The “Minivent” ventilator is a small, convenient ventilator which has performed well in both the laboratory and the clinical situation. Its major disadvantage is the difficulty of monitoring ventilation in the unmodified circuit, but this has been overcome satisfactorily by the use of the Adelaide bag‐in‐bottle circuit. A further major disadvantage is the tendency of the ventilator to jam if the compliance is suddenly reduced, as occurs if the patient coughs or strains. Again, this is less likely to happen with the bag‐in‐bottle arrangement, but in any case it can be anticipated by careful observation and overcome by temporary disconnection of the machine. The modification is also more economical in that it uses air as the driving gas, thus conserving oxygen.
