| 20080236585 | INDICATING DEVICE FOR A VENTILATOR - An indicating device assists rescue personnel in administering cardiopulmonary resuscitation (CPR). A transducer measures the pressure drop in a flow tube attached to the patient, and this pressure drop is converted into a flow rate and volume. Another transducer measures the pressure in the flow tube at a point near the patient, the measured pressure being essentially the same as, or related to, the intratracheal pressure. Indicator lights show either red or green or yellow, when the flow rate, and/or the intratracheal pressure, are within or outside of a preferred range. The desired ranges can be adjusted according to the weight of the patient. The device provides immediate guidance for rescue personnel, by indicating whether the volume of gas received by the patient is appropriate, and whether intratracheal pressure is below or above a potentially lethal level. It also provides a prompt light to indicate the desirable rate at which to administer respirations, a rate based upon the measured values of the exhaled volume and the intratracheal pressure. | 10-02-2008 |
