497 Possible Causes for Hypotension, Respiratory Alkalosis

  • Upper Respiratory Infection

    The risk of mortality is significant in patients who progress to streptococcal toxic shock syndrome, which is characterized by multiorgan failure and hypotension.[] Three to four hour polygraphic sleep studies were carried out in 10 infants, five with upper respiratory infection and five with metabolic alkalosis secondary to vomiting[] During upper respiratory infection, the main abnormality detected was brief (greater than 3 less than 6 seconds) or prolonged (greater than 6 seconds) attacks of obstructive[]

  • Heat Stroke

    The body compensates with acute respiratory alkalosis secondary to increased respiratory effort. This may in itself lead to heat‐induced tetany.[] In addition, pulmonary edema, coma, hypotension, and hyperpyrexia occurred.[] There were only 2 serious cardiac events (1 myocardial infarction and 1 hypotensive supraventricular tachyarrhythmia), neither of which were fatal or life threatening.[]

  • Sepsis

    Septic shock is defined as hypotension with a mean arterial pressure less than 65 mm Hg, requiring vasopressors despite adequate fluid resuscitation and/or lactic acid levels[] Patients with bacteremia from any source often display an increased breathing rate resulting in respiratory alkalosis .[] alkalosis Warm or cold skin, depending on the adequacy of organ perfusion and dilatation of the superficial vessels of the skin The following factors suggest an IV line infection[]

  • Acute Respiratory Distress Syndrome

    It is feasible that severe acidosis, hypotension, azotemia, hypoalbuminemia and the superimposed aggressive intravenous fluid administration were important risk factors for[] References: [8] [9] [10] Diagnostics Laboratory studies Arterial blood gas Initially, hypoxemic respiratory failure with PaO 2 and respiratory alkalosis ; PaO 2 / FiO 2 300[] A 54-year-old woman presented with fever, hypotension, and pancytopenia, with peripheral smear diagnostic of ehrlichiosis.[]

  • Septicemia

    Septic shock• Sepsis with– Hypotension, for at least 1 h, despite adequate fluidresuscitation– Need for vesopressor9 10.[] alkalosis Warm or cold skin, depending on the adequacy of organ perfusion and dilatation of the superficial vessels of the skin The following factors suggest an IV line infection[] Signs of established sepsis include confusion, metabolic acidosis (which may be accompanied by faster breathing and lead to a respiratory alkalosis ), low blood pressure due[]

  • Acute Liver Failure

    Metabolic: Metabolic and respiratory alkalosis may occur early. If shock develops, metabolic acidosis can supervene.[] Clinical examination showed an extensive coagulation disorder, diffuse hematomas, hypotension and tachypnea.[] Vascular: "Shock liver" from extreme hypotension, Budd-Chiari, Veno-occlusive disease 4.[]

  • Septic Shock

    hypotension, and both refractory hypotension and hyperlactatemia.[] When respiratory muscles fatigue the accumulation of serum lactate occurs. Metabolic acidosis (increased anion gap) supervenes the respiratory alkalosis.[] Whatever its cause, the high respiratory rate can cause a profound respiratory alkalosis that counterbalances lactic acidemia It may actually shift the patient's pH toward[]

  • Metabolic Alkalosis

    We describe a case of medication induced metabolic alkalosis in a maintenance dialysis patient who developed severe hypotension while undergoing a lactate hemofiltration procedure[] "Respiratory acidosis" caused by increased carbonic acid. 2. "Respiratory alkalosis" caused by decreased carbonic acid. 3.[] On this admission, the patient had recurrent bouts of vomiting induced by psychiatric eating disorder and showed severe volume depletion with hypotension, azotemia and metabolic[]

  • Syncope

    We reported a 75-year-old man who had recurrent syncope attacks secondary to hypotension and reduced plasma norepinephrine (NE) levels.[] Hysteria and hyperventilation do not fall in this category because they cause "light-headedness" through respiratory alkalosis brought on by blowing off carbon dioxide too[] The modifying influence of prolonged antihypertensive treatment on the tolerance to acute, drug-induced hypotension. Circulation 1976;53:720–727.[]

  • Theophylline

    In overdose, it causes hypotension, bradycardia and drowsiness.[] Arterial blood gas analysis revealed a mixed metabolic acidosis and respiratory alkalosis. Serum lactate level was 51 mmol/L (normal 0.7-2.1 mmol/L).[] alkalosis.[]
