Mouthpiece ventilation (MPV) allows patients with neuromuscular disease to receive daytime support from a portable ventilator, which they can disconnect at will, for example, for speaking, eating, swallowing, and coughing. However, MPV carries a risk of underventilation. Our purpose here was to evaluate the effectiveness of daytime MPV under real-life conditions. Eight wheelchair-bound patients...

OBJECTIVES/HYPOTHESIS To demonstrate that neonatal ventilators can expose patients to high noise levels through bone conduction (BC) as well as air conduction (AC). STUDY DESIGN Observational study. METHODS Three ventilators and various settings on a positive airway pressure machine (continuous, high bilevel, and low bilevel pressure) were tested. A sound level meter was used to measure the...

-A Web application of a ventilator simulation system was developed for the students of clinical engineering and health care professionals. The system runs on Internet Explorer (5.5 or higher) and was developed using HTML, VBScript and Active X control (tklsim.ocx 70kB). The system was composed of a ventilator module and a respiratory model module. The ventilator module makes various waveforms o...

Early mobilization and aggressive physical therapy are essential in patients who receive left ventricular assist devices (LVADs) due to long-term, end-stage heart failure. Some of these patients remain ventilator dependent for quite some time after device implantation. We report our regimen of mobilization with the aid of a portable ventilator, in patients with cardiac cachexia and LVAD implant...

despite the similar performance of bazaar1 in different cities of iran, there are some the skeletal differences between markets in different climates. the bazaar roof protects customers against natural events in any climate. the ceiling height and the sitting down of the bazaar`s floor are determined based on the need for air circulation and movement in various climates. hence, combination of a...

Patient-ventilator interaction can be described as the relationship between 2 respiratory pumps: (1) the patient's pulmonary system, which is controlled by the neuromuscular system and influenced by the mechanical characteristics of the lungs and thorax, and (2) the ventilator, which is controlled by the ventilator settings and the function of the flow valve. When the 2 pumps function in synchr...

OBJECTIVES Although pediatric intensivists philosophically embrace lung protective ventilation for acute lung injury and acute respiratory distress syndrome, we hypothesized that ventilator management varies. We assessed ventilator management by evaluating changes to ventilator settings in response to blood gases, pulse oximetry, or end-tidal CO2. We also assessed the potential impact that a pe...

BACKGROUND Proportional assist ventilation+ (PAV+) delivers airway pressure (P aw) in proportion to patient effort (P mus) by using the equation of motion of the respiratory system. PAV+ calculates automatically respiratory mechanics (elastance and resistance); the work of breathing (WOB) is estimated by the ventilator. The accuracy of P mus estimation and hence accuracy of the delivered P aw a...

OBJECTIVE The ventilator bundle is being promoted to prevent adverse events in ventilated patients including ventilator-associated pneumonia (VAP). We aimed to: (i) examine adoption of the ventilator bundle elements; (ii) determine effectiveness of individual elements and setting characteristics in reducing VAP; (iii) determine effectiveness of two infection-specific elements on reducing VAP; a...
