This vital sign reflects how effectively the heart is pumping blood throughout the body.
What is blood pressure?
This is the volume of air exhaled during a normal breath.
What is tidal volume (VT)?
This ABG value represents the acidity or alkalinity of the blood.
What is pH?
This ventilator setting controls the number of breaths per minute the patient receives.
What is the respiratory rate?
When inspecting a patient’s chest, you notice asymmetric movement during breathing. What is this called?
What is flail chest or paradoxical breathing?
This oxygen delivery device provides a precise FiO₂ using air-entrainment ports.
What is a Venturi Mask?
This value represents the maximum volume of air that can be exhaled after a maximal inhalation.
What is vital capacity (VC)?
Interpret this ABG: Ph 7.21, PCO2 12, O2 98, HCO3 10
What is Metabolic Acidosis, (seen in diabetics)
This setting determines the volume of air delivered with each mechanical breath.
What is the tidal volume (VT)?
Fine crackles (rales) heard on auscultation are most commonly associated with which respiratory condition?
What is pulmonary edema or pneumonia?
At 3 L/min, a nasal cannula delivers approximately what FiO₂?
What is 32%?
Given the ABG results: pH 7.30, PaCO₂ 60 mmHg, HCO₃⁻ 26 mEq/L — identify the primary disturbance and whether it’s acute or chronic.
What is acute respiratory acidosis?
You observe a high-pressure alarm on the ventilator. List two possible causes.
What are secretions in the airway, patient coughing, kinked tubing, or decreased lung compliance?
A patient’s pulse oximetry reading suddenly drops from 96% to 84%. What is the first thing you should assess?
What is the patient’s airway, sensor placement, and oxygen delivery system?
This oxygen delivery system can provide up to 100% FiO₂ and includes a reservoir bag with a one-way valve.
What is a nonrebreather mask?
A reduced FEV₁/FVC ratio on spirometry indicates this type of lung disorder.
What is an obstructive defect?
The partial pressure of oxygen in the blood at which the hemoglobin is 50% saturated, typically about 26.6 mmHg for a healthy person
What is the P50
A patient’s ABG shows PaCO₂ 55 mmHg and pH 7.29 on volume control ventilation. What ventilator adjustment should you make?
What is increase the respiratory rate or tidal volume to improve alveolar ventilation?
While reviewing a patient’s arterial line waveform, you notice a dampened tracing. What are two possible causes?
What are air bubbles or clots in the line, loose connections, or catheter kinking?
How long will a full H cylinder last @ 2l/m
What is 52.33 hours
Which PFT measurement is most helpful in differentiating restrictive from obstructive lung disease?
What is TLC (Total Lung Capacity)?
How long should pressure be applied after an arterial stick?
What is until the bleeding has stopped?
You’re weaning a patient from mechanical ventilation. Name two parameters that indicate readiness to wean.
What are adequate oxygenation (PaO₂ > 60 mmHg on FiO₂ ≤ 0.4), RSBI < 105, stable hemodynamics, and good mental status?
