Volutrauma is the term that describes ultrastructural lung injury due to overdistention occurring during mechanical ventilation. The two terms—barotrauma and volutrauma—reflect the two sides of the same phenomenon: the lung injury due to a large distending volume and/or to a high airway pressure (10-19).

Is barotrauma the same as Volutrauma?
Volutrauma is the term that describes ultrastructural lung injury due to overdistention occurring during mechanical ventilation. The two terms—barotrauma and volutrauma—reflect the two sides of the same phenomenon: the lung injury due to a large distending volume and/or to a high airway pressure (10-19).
How does barotrauma cause a pneumothorax?
Pulmonary barotrauma from invasive mechanical ventilation refers to alveolar rupture due to elevated transalveolar pressure (the alveolar pressure minus the pressure in the adjacent interstitial space); air leaks into extra-alveolar tissue resulting in conditions including pneumothorax, pneumomediastinum.
What causes barotrauma in the lungs?
Barotrauma is a condition in which the alveoli (air sacs of the lungs) rupture with a subsequent entry of air into the surrounding extra alveolar space. Barotrauma is typically caused by lung air sacs rupturing or a direct injury.
What is an example of barotrauma?
Barotrauma typically occurs when the organism is exposed to a significant change in ambient pressure, such as when a scuba diver, a free-diver or an airplane passenger ascends or descends or during uncontrolled decompression of a pressure vessel such as a diving chamber or pressurised aircraft, but can also be caused …
What is Volutrauma ventilation?
Volutrauma refers to the local overdistention of normal alveoli. Volutrauma has gained recognition over the last 2 decades and is the impetus for the lung protection ventilation with lower tidal volumes of 6–8 mL/kg. Computed tomography scans have demonstrated that ARDS has a heterogeneous pattern of lung involvement.
How does positive pressure cause pneumothorax?
Positive pressure ventilation can exacerbate air leaks and prevent pleural healing, potentially causing a rapid increase in the size and severity of existing pneumothorax. An algorithmic approach to treatment of pneumothorax related to mechanical ventilation.
What are signs of barotrauma?
The most common symptoms of ear barotrauma may include:
- Feeling of pressure in the ear.
- Ear pain.
- Dizziness.
- Feeling like you have a blocked ear.
- Bleeding from the ears or into the middle ear.
- Ringing in your ears.
- Hearing loss.
How is barotrauma treated?
Ear Barotrauma Treatment Sometimes you may need surgery to repair the eardrum or the opening into your middle ear. For a mild case, you can usually treat your symptoms yourself. Try to “pop” your ears. Chew gum or hard candy.
How is lung barotrauma treated?
No specific treatment is required for pneumomediastinum; symptoms usually resolve spontaneously within hours to days. After a few hours of observation, most patients can be treated as outpatients; high-flow 100% oxygen is recommended to hasten resorption of extra-alveolar gas in these patients.
What is the treatment for barotrauma?
You might need medicines for your ear barotrauma. These might include: Nasal steroids and decongestants, to reduce congestion around the eustachian tube opening. Antibiotics, if an infection develops.
How do you treat barotrauma?
Keep the ear dry.
- Initial treatment involves oral decongestants and nasal spray to help open the eustachian tube.
- Pain medications are helpful, and eardrops to relieve pain may be used if the eardrum is not ruptured.
- A ruptured eardrum will need antibiotics by mouth to prevent infections.
Can you heal from barotrauma?
You may not need any treatment if you get ear barotrauma. Most injuries heal on their own with time, and most people’s symptoms will go away. But your eardrum might not heal normally if a blast caused the injury. You might need medicines for your ear barotrauma.
