    • This invention is a method and apparatus for liquid ventilation to increase the efficacy of cardiopulmonary resuscitation (CPR). The method includes replacing gas in the lungs with an oxygen and carbon dioxide carrying liquid to eliminate the decreased pumping efficiency of the heart seen during conventional or active compression/decompression (ACD) closed chest CPR without a mechanical respirator. An advantage is provided by supplying a continuous flow of liquid (or gaseous) ventilation medium throughout the entire chest compression/re-expansion cycle, accelerating both gas exchange and cooling or warming of the patient or animal subject. In the apparatus (100), breathing liquid returns from a patient via tube (101) and is supplied via tube (190), tubes (101, 190) being connected to an endotracheal tube (200). The apparatus includes a reservoir (110), an oxygenator (120), and a heater (130).

    • A process is provided for controlling a ventilation procedure wherein a liquid ventilation system passes breathing liquid through at least a portion of a patient's pulmonary pathways. In this process, desired ranges for certain process parameters associated with the liquid ventilation system are established. These desired ranges are input into a central processing unit (50). Initial settings for the liquid ventilation system are then made such that the actual conditions which will initially occur during the liquid ventilation procedure fall within their respective desired ranges. Thereafter, the procedure is commenced. During the procedure, conditions are continually monitored by sensors (16, 21, 27). The CPU (50) compares the sensor readings with the desired ranges, and acts to correct any discrepancy. The CPU can trigger alarms (514).

    • A dispenser (1) comprises a can (2) and a body (3). The can is an aluminium extrusion with a valve crimped into its mouth, the valve having an outlet spout (4). The crimped region (5) of the can surrounding the valve has a lesser diameter than the can has through the main part (6) of its length. The body has a mouthpiece (11) with a pivotal cover (12) drivingly connected to a cam (13). This bears on the underside of a junction member (14), into a socket (15) of which the spout 4 fits. A breath actuated dose release mechanism (16) is provided. The body has a tubular section (7) for receiving the necked down region (5) of the can. The tubular section and the main part of the can having the same external diameter. A printed paper label (21) coated with self-adhesive is wrapped around the joint between the body and the can to unite the can to the body in position such that when the cover is opened, a dose is dispensed by the cam (13) lifting the junction member and depressing the spout. In order to establish correct positioning of the can with respect to the body, prior to positioning of the label, a predetermined force (F) is applied to ensure that the spout is fully depressed. This causes the can to release into the release mechanism a dose, which will usually be a metered dose. Thus in this position of the can in the body, when the cover is opened in use, another dose will be released. With the force still applied the label is applied to the can and the body fixing their relative position.

    • Devices and methods to heat and cool human beings, including inducing and maintaining hypothermia in human patients. Methods include inducing hypothermia to treat ischemic events, including heart attack and stroke, to limit damage caused by the ischemic event. Methods can include: using the lungs for heat exchange; using cooled gases for ventilation; using helium in the ventilation gas mixture, using medications to control reflex heat production; and injecting a perfluorocarbon mist into the gas stream to increase the cooling rate. The high thermal conductivity and diffusivity of helium results in greater inspired gas temperature equalization toward body temperature. Due to the latent heat of vaporization, addition of even small quantity of phase-change perfluorocarbon dramatically increases the heat carrying capacity of the respiratory gases. Hypothermia may be terminated by discontinuing the medications and warming the patient using a warmed helium-oxygen mixture.
