Ventilator Management
This formula allows clinicians to calculate a desired tidal volume, frequency, or minute ventilation.
What is the Have-Want formula?
What is the most important criterion in assessing readiness for weaning?
Reversal of the disease state or condition that required mechanical ventilation.
These are the components of VAP bundles.
HOB elevation 30-45°; daily awake and breathe trials; the use of subglottic suction ETT; and, scheduled, frequent oral care are all components of this.
These patients require a short inspiratory time to allow for exhalation. (Pick two groups)
Who are COPD and asthma patients?
PADIS recommends this mode of ventilatory support for sleep.
What is Assist/Control (A/C)?
This type of ABG abnormality is corrected by first decreasing the respiratory rate, then decreasing tidal volume, assuming the tidal volume is appropriate for the patient's height.
What is a respiratory alkalosis?
The average length of a spontaneous breathing trial.
What is 30 - 120 minutes?
What is a Ventilator-Associated Condition (VAC)?
The first tier in surveillance, the condition where the patient demonstrated at least two days of clinical stability or improvement, followed by at least two days of worsening oxygenation.
This is the reason that noninvasive ventilation (NIV) is used for patients in congestive heart failure (CHF).
To allow time for pharmacologic intervention to become effective.
The first priority when a ventilator alarm sounds.
Is my patient oxygenating and ventilating?
100 - 120, no greater than 150 cm H2O pressure.
What is the appropriate vacuum pressure for ET suctioning a mechanically ventilated adult?
The acceptable range for Rapid Shallow Breathing Index (RSBI).
What is 60 - 105 breaths/min/L?
These factors influence the mortality rate for VAP.
This is dependent on the infecting organism, the presence of underlying disease, and prior antimicrobial therapy.
This evidence-based study recommends a lung protective ventilation strategy using low tidal volumes and high respiratory rates.
What is ARDSNet?
This is an absolute contraindication for PEEP.
What is an untreated pneumothorax?
Common causes of metabolic alkalosis.
Nasogastric suctioning, furosemide administration, and potassium deficiency.
Which patient populations should be considered for extubation to noninvasive ventilation (NIV)?
Patients with chronic respiratory disease, cardiac disease, or prolonged ventilatory requirement.
When considering humidification, this method may reduce VAP rates.
What are HMEs?
This technique is sometimes used clinically for patients with closed head injury to reduce intracranial pressure (ICP).
What is iatrogenic hyperventilation?
What is the unaffected lung in the dependent position?
"Good lung down"
What are common effects of increased PaCO2 associated with Permissive Hypercapnia?
Cerebral vasodilation, hypoxemia, HbO2 dissociation curve shift to the right, and increased drive to breathe.
When laryngeal edema is identified post-extubation and the patient is not in distress, this is the most appropriate primary intervention.
What is 2.25% racemic epinephrine administered via nebulization?
These are aerobic gram-negative bacteria which typically represents 60% of all VAP cases. (Choose four)
What are Pseudomonas aeruginosa, Klebsiella pneumonia, Escherichia coli, and Acinetobacter?
According to the Belin Definition, a PaO2/FIO2 ratio of 201 - 300 on a PEEP of at least 5 cm H2O.
What is Mild Acute Respiratory Distress Syndrome (ARDS)?
If a respiratory therapist notes the low-pressure, low tidal volume, and low minute volume alarms are sounding on the ventilator, this should be the suspected cause.
What is a leak in the patient-ventilator system?
