Indication for respiratory therapy |
Hypoxia dyspnea increased myocardial work |
|
|
Complications of oxygen therapy |
Respiratory depression hypoxic drive atelectasis oxygen toxicity retrolental fibroplasia |
|
|
Dyspnea symptoms |
Nasal flaring intercostal retractions increased frequency |
|
|
Hypoxia symptoms |
Cyanosis low saturation 92 or below increased work if breathing tachycardia 1st symptom |
|
|
Increased myocardial work |
Increased heart rate increased blood pressure chest pain ekg abmornalies normally 60-100 |
|
|
Atelectasis |
60% or higher high oxygen=nitrogen washout changing contents push nitrogen out put in oxygen collapse FIO2 24-48 hours cause atelectasis without nitrogen give positive pressure |
|
|
Oxygen toxicity |
<60% high level toxic to lung tissue type 1 alveolar cell |
|
|
Retrolental fibroplasia |
Baby blindness pao2> 80 torr nitrogen high partial pressure |
|
|
Air oxygen ratio |
100-fio2/fio2-20=part of at entrained/1 part oxygen use 21 on percentages higher than 40% |
|
|
Calculating total flow |
Air oxygen ratio adding the numbers than multiplying the sum by the O2 liter flow |
|
|
3 ways to meet inspiratory demand |
Horns double nebulizer high flow Misty ox |
|
|
Define low flow |
Does not meet patients inspiratory demands therefore room air is entrained causing a variation with the fio2 |
|
|
Normal inspiratory flow |
25-30 liters per minute |
|
|
1-6lpm. for every lpm increase in flow the FIO2 increased by 3-4% 4 liters and above give humidity |
Nasal cannula |
|
|
2 psi pop off with |
Regular humidifier |
|
|
6 psi pop off |
7-15 lpm |
|
|
24-45% FIO2 1-6 flow rate goes posterior |
Nasal catheter |
|
|
Flow delivered.25-2 lpm occlusion=problem |
Transtracheal O2 catheter |
|
|
20cc if oxygen 6-12 lpm no humidity O2 conserve |
Oxymiser |
|
|
20cc of oxygen conserving device |
Pendant cannula |
|
|
Minimum of 5 lpm liter flow 6-10 40-55% FIO2 |
Simple mask |
|
|
60-80 FIO2 keep bag full and frequency volume and flow |
Partial rebreather |
|
|
No room air oxygen specific attached to nebulizer except Venturi mask and nonrebreather |
High flow |
|
|
95-100% FIO2 3 valves remove valves used when delivering heliox |
Non rebreather |
|
|
O2 specific COPD patients 24-40 FIO2 90% for COPD patients |
Venturi |
