Medical Ventilator Complications
Complications of Mechanical Ventilation. Perhaps most feared among medical complications occurring during mechanical ventilation are pneumothorax bronchopleural fistula and the development of nosocomial pneumonia.

Complications associated with mechanical ventilation are primarily related to the use of positive pressure applied to the lungs and the artificial airways required to provide invasive ventilation.
Medical ventilator complications. The act of ventilating somebody is a perverse thing to do as it is a positive pressure process in contrast to the normally negative pressure process of breathing. Instead of taking a transport ventilator and adding ICU features Hamilton Medical designed a fully equipped ICU ventilator and made it shock resistant water-protected and light-weight. The process of distending somebodys lungs with positive pressure may also give rise to ventilator-associated lung injury.
The two main issues that a ventilated patient may experience are an infection referred to as ventilator-associated pneumonia VAP which can occur if the breathing tube allows bacteria into the airways and lung damage in which the air being forced into the lungs causes damage to the organs tissue known as ventilator-associated lung injury VALI. In the final phase of the development a close. Too much oxygen can also damage your lungs.
The breathing tube can let germs into your lungs. Ventilator-induced lung injury such as barotraumas due to over-distension of alveoli leading to. The fall in functional residual capacity promotes airway closure and atelectasis formation.
Fall in cardiac output due to positive pressure in lung and thorax that reduces venous return. The most common complications include arrhythmias myocardial ischemia usually a type II or demand nonST-segment elevation myocardial infarction although primary acute coronary syndrome ST-segment elevation myocardial infarction may also occur as most. Babies put on a ventilator especially premature infants may be at a higher risk of lung damage from excess oxygen therapy and lung infections in childhood and adulthood.
Complications of Mechanical Ventilation Barotrauma. Cardiovascular complications are associated with critical illness and mechanical ventilation but are rarely a direct complication. This narrative review presents the impact of obesity on the respiratory system and the key points to optimize airway management noninvasive and.
Oxygen toxicity refers to inflammatory changes alveolar infiltration and eventually pulmonary fibrosis that can develop following prolonged exposure to high FIO2 eg 06. This can raise the risk of getting pneumonia. Air and supplemental oxygen is forced into the lungs through a ventilator.
Volutrauma is a condition in which the alveoli become filled with fluid and is usually caused by mechanical. The complications most commonly encountered in the ED include hypoxia hypotension high-pressure alarms and low exhaledvolume alarms. Using a ventilator decreases the work your diaphragm and other breathing muscles have to do so they can become weak.
Medical ventilators are also used when a person has a condition that prevents effective breathing. Various conditions can cause breathing difficulties including respiratory illnesses head injuries cardiac conditions and drug overdoses. Obesity is an important risk factor for major complications morbidity and mortality related to intubation procedures and ventilation in the intensive care unit ICU.
The main risk of using a ventilator is infection. Hamilton Medical a Swiss company that is specialized in critical care ventilators had used a rather different approach when designing the ventilator. Barotrauma is a condition in which the alveoli tiny air sacs in the lungs rupture or burst due to high.
A common complication of prolonged stays in intensive care units is something called ICU delirium in which patients become severely confused. Complications of Mechanical Ventilation- I- Airway Complications II- Mechanical complications III- Physiological Complications IV- Artificial Airway Complications. Positive pressure not only damages sensitive lung tissue but also may inhibit blood flow returning to the heart.
These entities may owe as. This may lead to some problems and. Sinus infections are also common if you have a.
I- Airway Complications 1- Aspiration 2- Decreased clearance of secretions 3- Nosocomial or ventilator-acquired pneumonia 124 125. Tube in one lung causes a collapse of the other lung. Failure of the ventilator to cycle of safety alarms to function properly and of inspired gas to be properly heated or humidified are examples of equipment-related complications.
