injury may affect your airways or lungs. Or it may affect the muscles, nerves, and bones that help you breathe.

One of the most serious and common risks of being on a ventilator is pneumonia. The breathing tube makes it hard for you to cough. Coughing helps clear your airways of germs that can cause infections. The breathing tube that is put into your airway can allow bacteria to enter your lungs. As a result, you may develop pneumonia.

Ventilators are machines that blow air—or air with extra oxygen—into your airways and your lungs. Your airways are pipes that carry oxygen-rich air to your lungs when you breathe in. They also carry carbon dioxide (a waste gas) out of your lungs when you breathe out.

You may need a ventilator in an emergency if a condition makes it difficult to breathe on your own (called respiratory failure). You may also need a ventilator during surgery.

If you have been diagnosed with insomnia, follow your treatment plan and make healthy lifestyle and sleep changes. The following steps can help prevent your insomnia from returning or getting worse.

Lifestyle changes can often help improve short-term insomnia. A type of counseling called cognitive behavioral therapy for insomnia is usually the first treatment recommended for chronic insomnia. Several medicines can also help manage insomnia and help you have a regular sleep schedule. You may need to visit a doctor who specializes in treating sleep problems.

The main symptom of insomnia is trouble falling or staying asleep, even if you have enough time and the right conditions for good sleep. Over time, untreated insomnia may raise your risk of certain health problems or workplace or road accidents.

You may have a higher risk of insomnia because of your age, family history and genetics, environment or occupation (work), lifestyle, stress or worrying about sleep, or your sex.

Oímos muchos tipos de sonidos todos los días. Si bien muchos de esos sonidos son seguros, los sonidos que son demasiado fuertes y duran demasiado tiempo pueden dañar la audición de manera permanente. Mientras más alto sea el sonido, mayor será el daño a la audición y más rápido podría ocurrir el daño. Esto se llama pérdida de audición inducida por el ruido (noise-induced hearing loss, NIHL).
