Home bi-level positive pressure ventilators are equipped with built-in softwares which measure and record specific items such as tidal volume, total ventilation, leaks, respiratory rate, cycles triggered by the patient. These items have not to date been described in a large group of patients under home mechanical ventilation.
Observational study of patients under home positive pressure mechanical ventilation, in a stable condition.
Data recorded by ventilator software is downloaded by specialized nurses during elective home visits, as well as spirometry, results of recent pulse oximetry, ventilator settings, diagnosis, and basic anthropometric data.
Items recorded by ventilator software are: tidal volume, total ventilation, apnea and hypopnea index, leaks, percentage of inspiratory cycles triggered by ventilator, spontaneous and back-up respiratory rates.
Results are reported by diagnostic group. Statistical analysis (univariate and multivariate) aims to determine which variables are related to unintentional leaks, and whether ventilator settings differ significantly between diagnostic groups.

It is controversial as to which ventilation mode is better in one-lung ventilation(OLV), volume controlled ventilation(VCV) or pressure controlled ventilation(PCV). This study was designed...
The investigator will compare the feasibility of manual ventilation and pressure-controlled mechanical ventilation during facemask ventilation in children. The hypothesis is that the incid...
In this study, we want to compare two different kinds of artificial ventilation to see if one encourages faster weaning from breathing support and if one provides better sleep quality. The...
The purpose of this study is to find a proper ventilation strategy for one-lung ventilation to prevent postoperative pulmonary complications
The purpose of this research study is to compare difference between breathing by oneself or with the partial help from an anesthesia machine in children under general anesthesia.
The effects of different ventilation strategies during CPR on patient outcomes and lung physiology are still poorly understood. This study compares positive pressure ventilation (IPPV) to passive oxyg...
Airway management and ventilation during a tracheobronchial stenting procedure are challenging given that mandatory positive pressure ventilation cannot be fully achieved while using a rigid bronchosc...
Computed tomography (CT) and spirometry are the current standard methods for assessing lung anatomy and pulmonary ventilation, respectively. However, CT provides limited ventilation information and sp...
Four-dimensional computed tomography (4D-CT) ventilation is an emerging imaging modality. Functional avoidance of regions according to 4D-CT ventilation may reduce lung toxicity after radiation therap...
The optimal ventilation strategy in patients receiving mechanical ventilation for severe asthma remains unclear. The effect of conventional ventilation (with constant tidal volume and respiratory rate...
Ventilatory support system using frequencies from 60-900 cycles/min or more. Three types of systems have been distinguished on the basis of rates, volumes, and the system used. They are high frequency positive-pressure ventilation (HFPPV); HIGH-FREQUENCY JET VENTILATION; (HFJV); and high-frequency oscillation (HFO).
Techniques for effecting the transition of the respiratory-failure patient from mechanical ventilation to spontaneous ventilation, while meeting the criteria that tidal volume be above a given threshold (greater than 5 ml/kg), respiratory frequency be below a given count (less than 30 breaths/min), and oxygen partial pressure be above a given threshold (PaO2 greater than 50mm Hg). Weaning studies focus on finding methods to monitor and predict the outcome of mechanical ventilator weaning as well as finding ventilatory support techniques which will facilitate successful weaning. Present methods include intermittent mandatory ventilation, intermittent positive pressure ventilation, and mandatory minute volume ventilation.
Mechanical ventilation delivered to match the patient's efforts in breathing as detected by the interactive ventilation device.
Ventilation of the middle ear in the treatment of secretory (serous) otitis media, usually by placement of tubes or grommets which pierce the tympanic membrane.
Respiratory support system used primarily with rates of about 100 to 200/min with volumes of from about one to three times predicted anatomic dead space. Used to treat respiratory failure and maintain ventilation under severe circumstances.
