If one drive wheel turns more rapidly than the other, the machine moves along a curved path. If both wheels turn at the same speed, the machine follows a straight path. If one wheel stops and the other turns, or if the wheels turn in opposite directions, the mower pivots. [7] [9] [10] This drive system can be used on two types of zero-turn mowers:
Leakages in the system, such as may be caused by bronchial fistulae, will render this system less effective. [clarification needed] Other negative effects of this technology include increased secretions (i.e. mucus) and nosebleeds, either or which may clog an HME. In such cases, the application of active respiratory gas humidifiers is recommended.
The successful application of bubble CPAP requires elaborate nursing care. [6] There is a learning curve to the implementation of the bubble CPAP respiratory approach that requires a team effort. [2] Respiratory therapists are important members of the team. The system has to be snugly fitted and stationed on the infant's head.
CPAP is the most effective treatment for moderate to severe obstructive sleep apnea, in which the mild pressure from the CPAP prevents the airway from collapsing or becoming blocked. [ 1 ] [ 2 ] CPAP has been shown to be 100% effective at eliminating obstructive sleep apneas in the majority of people who use the therapy according to the ...
Colin Sullivan AO FAA is an Australian physician, professor, [1] and inventor known for his invention of the nasal continuous positive airway pressure (CPAP) machine for the treatment of sleep apnea. Sullivan began studying sleep apnea in the late 1970s. In 1981 he published a design for the first CPAP machine in The Lancet.
[1] HMEs are one type of commercial humidification system, which also include non-heated-wire humidifiers and heated-wire humidifiers. [1] HMEs have been in clinical use for over 30 years. [2] An HME cassette plays a central part of lung rehabilitation after a total laryngectomy. [citation needed]
A humidifier is a household appliance or device designed to increase the moisture level in the air within a room or an enclosed space. It achieves this by emitting water droplets or steam into the surrounding air, thereby raising the humidity.
Grasshopper was the first manufacturer to offer dual swing-out levers for their zero-turn mowers (1973) [2] and the first to offer a diesel-powered zero-turn mower (1983). [ 3 ] Grasshopper introduced the PowerFold Electric Deck Lift in 2004, to allow the operator to easily lift and rotate the mowing deck nearly 90 degrees for maintenance and ...
