What is Tidal Volume (VT)?
The amount of air delivered to the lungs with each breath.
Typical start value is 6–8 ml/kg ideal body weight. Use 6 ml/kg in ARDS for lung protection.
What is the typical start value for Tidal Volume (VT)?
6–8 ml/kg ideal body weight.
Use 6 ml/kg in ARDS.
What is the purpose of Tidal Volume (VT)?
Prevent volutrauma (alveolar overdistention).
Important in managing patients with ARDS.
What is the definition of Respiratory Rate (RR)?
Number of breaths the ventilator gives per minute.
Typical start value is 12–16 breaths per minute.
What is the typical start value for Respiratory Rate (RR)?
12–16 /min.
This range helps in adequate ventilation.
What is the purpose of adjusting the Respiratory Rate (RR)?
Controls CO₂ removal by adjusting minute ventilation.
High RR reduces CO₂; low RR increases CO₂.
What does FiO₂ stand for?
Fraction of Inspired Oxygen.
It is the oxygen concentration delivered to the patient.
What is the typical start value for FiO₂?
Start at 100% (FiO₂ = 1.0), reduce ASAP.
This is to avoid oxygen toxicity.
What is the purpose of FiO₂?
Avoid oxygen toxicity and absorptive atelectasis.
Target SpO₂ is 92–96%; keep FiO₂ < 60% when possible.
What is PEEP?
Positive End-Expiratory Pressure.
It is the pressure maintained in the lungs at the end of exhalation.
What is the typical start value for PEEP?
5 cm H₂O (can go higher in ARDS).
Higher PEEP helps prevent alveolar collapse.
What is the purpose of PEEP?
Prevent alveolar collapse; improve oxygenation.
Excess PEEP can cause barotrauma or hypotension.
What does the Inspiratory Time / I:E Ratio represent?
The ratio of inspiratory to expiratory time.
Typical start value is 1:2, adjustable based on patient needs.
What is the typical start value for the Inspiratory Time / I:E Ratio?
1:2 typically.
Adjust for oxygenation or air trapping.
How should the I:E ratio be adjusted for COPD?
Lengthen expiration (1:3 or 1:4).
This adjustment aids in preventing air trapping.
How might the I:E ratio be adjusted for ARDS?
May use 1:1.
This helps improve oxygenation in ARDS patients.
