Is CPAP treatment not effective after supratentorial craniotomy?

We read with great interest the study by Sah et al. [1] regarding the efficacy of continuous positive airway pressure (CPAP) and incentive spirometry on respiratory functions during the postoperative period following supratentorial craniotomy. In this prospective, randomized, placebo controlled study, they compared the effects of incentive spirometry (IS), CPAP and 4L/min O2 inspiration (Control group) on forced vital capacity (FVC) and other pulmonary function tests of and arterial blood gases of patients who were followed up in intensive care unit after supratentorial craniotomy.
