Complete Solutions
A anesthesiologist will most commonly intubate a patient. What
two items will the anesthesiologist need to intubate? Correct
Answer - Laryngoscope (check light) or Glidescope -> rigid
stylet
- 10 mL empty syringe (used to inflate the balloon)
Alterations of the gas exchange unit Correct Answer
Oxygenation failure - Type 1
- Perfusion might be compromised
- Pulmonary capillary bed dysfunction
In either case, blood is not oxygenated sufficiently
BiPAP uses 2 different settings that include 2 differing
pressures:
1. An _____ pressure to help remove CO2
2. An _____ pressure to keep alveoli open and improve O2
Correct Answer 1. Inspiratory
2. Expiratory
Define:
Percentage of hemoglobin saturated with oxygen Correct
Answer Oxygen saturation
How do you confirm placement of the endotracheal tube?
Correct Answer - Listen to lungs
- Listen to stomach (no gurgling)
, - Chest xray
-> Confirms height
-> Will not confirm if it's in the trach or esophagus
In chronic respiratory failure, what three things will you see
with your patient? Correct Answer - Absence of acute
symptoms
- Chronic low pH (always on acidic side of normal: 7.35-7.4)
- Develop tolerance to hypoxemia and hypercapnia
*These patients can still develop acute on chronic respiratory
failure
In Hypercapnic acute respiratory failure, the PaCO2 (partial
pressure of carbon dioxide) would be > _____ mmHg and the
pH would be < ______. Correct Answer PaCO2: > 45 mmHg
(Normal: 38-42)
pH: < 7.35 -> Acidic
In Hypoxemic acute respiratory failure, the PaO2 (partial
pressure of oxygen) would be < ______ mmHg on RA and the
SaO2 (oxygen saturation) would be < _____% on RA. Correct
Answer PaO2: < 60 mmHg (Normal: 80-100)
Sao2: < 90% (Normal: 96-98%)
In ventilatory failure - type 2, why does hypercapnia develop?
Correct Answer Ventilation rates decrease to < 4-6 L/min
(holding onto Co2)
