Different diseases worldwide have repercussions at the level of multiple systems; but without a doubt a higher prevalence in the cardiopulmonary system. When a patient is hospitalized, he enters a continuous and often prolonged rest stay. Wherein, this physical inactivity plus its base pathology negatively impact its lung capacity. And low lung capacity has been shown to increase the risk of mortality, hospital stay, and complications. That said, the use of the device known as the "incentive inspirometer" is important, which to some extent there is no standardization of its use or applicability in a structured and planned manner. For this reason, the Japer method emerges as an idea; which, pretending through an exercise prescription through the incentive inspirometer according to 50% to 80% of the maximum inspiring capacity of the patient, improves their inspiring capacity. Having said this, the general objective was to analyze the effects of the JaPer method to improve lung capacity versus the traditional use of an inspirometer in hospitalized patients.

In 1974 the Respiratory Rehabilitation (RR) Committee of the American College of Chest Physicians defined RR as an art. It took almost 20 more years for another group of experts to describe it as a service. Moving forward in our reasoning, it is important to remember that all physical activity produces an increase in metabolic energy expenditure, as a result of body movement carried out in a specific period of time. The current literature through various organizations has been oriented to promote activities that arouse interest in generating movement and thus obtain benefits in improving health and quality of life. The respiratory physiotherapy techniques are basically divided into 2 types: facilitating techniques for expectoration and respiratory exercises. The former are indicated in hypersecretory processes, in alterations in the properties of mucus, ciliary dysfunction and alterations in the cough mechanism, to keep the airway free of secretions. The second is focused on improving a respiratory pattern, a respiratory reeducation, strengthening of respiratory muscles, preventing and / or reducing dyspnea and fatigue through the use of the inspirometer, respiratory exercises and specific techniques. In addition, it helps to decrease the hospital stay. Which, when prolonged, generates negative effects on the health system, such as: increased costs, poor accessibility to hospitalization services, saturation of emergencies and risks of adverse events. Plus all the negative effects it can generate in a hospitalized patient.

We don ́t have any plan because The research will be carried out directly among the researchers of our center. However, it is highlighted that we will make our results available to other researchers so that they can carry out future research that supports our results and compares with other types of populations.
