OG exemplary drawing
 
1. A lightweight, compact, and portable apparatus to facilitate simultaneous ventilation and resuscitation of a patient, the apparatus comprising:
an inspiration control valve disposed downstream of an oxygen source having a gas that includes oxygen;
a connector configured to interface with a suppraglottic airway device disposed downstream from the inspiration control valve, the suppraglottic airway device configured to form an air seal such that the gas including oxygen can flow from the oxygen source through the connector;
an expiration control valve configured to selectively actuate a one-way exhalation valve;
an indicator providing a rate of at least 100 audio, visual, or audiovisual indications per minute;
a pressure relief valve between the inspiration control valve and the suppraglottic airway device, the pressure relief valve being configured to actuate and release gas if pressure at the pressure relief valve increases beyond a predetermined threshold so as not to exceed a peak inspiratory pressure of 26 cm H2O relative to atmospheric pressure;
a control system, configured to:
selectively open the inspiration control valve to allow the gas to flow from the oxygen source to the airway device for about 400 to 420 ms during an inspiration cycle and then close the inspiration control valve while simultaneously opening the expiration control valve to allow one-way venting of air from the airway device to the atmosphere during an expiration cycle, at a rate of less than 15 times per minute while the pressure relief valve is controlled to ensure that the peak inspiratory pressure does not exceed 26 cm H2O relative to atmospheric pressure so as to deliver to the patient a tidal volume corresponding to at least the patient's size or the patient's lung condition without creating a pulmonary barotrauma or a gastric distension condition in the patient, wherein the selectively opening and closing of the inspiration and expiration control valves is synchronized with the indications,
a timer configured to synchronize the actuation of the inspiration control valve and the expiration control valve; and
a switch configured to activate the timer such that in response to actuating the switch, the apparatus begins to automatically switch between the inspiration cycle and the expiration cycle without any further external input to the apparatus;
wherein the lightweight, compact, and portable apparatus has a weight that does not exceed about 28.6 ounces.
