If there is resistance to the BVM when ventilating a tracheostomy patient the EMT should check air is escaping through a hole in the lung and filling the pleural space.
<h3>What is tracheostomy?</h3>
A tracheostomy is a hole made in the front of the neck to allow a tube to be inserted into the windpipe trachea to assist breathing.
The tube can be connected to an oxygen supply and a breathing machine called a ventilator if necessary.
Individuals notice increased resistance to ventilations while ventilating an intubated patient with a bag-valve-mask-unit. This could mean that air is escaping from the lung and filling the pleural space.
Thus, the EMT should check for this.

Answer:
0.5
Explanation:
The nurse must ensure that the FIO2 must not be greater than 0.5. This is because if the FIO2 is even slightly greater than than for as little as 16 to 24 hours, it can get really toxic and then diffusion of gas and surfactant activity will be reduced drastically. In ideal circumstances, the oxygen source is expected to be room air and within a range of FIO2 0.18 - 0.21.
