11. It is not unusual for subcutaneous emphysema to result from positive pressure ventilation. 12. This combines positive pressure breathing with a counterpressure vest to protect the chest. 13. In cabinet laboratories, all work must be done within a positive pressure suit. 14. I don't see how an injection is faster than a positive pressure mask. 15. Since the introduction of tracheal intubation, this effect is achieved by positive pressure ventilation. 16. Positive pressure coincides with a deceleration as does the gravity of energy and mass.17. Once positive pressure stops, the diaphragm automatically flexes back to its original closed position. 18. Today, positive pressure ventilators are standard therapy for respiratory failure. 19. Positive pressure ventilators reduced mortality in bulbar patients from 90 % to 20 %.20. To maintain positive pressure the room should be sealed to prevent egress of air.
