Value analysis of adjuvant treatment of noninvasive ventilator on elderly patients with acute respiratory failure

Abstract

Objective To investigate the effect of noninvasive ventilator auxiliary treatment on elderly patients with acute respiratory failure. Methods Forty-one elderly patients with acute respiratory failure underwent noninvasive ventilator assisted ventilation therapy were selected. All of the patients were given noninvasive ventilator assisted ventilation therapy on the basis of conventional drug treatment. The therapeutic effects of noninvasive ventilator assisted ventilation, arterial blood gas indexes before and after treatment and complications were observed. Results After noninvasive ventilator assisted ventilation treatment, the clinical symptoms and signs improved, no patients died. The clinical effective rate of noninvasive ventilator assisted ventilation was 100%; nine patients occurred complications such as abdominal distension, aspiration, swelling and pain, the incidence of complications was 21.95%, no severe complications occurred. Before treatment, the pH, PaO2 and PaCO2 respectively was (7.20±0.05), (41.8±5.9) mmHg and (81.8±7.8) mmHg(1 mmHg=0.133 kPa), which was (7.41±0.04), (96.3±6.6) mmHg and (44.3±8.2) mmHg after treatment, there were significant differences(t= 5.414, 6.643, 7.445, P<0.01). Conclusions Noninvasive ventilator assisted ventilation therapy on the basis of conventional drug treatment for elderly patients with acute respiratory failure, can obviously improve the patient's clinical symptoms and arterial blood gas indexes.
