Flashcards in Resp Failure Deck (28):
WHat is Respiratory Failure?
Lungs fail to adequately oxygenate arterial blood and/or Prevent retension of CO2
Consequence of underlying conditions
WHat is Acute Respiratory Failure?
Abrupt onset with rapid progression
WHat is Chronic Respiratory Failure?
Slow onset and progression
What is Acute on ChronicRespiratory Failure?
increased baseline O2 requirements
Increase CO2 above baseline enough to drop pH
What are ventilation causes of Acute Resp Failure?
What are oxygenation causes of Acute Resp Failure?
What are ventilation causes of Chronic Resp Failure?
What are oxygenation causes of Chronic Resp Failure?
WHat are the types of Respiratory Failure?
Hypoxemic Resp Failure
Hypercapnic Resp failure###
What are the causes of Hypoxemia?
What are the clinical Manifestations of Tissue Hypoxia?
Other Organ Failure
What are common conditions that Can lead to Resp Failure?
Pulm infection or Aspiration
Obstructive Lung disease
What is the P/F Ratio
Ratio of Oxygen delivery to Arterial Oxygen
What is done to give initial support to a Pt in Resp Failure?
Vital Sign monitoring
What drugs are given to Support someone in resp failure?
Vasodilators in CHF
What are the goals in Advanced support in Resp Failure?
Hb Conc > 7
Goal Lactic Acid
WHat are the affects of CO2 on pH?
Acute rise of 10 = dec pH by 0.08
Acute drop of 10 = raise pH by 0.08
Chronic rise of 10 = dec pH by 0.03
Chronic drop of 10 = Raise pH by 0.03
What are the effects of CO2 changes on Bicarb concetrations?
Acute Resp Acidosis: CO2 +10 = Bicarb +1
Chronic Resp Acidosis: CO2 +10 = Bicarb +3
Acute Resp Alkalosis: CO2 -10 = Bicarb -2
Chronic Resp Alkalosis: CO2 -10 = Bicarb -5
What is the treatment of Chronic Respiratory Failure?
Supportive Care and ED
Nutrition (wt loss/gain)
What are the vaccines that COPD patients need to recieve?
What are the effects of oxygen therapy in COPD?
Improves survival, dyspnia, and Exercise Tolerance
No improvement in Lung function, or survival in Pts with Moderate or nocturnal Hypoxemia
What qualifies someone for Oxygen therapy?
What are the Absolute Contraindications for Lung Transplant?
Major organ dysfunction
Non-osteoporotic musculoskeltal disease
What are the Relative Contraindications for Lung Transplant?
Systemic or Multisystem dz
WHat are signs of Chronic Respiratory failure?
Nomral pH w/ elevated PaCO2
What are adverse effects of O2 administration in someone with Respiratory failure?
increased physiologic dead space from V/Q mismatch
Attenuated hypoxic ventilatory drive
What is the Haldane effect?
Deoxygenation of the blood increases its ability to carry carbon dioxide.
Conversely, oxygenated blood has a reduced capacity for carbon dioxide.
