Day 4 -Rest day at Base Camp

Visit to camp doctor in the am for approval to proceed. Checking ox saturation level and blood pressure - mine is 95% and blood pressure is 120 / 80. Others generally ok but three needed to be retested after the carry tomorrow. Two for water on lungs and one for blood pressure.
Blood pressure seems to be the main concern with 160 being the limit. However, you appear to be allowed to keep going back until you pass and they will give you a pill to help lower your blood pressure - strangely this pill is only a short term measure and there is no requirement to carry on taking them higher up the mountain.

Anyway after a few visits, the whole group is cleared to proceed.The rest of day is sorting out food and kit to take up mountain.
