26 Possible Causes for Muscle Mass Decreased, PaO2 Decreased

  • Morbid Obesity

    Linezolid serum concentrations were obtained and vancomycin was reinstituted, after which the patient began to improve (afebrile, improving PaO2/FiO2 ratio, decreasing leukocytosis[ncbi.nlm.nih.gov] In addition, the amount of muscle in your body tends to decrease with age. This lower muscle mass leads to a decrease in metabolism.[mayoclinic.org]

  • Obesity

    In elderly patients, obesity induces a decrease in skeletal muscle strength and mass, which is linked to age-related sarcopenia.[ncbi.nlm.nih.gov] mass, decreasing in starvation and increasing during resistive activity when sufficient protein was ingested.[doi.org] Because muscle enlargement is absent or minimized when loads are not lifted, even with adequate nutrition, we postulate that some of the genes or genotypes by which resistance[doi.org]

  • Chronic Obstructive Pulmonary Disease

    Symptoms include the following: Productive cough or acute chest illness Breathlessness Wheezing Systemic manifestations (decreased fat-free mass, impaired systemic muscle[emedicine.medscape.com] It can lead to a reduction in diaphragmatic mass with a decrease in strength and endurance of the respiratory muscles ( Arora 1982 ; Fiaccadori 1992 ).[doi.org] Many patients with COPD may have decreased fat-free mass, impaired systemic muscle function, osteoporosis, anemia, depression, pulmonary hypertension, cor pulmonale, and even[emedicine.medscape.com]

  • Chronic Bronchitis

    88-92% (PaO2 of 60-70).[clinicaladvisor.com] Smoking cessation does not change smooth muscle mass and fibrosis in the peripheral airways; however, it improves peripheral airway collapse in the single-breath nitrogen-washout[doi.org] Therefore, to decrease the likelihood of severe hypercapnea, a safe target oxygen saturation for patients with severe COPD and acute-on-chronic respiratory failure is between[clinicaladvisor.com]

  • Obstructive Sleep Apnea

    Adults with normal body mass indices (BMIs) often have decreased muscle tone causing airway collapse and sleep apnea.[en.wikipedia.org]

  • Preeclampsia

    […] skeletal muscle mass and subcutaneous fat tissue • Loose, dry, and easy peelable skin • Long finger nails • Relatively large hands and feet compared to body • Skin having[doi.org] […] anterior fontanelle (poor formation of membranous bones) • Absent buccal fat (old man look) • Small or scaphoid abdomen • Thin umbilical cord often stained with meconium • Decreased[doi.org]

  • Hypoxia

    In case of pathophysiological hypertrophy the cardiac angiogenesis does not keep up with the increased muscle mass resulting in decreased blood supply.[herzzentrum-goettingen.de] In case of physiological hypertrophy – as a consequence of for example endurance exercise – cardiac angiogenesis and cardiac muscle mass are balanced.[herzzentrum-goettingen.de]

  • Aspiration Pneumonia

    From the back of the tongue the mass is propelled by the tongue to the muscles of the pharynx.[americannursetoday.com] Poor dentition can decrease chewing efficiency, thus fostering pocketing on the side of the mouth. Pocketed food can later be aspirated.[americannursetoday.com]

  • Accidental Hypothermia

    , decreased PAO2 and PaCO2 due to increased gas solubility, increased dead space, diaphragmatic fatigue, metabolic acidosis - pulmonary hypertension GI: decreased hepatic[lifeinthefastlane.com] Such risks may be compounded by ineffective vasoconstriction and decreased subcutaneous fat, total body water, and muscle mass, which are also frequently seen in advanced[nursingcenter.com] Q and MAP, vasoconstriction, ECG – widening of QRS, increased PR and QT, J waves, risk of VF 28 C, increased blood viscosity and myocardial work RESP: decreased CO2 production[lifeinthefastlane.com]

  • Cystic Fibrosis

    Manifestations include the frequent passage of bulky, foul-smelling, oily stools; abdominal protuberance; and poor growth pattern with decreased subcutaneous tissue and muscle[merckmanuals.com] mass despite a normal or voracious appetite.[merckmanuals.com]
