Antecedentes: La saturación periférica de oxígeno es un método no invasivo que refleja el estado oxigenatorio de una persona, sin embargo no ha sido estudiada ampliamente en la población adulta en la altura que se presenta en la consulta externa con enfermedades de las vías respiratorias superiores e inferiores. Objetivo: Evaluar la utilidad de la pulso oximetría como discriminador entre enfermedades de la vía aérea superior versus inferior. Material y métodos: Se analizó 7848 pacientes de 18 a 65 años con enfermedades respiratorias altas y bajas y pacientes que acudieron para exámenes generales que contaran con registros de signos vitales, pulso oximetría y antropometría atendidos en la consulta externa en la altura (2750m). Para el análisis de medias se usó el test de T de Student y análisis ANOVA en caso existan tres grupos de variables. Se realizó el análisis ROC...

INTRODUCCIÓN: There is a lack of population studies regarding factors that impact hemoglobin levels in children of a country with varying altitudes of residence.

Background: At sea level, tachypnea (respiratory rate> 24 / min) is a factor commonly associated with community-acquired pneumonia. However, in high altitudes, it must achieve higher rates, thus there is a need to look for other early predictors at these settings. Objective: This study aims to explore the presence of hypoxemia associated to the presence of diseases of the lower airways or not according to pulse oximetry readings. Methods: We used a database of 205071 18 to 65 year old altitude-resident outpatient adults in Cajamarca, Peru (2750 masl) as part of a private health program. Data was collected corresponding to demographic characteristics, vital functions (including peripheral oxygen saturation, SpO2) and individual diagnosis according to ICD-10 classification. The patients were divided into two groups according to the SpO2 level of 90% detected through a portable pulse oximet...

Background: According to the World Health Organization, tuberculosis produces around 1.5 million deaths worldwide each year. In Peru, during the 2011-2015 period, incidence and morbidity rates have decreased from 97.4 to 87.4 and from 109.7 to 99.5 respectively. However, tuberculosis remains as the fifteenth cause of death. The clinical evolution of these patients will depend on many factors, such as adherence to treatment, comorbidities, drug resistance of the pathogen. Therefore, it is the presence and interaction of these factors that help us predict which patients could potentially fail during the treatment. Objective: To determine in patients with pulmonary tuberculosis whether direct smear study at the beginning of treatment is a prognostic factor of the discharge condition. Methods: We performed a secondary analysis of the database of the retrospective cohort study "Evaluation of ...
