In chest tube drainage systems, the water seal chamber prevents air from re-entering the pleural space air escapes during expiration(with spontaneous breathing) and bubbles through the water the tube is inserted into 20 cm of water the tube is inserted into 2 cm of water

In administering IPPB therapy, which of the following breathing patterns would be most desirable?

Hazards associated with IPPB treatments include all of the following EXCEPT:

In the Bird Mark 7 or 8 IPPB devices, bypassing the venturi (by pushing the “air-mix” control IN) will have which of the following effects?           a decrease in available flow during inspiration        an increase in the end-inspiratory pressure        delivery of 100% source gas to the patient

The following is true regarding transtracheal aspiration A catheter is inserted through the cricothyroid membrane into the trachea Can be used to provide emergency ventilation Specimens are useful in diagnosing Legionnaires disease Used as a routine method of sputum removal for patients who cannot cough

During autogenic drainage, when should patients be encouraged to cough?

The following are true regarding Electromagnetic Interference (EMI): They are invisible waves that move through matter.  EMI waves are emitted by electronic transmitting devices.  EMI can cause hospital equipment to malfunction. Thick foam equipment covers are the best method to shield for EMI.

If a leak occurs while a Bird Mark 7 is being used, which of the following will happen?

Absolute contraindications for postural drainage include which of the following?   Head and neck injury (until stabilized) Active hemorrhage with hemodynamic instability Uncontrolled airway at risk for aspiration  

A patient receiving mechanical ventilation is on a three-bottle closed chest tube drainage system for correction of a pneumothorax.  You accidentally knock over and break the underwater seal.  Your immediate action would be:
