Chronic hypoventilation syndromes and sleep-related hypoventilation.
Chronic hypoventilation affects patients with disorders on any level of the respiratory system. The generation of respiratory impulses can be impaired in congenital disorders, such as central congenital alveolar hypoventilation, in alterations of the brain stem or complex diseases like obesity hypoventilation. The translation of the impulses via spinal cord and nerves to the respiratory muscles...
متن کاملMuscle Cramps During Hemodialysis
Muscle cramps are the most prevalent intradialytic complication and an important difficulty for patients. The frequency of muscle cramps is about 35-86% during haemodialysis. Excessive ultrafiltration, intradialytic hypotension, electrolyte-mineral disturbances , hypoosmolality are the most frequent causes. Muscle cramps can be treated by isotonic-hypertonic saline or hypertonic dextrose soluti...
متن کاملHypoventilation and apnea in children during mechanically assisted ventilation.
Uncuffed tracheostomy tubes are used for long-term mechanical ventilation in children. However, upper airway mechanics differ between sleep and wakefulness; this may affect air leak around tracheostomies. We studied 19 children with high cervical spinal cord injury on portable positive pressure ventilators, age range birth to 19 years. Ventilator settings were adjusted while awake to achieve Pa...
متن کاملDoes voluntary hypoventilation during exercise impact EMG activity?
It has been reported that exercise under hypoxic conditions induces reduced muscle oxygenation, which could be related to enhanced activity on electromyography (EMG). Although it has been demonstrated that exercise under conditions of voluntary hypoventilation (VH) evokes muscle deoxygenation, it is unclear whether VH during exercise impacts EMG. Seven men performed bicycle exercise for 5 min a...
متن کاملNon-invasive ventilation corrects alveolar hypoventilation during spinal anesthesia.
PURPOSE To document and explain the beneficial effects of non-invasive ventilation in correcting hypoxemia and hypoventilation in severe chronic obstructive pulmonary disease, during spinal anesthesia in the lithotomy position. CLINICAL FEATURES A morbidly obese patient with severe chronic obstructive pulmonary disease underwent prostate surgery in the lithotomy position under spinal anesthes...
