Synchronized Intermittent Mandatory Ventilation With and Without Pressure Support Ventilation in Weaning Patients With COPD From Mechanical Ventilation: Results
Ten patients were randomized to receive SIMV/ PSV (group 1) and nine were randomized to receive SIMV alone (group 2). The clinical and physical characteristics of the 19 studied patients are given in Table 1. Group 1 and group 2 patients were all cigarette smokers with obstructive lung disease documented by their pulmonary function test […]
Synchronized Intermittent Mandatory Ventilation With and Without Pressure Support Ventilation in Weaning Patients With COPD From Mechanical Ventilation: Measurements
At each step of SIMV rate (te, at each 2 cycles/min decrease), several measurements were performed when a ventilatory steady state was achieved on semirecumbent position: average systolic blood pressure (SBP) and heart rate (HR) from repeated measurements, spontaneous tidal volume (sVt), total and spontaneous minute ventilation (Ve and sVe). The steady state was arbitrarily […]
Synchronized Intermittent Mandatory Ventilation With and Without Pressure Support Ventilation in Weaning Patients With COPD From Mechanical Ventilation: Patients
This prospective study was designed for male COPD patients, intubated and mechanically ventilated because of an acute exacerbation of their disease. All patients exhibited clinically a chronic bronchitis defined as a productive cough with sputum production for 3 months per year for a 2-consecutive-year period (American Lung Association criteria and an irreversible chronic airflow limitation […]
Synchronized Intermittent Mandatory Ventilation With and Without Pressure Support Ventilation in Weaning Patients With COPD From Mechanical Ventilation
The most critical time for patients with chronic obstructive pulmonary disease (COPD) mechanically ventilated for acute respiratory failure (ARF) is the weaning period. Asthma inhalers online Link Patients with hyperinflation and/or bad nutritional status2 are obviously exposed to difficulties in recovering sustained spontaneous breathing. Indeed, patients with COPD often do not tolerate discontinuation of mechanical […]
Persistence of Airway Obstruction and Hyperresponsiveness in Subjects With Asthma Remission: Comment
Medication may influence symptoms and airway responsiveness. It has been shown that prolonged use of inhaled steroids may reduce airway responsiveness and “induce” remission in some subjects. In our study, only two subjects “in remission” previously took inhaled steroids or prednisone, most subjects using a /82-agonist on demand, in some of them in association with […]
Persistence of Airway Obstruction and Hyperresponsiveness in Subjects With Asthma Remission: Conclusion
More than 50 percent of subjects with mild increases in airway response to histamine denied symptoms suggestive of asthma. This is similar to what has been reported by Woolcock et al28 showing that 32 percent of adults with airway hyperresponsiveness never had symptoms suggestive of asthma. This suggests that for a similar degree of airway […]
Persistence of Airway Obstruction and Hyperresponsiveness in Subjects With Asthma Remission: Discussion
In our study, asthma remission occurred between ages 11 and 20 years in most subjects but remissions were also observed after the age of 40 years. Remissions in asthmatic children have been well studied but little is known, however, of asthma remissions in adults. Spontaneous remissions of asthma have been reported to occur in 30 […]
