Unexpected, no obvious cause (may occur from blebs, pneumonia, neoplasms)
Commonly in the apex, smaller and will heal on its own if symptoms are treated

1 Oxyhemoglobin Dissociation Curve 2 High V/Q ratio
3 Causes of the OD Curve to shift right 4 Spontaneous Pneumothorax

Terms in this set (105)
Oxyhemoglobin Dissociation Curve Shows the relationship between O2 disolved in the blood
(PO2) and O2 attached to Hgb
Effect that partial pressure has on Hgb saturation
Job of Hgb to refresh the PO2 as it gets used by the tissues
90-60 Relationship 90% saturation of O2 = partial pressure of 60
OD Curve shifts to the right Decreased affinity of hemoglobin for O2--> more O2 available
for cells
Causes of the OD Curve to shift right Acidosis, high PCO2 levels, increased temperature, high levels
of 2,3-DPG (helps disassociate O2)
OD Curve shifts to the left Increased affinity of hemoglobin for O2
Less O2 available for cells
, Causes of the OD Curve to shift left alkalosis, low CO2 levels, decreased temperature, low levels
of 2,3-DPG
Ventilation (V) alveolar; 4L/min
Perfusion (Q) cardiac; 5L/min
Normal V/Q ratio 0.8-0.9
Low V/Q ratio (<0.8) Inadequate ventilation/ well-perfused lungs
"shunting"
Causes of Low V/Q ratio Atelectasis, Asthma (bronchoconstriction) Pulmonary Edema,
Pneumonia
High V/Q ratio (>0.8) adequate ventilation/ poor lung perfusion
"alveolar dead space"
Causes of high V/Q ratio Pulmonary Embolism, shock
Shutting flows through alveoli but picks up no O2
Alveolar dead space good O2, content with no blood flowing through
Hypoxemia reduced oxygenation of arterial blood
Causes of Hypoxemia Decreased FiO2% Hypoventilation, problems with diffusion
through the alveolar capillary membrane, problems in
perfusion of pulmonary capillaries
General S/sx of Pulmonary Disease Cough (acute or chronic)
Dyspnea (subjective sensation of uncomfortable breathing)
Orthopnea ( dyspnea when lying down)
S/sx of Pulmonary Disease Pain, Abnormal sputum, hemoptysis, hypoventilation,
hyperventilation, cyanosis, clubbing
Clubbing a sign of chronic hypoxia
distorted angle of a nail bed
S/sx of Upper Respiratory Viral Infections nose, sinuses, oropharynx, larynx may be affected
-common cold: self-limiting, increased secretions,
inflammation of throat, headache, fatigue
-viruses spread by contact
(rhino)sinusitis may be viral or bacterial: acute, subacute, chronic
Lower Respiratory Infections Bronchi, lungs affected
-influenza, pneumonias, tuberculosis, fungal infections
Pathophysiology of Influenza viral infection that can affect upper and lower respiratory tract
-3 types (A,B,C)
Characteristics of Pandemic Influenzas easily spread with high morbidity spread through inhaling
droplets
