The mean difference of the respiratory rate between the respiratory effort
belt and Vital-SCOPE was 0.47 breaths per minute (bpm) with the 95% limit of agreement ranging from -7.4 to 6.5 bpm.
SDB can be divided into obstructive sleep apnea/hypopnea (OSA), which is defined as five or more apnea/hypopnea episodes per hour (apnea/hypopnea index, AHI) that occur due to obstruction of upper airways, combined with extreme respiratory effort
and central sleep apnea (CSA), which is defined the same as OSA but without traceable respiratory effort
during apnea/hypopnea episodes (55-60).
She experienced ocular muscle weakness and worsening respiratory effort
resulting in hypoxia and hypercapnia.
Musicians performing wind instruments are particularly prone to the excessive respiratory efforts
and a prolonged performance of wind instruments may lead to the respiratory muscles overload .
Aside from RR, the nurse should observe for (and document) signs of increased respiratory effort
such as nasal flaring, pursed lips, grunting in infants, use of accessory muscles, wheezing or coughing.
After 2 h, child's respiratory pattern altered with poor respiratory effort
and Sp[O.sub.2] 60% at 5 liters of oxygen by face and mask.
Physical examination was unremarkable; respiratory effort
, mental status, and strength testing were normal.
In cattle, subcutaneous and pulmonary emphysema has been attributed to bellowing in cases of rabies in Southern Africa (SWANEPOEL, 1994), probably due to respiratory effort
. However, in the present case, the bull had no bellowing history.
The temperature may be increased slightly, with a more obvious respiratory effort
and occasionally a cough.
This suggests that the observed changes in intercostal muscle were not a systemic but a local effect of respiratory effort
Relationship of respiratory effort
sensation to expiratory muscle fatigue during expiratory threshold loading.
The investigators expected that an improvement in expiratory muscle strength following 4 wk of EMST would reduce the sensation of respiratory effort
during treadmill exercises.
