The role of non-invasive ventilation in the treatment of COPD

If you have chronic obstructive pulmonary disease (COPD), you may have trouble breathing properly. When you breathe in, your lungs may not absorb enough oxygen (O2), and when you breathe out, you may have trouble getting rid of the waste gas, carbon dioxide (CO2).

If you were in hospital, your doctor may have prescribed ventilation. This is to help your lungs exchange oxygen and carbon dioxide more efficiently. Your doctor may also decide that you need to keep on using ventilation at home if you have:

  • Breathlessness
  • Daytime sleepiness
  • Low levels of oxygen or high levels of carbon dioxide in your blood.

The most preferred type of ven

tilation in hospital and at home is non-invasive ventilation.

With non-invasive ventilation, you wear a mask that is attached via an air tube to a portable ventilator.You may be prescribed ventilation for use during sleep and during the day.

Benefits of non-invasive ventilation

Non-invasive ventilation provides a number of benefits for certain COPD patients.

In the hospital, it can help by:

Speeding recovery

Reducing complications

Reducing costs

Enabling you to go home sooner.1

At home, it can help by:

Reducing breathlessness

Lowering the risk of hospital readmission

Improving your quality of life and survival. 2,3,4


Your doctor can advise whether home non-invasive ventilation is suitable for you.

Sleep Revitalizes your Mind, Body, & Heart

The body goes under many transformations, while it is in the state of rest during sleep. There are many essential functions that take place in the body such as tissue repair, memory and energy restoration, release of essential hormones, muscle relaxation, and others. While you are asleep, the brain releases indispensable hormones that promote tissue growth. This process helps your body rejuvenate from the daily hustle bustle. Moreover, tissue growth aids in the recovery from wounds or cuts. Sunita Kumar, Co-Director, Centre for Sleep Disorders, Loyola University Medical Centre, aptly remarks that during sleep the body produces more white blood cells, to fight countless bacteria and viruses1. The heart rate also registers a dip during sleep, which according to Ms. Kumar, strengthens the heart as it is at rest with lowered activity. Moreover, a good night’s sleep also reduces the chances of getting afflicted with heart diseases.

Good Sleep = Sharp Memory

Sleep is a time, when becomes sharp and strong. Sleep quantity and quality play a fundamental role in determining what one remembers and what one doesnt. Therefore, development of long-term memory (LTM) from short-term memory (STM) happens during sleep.  Scientific researches state that the brain follows a different mechanism for storing memories through the hippocampus and neo-cortex areas. Hippocampus helps you to remember your life experiences (childhood memories), while the neo-cortex is responsible for remembering the concepts you learn (name of a color). Communications and sync between the two, helps in learning new data and updating old ones.

Sleep Steers Hormonal Hunger

Sleep not only affects your energy levels and mental functions, but also regulates your body weight. Improper sleep is related to the increasing cases of obesity, worldwide2. Many hormones which regulate the feeling of hunger (ghrelin) and signal the feeling of being full (leptin), are all influenced by the quality of your sleep.  Leptin: This is also known as satiety hormone, which is produced by the fat cells of the body. It prevents overeating by sending signals to the brain that the body does not require more food, as there is enough to fuel the body.  Ghrelin: This hunger hormone is produced in the gastrointestinal tract, which signifies the body that there is need for food. This hormone rises in the body, when you feel hungry and decreases when you have consumed some food.  Studies show that people who have disrupted patterns of sleep - have larger appetite, because of higher ghrelin secretion and lowered secretion of leptin. This imbalance in the secretion of these hormones is a result of improper sleep patterns3.
