Intermittent positive pressure breathing (IPPB) is a respiratory therapy treatment for people who are hypoventilating. While not a preferred method due to cost, [ 1 ] IPPB is used to expand the lungs, deliver aerosol medications, and in some circumstances ventilate the patient.
The administration of positive pressure ventilation, either mechanical ventilation or non-invasive ventilation, can result in barotrauma (pressure-related injury) leading to a pneumothorax. [ 13 ] Divers who breathe from an underwater apparatus are supplied with breathing gas at ambient pressure , which results in their lungs containing gas at ...
For example, positive pressure ventilation was used to stabilize the flail segment from within the chest. [ 15 ] [ 39 ] It was first proposed in 1965 that this respiratory insufficiency is most often due to injury of the lung rather than to the chest wall, [ 20 ] and a group led by J.K. Trinkle confirmed this hypothesis in 1975. [ 38 ]
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
During positive pressure ventilation, atelectatic regions will inflate, however, the alveoli will be unstable and will collapse during the expiratory phase of the breath (atelectotrauma). This repeated alveolar collapse and expansion (RACE) is thought to cause VALI. By opening the lung and keeping the lung open RACE (and VALI) is reduced. [7]
Severe exacerbations can require hospital care where treatments such as oxygen and mechanical ventilation may be required. [22] Mechanical ventilation can be invasive (endotracheal intubation) or non-invasive forms of ventilation such as continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BiPAP).

High-frequency jet ventilation (HFJV) minimizes movement of the thorax and abdomen and facilitates surgical procedures where even slight motion from spontaneous or intermittent positive pressure ventilation may significantly affect the duration and success of the procedure (for example atrial fibrillation ablation).
Since mechanical ventilation can worsen a pneumothorax, it can force air into the tissues; when subcutaneous emphysema occurs in a ventilated patient, it is an indication that the ventilation may have caused a pneumothorax. [2] It is not unusual for subcutaneous emphysema to result from positive pressure ventilation. [25]
