Abstract:
Objective To study effects of early non-invasive ventilation (NIV) application in treating elderly patients with acute left ventricular failure induced respiratory failure. Method Totally 32 elderly patients with acute left ventrieular failure induced respiratory failure, admitted from August 1997 to February 2007, received NIV treatment, and were retrospectively studied. There were 22 male and 10 female, aged (81.5?8.6) yearsdd. The changes of rahs, respiration rate, heart rate, arterial blood gas, cardiac function before and after NIV application were compared. According to the application time of NIV, 32 patients were divided into two groups: group A (early NIV application group, n=17) and group B (non-early NIV application group, n= 15). The time to improve the symptoms, the application time of NIV, cure rates, tracheal intubation rates and mortality were compared between the two groups. Results Thirty of the 32 patients survived, cardiac function was improved from New York classⅣtoⅠ～Ⅱ, respiratory rate, heart rate and blood pressure significantly decreased, PaO_2 and SaO_2 significantly increased and PaCO_2 significantly decreased. The tracheal intubation was performed in 4 patients. The time needed to improve the symptoms and the application time of NIV were significantly different between group A and group B (P
