Saturación arterial de oxígeno durante la ascensión a una montaña de más de 8.000 metros

Abstract: During expeditions to mountains higher than 8,000 metres, mountaineers have extremely low values of SaO2, similar to those of patients with severe respiratory failure. SaO2 increases progressively with acclimatization. SaO2 on the summit could have been relatively high, probably because of hyperventilation.

“…For other scenarios where patients have experienced changes in SpO 2 , including emergency care in helicopters, SpO 2 has been shown to decrease from 98% at 10,000 ft to 90% and 22,000 ft [23]. Similarly, ascending to high altitudes or camping in the mountains can also result in a significant decrease in SpO 2 levels, with a decrease of 68.0 + 9.3% at altitudes over 26,000 ft [24]. A study using multiple saturation meters would be valuable, as the literature only includes the use of a single oxygen saturation meter.…”

“…Los valores mínimo y máximo normal de saturación medida por oximetría de pulso durante la respiración regular de los recién nacidos (RN) de término a nivel del mar son de 97 a 100% y en los RN pretérmino de 95 a 100%. Estas características las convierten (FR y OXM) indispensables en la valoración de pacientes con enfermedades agudas y crónicas (sepsis, traumatismos, hemorragias, posoperatorios, estados dolorosos, convulsiones, EPOC, asma, cardiopatías incluidas las coronariopatías, etc) 24,33,52 Características de la oximetría Se utiliza en la clínica desde 1984. Da una confiabilidad del oxímetro de pulso de acuerdo con una sensibilidad de 100% con especificidad baja, ambas para detectar PaO2 mayor de 90 mmHg.…”

“…El oxímetro de pulso o pulsioxímetro es una herramienta de importancia clínica (1) al ser indicado en protocolos estándar de pacientes sometidos a procedimientos anestésicos y hospitalizaciones (2)(3)(4)(5)(6). Se usa principalmente para el monitoreo de saturación de oxígeno con el fin de prevenir niveles subóptimos de oxígeno arterial y complicaciones en pacientes con riesgo de hipoxia (7,8).…”
