Which condition poses a contraindication for intermitted positive pressure breathing (IPPB)?

• A. Fractured ribs
• B. Pulmonary edema
• C. Untreated pneumothorax
• D. A patient requiring bronchodilation AND lung expansion

Answer: (C)

The contraindication for intermittent positive pressure breathing (IPPB) in the context provided is untreated pneumothorax. This condition occurs when air leaks into the pleural space, leading to a collapse of the lung. When implementing IPPB, positive pressure is applied during inhalation to assist with lung expansion. However, in a patient with an untreated pneumothorax, the external pressure could worsen the situation by further collapsing the lung, potentially leading to respiratory distress or failure. In contrast, fractured ribs can allow for the use of IPPB with caution; it may help in lung expansion despite the pain from broken ribs. Pulmonary edema, although a serious condition, may not necessarily contraindicate the use of IPPB; in fact, it can sometimes be beneficial in managing fluid overload. A patient requiring bronchodilation and lung expansion does not pose a contraindication, as IPPB can be used to achieve both purposes, provided that no other complications, like an untreated pneumothorax, are present.
