Ventilator Assistance, Air Leak Disorders Flashcards
The Provider orders the following mechanical ventilation settings for a patient who weighs 75kg. The Pt’s spontaneous respiratory rate is 22 breaths/min. Which arterial blood gas abnormality may occur if the pt continues to be tachypneic at these ventilator settings? Tidal Vol.:600mL; FiO2:0.5; Resp. rate: 14breaths/min; Mode assist/control; PEEP:10cm
Respiratory Alkalosis… Tachypneic can lower CO2 levels in the blood leading to alkalosis.
The nurse is assisting with endotracheal intubation and understands that the correct placement of the endotracheal tube in the trachea would be identified by?
Equal bilateral breath sounds upon auscultation
Position above the carina verified by CXR
Positive detection of CO2 through CO2 detector
Pt admitted to the progressive care unit with a diagnosis of community-acquired pneumonia. These were the ABGs obtained: pH 7.35; PaCO2 55mm, Bicarb 30; PaO2 65mm. These blood gases reflect:
Hypoxemia and compensated respiratory acidosis
pH is normal means compensated but closer to the acidosis side, PaCO2 at 55 means resp. acidosis.
PEEP is a mode of ventilatory assistance that produces the following condition
There is pressure remaining in the lungs at the end of expiration that is measured in cm H2O
A pt. is being mechanically ventilated in the synchronized intermittent mandatory ventilation mode at a rate of 4 breaths/min. His spontaneous respirations are 12breaths/min. He receives a dose of morphine sulfate, and his respirations decrease to 4 breaths/min. What adjustments may need to be made to the patient’s ventilator settings?
Increased the synchronized intermittent mandatory ventilation RR
The nurse is caring for a mechanically ventilated patient and notes the high pressure alarm sounding. The nurse cannot quickly identify the cause of the alarm and notes the patient’s oxygen saturation is decreasing and heart rate and respiratory rate are increasing. The nurse’s priority action is to
Manually ventilate the pt while calling for a respiratory therapist
The nurse is caring for a patient with an endotracheal tube. The nurse understands that endotracheal suctioning is needed to facilitate removal of secretions and that the procedure
is done as indicated by pt. assessment
The nurse notes that the patient’s arterial blood gas levels indicate hypoxemia. The patient is not intubated and has a respiratory rate of 22 breaths/min. The nurse’s first intervention to relieve hypoxemia is to
Notify the provider of the values and obtain a prescription for oxygen
Early sign of hypoxemia on the nervous system
Restlessness
The nurse is caring for a mechanically ventilated pt. and responds to a high inspiratory pressure alarm. Recognizing possible causes for the alarm, the nurse assesses which of the following?
Need for suctioning
Coughing or attempting to talk
Kinks in the ventilator tubing
A PaCO2 of 48 mm Hg is associated with
Hypoventilation (acidosis)
O2 saturation represents
Oxygen that is chemically combined with hemoglobin
Nasotracheal intubation is associated with a greater risk for:
Sinusitis and Infection
The nurse is caring for a pt whose ventilator settings include 15cm H2O of PEEP. What complication does the nurse assess the pt for?
Low cardiac output secondary to increased intrathoracic pressure
A pt. status worsens and needs mechanical ventilation. The pulmonologist wants the pt. to receive 10 breaths/min from the ventilator but wants to encourage the pt to breathe spontaneously between the mechanical breaths at his own tidal volume. This mode of ventilation is called:
Intermittent mandatory ventilation
