Chronic lung diseases are increasingly recognized complications of vertically-acquired HIV among adolescents in sub-Saharan Africa and may manifest with hypoxia or tachypnea. We sought to determine the prevalence of and risk factors for hypoxia and tachypnea among adolescents with
OBJECTIVE
To compare the performance of respiratory rate and other clinical signs against pulse oximetry for predicting hypoxia in children with Severe pneumonia/Very severe disease as per Integrated Management of Neonatal and Childhood Illness (IMNCI) classification.
METHODS
Cross-sectional
In carotid body-denervated cats, moderate hypoxia, or even normoxia when compared to hyperoxia, provokes a significant depression of the respiratory output. This is observed in conscious or anesthetized or decerebrated animals. On the other hand, more severe hypoxia induces tachypnea (hypoxic
Ventilation while breathing air and in response to hypoxia was studied in unanesthetized cats after carotid body chemo-defferentation. Hypoxic exposure (FIO2 equal to 0.07-0.12) of chemo-deafferented animals rapidly produced a high frequency, low tidal volume tachypnea. Tachypneic breathing,
BACKGROUND
It has been demonstrated that aspirations could occur during respiratory failure, explained by a lack of co-ordination between swallowing and ventilation. To test this hypothesis, we examined the co-ordination of ventilation and swallowing in a completely unrestrained rat model during
The rapid shallow breathing of pulmonary vagal origin following administration of histamine (H) and phenyldiguanide (PDG) was studied at different levels of hypercapnic and hypoxic stimulation. At all levels of chemical drive H and PDG caused an excitatory effect on timing of breathing and an
OBJECTIVE
To completely compare the risk factors, respiratory therapies and complications between respiratory distress syndrome (RDS) and transient tachypnea of newborn (TTN) in preterm infants.
METHODS
Data were collected from preterm infants in Department of NICU, Peking University Third Hospital
We report a case of delayed hypoxemia in an aged healthy male patient, which developed 2 hours after cementation of the prosthesis in total hip replacement (THR) under spinal anesthesia. The patient was doing well throughout the operation but unfortunately, progressive tachypnea was noted 1 h after
The growing Hg input in aquatic environments results in high accumulation of mercury in fish tissue and their consumers, which poses a serious risk to humans and ecosystems. The aim of this study was to evaluate the effects of the inorganic mercury exposure on cardiorespiratory responses in two
BACKGROUND
Childhood interstitial lung disease (chILD) is a heterogeneous group of rare disorders characterized by abnormal imaging findings, impaired gas exchange; and is associated with substantial morbidity and mortality. Neuroendocrine cell hyperplasia (NEHI) is a unique sub-group, which is more
To test the hypothesis that hypoxia and hypercapnia have different effects on the genesis of respiratory sinus arrhythmia (RSA), the magnitude of RSA to these stimuli was compared in 3 unanesthetized dogs. Respiration was continuously monitored through a permanent tracheostomy, and the
Effects of steady-state hypoxia (inspired O2 fraction = 0.11) on ventilation and breathing pattern were studied during postnatal development in unanesthetized kittens. Studies were done from 2 days to 8 mo of age, every week during the first month and every month thereafter. During the first 2
