COPD & NIV Management
The restricted target SpO2 titration range for a patient experiencing an acute exacerbation of COPD to prevent suppressing their hypoxic drive.
What is 88% to 92%?
The strict physiological parameter that must always be used to calculate a patient's target initial tidal volume on a ventilator, rather than their actual body weight.
What is Ideal Body Weight (IBW)?
The absolute gold standard device and corresponding monitor tracing utilized immediately after an intubation attempt to definitively confirm correct tracheal placement.
What is inline waveform capnography (EtCO2 displaying a square-wave profile)?
Normal hospital central medical gas pipeline systems run at this standard regulated line pressure parameter.
What is 50 psi?
The immediate, foundational BLS protocol step required when a therapist enters a patient's room to deliver a routine nebulizer treatment and finds the patient unresponsive, cyanotic, and pulseless.
What is activating the emergency response system and starting immediate chest compressions/CPR?
This initial oxygen delivery device is preferred for a severely hypoxemic COPD patient because it provides precise FiO2 control and meets or exceeds variable inspiratory flow demands.
What is a High-Flow Nasal Cannula (HFNC)?
The lung-protective strategy threshold for maximum allowable Plateau Pressure (Pplat) to prevent structural alveolar over-distension and barotrauma in ARDS patients.
What is ≤30 cmH2O?
The immediate corrective action an RT must take if waveform capnography registers a value of 0 mmHg and displays a completely flat trace following oral intubation.
What is deflating the cuff, pulling the tube out (esophageal intubation), and resuming bag-valve-mask ventilation with 100% O2?
According to Westgard quality control rules, a blood gas analyzer whose control data falls more than 2 standard deviations (SD) outside of the mean for 3 consecutive runs is demonstrating this type of operational error.
What is a systematic error (or an "out-of-control" situation)?
This pre-procedural respiratory action is the cornerstone of the RT's role during emergency rapid sequence intubation (RSI) to maximize safe apneic time and prevent rapid desaturation.
What is pre-oxygenating the patient with a bag-valve-mask system (equipped with a PEEP valve) at an FiO2 of 1.0 for 3 to 5 minutes?
According to GOLD guidelines, this absolute primary contraindication must be ruled out by the clinician before attempting a non-invasive positive pressure ventilation (BiPAP) trial.
What is the inability to protect the airway? (e.g., absent gag reflex, active vomiting, or copious unmanageable secretions)
If a patient's Peak Inspiratory Pressure (PIP) increases significantly but their Plateau Pressure remains perfectly stable, it indicates this specific type of clinical complication.
What is an increased Airway Resistance problem? (e.g., patient biting the tube, bronchospasm, or excess secretions)
This catastrophic air-trapping emergency will occur if an RT places a one-way speaking valve (e.g., Passy Muir) on a tracheostomy tube without performing this mandatory step first.
What is completely deflating the tracheostomy cuff?
The direct corrective action required when a blood gas analyzer is flagged with a systematic out-of-control error profile.
What is taking the machine offline, calibrating/repairing it, and verifying with a clean control run before processing patient samples?
An unexpected, catastrophic event where an ICU patient wakes up confused and pulls their own endotracheal tube out while the cuff is still fully inflated.
What is an unplanned self-extubation?
Standard starting BiPAP settings of IPAP 14 cmH2O and EPAP 6 cmH2O provide this specific level of Pressure Support (PS) to expand tidal volume and clear excess CO2.
What is 8 cmH2O? (PS=IPAP−EPAP)
The target initial tidal volume range per kilogram of IBW recommended when establishing lung-protective ventilation parameters for a patient with severe ARDS.
What is 6 mL/kg? (or a range of 4 to 6 mL/kg)
If an RT is called to a patient's bedside because a tracheostomy tube has become completely dislodged and a suction catheter cannot be passed, this is the first priority rescue action to stabilize the patient's dropping saturations.
What is initiating manual bag-valve-mask ventilation with 100% oxygen?
To safely pass a spontaneous breathing weaning parameter screen, the patient's calculated Rapid Shallow Breathing Index (RSBI) must fall below this specific numeric value.
What is 105? (Calculated as Respiratory Rate / Tidal Volume in Liters)
This clinical bedside assessment procedure is performed when a patient with a severe anoxic brain injury shows signs of brain death to evaluate if the brainstem is still capable of driving respiration.
What is an apnea test?
This blood gas interpretation rule states that when setting up initial ventilator parameters for a newly intubated chronic COPD retainer, you should target their baseline parameter rather than a standard normal of 40 mmHg.
What is matching the patient's chronic baseline PaCO2?
The unique weaning protocol used for patients on Airway Pressure Release Ventilation (APRV) where the therapist systematically decreases the upper pressure limit while lengthening the time spent at that pressure.
What is the "Drop and Stretch" protocol?
When a pediatric patient presents with severe stridor, intercostal retractions, and a lateral neck radiograph showing a classic "thumbprint sign," this is the definitive, safest environment to manage their airway.
What is the Operating Room (OR) under controlled general anesthesia?
To confirm adequate respiratory muscle strength during a weaning screen, the measured Maximum Inspiratory Pressure (MIP) or Negative Inspiratory Force (NIF) must be more negative than this threshold.
What is −20 cmH2O? (e.g., −25 to −30 cmH2O)
During a formal bedside apnea test, this clinical finding on a post-procedure arterial blood gas confirms a positive result for brain death if the patient fails to make any spontaneous respiratory efforts.
What is a PaCO2 that increases to ≥60 mmHg (or ≥20 mmHg above their baseline)?
