QuestionAnswer
What is IPPB used for? For preventing or correcting Atelectalis in patients unable to take a deep breath
What are two main Contradictions of IPPB Massive pulmonary hemorrhage and Untreated pneumothorax
What are some hazards of IPPB Hyperventilation,Air trapping,Gastric distention, pneumothorax, Impeding venous return
Name 3 types of Pressure Cycled ventilators Bird Mark 7 Bennett PR II- Respirator Bennett AP4 and AP6
What classification is the Bird Mark 7 Positive pressure Pneumatically powered Time/Patient triggered Pressure cycled Assist, Control modes Flow adjustable
What classification is the Bennett II Positive Pressure Pneumatically powered time/patient triggered pressure limited flow cycled time limited flow adjustable
What classification is the Bennett AP-4 and AP-5 Positive pressure Electrically powered compressor driven patient trigger (AC mode only) flow cycled pressure limited Appropriate for home setting
Control Changes that will change the volume 1. Increasing the pressure 2. Decreasing the flow 3. Increase the flow will increase turbulence and decrease volume 4. Air-Mix and Sensitivity have no effect.
Changes in delivered volume with changing Compliance and Airway Resistance Lung status change:Increase compliance, decrease resistance Volume Change: Increase **Best Scenario**
What cause Loss of pressure Leak or insufficient flow
What causes excessive pressure Obstruction or excessive flow
Why does the machine fail to cycle into inspiration Adjust sensitivity tight seal around mouthpiece
What to check if machine fails to cycle off mouthpiece/mask leak cuff leaking Fenestrated trach tube open loose equipment connection
If pressure does not rise normally what is the problem Insufficient flow
Indications for NPPV 1.To avoid intubation in patients with COPD, CHF and Pulmonary Edema. 2. Facilitate long-term ventilation at home. 3. Provide periodic support- neuromuscular disease , restrictive chest wall disease, central/obstructive sleep apnea
IPAP and EPAP IPAP is always set higher. If you change EPAP, you must change IPAP. IPAP is for Ventilation. EPAP is for oxygenation.
