Objective To investigate the advantages and disadvantages of tracheotomy in patients with non-mechanical ventilation hood with traditional home-made oxygen mask within in order to provide a basis to guide clinical work. Method Tracheotomy non-mechanical ventilation were randomly divided into experimental group and control group

with experimental group consisting of 27 cases

line hood oxygen

and control group 27 cases and by the oxygen inside the casing

to compare SaO2 and pulmonary infection during suctioning rate

and to monitor the humidity and temperature inside the hood. Results The suction at different times of the SaO2 experimental group were higher（P

<

0.01）; pulmonary infection rates were 7.4% in the experimental group and 29.6% in control group

The difference was statistically significant（P

<

0.05）.Hood humidity is 95%

and temperature is 32℃

4℃. Conclusion Oxygen mask for the self-tracheotomy patients undergoing non-mechanical ventilation hood oxygen

can effectively reduce the suction when the SaO2 lower levels

help breathe air automatic heat

wet

and reduce lung infection.
