Lung resection, the main therapy in lung cancer, is associated with complications which may be mitigated by non-invasive mechanical ventilation (NIMV). Current paper investigates the effects of NIMV associated with conventional physiotherapy in patients with lung resection due to cancer. Patients with lung cancer who had undergone lobectomy, bilobectomy or pneumonectomy were included. During the post-surgery period they were evaluated and the expirometric variables, maximum respiratory pressure (PImax and PEmax) and respiratory flux peak (PFE); they practiced conventional physiotherapy and NIMV (during two hours), of the immediate post-surgery (POi) to the second PO, totaling five sessions. Average arterial pressure and heart frequency at minutes 0, 5º, 10º, 15º, 30º, 45º, 90º and 120º were measured after the start of protocol. PImax, PEmax, PFE and ventilometry were gauged in all treatment days. They were reevaluated on the fifth PO. Twelve patients with mean age 58.91±9.52 years were included. There were statistical differences between CVF and VEF1, with lower rates from the pre-operatory to the post-operatory. There was also a significant decrease in PImax, PEmax and PFE from the pre-operatory to the immediate PO with a return to previous rates of PImax and PEmax in PO5. Rate variations within normality were reported in the analysis of hemodynamic variables during NIMV. Results show that NIMV in the resection post-surgery phase due to cancer may be an auxiliary resource with a good evolution in the patients´ treatment without any important hemodynamic changes.
