Cómo funciona el sueño - Por qué es importante dormir

El sueño juega un papel vital en la buena salud y el bienestar a lo largo de su vida. La forma en que se siente mientras está despierto depende en parte de lo que sucede mientras duerme. Durante el sueño, su cuerpo está trabajando para mantener una función cerebral saludable y conservar su salud física. En niños y adolescentes, el sueño también ayuda a apoyar el crecimiento y el desarrollo. Con el tiempo, dormir de manera inadecuada puede aumentar su riesgo de tener problemas de salud crónicos. También puede afectar qué tan bien piensa, reacciona, trabaja, aprende y se lleva bien con los demás. Aprenda cómo el sueño afecta el corazón y el sistema circulatorio, el metabolismo, el sistema respiratorio, el sistema inmunitario y cuánto sueño es suficiente.

Cómo funciona el sueño - Fases y etapas del sueño

Cuando duerme, pasa por dos fases del sueño: el movimiento ocular rápido (MOR) y el sueño de no movimiento ocular rápido (NMOR). El ciclo comienza cada 80 o hasta 100 minutos. Por lo general, hay de cuatro a seis ciclos por noche. Puede despertarse brevemente entre ciclos. Los estudios del sueño utilizan sensores para registrar los movimientos oculares y la actividad cerebral, que se utilizan para clasificar las fases y etapas del sueño.

Cómo funciona el sueño - Su ciclo de sueño o vigilia

Existen muchos factores que juegan un papel en la preparación de su cuerpo para conciliar el sueño y despertarse. Su cuerpo tiene varios relojes internos, llamados relojes circadianos. En general, estos relojes siguen un ritmo repetitivo de 24 horas, llamado ritmo circadiano. Este ritmo afecta a cada célula, tejido y órgano de su cuerpo y cómo funcionan.

Respiratory Failure – Living With

Respiratory failure  acute respiratory failure  chronic respiratory failure  hypoxemic respiratory failure  hypercapnic respiratory failure  ventilator  CPAP  Extracorporeal membrane oxygenation (ECMO) 

For both acute (short-term) and chronic (long-term) respiratory failure, it is important to follow your treatment plan, manage your condition, and know when you should seek medical care. You may need pulmonary rehabilitation to help your lungs work better. Your oxygen and carbon dioxide levels may take a while to return to a healthy range. Because of this, you may continue to have shortness of breath or other symptoms for a few weeks or longer. You may need to do daily activities more slowly.

Respiratory Failure – Treatment

Acute respiratory failure can be life-threatening and may need a quick diagnosis and emergency medical treatment in a hospital. Emergency treatment can help quickly improve your breathing and provide oxygen to your body to help prevent organ damage. Your healthcare team will then treat the cause of your respiratory failure. Treatments for respiratory failure may include oxygen therapy, medicines, and procedures to help your lungs rest and heal.

Respiratory Failure – Signs, Symptoms, and Complications

Symptoms of respiratory failure depend on its cause, the levels of oxygen and carbon dioxide in your blood, and whether respiratory failure developed slowly over time or suddenly. You may start out with mild symptoms such as shortness of breath or rapid breathing, which may get worse over time. Acute respiratory failure can be a life-threatening emergency. Respiratory failure may cause damage to your lungs and other organs, so it is important to get treated quickly.

If you have a condition that puts you at risk of respiratory failure, talk to your doctor. He or she can ask questions and do a physical exam to look for issues that may put you at risk of getting respiratory failure in the future. Your doctor can also talk to you about how to manage your condition to prevent respiratory failure. He or she can also screen you if you have a planned surgery.
