While the majority of previous research on NIV utilized single-limb circuits, there is no study in the literature that compares two types of ventilator circuits
on aerosol delivery during NIV.
Effect of frequency of ventilator circuit
changes (3 vs 7 days) on the rate of ventilator-associated pneumonia in PICU.
The inclusion criteria for this study were having nebulisers in the ICU at the time of audit that had been used within a ventilator circuit
attached to an endotracheal or a tracheostomy tube.
In summary, the literature shows that in intensive care settings, although the optimal schedule for the frequency of ventilator circuit
changes remains unknown, the first change may be safely delayed until the end of one week of mechanical ventilation.
The total gas flow rate was varied between 3 and 10 L/min through the ventilator circuit
or the special mixing apparatus to achieve 13 dwell times to investigate N[O.sub.2] formation.
The SV300, which is used conventionally for neonatal mechanical ventilation, detects [V.sub.T] at the expiratory valve; the PB840 also detects [V.sub.T] at the expiratory valve and compensates [V.sub.T] with the ventilator circuit
's volume increase calculated by the ventilator circuit
compliance; the EV4N detects [V.sub.T] at Y-piece.
* Following specifically-posted patient contact precautions As therapists we can also practice acceptable (preferably optimal) technique during such procedures as patient-ventilator checks, suctioning, ventilator circuit
changes, ventilator change-outs, sputum inductions, assisting our patients with deep breathing and coughing, extubations, arterial and other blood sampling and measuring procedures, pulmonary function testing, etc.
Reduced expiratory flow cannot be compensated for by most ventilators and could lead to substantially higher airway and intrathoracic pressures; increased end-expiratory pressures would not be detected by the pressure transducers in the ventilator circuit
Recommendations included establishing an oral care protocol, routine subglottic suctioning, HOB elevation 30[degrees]-45[degrees], and reducing the frequency of ventilator circuit
All product codes include a swivel connector to reduce torque to the patient and a 15/22 mm connector to accommodate various ventilator circuit
