Q

A hole or tear in the bellows my result in?

A

Hyperventilation
Hyperoxia
Barotrauma
Patient awareness

2
Q

Excessive airway pressure maybe caused by?

A
  1. Activating the oxygen flush during inspiration
  2. A hole in the bellow housing
  3. A stuck spill valve
3
Q

A standing bellows

A
  • expands during exhalation

- makes it easy to detect disconnections

4
Q

when a ventilator with a piston is used

A
  • Air entrainment may occur

- The reservoir bag may expand and contract with mechanical ventilation

5
Q

Regarding pressure control ventilation

A
  1. Flow is highest at the beginning of inspiration
  2. Tidal volume is not constant
  3. It is often used with supraglotic devices
6
Q

Regarding SIMV

A
  1. The ventilator has a secondary source of gas flow for spontaneous breathing
  2. It is often used to wean patients off mechanical ventilation
  3. A mandatory tidal volume and minimum mechanical ventilation rate must be selected.
7
Q

Regarding PSV

A
  1. Most ventilators have a backup or apneic rate.

2. The pressure waveform has a square, flat top shape
