Boomerang pillows and respiratory capacity.
An experimental study was done to determine whether subjects placed on boomerang pillows would have lower vital capacities than subjects placed on straight pillows after 30 minutes. A sample of 42 subjects took part in the study in a nursing laboratory. A crossover design was used in which subjects were measured in both conditions. The findings indicated that there was no significant difference in the vital capacities of subjects in the two conditions. An associated finding was that the vital capacities were significantly lower in a semi-Fowler's position than in a straight chair. It was concluded that boomerang pillows are safe to use for persons without respiratory problems. Further research is needed into the effect of boomerang pillows on persons with respiratory deficits.
