Q

When does gas atelectasis occur?

A

Q

When does compression atelectasis occur?

A

When the trans thoracic pressure( pressure difference between the body surface and alveoli) exceeds the transalveolar pressure(the pressure difference between the Alveoli and pleural space)

Q

What is the purpose of IS?

A

To coach the pt to take a sustained maximal Inspiratory effort resulting in a decrease in pAL and maintaining the latency of airways at risk for closure

Q

What does the baseline assessment include before beginning therapy?

A

A general evaluation of pts clinical status and a specific assessment related to the chosen therapeutic goals.

Also measuring vitals, assessing the pt appearance and sensorium, assessing the breathing patterns through chest auscultation, and the pts level of motivation and their ability to follow instructions

Q

Contraindications to incentive spirometry:

A

Pt cannot be instructed or supervised to ensure appropriate use of device, pt cooperation is absent or patient is unable to understand or demonstrate proper use of device, and pt is unable to deep breathe effectively (VC < 10 ml/kg or IC < 1/3 of predicted)

Q

Potential outcomes of incentive spirometry:

A

Decrease or elimination of atelectasis, improved breath sounds, normal or improved chest x-ray, increased Sp02, increased VC, improved inspiratory muscle performance and cough
