Question

Which of the following is FALSE about continuous positive airway pressure (CPAP)?

a.It maintains alveoli at greater inflation volumes.
b.It holds airway pressure essentially constant.
c.It provides the pressure gradient needed for ventilation.
d.It has side effects similar to those of positive pressure ventilation.

Answer 1

The FALSE statement about CPAP is that "It provides the pressure gradient needed for ventilation." CPAP's role is to keep the airways open by maintaining constant positive pressure, not to create a ventilation pressure gradient.

Step-by-step explanation:

The statement about continuous positive airway pressure (CPAP) that is FALSE is "It provides the pressure gradient needed for ventilation." CPAP maintains positive pressure in the airways, not to create a pressure gradient for ventilation but to keep the airways open. In contrast, the pressure gradient for ventilation is accomplished naturally by the difference in pressure during the respiratory cycle. Let's dissect the options:

• 
  
• 
  
• 
  
• 
  

Sleep apnea treatments like CPAP are effective in preventing airway collapse during sleep and are an important part of managing the condition.
