Low oxygen levels in the blood |
Hypoxemia |
|
Degree of hypoxemia can be calculated using the ___ |
A-a gradient |
|
The difference between the alveolar oxygen pressure and the arterial oxygen pressure |
A-a gradient |
|
Hypoxemic Respiratory failure is defined as PaO2 < ___ mmHg SpO2 < ___% |
55 mmHg; 88% |
|
Goals of oxygen therapy? |
SaO2 > 88% PaO2 > 55-60 (measured with ABG) |
|
Contraindications to Oxygen Therapy |
Severe COPD |
|
Oxygen delivery devices that include nasal prongs, face masks and masks with reservoirs. They are indicated for patients with normal breathing patterns, depth and rate. When minute ventilation exceeds the slow rates of these devices, the oxygen reservoir is drained, and room air is inhaled for additional demands. |
Low-flow delivery systems |
|
Oxygen delivery devices that provide complete control of inhaled gas mixtures and deliver constant FiO2. They are not effected by changes in ventilatory patterns. A high velocity stream is created by passing oxygen through a narrowed orifice. It is indicated for abnormal breathing patterns, depth and rate. Examples include aerosol masks, trach masks, venti masks and face tents. |
High-flow delivery systems |
|
Waveforms in pulse oximetry should have what? |
A dicrotic notch |
|
Pulse oximetry is based off of what? |
Spectrophotometry |
