Why did IPPB lose favor among the clinical practice and what did that make way for?
people found that the benefits were overstated and could be accomplished using simplier, more cost effective devices (CPAP)
aerosolized medication delivery
Patients that exhibit acute cardiogenic pulmonary edema, where do we start their pressures, what is their recommended starting pressures?
Symptoms of Chronic Hypoventilation include what?
A patient with what is initially treated with CPAP, if hypoventilation nocturnal desaturations persist what is recommended?
Patient with: OSA (obstructive sleep apnea)
Recommended: NIV (improve gas exchange)
Exclusion criteria for NIV, list four
respiratory arrest or the need for intubation
inability to protect airways
What is the mode of ventilator choice for chronic respiratory failure that is caused by restrictive thoracic disorders?
NIV for patients who can protect their own airways
Acute care setting, overwhelming evidence will support the use of NIV in what type of patient?
When facilitating weaning from NIV as an adjunct therapy. What patient population is it shown to be most beneficial with?
patients who suffer from chronic illness (e.g. COPD)
Three types of ventilations when implying NIV will include what LIST
portable homecare ventilators
adult acute care ventilators
portable pressure support ventilators
Respiratory failure with selection criteria, pH and PaCO2 ranges what are they?
pH < 7.35
PaCO2 > 45
PaO2/FiO2 < 200
Final consideration with selection of patients with ARF is the what of the disease process?
NIV is considered a form of life support with patient with a DNI order T/F
Pressure support ventilations: CPAP, PSV, Bilevel vent are what type of ventilation?
In all modes of BiPAP, patient delivered tidal volume depends on what settings?
difference between IPAP and EPAP
"gradient between the IPAP level and the EPAP, the inspiratory time, patient inspiratory effort, and the patients lung characteristics (airway resistance and lung compliance)"
Physiological benefits of NIV, what are they?
improve gas exchange (by resting respiratory muscles)
reduced diaphragmatic pressure swings
reduces WOB on initial inspriation
