![]() In other cases, the outcome may be less favorable. Some may come off the ventilator, recover, and go home. The outlook for people with COPD on a ventilator may vary. However, the duration of ventilation will depend on the severity of COPD. Research from 2018 involving 670 people with severe COPD requiring mechanical ventilation for acute respiratory failure found that the median duration of ventilation was 3 days. In some cases, a person may not be able to live without a ventilator. Some may only need ventilation for a few hours or days, while others may need much longer. Doctors also may prescribe noninvasive ventilation for home use.Ī 2021 study found that people who received noninvasive ventilation at home experienced a significant reduction in emergency room visits and hospitalizations compared with those who did not.Īccording to the American Thoracic Society, healthcare professionals aim to help people stop using a ventilator as soon as possible. Practitioners often try noninvasive ventilation first before invasive. Instead, people receive breathing support through a nasal mask or face mask. In noninvasive ventilation, also known as noninvasive positive pressure ventilation, doctors do not use an endotracheal tube. However, a doctor usually reserves invasive mechanical ventilation for intensive care units or the operating room. Doctors typically insert this through a surgical incision in the trachea. ![]() If a person requires a ventilator for an extended period or the tube cannot pass through the oropharynx, they may insert a tracheostomy tube. A practitioner will insert this through a person’s mouth or nose into their trachea. Invasive mechanical ventilation typically involves the insertion of an endotracheal tube. There are two main types: Invasive ventilation They also hold a constant amount of low pressure, or positive end-expiratory pressure, which stops the air sacs in the lungs from collapsing. Ventilators deliver a mixture of oxygen and air into a person’s lungs to help oxygen get into the body. The goal of mechanical ventilation for people with COPD is to improve gas exchange, decrease the work of breathing, and rest the muscles involved. With mechanical ventilation, the machine takes over the work of breathing. Someone with COPD may also require a ventilator due to complications from a co-existing medical condition or certain surgical interventions. People with high CO2 levels may also experience respiratory acidosis, which results in high levels of acid in the blood. When CO2 levels build, a person may experience hypercapnia, where there is too much CO2 in the blood. High carbon dioxide levelsĪlternatively, some people with COPD may develop respiratory failure due to high CO2 levels. People with low oxygen levels may also develop hypoxemia, which is a condition involving low oxygen levels in the blood. This means the lungs cannot provide sufficient amounts of oxygen for the tissues in the body to function. If these levels become too low, hypoxia develops. When an individual with COPD cannot get enough air into their lungs, they may develop respiratory failure due to the inability to maintain typical oxygen levels. This may lead to respiratory failure as CO2 levels climb and oxygen levels fall due to insufficient breathing. ![]() The diaphragm, which plays a role in breathing, may also not work as efficiently in people with the condition.Ī person with COPD who is having difficulty breathing may eventually become tired. ![]() People with COPD may have lungs that must work hard to inhale oxygen and exhale carbon dioxide (CO2). “Acute” means sudden, as opposed to “chronic,” which means long-term. Sudden worsening of COPD is the third most common reason people become hospitalized due to acute respiratory failure. The main reason someone with COPD may need a ventilator is due to respiratory failure. Share on Pinterest Rachel Wisniewski/The Washington Post/Getty Images ![]()
