A 38-year-old man was recently diagnosed with ARDS and underwent recruitment maneuver. Which of the following the respiratory therapist noticed after the procedure?
SaO2 increased to 91%
FiO2 increased to 0.6
pH drop to 7.30
PaCO2 increased to 60
Which of the following indicates that a patient is ready to be weaned
PaO2 is 80mmHg on 30% O2
The patient has active infections
Systolic BP is 190 mm Hg
PaO2/ FIO2 ratio is 100
A respiratory therapist would consider terminate SBT under which of the following circumstances?
The patient obtained sustained RR of 15 breaths/min
The SpO2 droped from 94% to 82%
The systolic blood pressure decreases from 150 to 135 mm HgThe systolic blood pressure decreases from 150
The heart rate decreases from 90 to 80 beats/min
A 40-year-old woman is admitted to the Emergency Department due to difficulty of breathing. She has a history of emphysema. Physical examination showed decreased tactile fremitus, hyperresonant, accessory muscle use, desaturation, and wheezing.
Which of the following is the most appropriate device?
Simple face mask
Non-Rebreathing Mask
Venturi Mask
Nasal cannula
A 38-year-old man with a history of COPD brought to the Intensive Care Unit. He was mechanically ventilated on ACVC mode. Two days later the respiratory therapist checked the ventilator waveforms and found the following waveform:
What dose this waveform indicate?
Overdistension
Low lung compliance
High airway resistance
Air trapping
How does patient positioning contribute to improving gas exchange and reducing the risk of hypercapnia and hypoxemia in patients with respiratory insufficiency?
By increasing fluid intake
By improving lung expansion and ventilation-perfusion matching
By reducing heart rate
By increasing red blood cell production
In what clinical scenarios and for which patient populations is manual ventilation, specifically bag-valve-mask ventilation, indicated as a strategy to optimize gas exchange and prevent hypercapnia and hypoxemia, and what are the key considerations and challenges associated with its implementation?
Only in pediatric patients
Only in patients with mild respiratory distress
In various clinical scenarios and for patients unable to breathe adequately or requiring respiratory support
Only in patients with chronic obstructive pulmonary disease (COPD)
What is the purpose of adjusting the inspiratory-to-expiratory ratio (I:E ratio) in mechanical ventilation, and how does it impact gas exchange and patient ventilation?
To increase tidal volume during inspiration
To decrease respiratory rate
To optimize gas exchange and prevent air trapping
To improve lung compliance
Which medical condition is the primary indication for CPAP?
CHF with pulmonary edema
Acute MI
COPD, prior to the use of bronchodilators
Unconscious Asthma
