When to use knightstar 330 bi-level ventilator?
The Puritan Bennett KnightStar 330ventilator is intended to assist patients with ventilation when they are experiencing respiratory insufficiency or obstructive sleep apnea. It is designed to help patients by providing two levels of pressure, referred to as inspiratory and expiratory pressure. Patients who use the
How does a bi-level ventilator work and how does it work?
The vent hole(s) allows a continuous flow of air out of the mask. When the device is turned on and function- ing properly, fresh air from the device flushes the exhaled air out through the mask vent hole. However, when the device is not operating, a substantial proportion of exhaled air and carbon dioxide may be rebreathed.
When do you not need a Smart Vent?
First, understand that smart vents can only restrict air flow. If you happen to have one room that doesn’t get enough air (cold in the winter and/or hot in the summer) that room would not need a smart vent. Instead, you would need smart vents on many of the other vents in the house. Then, you could close some of those vents.
How does a Smart Vent work with a thermostat?
When a vent is closed in one room, increased pressure in the system causes more air to be redirected to other rooms. In a smart vent system, the thermostat controls the on/off of the HVAC system and the smart vents direct where it goes. It’s ideal but not necessary to have the two devices be able to communicate with each other.

Pull the negative battery cable and re-install, making sure it is very tight (also check the positive to make sure it is tight). See if this fixes the problem.
How is the oversizing of a vent related to heat loss?
venting are the oversizing of the vent or reducing the BTUH input to an existing vent system. Either case will result in excessive cooling of the flue gases and a reduction of the vent forces. Heat Loss The amount of heat lost through the vent is based on two factors. They are: the ability of the vent pipe to transfer
