The ability of three different techniques of transtracheal ventilation to reverse hypoxia and provide pulmonary ventilation were examined. Five swine were anaesthetized with isoflurane in oxygen, their tracheas were intubated, and their lungs mechanically ventilated to produce a PaCO2 of 35-40 mmHg. A 14-gauge catheter was inserted percutaneously into the trachea caudad to the tip of the tracheal tube. The animals were then left apnoeic until their oxygen saturation fell to 60 per cent. At this point, attempts were made to ventilate and oxygenate the animals through the tracheal catheter with one of three systems (Jet--50 psi [2585 mmHg] driving pressure controlled with a thumb operated valve, Flush-fresh gas outlet of an anaesthetic machine with flow controlled by the flush button, or Circle--standard anaesthesia circle system with pressures greater than 60 mmHg). Arterial blood gas determinations were made every minute for five minutes after beginning transtracheal ventilation. Both the Jet and Flush modes resulted in a mean PaO2 greater than 250 mmHg within one minute of their initiation whereas the PaO2 with the Circle system never exceeded 180 mmHg even at five minutes. The Flush and Jet modes produced a decrease in the PaCO2 (from 80 mmHg to 35-45 mmHg) over the five minutes. In contrast, it was not possible to provide adequate ventilation with the Circle system as evidence by an increasing PaCO2 (from 80 mmHg to less than 110 mmHg at five minutes).(ABSTRACT TRUNCATED AT 250 WORDS)
