For the study of this clinical case, information has been collected during the period in which the pre-professional practices were carried out in which, a 62-year-old patient was admitted to the health home by emergency presenting a clinical picture of respiratory failure. According to the information in the medical history, it was observed that the patient has suffered from chronic obstructive pulmonary disease (COPD) and pulmonary fibrosis for 8 years. Due to the pathologies mentioned two years ago, a tracheostomy was performed to counteract the respiratory problem and prolong the patient's life. Knowing these antecedents, the diagnosis of COPD and exacerbated pulmonary fibrosis is reached, then all the medical personnel conclude that it is a critical patient since 2 years ago a colostomy was also performed due to digestive problems. In order to improve the patient's health at the time of emergency, many studies are carried out, nebulisations with long-term bronchodilators are performed and in 24 hours he is transferred to the intensive care unit (ICU) where he is it is connected by mechanical ventilation. As the days go by, the respiratory situation worsens presenting pneumonia. Also, the patient becomes hemodynamically destabilized after a surgery performed with the purpose of closing the colostomy. All the procedures carried out and mentioned above concurred with the purpose of improving the health of the patient but, due to the different complications and pathological antecedents, the objective was not achieved, which causes the patient to suffer a cardiorespiratory arrest causing death.For the study of this clinical case, information has been collected during the period in which the pre-professional practices were carried out in which, a 62-year-old patient was admitted to the health home by emergency presenting a clinical picture of respiratory failure.

Según la información de la historia clínica se pudo apreciar que el paciente desde hace 8 años atrás padece de enfermedad pulmonar obstructiva crónica (EPOC) y fibrosis pulmonar. Por las mencionadas patologías hace dos años, se le ha realizado una traqueostomia para contrarrestar el problema respiratorio y prolongar la vida del paciente. Conociendo dichos antecedentes se llega al diagnóstico de una EPOC y fibrosis pulmonar reagudizada entonces, todo el personal médico concluye de que se trata de un paciente critico ya que hace 2 años también se le realiza una colostomía por problemas digestivos. Con la finalidad de mejorar la salud del paciente en el momento que llega a emergencia se le realiza muchos estudios, se le realiza nebulizaciones con broncodilatadores de larga duración y en 24 horas se lo traslada a la unidad de cuidados intensivos (UCI) en donde se lo conecta a ventilación mecánica. Con el pasar de los días, la situación a nivel respiratorio empeora presentando neumonía. También, el paciente se desestabiliza hemodinamicamente posterior a una cirugía que se le realiza con el propósito de cerrar la colostomía. Todos los procedimientos realizados y mencionados anteriormente concurrieron con el propósito de mejorar la salud del paciente pero, por las diferentes complicaciones y antecedentes patológicos no se logra el objetivo lo que ocasiona que el paciente sufra un paro cardiorrespiratorio causándole la muerte.
