Filter by:High-humidity nasal cannula (HFNC) has been shown to be effective in improving oxygenation and avoiding intubation in multiple randomized control trials, it is also suitable and feasible for long term use. Aerosol delivery via HFNC will minimize interruptions and improve patient compliance, bench study and radionuclide imaging study done in healthy volunteers demonstrated that aerosol can be effectively delivered using HFNC. This study aims to evaluate the efficacy of bronchodilator delivered via HFNC in chronic pulmonary obstructive disease or asthma patients.
Noninvasive ventilation (NIV) is an alternative form of ventilatory support in critical care encompassing different modes of ventilation such as continuous positive airway pressure (CPAP), bilevel positive airway pressure (BiPAP) and high flow nasal cannula ventilation. Although numerous studies on adults exit in literature, the aspects of this ventilatory support is limited in pediatric age groups. Early recognition of respiratory failure and initiation of NIV in a pediatric patient would positively affect prognosis by avoiding certain complications of endotracheal intubation and mechanical ventilation and adds certain advantages. Decreasing re-intubation rates for the ones who are extubated but necessitating further oxygen support is another advantage of NIV. Although numerous studies on adults exit in literature, the aspects of this ventilatory support is limited in pediatric age groups. Besides, success as well as failure and complication rates in pediatric age groups vary extensively. This multi-centered, prospective cohort study is planned to observe the epidemiologic perspectives of study group within underlying problems, success rates between different age groups, complication and re-intubation rates and finally its' effect on prognosis and long term survival in a year period. Hence we believe results of this study would allow us to improve our knowledge on using this technique, applying different modes and parameters appropriately and design criteria to guide clinician in deciding which group of patients would benefit from NIV techniques.
High-flow nasal cannula (HFNC) that uses heated and humidified oxygen was recently introduced for bedside care. It has been shown to be associated with reduced risks of tracheal intubation rates and mortality in adult hypoxic patients. The mechanisms of the effects of HFNC are thought to be related to the favorable effects of the heated and humidified gas, the high-flow rate used to minimize the entrainment of room air, and an increase in the ventilation efficiency, including the elimination of nasopharyngeal dead space, positive end-expiratory pressure (PEEP) effects, and improvements in paradoxical abdominal movement. Regarding the effects on lung volume, global ventilation in the lungs increases during HFNC, which is thought to attribute to PEEP effects. However, how regional ventilation is affected during HFNC in comparison with conventional NC remains unknown. Because PEEP in mechanically ventilated patients improves the regional homogeneity of ventilation, investigators postulated that HFNC via PEEP effects would result in more homogeneous regional distributions in the ventilation changes. Investigators therefore assessed global and regional ventilation in patients with hypoxia receiving care via HFNC using electric impedance tomography and compared these results with conventional nasal cannula.
High-flow nasal cannula (HFNC) is a method of non-invasive respiratory support used to decrease the effort of breathing (EOB) in patients with a wide variety of respiratory diseases in the pediatric intensive care unit. While its use has shown association with decreased rates of mechanical ventilation, there is a paucity of data examining its direct effect upon objective measurements of EOB. This study will aim to evaluate objective measurements of EOB in response to different levels of HFNC support, characterize the natural course of respiratory diseases treated with HFNC, evaluate changes in EOB secondary to the administration of supplemental medical therapies used in conjunction with HFNC, and compare different physiologic metrics for quantifying EOB in patients on HFNC.
