This power point may be useful for those who are not working in ICU but need to know something basic about mechanical ventilation.It is absolutely not designed to be a cover all basic points.

ATTEMPTED IN THE TRUNK OF THE TRACHEA, INTO WHICH A TUBE OF REED OR
CANE SHOULD BE PUT; YOU WILL THEN BLOW INTO
THIS, SO THAT THE LUNG MAY RISE AGAIN AND TAKE AIR”
