Acute exposure to high altitude can affect the cardiovascular system by decreasing oxygen in the blood (acute hypoxia). It also increases demand on the heart, adrenaline release and pulmonary artery pressures.

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.
