Pneumothorax is another possible problem that must be detected during positive pressure ventilation (PPV)and treated quickly.Pneumothorax can be recognized as increased WOB if a patient is conscious.For example,the patient may demonstrate nasal flaring,use of accessory muscles,uneven chest wall movement,and absence of breath sounds on the affected side.Auscultation and percussion of the chest,cardiovascular assessment,and ventilating pressure evaluations usually can distinguish a pneumothorax from other problems.
