A controlled trial of intermittent positive pressure breathing, incentive spirometry, and deep breathing exercises in preventing pulmonary complications after abdominal surgery.

Controversy exists regarding the routine use of aids to lung expansion in the prevention of pulmonary complications after abdominal surgery. We prospectively randomized 172 patients into 1 of 4 groups: the control group (44 patients) received no respiratory treatment, the IPPB group (45 patients) received intermittent positive pressure breathing therapy for 15 min 4 times daily, the IS group (42 patients) was treated with incentive spirometry 4 times daily, and the DBE group (41 patients) carried out deep breathing exercises under supervision for 15 min 4 times daily. Roentgenographic changes, observed 24 h after surgery, were comparable in the 4 groups (20.5 to 36.6%). Pulmonary complications were defined as the development of 3 or more of 6 new findings: cough, phlegm, dyspnea, chest pain, temperature greater than 38 degrees C, pulse rate more than 100 beats/min. The frequency of development of pulmonary complications was 48% in the control group, 22% in the IPPB group (p less than 0.05), 21% in the IS group (p less than 0.05), and 22% in the DBE group (p less than 0.05). Side effects of respiratory treatment were observed only in the IPPB group (18%; p less than 0.05). Hospital stay in patients undergoing upper abdominal surgery was significantly shorter in the IS group (mean +/- SD, 8.6 +/- 3 days) than in the control group (13 +/- 5 days). This difference was not observed for the other 2 treatment groups.(ABSTRACT TRUNCATED AT 250 WORDS)

[Effect of intensive movement rehabilitation and breathing exercise on respiratory parameters in children with idiopathic stage-I scoliosis].

In 70 children with mild idiopathic scoliosis I degree by the method of Cobb, participating in two or several rehabilitation camps, and in the control group of 22 healthy children ventilatory lung parameters: vital capacity--FVC, FVC%pred., Maximal forced expiratory volume one sec.--FEV1, FEV1%pred., FEV1% FVC, and Maximal Mid Expiratory Flow--MMEF, MMEF%pred. and Maximal Voluntary Ventilation--MVV were determined. Tests were carried out with use of the Vitalograph and Jaeger Spirometer after several four-week rehabilitation camps. Intensive movement rehabilitation with breathing exercises and relaxation with Yoga was used in children. The mean values of spirometric parameters were correlated between the examined groups and statistically significant increased values of parameters MMEF% pred., MVV were defined in the group of children with scoliosis.

A comparison of two breathing exercise programs for patients with quadriplegia.

This study compared the use of abdominal weights (AbWts) to inspiratory resistive muscle training (IMT) on selected measures of pulmonary function. Eleven patients, aged 16 to 41 years (mean = 27.8, SD = 8.3) with complete cervical injuries were randomly assigned to either an AbWts or IMT treatment group. Subjects in both treatment groups received daily treatments (five times weekly) for 7 weeks. Forced vital capacity (FVC), inspiratory capacity (IC), maximal voluntary ventilation (MVV), peak expiratory flow rate (PEFR), and inspiratory mouth pressure (PImax) were measured weekly. Analysis of variance for repeated measures showed no difference between the AbWts and IMT treatments; there were significant differences within each respective treatment group for all five variables. Although the data did not support the effectiveness of one method of training over the other, the larger increase in MVV with the IMT protocol may be indicative of an endurance training effect with this protocol. Future research should compare the effects of breathing exercise training to spontaneous recovery of the respiratory muscles in control subjects.

Exercise breathing pattern during chronic altitude exposure.

Breathing pattern in response to maximal exercise was examined in four subjects during a 7-day acclimatisation to a simulated altitude of 4247 m (barometric pressure, PB = 59.5 kPa). Graded exercise tests to exhaustion were performed during normoxia (day 0), and on days 2 and 7 of hypoxia, respectively. Ventilation was significantly augmented in the hypoxic environment, as were both the mean inspiratory flow (VT/TI) and inspiratory duty cycle (TI/TTOT) components of it. VI/TI was increased due to a significant increase in tidal volume (VT) and a corresponding decrease in inspiratory time duration (TI). Throughout a range of exercise ventilation, TI/TTOT was increased due to an apparently greater decrease in expiratory time duration (TE) with respect to TI. In all cases, the relation between VT and TI displayed a typical range 2 behaviour, with evidence of a range 3 occurring at very high ventilatory rates. There was essentially no difference observed in the VT-TI relation during exercise between the normoxic and hypoxic conditions. No significant changes were observed in the breathing pattern in response to exercise within the exposure period (from day 2 to day 7), although there was a discernible tendency to a higher stage 3 plateau by day 7 of altitude exposure.

Restoration of lung volume using the Flutter VRP1 or breathing exercise.

A method of chest wall restriction imposed for 30 minutes demonstrated a mean (SD) decrease of 42 (14) per cent in forced vital capacity (FVC) during restrictor application. Following the application of chest wall restriction, 30 healthy subjects then underwent a 15 minute treatment with either Flutter VRP1 (Flutter) or breathing exercise with end-inspiratory hold (BE) after chest wall restriction release. Both Flutter and BE applied for 15 minutes immediately restored FVC to pre-restriction values. Tidal breathing control subjects demonstrated a clinically small but statistically significant decrease in FVC of 3 per cent (p<0.001). Visual analogue assessment of each treatment technique showed BE to be the subject- preferred technique for lung volume restoration. This study shows that in normal subjects, Flutter and BE are equally effective in restoring FVC and superior to tidal breathing.

Device-guided breathing exercises reduce blood pressure: ambulatory and home measurements.

Slow breathing practiced routinely using an interactive device has demonstrated a sustained reduction in high blood pressure (BP). We reevaluated the BP response of hypertensives (n = 13) to this daily treatment for 8 weeks using 24-h ambulatory, home, and office BP measurements. A clinically significant BP reduction of similar magnitude was observed in all BP monitoring modalities during the daytime. Greater BP reductions were found for older patients and higher baseline BP. The results provide additional support for the efficacy of the device as an adjunctive lifestyle modification for treating hypertension.

Sulfur dioxide-induced bronchoconstriction in freely breathing, exercising, asthmatic subjects.

The purpose of this study was to determine whether 0.50 ppm sulfur dioxide (SO2) in filtered air causes bronchoconstriction in freely breathing asthmatic subjects exercising at a moderately heavy work rate. Ten volunteers who had mild asthma breathed air containing no SO2 or containing 0.50 ppm SO2 In an exposure chamber as they exercised for 5 min on a cycle ergometer at a work rate of 750 kilopond meters/min (about 125 watts). We determined their specific airway resistance by body plethysmography before and after exercise. Specific airway resistance increased by 13.55 +/- 9.18 cm H2O X s (mean +/- SD) when subjects exercised and breathed 0.50 ppm SO2 but only by 2.24 +/- 2.34 when they exercised and breathed air without SO2 (p less than 0.005). Thus, 0.50 ppm SO2 causes significant bronchoconstriction in freely breathing asthmatics during moderately heavy exercise.

Influence of exercise hyperthermia on exercise breathing pattern.

Passive elevation of the body core temperature (Tc) induces rapid, shallow breathing in resting man. We wondered if exercise-induced Tc elevation would also lead to decreased tidal volume (VT) and increased breathing frequency (f) during exercise. To investigate this question, 10 subjects each performed 47 min of cycle ergometer exercise at 50--60% of the maximal aerobic capacity, with the work rate adjusted to maintain ventilation (VE) constant. This long ride raised mean Tc (rectal) 0.8 degrees C. Before and immediately after the long ride, ranges of VE and VT were obtained from short 6-min rides that progressed from unloaded pedaling to the anaerobic threshold. At the constant VE of the long ride, f rose and VT fell as Tc rose (P less than 0.05). The fall in VT was associated with a fall in inspiratory time (TI); drive (VT/TI) and timing (TI/Ttot)components of VE were unchanged. These effects were consistent over the entire range of VE obtained from the short 6-min rides. Passive heating in warm water to produce equal Tc elevation in the same subjects yielded similar exercise breathing-pattern changes. These findings suggest that increased Tc mediates the VT fall during prolonged exercise, possibly through stimulation of the central respiratory pacemaker.
