13. Cervical Spine Motion in Football Players During 3 Airway-Exposure Techniques
Objective: Immediate rescue breathing, or cardiopulmonary resuscitation, may be necessary for the cervical spine-injured football player without removal of the helmet. The purpose of our study was to compare 2 pocket-mask insertion techniques with a face-mask rotation technique to determine which allowed the quickest initiation of rescue breathing with the l

14. Metabolic rate at rest and during sleep in a thermoneutral environment.
This study characterised the pattern of oxygen consumption (VO2) in healthy infants and children asleep and awake (at rest) in a thermoneutral environment. Measurement of respiratory gas exchange (VO2 and VCO2) was made using an open circuit flow through system of indirect calorimetry with a specially designed facemask for the collection of exhaled breath.

15. Prevention of viral induced asthma attacks using inhaled budesonide.
Thirty two preschool children were entered into a double blind, placebo controlled study using intermittent budesonide to treat viral induced wheeze. Active treatment was either 800 micrograms twice a day via a spacer or 1600 micrograms twice a day via a spacer and facemask in those children too young to use a mouthpiece. Treatment was started at the onset o

16. Efficacy of cromoglycate in persistently wheezing infants.
A prospective study was undertaken to evaluate the efficacy of (sodium) cromoglycate in the treatment of persistent wheezing in 31 children between 4 and 12 months of age. The subjects were randomised to receive either 40 mg of cromoglycate (n = 16) or physiological saline as placebo (n = 15) three times a day by wet nebulisation in a double blind fashion fo

17. Delivery of salbutamol by metered dose inhaler and valved spacer to wheezy infants: effect on bronchial responsiveness.
The efficacy of a new valved spacer device, the Babyhaler inhaler (Glaxo) for administering metered dose inhaler treatment via a facemask to infants was assessed. In a double blind, single dose study, salbutamol (800 micrograms) or placebo were given on separate days to 12 sedated, sleeping, wheezy infants during a symptom free interval. Lung function was me

18. Effectiveness of a heat and moisture exchanger in preventing hyperpnoea induced bronchoconstriction in subjects with asthma.
The effect of a heat and moisture exchanger, a device with hygroscopic material for conditioning inspired air, on hyperpnoea induced bronchoconstriction was studied in nine non-smoking volunteers with asthma, aged 19-32 years. Each had previously shown an increase of at least 100% in specific airways resistance (sRaw) to isocapnic hyperpnoea with dry air. On

19. The effect of sleep on reflex genioglossus muscle activation by stimuli of negative airway pressure in humans.
The present study was designed to determine the effect of sleep on reflex pharyngeal dilator muscle activation by stimuli of negative airway pressure in human subjects. Intra-oral bipolar surface electrodes were used to record genioglossus electromyogram (EMG) responses to 500 ms duration pressure stimuli of 0 and -25 cmH2O applied, via a face-mask, in four
