  • Patent number: 8251914
    Abstract: A method of sampling one or more respiratory profile characteristics and monitoring a variety of respiratory profile parameters. The sampled respiratory characteristics include respiratory flow rate, respiratory pressure, and partial pressure of at least one constituent of a patient's respiration. The method detects patient breaths, determines whether each breath is a spontaneous breath or a ventilator-induced breath and calculates various respiratory profile parameters based on the sampled measurements. The method displays the respiratory profile parameters in graphic and numeric forms. Preferably, the method allows a user to select the displayed respiratory profile parameters.

  • Patent number: 6408848
    Abstract: The present invention provides a method and device for conveniently setting the volume of a variable-length tubing loop used in a re-breathing circuit to various selected predetermined values. The device includes a card of an inelastic, disposable material which is attachable to a portion of the tubing loop or adjacent structure and which has marked on it several positions to which the tubing loop can be extended to set the volume of the loop at selected predetermined values. The card is preferably formed of a substantially rigid material which may be configured to fold around the tubing loop and adjacent structures to provide support and protection during shipping and handling of the device. The card may include instructions for use of the tubing loop printed on an outer surface thereof. Some or all of the card may be detachable from the tubing loop so that once the desired tubing volume is set, all or a portion of the card may be removed and disposed of.

  • Patent number: 5535232
    Abstract: The present invention is a solid state laser, including: (1) a laser cavity defined by a first mirror and an opposing second mirror, where these mirrors are reflective at the output wavelength of the laser; (2) a laser medium disposed in the laser cavity, including a low phonon energy host material, doped with an amount of praseodymium ions sufficient to produce a longitudinal mode laser emission from the transition of the praseodymium ions from the .sup.3 F.sub.3 excited state to a lower energy state when the laser medium is pumped by an appropriate pump, where the energy gap between the .sup.3 F.sub.3 excited state and the lower energy state corresponds to the output wavelength of the laser; and (3) a pump for the laser medium.

  • Patent number: 4864580
    Abstract: A pulsed CO.sub.2 laser that eliminates the nitrogen tail on the pulse by placing a Brewster angle absorption cell inside the optical cavity of the laser. This Brewster angle absorption cell contains a gas which exhibits a preferential absorption in the 10 .mu.m spectral regime. This preferential absorption causes the laser to lase in the 9.6 .mu.m regime which allows for easier harmonic generation and elimination of the nitrogen tail.

  • Patent number: 4526664
    Abstract: The invention relates to an improved method and apparatus for laser isotope separation by photodeflection. A molecular beam comprising at least two isotopes to be separated intersects, preferably substantially perpendicular to one broad side of the molecular beam, with a laser beam traveling in a first direction. The laser beam is reflected back through the molecular beam, preferably in a second direction essentially opposite to the first direction. Because the molecules in the beam occupy various degenerate energy levels, if the laser beam comprises chirped pulses comprising selected wavelengths, the laser beam will very efficiently excite substantially all unexcited molecules and will cause stimulated emission of substantially all excited molecules of a selected one of the isotopes in the beam which such pulses encounter. Excitation caused by first direction chirped pulses moves molecules of the isotope excited thereby in the first direction.
