Abstract
PALENCIA-MOJICA, Clara Lizeth; VALERO-ORTIZ, Adriana Sofía and SILVA-RODRIGUEZ, Laura Jimena. Clinical and gasometric behavior in acute respiratory failure treated with a high-flow nasal cannula. Univ. Salud [online]. 2020, vol.22, n.2, pp.102-111. Epub Aug 01, 2020. ISSN 0124-7107. https://doi.org/10.22267/rus.202202.181.
Introduction:
High-flow nasal cannula offers an alternative treatment approach to conventional oxygen therapy in adults.
Objective:
To establish the clinical and gasometric behavior of patients with acute respiratory failure who live at 2,600 m.a.s.l. and are treated with high-flow nasal cannula in an adult intensive care unit.
Materials and methods:
Quasi-experimental pilot study with a pretest-posttest within-subject design and a sample size of 14 patients calculated through Epidat. A non-probabilistic convenience sampling was conducted for fourteen months.
Results:
78% of the patients were women and their average age was 68 years. Chronic Obstructive Pulmonary Disease (COPD) was diagnosed in 71.42% of the cases. An oxygen flow rate of 30 L/min was administered to patients with Chronic Obstructive Pulmonary Disease, while higher rates were used for the rest of the diagnoses. Nasal cannula treatment led to (i) a decreased respiratory function, (ii) a gradually improved arterial blood pressure in patients with hypoxemic failure, (iii) and a progressively increased oxygenation rate.
Conclusions:
High-flow nasal cannula is a useful therapeutic option in the management of patients with acute respiratory failure living at 2,600 m.a.s.l. because it improves oxygenation and reduces respiratory function.
